Nokia is live at its "41 Million Reasons" event in New York City, where the company just unveiled the Nokia Lumia 1020 and a seperate charging accessory. 

The Nokia Lumia 1020 doesn't have wireless charging, but it will have a charging shell accessory that can provide extra battery life.Nokia showcased a built-in battery accessory called the Camera Grip.

The Camera Grip is a snap-on cover that offers one-handed shooting and two-step shutter control button. It also has a tripod mount - and, as mentioned before, a battery built into the shell. It'll attach to the rear of the Lumia 1020 and sports a USB port.
