When it doesn't deliver the promised 300 amp hours (300000 mAh), I'll
sue WalMart and then buy me a new ASH-31 mi.

If it is not a constant load then some of the "external power packs" may shut themselves off when they see no load. I don't know about the Oudie, but I've had such problems with other devices. Those battery packs that you have to start with a button push (the vast majority) are the ones to avoid. There are a few models that either have an on/off slide switch, or sense the load and automatically turn themselves on.
