PRO Folding Blade Charger Works for Nvidia Shield with Durable 5Ft/ 2M MicroUSB Cable!

This power supply is for a USB device - it is not the 19v 2.1A 40W power supply for the Shield TV and Shield Pro. You have to contact Nvidia for a replacement if it is under warranty or buy it on eBay if you can find one. It is a proprietary adapter and Nvidia does not sell a replacement.
