Dr. Dabber Boost Evo

Concentrate goes straight onto the bottom heating plate of the Boost Evo's quartz eChamber, so oil pools in the dish and creeps toward the magnetic contacts holding the chamber to the base. Above that, the quick connect adapter and the quartz to glass pathway collect condensate, and water from an overfilled glass attachment runs back down into the chamber.

1. Swab the eChamber after every session: Dr. Dabber's advice is to mop leftover residue out with a dry cotton swab, then, while the quartz is still warm, use a swab dipped in isopropyl on any stubborn marks. Warm residue lifts far more easily than residue left to harden. Darkening of the quartz, called chazzing, is normal and does not hurt flavor or function.

2. Wipe, do not soak: the manual permits up to 91 percent isopropyl on the atomizer and the glass, and up to 75 percent on the Boost Evo body and the quick connect adapter, but it is explicit that the atomizer, adapter and unit must never be fully submerged. Dry burning an empty eChamber is also out. Dr. Dabber asks for a small amount of oil in the dish whenever it heats.

3. Strip the top down: the eChamber is held magnetically, so pull it straight up to lift it clear. Remove the glass attachment and quick connect adapter too, then clean residue in and around the chamber seat, the adapter and the loading tool with a swab or paper towel dipped in isopropyl. Let everything air dry fully.

4. Shake the glass clean: fill the water attachment with isopropyl, shake hard until the marks lift, repeat if needed, then rinse thoroughly with water and air dry. Refill with water only just above the perc holes, since overfilling causes splashback into the eChamber. If you run a TDE attachment or carb cap, swap the adapter's standard silicone seal for the TDE seal packed with the glass, or the cap will not seal properly.

5. Keep the electrodes clean: white, pink or orange triple blinks usually point at a dirty connection rather than a dead chamber. Swab the contacts on both the eChamber and the base with isopropyl. After fitting a fresh eChamber the unit needs recalibrating: leave it off and unplugged for fifteen minutes so both parts sit at room temperature, then click the button four times, holding on the fourth until the lights flash white.

The eChamber is a consumable, typically good for four to twelve months, and is excluded from the one year warranty. Replace it when the dish cracks, leaks or tastes burnt after a proper clean. For the battery, charge once it drops to a single LED and unplug at full.
