Qi Wireless Charging Extends Range and Power

Qi a wireless charging standard created by the Wireless Power Consortium (WPC) says later this year its standard, adopted by over 200 manufacturers and carriers, will allow you to charge your device from nearly two inches away.

Mobile device manufacturers using the Qi standard include Asus, HTC, Huawei, LG Electronics, Motorola Mobility, Nokia, Samsung, BlackBerry, and Sony.

Inductive charging does not require you to plug your device in to charge. A charging pad under your device provides charging current wirelessly.

Now Qi is adding new functionality that will allow you to charge your device from nearly two inches away through “resonance charging“.

With version 1.2, the receiver and the transmitter now won’t need to physically touch each other. They can be up to 45mm (1.77 inches) apart. The new standard is backwards-compatible, so if you already have a smartphone or tablet with Qi built-in, you’ll be able to charge them up from as much as 35mm away.

The standard also allows multiple devices to charge up at the same time, provided they’re both within range, and it will be capable of pushing as much as 2,000 watts to larger products like kitchen appliances.

Two competing wireless charging standards, Rezence (WiPower) and the Power Matters Alliance, already have adopted resonance charging, but the WPC claims that Qi is more power efficient and has a larger group of partners and products.

Mobile device manufacturers using the Qi standard include Asus, HTC, Huawei, LG Electronics, Motorola Mobility, Nokia, Samsung, BlackBerry, and Sony.
