Up to 45mm

The Wireless Power Consortium has detailed its new upcoming Qi v1.2 wireless charging standard which will bring improvements in the charging distance supported by Qi-enabled devices.

While current Qi standard is a neat thing, but it only allows a charging distance of 7mm and the new Qi v1.2 will greatly improve that by promising an increase to 45mm. According to the consortium, five member companies have already demonstrated charging at 45mm distance with prototype receivers.

The WPC also noted that while Qi chargers have always been capable of multiple-device charging, the new standard, which will enable the use of single inverter for multiple coils, should also bring cheaper charging stations.

The Wireless Power Consortium also noted that the new Qi standard provide wireless power of up to 2000W for kitchen applications, which sounds like a really neat idea for many kitchen appliances.

The new Qi v1.2 standard will be backwards compatible with the Qi v1.1 and will allow current smartphones to draw power from new Qi v1.2 stations from a distance of up to 30mm.
