Duracell DPP-600HD Perfect for C-Pap during power outages

I was looking for something to power my C-Pap when the power runs out, but didn't want to spend $600 to put in a generater switch and $800 on a generator. This was perfect. And I can also use it if I want to go camping! It weights close to 30lbs, so you wouldn't want to carry it far, but it easily powers my c-pap for an entire night. Based on another review I expect I could get 2 nights per full charge.
