Electronic cigarettes with 18650 battery

1x18650

— powered by one replaceable 18650 battery.

For general features of replaceable batteries, see Battery section. Specifically, 18650 is the most popular size used in modern vapes (and one of the most common in general). Such batteries have a diameter of 18 mm and a length of 65 mm; in terms of capacity and power, they are somewhat inferior to larger cells like 26650, but these characteristics are still sufficient for most cases. In terms of quantity, one 18650 cell is used in relatively low-power battery mods — up to 100W.
