Can't figure out why I still get "sorry no matches" no matter what search terms I use. I read the Q&A which says that you can't charge "most android tablets" from the USB port, but I don't really own "most tablets." I just own one, and can't believe that charging from the USB port isn't possible. Did I make a mistake buying this device, since I now have to carry around a dedicated charger? What chargers will work other than the one that the device came with? Anything with the same mini pin that hav 5V output? Anything over 1 watt or is the 2.5 a must? What happens if you plug it in to an Amazon Kindle or a iPod usb/wall charger? You'd think this would be covered somewhere in the documentation, but I sure can't find it. BTW, I posted this question before but can't seem to find it and I assumed that I'd automatically be subscribed to a thread I started, but I guess not.
