The Best DaVinci IQ3 and IQC Accessories: Batteries, Mouthpieces, Dosage Pods, Water Tools and Spares

DaVinci builds its portables out of a small number of precise parts, and every one of them comes out. The oven lid carries a screw-adjusted zirconia pearl. The vapor path is a removable ceramic flavor chamber. The mouthpiece lifts off and swaps for a water tool adapter. The battery slides out of a door in the base. That design is why the DaVinci IQ3, IQC, IQ2 and IQ Core have a deeper accessory catalog than almost any other conduction portable, and why an owner can keep one running for years on spares that cost $8 to $12.

This guide covers everything DaVinci currently sells for the IQ family, plus the third-party glass and adapters that fit, sorted by what each part changes about a session. Where the MIQRO-C shares a part we say so, and where it needs its own version we say that too. Prices were checked in September 2026 at DaVinci's own store, Headshop.com, To The Cloud, The Stash Shack and Smoke Cartel, and are correct at the time of writing. If you are still choosing a model, our DaVinci vaporizers collection compares the range. If you already own one, start with the Quick Picks and the primer that follows, because most money wasted on DaVinci accessories goes on parts that fit a different model.

How the IQ Series Fits Together

Every accessory decision gets easier once you can name the parts, and the IQ family shares a layout from the original IQ through to the IQ3. From the bottom up:

• Battery door and cell. A magnetic door in the base covers a single removable lithium cell. The IQC, IQ2 and IQ Core take an 18650. The IQ3 takes the larger 21700. The MIQRO-C takes a stubby 18350. None of these interchange.
• Oven, lid and pearl. The glass-lined ceramic oven sits at the bottom of the device, which is why the mouthpiece end stays cool. The hinged lid carries the pearl, a zirconia ball on a threaded silicone post. Screw it in and the oven shrinks by about half, so a small load still packs tight against the walls, which conduction needs. The pearl and its gasket are the parts that wear.
• Flavor chamber. Vapor leaves the top of the oven through a narrow zirconia passage and into the flavor chamber, a removable ceramic tube that runs up the inside of the body to the mouthpiece. On the IQ2 and IQC it has a silicone lid. On the IQ3 it is longer and houses the Cool Core, a ribbed zirconia and glass helix that adds cooling surface.
• Mouthpiece. Magnets hold a flat mouthpiece over the top of the flavor chamber. Lift it off and drop on the extended version, which is also the 10mm water tool adapter. The IQ2, IQ3 and IQ Core ship with zirconia mouthpieces; the IQC ships with a polymer one that DaVinci calls silicone.
• Air dial. The IQ2 and IQ3 have an adjustable airflow dial on the base; the IQC and IQ Core have fixed airflow, which matters most through water.

The IQ Core arrived in May 2026 with the IQC's body, so IQC parts are the ones to look for when a listing does not name the Core. DaVinci had added the Core to its mouthpiece, pearl and glove listings when we checked but not yet to the flavor chamber, dosage pod or extract kit pages, and we flag that in each section rather than guess.

Batteries and Charging: The Upgrade That Removes the Wait

A DaVinci runs about an hour of continuous heating on a full cell, which our IQC review put at around half a dozen sessions and our IQ2 review at roughly the same. That is fine for a day out and not fine for a shared device or an owner who lets it idle at 400F. A second cell and a way to charge it outside the device turns a one-hour vaporizer into one that never stops. Our guide to vaporizer battery life covers the habits that stretch a cell; these are the parts.

Why the IQ3 moved to a 21700

The IQ3 is the first IQ to use a 21700 cell, and the change follows from everything else DaVinci changed. The IQ3's oven holds up to 0.7g, a third more than the IQC, and its Air Dial moves 70 percent more air through the load, which means the heater has to replace heat faster to hold temperature during a hard draw. A 21700 is 21mm across and 70mm long against an 18650's 18mm and 65mm, which gives it roughly a third more volume and, in DaVinci's cell, 4000mAh against the 18650's 3000mAh. That is where the IQ3's claimed 90 minutes of runtime comes from, and it is why the IQ3 needs its own glove and its own spares. The cost is that none of your IQ2 or IQC batteries carry over, and that 21700 spares are rarer on retailer shelves.

