The stylish Jane West 510 threaded battery is compatible with most 510 thread cartridges and features a variable voltage dial, a power button in the center, and our signature sun icon to identify your Day cartridge of choice.
After screwing in your 510 thread attachments, turn the battery on using a power button and adjust the dial on the battery base to select your desired temperature. The Jane West battery includes a geometrically shaped USB charger base that is perfectly handy when the battery requires a power boost.
