Big things come in small packages, and the Standard Series Battery is no exception! Stylish and discreet, this battery can hold its own in both private and public use, and its sleek design maintains a low profile whether in use or stowed away. This 510 thread vape is compatible with any pre-filled oil cartridge, wax attachment, or other 510 accessory you want to use. It heats at a steady 3.7V each and every session.