IQ3 21700 batteries

DaVinci sells two options. The single IQ3 21700 Battery is the cell the device ships with, a 3.7V, 15A, 4000mAh flat top for $29.95, and it was out of stock at DaVinci, Headshop.com and The Stash Shack when we checked. The one in stock is the DaVinci 21700 Battery Pack of 2 for $39.95: two VapeCell 21700s rated 4100mAh with a 70A maximum discharge, in a zipped carry case, cheaper per cell than the single. To The Cloud lists a higher-capacity 5000mAh 21700 for $24.99 which its listing positions against DaVinci's own cell rather than as one; more capacity is more runtime, but whichever you buy, choose an unprotected flat top, because a button-top or protected cell is longer and may not seat under the IQ3's door.

18650 batteries for the IQC, IQ2 and IQ Core

The DaVinci 18650 Battery is a 3.7V, 3000mAh flat top for $18.95, listed for the IQ, IQ2, IQ2 Carbon and IQC, and it is the same cell the IQ Core ships with. Smoke Cartel sells the identical certified cell for $18.95, which is worth knowing when DaVinci's own listing sells out; the 18650 2-pack for $26.95 was out of stock when we checked, as was To The Cloud's $19.99 cell. Any quality flat-top 18650 rated for at least 10A continuous will work; a protected cell is a few millimeters longer and will not fit under the door.

The spare matters most on the original IQ2, which our review found takes about six hours to charge over Micro USB; a second cell swapped in while the first charges is the only real fix. The IQC and IQ Core charge in about two hours over USB-C, so a spare there is a convenience, though anyone traveling with a vaporizer will still want one.

Warning: Carry spare 18650 and 21700 cells in a case, never loose in a pocket or bag. A key or coin across the terminals will short the cell, and a shorted lithium cell gets hot enough to burn. DaVinci's 2-packs include a case; buy a $3 plastic one for any single cell.

The 4-slot battery charger

Charging a spare inside the device means the device is out of action while it happens, so an external charger is the second half of the upgrade. DaVinci's 4 Slot Digital Battery Charger fits every size of DaVinci cell, 18350 through 21700, charges four at once, picks a current automatically or lets you set it between 0.1A and 1.5A, and shows each cell's progress on a screen. At $38.95 it was out of stock at DaVinci when we checked, and To The Cloud's older two-slot IQ External Charger at $29.99 was out of stock too. Neither does anything a reputable generic lithium-ion charger does not, so if you need one this week, buy any well-reviewed charger that lists 18650 and 21700, and treat DaVinci's as the tidy option for when it returns.

Cables

The IQ3, IQC, IQ Core and MIQRO-C all charge over USB-C. DaVinci's braided USB-A to USB-C cable is $11.99 and its USB-C to USB-C cable is $12.99; any decent cable works, but the braided one survives a bag. The original IQ2 is Micro USB and the IQ2 Carbon is USB-C.

Mouthpieces: Zirconia or Silicone

The mouthpiece is the part your lips touch and the last thing vapor passes before it reaches you, and it is also the cheapest part on this page. DaVinci makes each one in two materials and the choice changes flavor more than you would expect from a $6 to $11 part.

Why zirconia

Zirconia is the dense ceramic DaVinci uses for the whole vapor path on the IQ2, IQ3 and IQ Core. It is inert, so it adds no taste and holds none from the last bowl once wiped, and DaVinci rates it at ten times the strength of glass. The trade-off is that a ceramic mouthpiece warms over a long session at 420F and weighs more. The IQC ships with a mouthpiece made from a polymer DaVinci calls ShareSafe, which our IQC review found hygienic and unbreakable but listed among the device's few cons, because polymer softens the flavor and picks up a taste over time. Swapping it for the IQ2's zirconia mouthpiece is the best upgrade an IQC owner can make, and it costs less than a coffee.

IQ3 Zirconia Mouthpiece, $9.56

The IQ3 has its own flat mouthpiece, and it does not interchange with the IQ2's. It carries eight laser-drilled air holes with wider spacing than the IQ2 mouthpiece, which is part of how the IQ3 gets its extra airflow, and it comes with the silicone gasket that seals it to the top of the flavor chamber. Buy one as a spare or a clean swap for sharing. It is $9.56 at DaVinci and $9.99 at Headshop.com. To The Cloud's listing was $16.99, so skip it there.

Zirconia Flat Mouthpiece for the IQ2, IQC and IQ Core, from $5.99

DaVinci's IQ2 / IQ Core Zirconia Mouthpiece is listed for the IQ2, IQC and IQ Core and comes in a flat version for $8.95 and an extended one for $10.95. To The Cloud sells the flat zirconia mouthpiece for $5.99 with its rubber gasket, and its listing says the same thing our review did: this is the piece to pick up with an IQC because it tastes noticeably better than the polymer one. It is backward compatible with the original IQ as well. If you want a spare polymer mouthpiece instead, the IQ2 / IQC Flat Mouthpiece in silicone is $6.96 and is the sensible choice for a device that gets passed around a group, since it cannot chip.

