Wireless charging

Wireless charging

Technology for inductive charging of a battery

Wireless charging (also: wireless, inductive charging or wireless charging as well as Qi charging) is a technology for charging a smartphone battery without the use of a cable.

For inductive charging, users need a special charging pad or a charging pillow. The proprietary standard called “Qi” has become widely accepted. Chargers are available with different charging powers of 5 W, 7.5 W and 15 W.

Advantages of inductive charging

Devices and charging pads from different manufacturers are compatible with each other when using the same standard, which means that an iPhone also charges on a Samsung charger, for example.

Signs of use, such as dirty charging plugs and wear and tear on plug contacts, are no longer a problem – it’s enough to simply place the mobile device on the charger. It is sufficient to place the mobile device on the Qi pad. Charger is always ready at a strategic place (desk, nightstand …) and does not have to be connected via cable first.

Disadvantages of inductive charging

Due to the lower efficiency, more power is consumed for full charging. Also, wireless charging can reduce the charging speed compared to wired charging.
