How Fast Charging Works?

Chances are that you don't give more than a few seconds of thought each day to charge your phone, hopefully, you remember to do it before you go to bed and that's about it right or what if you just woke up then realizing you forgot to plug it in your battery bank is somewhere and you have to leave the house in half an hour.

Enters fast charging feature which is supported by some modern phones and tablets, then you power it up in the time that it takes that'll rinse the only shower, grab a cereal bar and get your shoes on, it's either reason  many devices take such a long time to charge normally is the limited amount of power many common wall chargers can push to your phone or tablet at once, typically five watts or less this is a design choice that keeps manufacturing costs for basic wall warts low and also ensures that the relatively small batteries inside of mobile gadgets won't fry from being overloaded with too much power.

But in reality many mobile devices can handle more than this thanks to internal circuitry that sets a maximum amount of wattage that will hit your battery at one time, fast chargers take advantage of that by adjusting the voltage amperage or both to deliver up to 20 watts or even higher if your device supports the technology, whoa whoa whoa hold on a second loop supported technology what needs to be supported we're just clobbering a battery with electrons, well there are a lot of factors but one of the most basic ones is that with higher power comes higher heat so a device without enough internal room for the battery to expand  might end up damaged if it gets charged too quickly, so for that reason many companies that developed fast charging technology have implemented a handshaking process between the charger and phone or tablet to make sure they're both certified to support the extra power.

Samsung's fast charge and Onepluse`s Dash charge are both popular protocols but perhaps the most widespread one is Qualcomm quick charge which is found in a large number of Android devices, so this means that just because the charger says it supports 2.5 amps at 5 volts doesn't necessarily mean that it will  charge your phone superfast and there are other cautions as well,  although many devices that support fast charging do come with compatible chargers you'll pay a premium for extra ones and you might need to buy slightly nicer cables too as cheap thin 28 gauge cords often can't handle the extra current very well, also remember that as we mentioned fast charging can generate more heat which is harder on your battery and may shorten its longevity a real concern now that so many phones are very difficult to open if you want to put in a new one, plus fast charging is much more useful when your battery  is significantly drained and you need a really quick partial charge to keep you afloat for a little while speeds tend taper off significantly as your phone gets closer to 100% so unlike filling up at a fast pump gas station for the big gears don't expect to go from empty to full with blazing speeds though at least you won't have to pay 50 bucks every time you need a recharge or more.