Extended Zirconia Mouthpiece, $10.95

The extended mouthpiece is the same ceramic in a raised, tapered shape. As a mouthpiece it lengthens the vapor path and keeps your lips off the warm body during a long session, and its taper is a 10mm male joint, so it drops straight into any 10mm female water tool. It is the piece the IQ Core ships with as its 10mm zirconia water adapter, and the IQ2 shipped with a version of it, so IQ2 and Core owners already have one. IQC owners have the silicone version. DaVinci's extended zirconia mouthpiece is $10.95 as the second option on the mouthpiece listing.

The Flavor Chamber and the Cool Core

The flavor chamber is the part of a DaVinci that new owners understand least, and the part that the IQ3 changed most.

What the flavor chamber does

On the IQ2 and IQC the flavor chamber is a short zirconia tube with a silicone lid that sits inside the body between the oven and the mouthpiece. Vapor enters through the narrow passage at the top of the oven, passes through the chamber, and exits through the lid into the mouthpiece. It does three jobs. It is the vapor path, and because it comes out you can clean the whole path with a swab. It is a stash: DaVinci calls it a storage chamber, and it holds about one oven's worth of ground herb, so the next load rides inside the device. And, which is where the name comes from, you can fill it with something aromatic and vape through it.

Putting herb in the flavor chamber does not vaporize it; the chamber sits well above the oven and never gets hot enough. The warm vapor stream passes over whatever is in there and picks up its volatile oils, so dried mint adds a cool note, chamomile or lavender soften a harsh high-temperature draw, and a pinch of a fragrant strain lends its terpenes to a bland one. It is a mild effect and easy to overdo; a few pieces loosely packed beats a full chamber, which restricts the draw. Whatever you put in there collects the resin the vapor drops as it cools, so change it every few sessions and swab the chamber. Our reviews note two things in practice: the chamber can be fiddly to lift out with the pick tool, and a fine grind passes through the oven's holes and ends up inside it.

Tip: Grind medium for any DaVinci. Fine, dusty material passes through the oven holes into the flavor chamber and the mouthpiece, where it clogs the narrowest part of the path. Our grind guide explains how to get there with a normal grinder.

IQ3 Cool Core, $11.96

The IQ3's headline change is cooling. Its flavor chamber is longer, and inside it sits the Cool Core, a ribbed helix of glazed zirconia and glass that adds cooling surface along the path. Heat moves from the vapor into the ceramic, and DaVinci's figure is that vapor arrives 50 percent cooler than on previous models. The Core lifts out: run without it and the path is wider and the draw lighter, which some owners prefer for direct-lung hits through water; run with it and you get the cooling.

Tip: DaVinci's own trick is to put the Cool Core in the freezer for a few minutes before a session, which makes the first draws cold in a way no other portable manages. Dry it first if it has just been cleaned, because condensation in a cold ceramic tube drips.

The Core is also the part of the IQ3 most likely to need replacing, because resin builds on the ribs and a chip on a rib changes how it flows. One IQ3 ships with one Core; a spare is $11.96 at DaVinci and $11.99 at Headshop.com, cheap enough to keep one clean and one in use. The Stash Shack's $13.95 listing and To The Cloud's $16.99 one were worse value.

IQ3 Zirconia Flavor Chamber, $11.16

The IQ3's flavor chamber is its own part and does not fit the IQC or IQ2. It is sold without the Cool Core, which is why the two are separate listings, and the reason to buy one is the same as any chamber: a clean spare to swap in on cleaning day, or a replacement for one that chipped. To The Cloud makes the useful point that the chamber on its own, without the Core, is the configuration for owners who want the biggest volume and the least draw resistance. $11.16 at DaVinci, $11.99 at Headshop.com.

IQ2 / IQC Flavor Chamber with Silicone Lid, $9.96

For the IQ2 and IQC, DaVinci sells the Flavor Chamber with Silicone Lid for $9.96 and a plain IQ2 Flavor Chamber for $10.95; buy the one with the lid, because the lid is the part that perishes. To The Cloud has the same IQC and IQ2 chamber for $9.99. Two chambers suits anyone who uses the stash function or infuses, because a chamber that has held mint for a week tastes of mint for a while afterward. Note that the original IQ's flavor chamber is a different part, sold as the IQ Flavor Chamber for $10.95, and fits only the original IQ. The IQ Core uses the IQC's body and we expect it to take the IQC chamber, but DaVinci had not added the Core to the listing when we checked.

