Boundless CFX+

How do you turn the Boundless CFX+ on and change the temperature?

Hold both side buttons for three seconds and the device vibrates as it powers on or off. Preset mode offers four steps from 378F to 428F, while Precision mode sets any temperature in single degrees up to 430F. Session length, brightness and temperature units sit in the same menu.

Why does my CFX+ battery go flat when I have not been using it?

When the session timer expires the CFX+ drops to a Stand By screen rather than shutting down, which our review found flattens the battery if you walk away. Hold both buttons for three seconds to switch it off.

Can you use the Boundless CFX+ with a water pipe?

Yes. Boundless sells a CFX+ water pipe adapter that replaces the mouthpiece. It arrived after launch, so earlier owners may recall no official option, and third party versions are rare.

Can you put concentrates in the CFX+?

Boundless does not sell a concentrate pod for the CFX+, and its warranty excludes damage from loading wax or oils without one. Melted concentrate running through the bottom of the ceramic chamber is close to impossible to clean.

How much herb does the CFX+ chamber hold?

Around 0.3 to 0.5 grams, a lot for a portable this size. Airflow is restrictive, so packing firmly to the top makes the draw harder rather than the vapor thicker. Boundless sells a dry herb pod that drops into the chamber to keep residue off the ceramic.

How long does the CFX+ last on a charge?

Our review found at least an hour of use per charge, more at lower temperatures. Boundless puts the USB-C recharge at under an hour, though a weak adapter can stretch that to two.

What warranty does the Boundless CFX+ come with?

The CFX+ manual states a three year limited warranty from the date of retail purchase, and Boundless honors three years on any device whose packaging says so. Its general site policy is one year, so keep the receipt and the code printed on the box.
