These are rechargeable lithium ion batteries. The same standard 18650 that has powered laptops, EVs, and power banks.

They're packaged inside a single use product, but the battery is rechargeable.

Many products actually have charging ports now. All they need to do is allow users to change out the flavor wick and we will come full circle.

Yeah, some extra electronics to handle charging would go a long way.

Buuut, Quality charging controllers cost money the vapes company isn't going to put in, and overly cheap controllers add a bigger fire hazard.

Not an 18650, that’s way too big (18x65mm). Smaller than 14500 (AA) for sure
