Electronic cigarettes with 20700 battery

1x20700

— powered by one replaceable 20700 battery.

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 such a power supply, it is even possible to install 18650 batteries. As for the quantity, relatively low-power battery mods, up to 100 watts, are equipped with one 20700 battery.
