must have accessory if you vape a lot at home & hate charging & changing the batteries.
One end plugs in to any USB socket & the other screws onto the Joye 510 Atomizer/Cartridge. You can vape endlessly connected or disconnect and use the inline battery (included) which lasts about 3 times as long as a standard 510 battery!
The inline battery charges anytime the USB is connected so you can vape while you charge & charge while you vape.
