They usually consist of two sections, basically a tank and a separate battery. Their batteries have higher capacity, and are not removable. Being rechargeable, they use a USB charger that attaches to the battery with a threaded connector. Some batteries have a "passthrough" feature so they can be used even while they are charging.]
E-Cigarettes commonly use a Tank or a "Clearomizer".

Clearomizer, Tanks are meant to be refilled with e-juice, while cartomizers are not. Because they're refillable and the battery is rechargeable, their cost of operation is lower. Hovever, they can also use cartomizers, which are pre-filled only.Some cheaper battery sections use a microphone that detects the turbulence of the air passing through to activate the device when the user inhales. Other batteries like the eGo style can use an integrated circuit, as well as a button for manual activation. The LED shows battery status. The power button can also switch off the battery so it is not activated accidentally.
