Most portable vaporizers are powered by either an internal rechargeable battery, which can be charged using a normal AC power adapter. The classic example of these are the Arizer Solo and Vapir NO2 Vaporizers. However certain personal vapes require the user to press a special NiMH (Nickel-Metal Hybrid) AA battery into the device to activate a convection current. The Magic Flight Launch Box, Palm, and Palm 2.0 Vaporizers are the two lines of portable vape that employ this battery method. If you need a replacement battery for your handheld vape, Vaporizer Depot has the internal or external battery for you.
