The Convertible Battery is unique in that you can use it in multiple ways. At the top of the battery, there are two connections. The very top part (The Halo) with the glass mouthpiece, is held on by magnets. When opened, the consumer can place a dab in the cup with the quartz heating coil. The other way to use it is to unscrew the second top piece and substitute it with a universal 510 Cartridge and use it as a normal cartridge pen. This battery is button activated and has three variable temperature settings for the consumers comfort. You can customize it by adding your brand logo in one color and the body color can also be changed out to fit your needs. Custom Packaging is also available upon request. First in its class, the Convertible is paving the way for high quality vaping in multiple ways with one pen.
