Some of the latest USB chargers, however, offer fast charging with 10 watts of power.

The Wireless Power Consortium is already working to extend its Qi specification to allow 10 watt power charging, said Menno Treffers, chairman of WPC.

"In the U.S., you're seeing smartphones [with wireless charging] taking off this quarter," Treffers said. "Europe will be a little later than the U.S."

In Japan, where the wireless charging market is more mature, several companies have put out combination products, where a single system can be used to charge a device while transferring data.

For example, TDK a Bluetooth enabled speaker that also uses magnetic induction to power mobile phones while also playing music stored on them.
