The clever ergonomic design of the Cloak battery “Cloaks” or hides your vaping cartridges, while simultaneously protecting them. Providing a stealth vaping experience, it enables you to carry it wherever you go and use inconspicuously in any environment. Not to mention, it has an ingenious, sleek design that is as stylish as it is concealing! The Cloak battery can be used with a half or full gram capacity cartridge and is extremely easy to load and use. With a button-free technology, all you have to do is draw in to switch it on. Moreover, it has carb holes at the bottom, which can be easily covered with a finger as you begin to draw or left exposed to regulate the amount of air flow, depending on whether you want a small or big hit. While the battery can function with any standard 510 thread cartridge, it’d be best to use it with CCELL® cartridges as it’s designed to work best with the latter. It’s rechargeable with any micro-USB port – a USB charger is included.
