Was looking at the Bose, but I checked the battery life. I am one of those people that need not "up to 10 hrs" but closer to 18. I use mine a lot with no facility to charge. Sorry.
Do you have any assembled "space heater" type boxen? Ones where the compute is not great, but would help keep the chill off in a room? Also, if you are turning out assembled boxen, are you putting an O/S on them? Maybe a Linux that has a GUI option.
