What is Qi wireless charging?
Qi wireless charging is a global standard to which many smartphones adhere. It allows you to wirelessly charge a compatible device's battery using induction transfer, simply by placing it on top of a wireless pad - and with no need for cables or adaptors (other than to the wireless charger itself).
Inductive charging (also known as wireless charging) uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device.
The EC Technology Ultra-Slim Wireless Charger and devices like it emit non-ionizing radiation, which is not harmful to humans.The device will become warm in use, but it will not exceed 40ºC.
If a smartphone supports Qi wireless charging then any Qi wireless charger will be compatible with it - not just that which is sold as an official accessory for the phone. This means you can often save some money on a third-party brand charger, as is the case with EC Technology's Ultra-Slim Wireless Charger.
Wireless charging is typically slower than traditional charging. This EC Technology Qi charger delivers a 1A current. That's pretty standard, and fine for a smartphone, but you'll notice the difference with tablets such as the Nexus 7 - these will charge much faster using a 2A charger.
The low-power Qi wireless charging specification is able to deliver up to 5W of power; medium-power Qi will offer up to 120W.Low-power Qi is said to be able to travel up to 4cm. With the EC Technology Ultra-Slim Wireless Charger we found our Nokia Lumia 735 would still charge when held up to 2cm above the pad. Obviously this isn't comfortable or practical, but it's interesting to note the two devices don't need to be in direct contact with each other.
