I used to have roommates who vaped from that exact type of single-use device shown in the thumbnail diagram. They asked me to re-charge it, which I did, disassemble it, connect it to my Li-ion charger and it worked again. Apparently it didn't taste good because it was nearly out of juice, but that was when I found out these were perfectly reusable 3.7V batteries in a disposable product.

    Isn't there a difference between rechargable and single-use-batteries? I was always under the Impression you should under no circumstances try to recharge single use batteries or they would explode?

    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.

    You'd need quite a number of alkaline batteries to get the necessary watts to drive a vape. Lithium cells aren't just rechargable they are also good at releasing lots of energy in a short amount of time.

    There is a difference. Not sure how they ar made, but the chemical composition and possibly the design is different.

    Trying to recharge a non rechargeable battery can risky and there is the possibility of leaking or explosion.

    In general yes, but that doesn't apply here. Vapes all use rechargeable lithium batteries, even the disposables without a charging port. Other battery chemistries at that size don't put out enough power.
