When you leave the house, your phone is as essential as your wallet or your keys. That’s why it’s so annoying when it isn’t charged, and you have to plug it in and wait for what seems like forever.
Fast charging solves that. Here we’ll explore what it is, how it works and which phones boast it as a feature. You’ll never be kept waiting again…
What is fast charging?
As the name suggests, it’s a way of charging up an electronic gadget like a phone or tablet that’s much quicker than standard charging.
How much faster is it?
Much. Some phones can charge from a flat battery to 50 per cent juice in just 15 minutes.
How does fast charging work?
It basically provides the phone’s battery with more power. Most fast chargers dynamically vary the voltage (the strength of the electric current), but some amp up the amperage (the amount of electricity flowing from the battery to the connected device, also known as current). Most phones usually handle 5V/2.4A, but fast chargers bump the voltage up to 9V, 12V or beyond, or increase the amperage to 3A or more.
Are there different standards of fast charging?
There are. The main ones are Qualcomm Quick Charge, Samsung Adaptive Fast Charging, Huawei SuperCharge and MediaTek Pump Express.
Do I need a compatible charger?
You do. You also need a compatible cable linking it to the phone, and a handset that’s enabled for fast charging. Stick to the charger that came in the box, and you should be fine.
