Electronic cigarettes with two 20700 batteries

2x20700

— powered by two replaceable 20700 batteries.

For general features of replaceable batteries, see Battery section. And the 20700 cells are somewhat larger than the popular 18650 batteries — the length is 70 mm (against 65 mm), the diameter is 20 mm (against 18 mm). At the same time, these elements do not have key advantages over the same 18650, so they are much less common; and in some mods with this power supply, it is even possible to install 18650 batteries. As for the quantity, using two cells of the 20700 type allows you to reach a power of more than 220W, and in some models even more than 300W.
