How Long Does It Take For Electronic Cigarettes To Charge?

Electronic cigarettes have become increasingly popular over the last decade.

Commonly, a new vaper will purchase a starter kit that will include a rechargeable battery, which is how electronic cigarettes are powered. A frequently asked question is how long will it take to charge? There is no fixed answer to this question as it all depends both on the e cig brand and the size of the battery, however a common answer is two to four hours although it is possible this could be up to eight hours.

Normally the batteries included in the electronic cigarette’s starter kits are NiMH – a nickel-metal hydride battery to be precise whose energy density approaches that of a lithiumion cell. The size of the battery is then shown by something called mAH. This stands for milli Amp Hour and this rating is a measure of the capacity of the battery. A good rule of thumb is that the bigger this mAH number is, then the longer the battery will last – this is not the case when comparing batteries of different chemistry and use as the higher capacity is not necessary the best, but in the case of comparing the sizes of the batteries in the different starter packs for the e-cigs as they are all of a similar type, then this is quite accurate.

The mAH number can also be quite useful when considering how long the life of the battery will be – for instance a 90mAH battery probably would not stretch to an hour, while a 360mAH one is likely to last over three. A typical size included in a starter pack is 900mAH and this should last at least eight hours.

It is also worth remembering that the larger a battery is in terms of mAH and hence the longer it will last, then the longer it will probably take to charge. Several starter kits helpfully include two batteries (probably one with a lower mAH than the other) so that one can be charged while the other is in use and some batteries are even of the pass through nature allowing the user to carry on vaping while the battery is still charging!