Dosage Pods: Preload, Measure, Keep the Oven Clean

DaVinci's dosage pods are the accessory that turns an IQ from a good vaporizer into a system, and they are the reason the IQ2 and IQC sit on our best vaporizers for microdosing list. If you have never used one, our guide to dosing capsules covers the general idea; this is how DaVinci's version works.

What a dosage pod is and why the IQ suits them

A dosage pod is a small perforated cylinder with a threaded cap, sized to drop into the oven in place of loose herb. Fill it, screw the cap on, and load the pod whole. Heat passes through the walls into the herb and vapor leaves through the perforations. When the session ends you lift the pod out with the pick tool and drop in a fresh one. Nothing loose touches the oven, so it stays clean for weeks, and because every pod holds the same amount you get the same dose every time, which is what makes pods valuable to medical users and to anyone tracking intake through the DaVinci app. The IQ oven is a plain cylinder with the pearl above it, so a pod sits in it as designed and the pearl screws down onto the cap to hold it. DaVinci's pods fit the IQ, IQC, IQ2 and IQ3; the IQ Core shares the IQC's oven and we expect them to fit, but DaVinci had not added the Core to the pod listing when we checked, so confirm before you buy six.

The trade-offs are small. A pod holds less than the bare oven, the walls add a layer for heat to cross so the first draw arrives a few seconds later, and a pod comes out hot, which is where a holder earns its place.

Tip: With a pod loaded, wait ten seconds after the device vibrates at temperature before the first draw. Our IQ2 review found the extra time lets heat soak through the pod wall, and the first draw is fuller for it.

Stainless Steel Dosage Pods, from $34.99

The IQ Series Stainless Steel Dosing Capsules are six threaded pods in 304 stainless, each holding up to 0.3g of flower, concentrate or both. Steel conducts heat better than ceramic, and DaVinci's figure is that the steel pods heat 16 percent faster than the ceramic ones. They are the pods our IQC review called fantastic, the ones the IQ2 Carbon shipped six of, and the ones the Dosage Grinder is built to fill. To The Cloud has the set for $34.99, DaVinci and Headshop.com for $36.95, and The Stash Shack's $34.95 listing was sold out.

Ceramic Dosage Pods, $24.95

The IQ Series Ceramic Dosage Pods hold 0.2g each and come six to a pack with a silicone carrying case for every pod. Ceramic heats more slowly and holds less, which makes these the pods for microdosers who want the 0.2g ceiling built in, and DaVinci's note is that they produce denser vapor when packed tight. The IQ2 shipped with one, so IQ2 owners know the size. They chip where the steel pods dent. At $24.95 they were out of stock at DaVinci when we checked, and no other store in our data had them, so treat this as a restock alert and buy the steel pods if you need pods this month.

The Dosage Pod Holder, from $25.99

Loose pods in a pocket shed herb dust, so the workflow needs a case. DaVinci's IQ Series Dosing Capsule Case is a brushed aluminum cylinder that holds six pods, with or without their silicone jackets, and the piece our IQ2 Carbon review singled out as satisfying to use: fill six pods on Sunday and the week's sessions are a twist away. At $25.99 it was out of stock at DaVinci. To The Cloud has the same Dosage Pod Holder in stock for $39.99, which is a steep premium but the only way to get one now. The $24 MIQRO version, covered below, holds a different pod size.

The Dosage Grinder, $59.96

The Dosage Grinder is a four-piece aluminum grinder with a ring in the bottom section that holds six empty pods under the teeth, so ground herb falls straight into them and all six fill in one go. Pull the ring out and it is an ordinary grinder. Our IQ2 Carbon review called the grinder, holder and steel pods together the most polished microdosing system we have seen from any manufacturer. It was out of stock at DaVinci at $59.96 and at The Stash Shack at $69.95 when we checked. The MIQRO Series Dosage Grinder does the same job for the smaller MIQRO pods and was in stock at $69.95 from DaVinci and $49.99 at Headshop.com, but its ring is sized for 0.15g MIQRO pods, not IQ pods.

MIQRO pods are a different size

The MIQRO and MIQRO-C oven is about half the size of an IQC oven, and their pods follow. The MIQRO Series Dosing Capsules are six stainless pods holding 0.15g each with six silicone cases, $24.95 at DaVinci and $24.99 at Headshop.com, and they do not fit an IQ, just as IQ pods do not fit a MIQRO. The MIQRO Series Dosing Capsule Holder is $24 and holds six, with a spare pick tool built into the lid. The MIQRO Series Extract Kit for $9.99 has discs and cotton sized for its pods. Own both a MIQRO-C and an IQ and you will be buying two of everything in this section.

