It does exactly what it says on the tin. Allows you to use your Minigorilla to charge your iPad without any problems. As with most Powertraveller products it is well made and constructed and sould last for many years. Recommended if you have a Minigorilla and a iPad and need extra juice when out and about.
Used the USB adaptor for 2 to 3 months and worked great. Charged both my ipad and other phones using the 2.1 Amp and 1.0 amp output. What I liked about it was that it was not too large to obstruct and not so small that you struggle to get the adaptor out. Unfortunately the adaptor plastic between the two USB sockets snapped and the small metal divider popped out; this meant that it would no longer hold a USB plug in place. Returned to amazon with no problems under warranty. In summary: Good idea, good power output, poor material for USB socket.
