Quick answer: Every disposable and pod kit runs on a lithium-ion battery, and most problems come from heat, damage or the wrong charger. Charge only with a proper cable and a standard phone-style USB adapter, on a hard surface where you can see it, and unplug when full. Keep devices out of hot cars, direct sun and pockets with keys or coins. Stop using any device that gets hot, swells, leaks, hisses or smells, and never charge a disposable that isn't made to be recharged.

Want a device built to recharge?

Rechargeable disposables have a USB-C port and a battery made for it.

Charging the right way

Use a USB-C cable in good condition and a standard 5-volt phone-type adapter.
Avoid fast chargers and high-watt laptop bricks unless the maker allows them.
Charge on a hard surface, not a bed or couch, and stay nearby.
Unplug when the light shows full.
Never charge a disposable that has no charging port.

Step by step: how to charge a disposable vape.

Heat and cold

Situation	Risk	What to do
Hot car or direct sun	Battery overheating, leaks	Carry it with you; never leave it in a parked car
Freezing cold	Weak hits, slow charging	Let it reach room temperature before use or charging
Pocket with keys or coins	Short circuit on exposed contacts	Keep it in its own pocket or case

Warning signs: stop using it

The device gets hot in your hand.
The body swells or splits.
It hisses, crackles or smells like burning plastic.
Liquid leaks from the charging port.
It keeps firing on its own.

Put it on a non-flammable surface away from anything that can burn, let it cool, and take it to household hazardous waste: how to dispose of a disposable vape.

Using a pod kit or mod?

Use the coils and batteries made for your device.

Shop vape kits, pods and coils

Water and drops

Water in the charging port or a hard drop can damage the battery. Don't charge a wet or cracked device. If it was dropped and now gets warm or acts strangely, stop using it.

Storage

Store devices at room temperature, out of sun, away from children and pets, and not loose with metal objects. More: how to store your disposable vape.

Travel

Vapes and spare lithium batteries travel in carry-on bags only and can't be used or charged on a plane. Keep spare batteries in a case so the ends can't touch metal.

Pod kits, mods and spare batteries

Use the battery and coils your device is made for.
Carry spare 18650-type batteries in a plastic case, never loose.
Replace batteries with torn wraps or dents.
Match coils to the wattage range printed on them: coil resistance and wattage chart.