Water Tools: 10mm Adapters, 14mm Glass and the Hydrotube

Every DaVinci portable is a 10mm device. The extended mouthpiece tapers to a 10mm male joint, and every water tool DaVinci makes or recommends has a 10mm female one. That makes the IQ family one of the easiest vaporizers to use with a water pipe, and it is the setting our IQC review called the most aggressive extraction the device can give. Our guide to dry herb vaping with a water pipe covers joint sizes and water levels; these are the DaVinci parts.

The 10mm adapter for each model

• IQ3. The IQ3 Zirconia 10mm Water Tool Adapter is the raised ceramic mouthpiece the IQ3 ships with. It fits any 10mm female joint and doubles as the extended mouthpiece. $11.16 at DaVinci, $11.99 at Headshop.com. The IQ2's adapter does not fit the IQ3.
• IQC, IQ2 and IQ Core. Two choices. The IQ2 / IQC 10mm Water Tool Adapter in silicone is $8.96 and is what the IQC ships with; it cannot break and flexes enough to forgive a joint that is not quite 10mm. The extended zirconia mouthpiece above is the ceramic version at $10.95 and what the IQ Core ships with. Ceramic tastes cleaner; silicone is the one for a bag.
• MIQRO and MIQRO-C. The MIQRO-C 10mm Water Tool Adapter in silicone is $8.76 and the MIQRO Zirconia 10mm Adapter, which is also the MIQRO's extended mouthpiece, is $9.95; Headshop.com has the zirconia one at the same price.

14mm and 18mm glass

Most bongs are 14mm or 18mm, and DaVinci does not make a step-up adapter, so the third-party market fills the gap. The Stash Shack's 3-in-1 Silicone Water Pipe Adapter for the DaVinci MIQRO and IQ is a stepped silicone sleeve that fits over the extended mouthpiece and seals into 10mm, 14mm and 18mm female joints for $8.99. It was the only DaVinci-specific item The Stash Shack had in stock when we checked, and it covers every piece of glass you are likely to own. To The Cloud's DaVinci Water Pipe Adapter is a ground glass reducer, 10mm female to 14mm male, for $13.99; it can break, but glass on glass seals better than silicone and tastes of nothing, and To The Cloud lists it for the IQC, IQ2, IQ3 and MIQRO. Buy the silicone one for a bag and the glass one for a desk.

Note: The IQ2 and IQ3 have an air dial; open it fully for water. The IQC and IQ Core have fixed airflow, and our IQC review still found a bubbler the strongest way to run the device, so expect a firmer draw rather than a poor one.

The DaVinci Hydrotube, $84.99

The Hydrotube is DaVinci's own bubbler, built around the way people actually use a portable. It is a tall, narrow borosilicate tube with a 10mm female joint at the base and a patented internal path that routes vapor up through the water and around an extended channel before it reaches the top, so the vapor gets water contact and a long path to shed heat. It is spill-resistant rather than spill-proof: tipped on its side, the water stays in the lower chamber, so it goes in a bag half full. DaVinci lists it for the IQ3, IQ2, IQ2 Carbon, IQC, IQ, MIQRO and MIQRO-C, the IQ Core fits through its 10mm adapter, and because the joint is a plain 10mm female it also takes a DynaVap M or any other 10mm device.

Our IQ2 review found it takes the heat out of long high-temperature draws and called it a little pricey at around $85, which it still is; our IQ2 Carbon review, which had one in the box, noted it makes the device top-heavy. It is for the owner who wants water cooling without a bong. It is $84.99 at DaVinci, $84.99 at Headshop.com and $84.99 at To The Cloud, so buy it wherever you are already ordering.

Warning: The Hydrotube weighs more than the device it sits on. Lift it off before you set an IQ down, because the weight up top tips the device over, and a fall onto the joint is how 10mm glass breaks.

Portable Glass Water Bubbler, $23.24

If $85 is too much for a bubbler, The Stash Shack's Portable Glass Water Bubbler for DynaVap and DaVinci IQ is the budget answer. It is under 3.5 inches tall with a 10mm female joint on the bottom, so the DaVinci's extended mouthpiece drops straight in. Fill it joint-down until the water sits above the intake holes; the store's guidance is that if you can taste water you have too much, and if there is no bubbling you have too little. It is not spill-resistant and not as cool as the Hydrotube, but it is $23.24 at The Stash Shack and $30.99 at Smoke Cartel, and it fits in a jacket pocket.

