How does wireless charging work?

Wireless chargers work by creating a small electromagnetic field.

This is created by a coil in the charger and is received by another coil inside a compatible phone. The phone then converts this electromagnetic energy into battery power.

Can I use any wireless charger?

Most phones use a QI charger (pronounced chi), which is the most common wireless charging technology.

There are other types of wireless charging technology available, so it's important to check what your phone is compatible with.

Other technology available includes AirFual and PMA, which are sometimes available in public places.

Generally speaking, the more wattage, the faster the charge. However, this does differ between phone models. iPhones charge faster up to 50%, but are slower to charge up to 100%.

Is wireless charging safe?

Phones do get hotter when they charge. But there's minimal risk of overheating, unless the battery is faulty.

You may need to take off your phone case

Wireless chargers only create a small magnetic field. It may not transmit through a thick case and can't pass through metal.

Portable power banks

These portable batteries are great for charging your phone when you're away from home.

The higher the power bank capacity, the more charge your phone will get. A 2000mAh power bank, will give you a small power boost, while a bank of over 10,000mAh would charge your phone around 4 times.
