This blog post is intended to educate the reader on the best possible strategy for charging these internal battery devices to maintain battery health and avoid any problems when charging a device .

It is important to remember that the batteries used in vapes do not have a memory, this means you can charge them for 10 or 100 minutes without affecting the overall health of the battery. What does affect the health of the battery (and can cause some problems) is how quickly the battery charges. When a battery is charging quickly it is either due to a high voltage (v) or ampere  limit on the charger (a).

Although charging batteries quickly is a desirable outcome, issues can arise if the battery becomes too hot and loses its ability to cool itself down. This is called thermal runaway.
Thermal runaway is when the chemicals in the battery get so hot, they continue to react with each other, even when they have had safeties and limiters put in place. As the chemicals continue to react, heat and pressure builds up inside the battery and results in an explosion. This can happen very quickly and is impossible to predict when it may happen in real life conditions, since the results are disastrous, thermal runaway should be avoided at all costs.

- If your device gets uncomfortably warm (hard to describe how warm is too warm, so err on the side of caution, if its warmer than body temp) take it off the charger till it cools.

Some modern phones have fast chargers. These chargers are designed to have an incredibly high voltage or ampere limit to facilitate the fast charge function that fancy new phones benefit from. The batteries in Vapes are not designed to be used with the chargers and do not share the same protections for the battery.

Every charger should have an Output and input written on the side of it. If the output is greater than 5v or 2a it may not be suitable for charging vapes. See below for an example of an output for a huawei power bank.

- Check the outputs of the charging ports prior to use to ensure they are LESS than 5v and 2a.

Although it can still  technically work and charge vapes, there is the potential for explosion due to thermal runaway. Hoopers Vapour does not recommend using these to charge vapes, but if you do, then it is highly recommended to supervise the device while it charges and make sure it does not get hot to touch. 

If you have a newer vape with a USB C port you do have a bit more freedom with what you can and cannot plug into. But it is important to check both the plug specifications and the device prior to plugging the vape in. 

Some vapes have overcharge protection, which is an important tool for maintaining battery health and avoiding thermal runaway. Hoopers Vapour does not recommend using Type C charging unless you are aware of the power output of the charger and whether there is overcharge protection on the device.

- Check whether your device has overcharge protection.

It is not recommended to leave batteries or devices on charge overnight. If the over charge protection fails you have a potential fire risk when you are most vulnerable. Hoopers Vapour does not recommend overnight charging under any conditions and at the end of the day we cut a lap of the stores to ensure no devices or batteries are left on charge.

- Don't charge overnight.

Golden Rules:
- Check whether your device has overcharge protection.
- Check the outputs of the charging ports prior to use to ensure they are LESS than 5v and 2a.

- If your battery gets too hot to touch, take it off the charger till it cools.
- supervise, or remain close to devices while they charge.
- Don’t leave things to charge overnight.
