Spigen, Ossia show off phone case with a battery that charges wirelessly OTA
Imagine a world where the battery in your phone charges wirelessly via over the air signals. Back in 2017, we told you that Disney was working on this technology. So is a company called Ossia. The latter today announced (via Gizmodo) that it is teaming up with smartphone case maker Spigen to produce a smartphone battery case that will work with Ossia's technology.

The Spigen Forever Sleeve case is a proof of concept and is on display at the Las Vegas Convention Center during CES. With Ossia's Cota wireless technology, once the battery inside a phone is dead, the one inside the case will take over the task of powering the device. This battery will charge without the use of any cords, pads or plugs even if it is meters away from the transmitter, and out of the line-of-sight. Even if the smartphone user is walking, as long as he is in the range of the 5.8GHz signals, the lithium ion battery inside the case will charge.

Both companies hope to bring the case to market by next year.
