All I want is a source generating enough power for the tablet to have infinite standby time. That would make it practical to use as a fridge computer, and I'd buy an N800 for this purpose right away.

I don't mind charging the device when I've been using it, but charging it every couple of days whether or not I've used it ... that just sucks.

Solar, even indoors in a kitchen, should be capable of generating enough power for this.

Regards,
Roger