Concentrates: The Extract Kit and the Hot Knife

The IQ series is a dry herb vaporizer with concentrate support, not a dab device; our reviews of the IQ2 and IQC both call the concentrate experience gentle, and it will not replace an e-rig. Read our guide to vaping concentrates in a dry herb vaporizer for the general limits; these are the two DaVinci parts that make it work.

IQ Series Extract Refill Kit, $11.95

The DaVinci method for concentrates uses the dosage pod as a container. The IQ Series Extract Refill Kit gives you six porous ceramic discs and six organic cotton pads. Put a disc in the bottom of a pod, scrape a small amount of concentrate onto it, and fill the space above with a cotton pad or with ground herb, then load the pod as usual. The disc soaks up the melted concentrate and the cotton or herb stops it running, so the oven never sees it. The IQ3 ships with an extract kit and a stainless pod, and the IQ2 shipped with a disc, cotton and a ceramic pod; the IQC shipped with neither, so an IQC owner needs pods and this kit. It is listed for the IQC, IQ2 and IQ3 and priced at $11.95 at DaVinci and $11.99 at Headshop.com. Use a little concentrate; too much overwhelms the disc, runs into the oven when it liquefies, and is a job to clean.

DaVinci Hot Knife, $40

The Hot Knife is a USB-C electric dab tool with a glazed ceramic tip that reaches working temperature in about three seconds. Press and hold, touch the tip to the concentrate, and a measured amount lifts cleanly onto the disc without the scraping and waste of a cold tool, and without overheating it, since the tip is regulated. DaVinci built it for its EQ e-rig, but it is exactly the tool for loading a pod with a pea-sized dab, and it charges in twenty minutes for around fifty uses. It is $40 everywhere: DaVinci, Headshop.com and Smoke Cartel all stock it. It is a luxury for an owner who dabs occasionally and a time-saver for one who preloads pods with concentrate every week.

Half Loads: Spacers and the Pearl

Conduction vaporizers need a full oven. Herb that is not pressed against the hot walls does not extract, so a half-filled IQ gives thin vapor and wasted material. DaVinci's answer is two-stage: the pearl handles the first half, and spacers handle the rest.

IQ Series Zirconia Ceramic Spacers, $10.95

A spacer is a solid zirconia puck with a perforated top that sits in the bottom of the oven and takes up volume, so a smaller load still fills the space that is left and packs against the walls. DaVinci sells them as a set of two for $10.95, listed for the IQ, IQC, IQ2 and IQ3, and Headshop.com has the pair for $10.99. One spacer with the pearl screwed down takes an IQC oven that holds 0.5g down to a load well under 0.2g; two puts it near MIQRO territory. Older listings call these glass spacers, and The Stash Shack and Slick Vapes still carry a sold-out glass version; the current DaVinci part is zirconia, which is tougher and does the same job. Our IQC review's advice stands: between spacers and dosage pods for small loads, the pods win, because they shrink the load and keep the oven clean at the same time. Spacers are for the owner who wants small sessions without changing how they load.

Pearl and Gasket, $7.96

The pearl is the one part of an IQ that wears out. It is a zirconia ball on a threaded silicone post in the oven lid, and the gasket is the silicone ring that seals the lid against the body. Every adjustment twists the post, every session bakes the gasket, and after a year or two of daily use the post loses its grip or the gasket goes hard and the lid stops sealing. The symptoms are a pearl that wanders during a session, loose material in the battery bay, or a draw that suddenly feels leaky. Our IQ2 review noted that a pearl not seated squarely does not slot into the oven cleanly, and a tired post is usually why.

The IQ, IQ2, IQC, IQ Core Pearl and Gasket is $7.96 at DaVinci and $7.99 at Headshop.com. The IQ3 uses its own IQ3 Zirconia Pearl and Gasket, also $7.96 at DaVinci and the same at Headshop.com. The MIQRO-C has the MIQRO-C Pearl and Gasket for $7.96. Buy one with the device and put it in the drawer; it is the spare you will need eventually and the difference between a five-minute fix and a fortnight of waiting. To The Cloud's $16.99 IQ2 and IQC pearl is the same part at twice the price.

Tools and Cleaning

A DaVinci's parts all come out, so cleaning is a soak and a swab rather than a chore, and our complete cleaning guide covers the routine. Two DaVinci-specific notes from our reviews: the narrow passage between the oven and the flavor chamber is where resin collects, and a little isopropyl run through it clears it; and the flavor chamber can be stubborn to lift out, so patience beats force.

