Best Vape Battery Chargers 2018 - vape chargers for 18650 & 21700 cells

Best Vape Battery Chargers

Because we don't generally recommend charging your batteries inside the mod, these are our top picks for Best Vape Battery Charger. This is particularly important in the case of box mods powered by dual 18650, 26650, 20700 or 21700 cells.

Most chipsets don't offer balanced charging, which means that one of the cells is likely to receive more volts than the other. This has a dramatic effect on the lifespan of the battery and can induce preventable, premature wear.

Using an external vape charger will ensure your batteries always receive the correct voltage. This prevents overcharging and helps keep the cells' health to 100% for even more cycles.

With more advanced vape battery chargers you can even read the status of the cell, adjust the amps automatically and show detailed info about various parameters.

More about external battery chargers

If you don't want to replace your vape batteries once every few months, we recommend using an external charger. These units are not as expensive as you might think and they can save a lot of money on the long term.

Whether we're talking about 18650 battery chargers, or units that are compatible with more than one type of cell, these devices are very important. As opposed to charging your batteries inside the vape via USB cable, external chargers offer three key advantages. They allow for much safer charging, the process is faster and most importantly: it's more accurate.

Vape battery charger parts

In order to extend the lifespan of your vape, the batteries must not be charged over 4.2V. Most box mods try to prevent this from happening, however they are not very accurate.

Some devices will charge the batteries to 4.22V, others to 4.25V and the list can go on. This may not seem like much, but unfortunately it has a negative impact on the number of charging cycles a cell can withstand and its overall performance.

It doesn't really matter if you use recommended mod batteries or generic brands, the chemistry behind the charging process is the same. And this process is always more reliable with an external charger. Even a cheap vape battery charger that sells of $16 is a big step up from charging the batteries inside the device.

These units have built-in algorithms that adjust charging speeds according to the current voltage of the battery and can even bring "dead" cells back to life. A cell is considered "dead" when its internal voltage has dropped below 2.8V.

External vape chargers can deliver from 0.5A up to 2.0A to each cell, greatly improving charge speeds while at the same time preventing the batteries from overheating.