IQ Series Pick Tool, $10.36

Every IQ has a slim metal pick tool that slides into a slot in the body, for packing the oven, stirring a load, and lifting a hot pod or the flavor chamber. It is also the part that disappears, which is why every IQ ships with a spare and why DaVinci sells the IQ Series Pick Tool on its own for $10.36, listed for the IQ, IQC, IQ2 and IQ3. Headshop.com has it for the same price. The MIQRO's Pick Tool Pack is three shorter picks in a keychain sleeve for $9.95.

3-in-1 Vape Multi Tool, from $17.99

DaVinci's 3-in-1 Vape Multi Tool is a keyring tool with a brush at one end for the oven and flavor chamber, a flat end for packing the oven or a pod, and a pick for lifting pods and the chamber. It replaces the pick tool and the brush from the box, and it lives on a keyring for cleaning away from home. Headshop.com has it for $17.99 against DaVinci's $19.99. Headshop.com also sells a $12.99 IQ Accessory Kit with a chimney brush, alcohol wipes, a pair of o-rings and a spare mouthpiece gasket, which is a sensible drawer kit for an IQC or IQ2 owner.

Grinding: The Chewy G3

DaVinci sells the Chewy G3 alongside its own accessories, and for a conduction device that wants a consistent medium grind it makes sense. The G3 is a portable electric grinder that stores up to 5g in a hopper, grinds with five stainless blades at the press of a button, and dispenses through a trigger straight into an oven or a pod. It is the grinder our electronic grinder guide found actually works, and it suits a DaVinci because the oven is a plain cylinder a nozzle can fill without spilling. The Standard is $50.99 at Headshop.com and $59.40 at DaVinci; the Deluxe adds a cleaning brush, two filling cones and a stash tube for $101.99 at Headshop.com and $119 at DaVinci. If you fill pods, the Dosage Grinder is the better tool once it is back in stock; if you load the oven directly, this is the one.

Carry and Protection

Silicone Glove, $17

The IQ body is sandblasted aluminum, and it does not stay cool at the bottom during a long session, which every review of the range mentions. DaVinci's IQ2 / IQC / IQ Core Silicone Glove is a honeycomb sleeve that keeps the warmth off your fingers, adds grip, and takes the edge off a drop, for $17, and it fits the IQC, IQ2, IQ2 Carbon and IQ Core. The IQ3 Silicone Glove is a separate part for the IQ3's larger body, $17 and out of stock when we checked, and the MIQRO-C Glove is $15. A glove makes the device slightly wider, so check it still fits whatever case you carry it in.

Carrying Can, from $8.99

DaVinci's Dual Use Carrying Can is a small anodized aluminum cylinder with two compartments on a keychain, one sized for an 18350 battery and one for about a gram of herb. It was designed for the MIQRO, where a spare 18350 and a session's worth of herb ride on one keyring. For IQ owners it is a herb tin, because an 18650 will not fit. To The Cloud has it from $8.99, DaVinci for $11.96 and Headshop.com for $11.99, in five colors. For the device itself, DaVinci's Small Soft Case is $12.95 and fits the MIQRO-C; the larger IQ Soft Case was out of stock at $18. To The Cloud's leather sleeve by Zyyde is for the original IQ only and its listing says so, so IQ2, IQC, IQ Core and IQ3 owners should skip it.

Build Your Kit by Budget

Under $25, the essentials. A Pearl and Gasket ($7.96) for the drawer, a zirconia flat mouthpiece ($5.99) if you own an IQC, and the 3-in-1 Silicone Water Pipe Adapter ($8.99) for the glass you already own. IQ3 owners swap the mouthpiece for a spare Cool Core ($11.96). Nothing here changes how the device heats; all of it removes a reason to stop using it.

Around $70, the pod system. Stainless Steel Dosage Pods ($34.99), the Extract Refill Kit ($11.95) so the same pods run concentrates, and a second flavor chamber ($9.96) or IQ3 flavor chamber ($11.16) so one is always clean. Add the pod holder when DaVinci restocks it at $25.99, or pay To The Cloud's $39.99 now if you cannot wait.

Around $120, all-day power and water. An 18650 ($18.95) or the 21700 2-pack ($39.95), a generic four-slot charger or DaVinci's when it returns, the Portable Glass Water Bubbler ($23.24), and the Silicone Glove ($17). This is the setup that turns an IQC into a device that runs from breakfast to bed.

Around $250, the full DaVinci desk. The Hydrotube ($84.99), the Dosage Grinder ($59.96) when it is back, the Hot Knife ($40), the pods and extract kit above, and the Chewy G3 ($50.99) if you load the oven directly instead. It is roughly what the IQ2 Carbon shipped with, minus the carbon fiber.

What to Skip, or at Least Buy Last

• Batteries for the wrong model. An 18650 will not fit an IQ3 and a 21700 will not fit anything else. The 18350 is MIQRO only. Check the door before you order.
• The Dosage Pod Holder at To The Cloud's price, unless you need it now. DaVinci's own is $14 cheaper when it restocks, and a small pill case does the job in the meantime.
• The leather sleeve. It fits the original IQ only, and To The Cloud says so on the listing.
• Two grinders. The Dosage Grinder fills pods; the Chewy G3 fills ovens. Pick the way you load and buy that one.
• The Hot Knife if you do not dab. It is a good tool at $40, but it does nothing for a flower-only owner.
• A second Hydrotube-class bubbler. One water tool is plenty. If you own a bong, the $8.99 adapter beats a second piece of glass.
• The original IQ's flavor chamber. It is a different part from the IQ2 and IQC chamber and DaVinci lists it for the original IQ only. It is easy to add the wrong one to a cart.
• A glass adapter if you are clumsy. The silicone 3-in-1 does the same job and bounces.

What Comes in the Box and What to Add

Frequently Asked Questions

Can I use an 18650 battery in the DaVinci IQ3?

No. The IQ3 is built around a 21700, which is wider and longer than an 18650, and the bay is sized for it. DaVinci's own cell is a 3.7V, 15A, 4000mAh flat top, and any 21700 you buy should be an unprotected flat top so it seats under the door.

Do IQ2 accessories fit the IQC?

Almost all of them. DaVinci lists the mouthpieces, 10mm adapters, flavor chamber, pearl and gasket, 18650, dosage pods, extract kit, spacers and glove for both. The original IQ's flavor chamber is a different part, and IQ3 parts fit only the IQ3.

Which mouthpiece fits the IQ Core?

The IQ2 / IQ Core Zirconia Mouthpiece, in flat or extended form, which DaVinci lists for the IQ2, IQC and IQ Core. The extended version is the "10mm zirconia water adapter" the Core ships with. The IQ3's mouthpiece does not fit.

Do the IQ dosage pods fit the MIQRO-C?

No. The MIQRO oven is about half the size of an IQC's, and its pods hold 0.15g against the IQ's 0.2g ceramic and 0.3g steel. DaVinci sells a MIQRO Series pod, holder, grinder and extract kit, and none of them interchange with the IQ versions.

Do I need the Cool Core in the IQ3?

You need it for the cooling the IQ3 is sold on; without it the path is a plain flavor chamber, closer to an IQ2. It lifts out in a second, and some owners run without it for a wider draw through water. A spare is $11.96, because resin on the ribs is the main thing that changes how the IQ3 draws over time.

Is the Hydrotube worth $85?

If you want water cooling from a portable without a bong, yes. It fits every DaVinci, travels half full without leaking, and takes the heat out of a 420F draw. If you already own a 14mm bong, the $8.99 silicone adapter gets you most of the effect for a tenth of the price, and The Stash Shack's $23.24 bubbler is the middle path.

What size joint does a DaVinci water adapter have?

10mm male, on every extended mouthpiece and water tool adapter DaVinci makes for the IQ series and the MIQRO. It fits any 10mm female water tool directly and 14mm or 18mm glass through an adapter.

Why does herb end up in my mouthpiece?

The grind is too fine or the material too dry, so dust passes through the oven holes into the flavor chamber and the mouthpiece. Grind medium, keep the flavor chamber's lid seated, and if it keeps happening, load a dosage pod, which stops loose material leaving the oven at all.

The Bottom Line

Start with the spares that keep the device running: a pearl and gasket, a clean mouthpiece, and a second battery with somewhere to charge it. Then buy the one upgrade that matches how you use it. An IQC owner should buy the zirconia mouthpiece before anything else, because it fixes the one real flaw in a very good device. Anyone who wants consistent doses or a clean oven should buy the steel pods and the extract kit, and add the holder and grinder when DaVinci restocks them. Anyone who runs hot should buy a spare Cool Core on an IQ3 or a bubbler on anything else, and the Hydrotube is the best-made 10mm bubbler you can put on any of them.

None of it is required. A bare IQC with the parts in its box is a complete vaporizer, and the IQ3 ships with almost everything on this page already. The accessories here tune a DaVinci rather than fix it, and the best of them cost less than $12. Read the DaVinci vaporizers collection if you are still deciding which body to build on, and check our deals page before you order, because DaVinci's store had several of these parts marked down when we checked and Headshop.com was undercutting it on the Chewy G3 and the multi tool.
