Review on Rechargeable 12V 11000MAh 9V 14500MAh 5V 26400MAh DC Output Lithium-Ion Battery Pack For LED Strip, CCTV Camera, Portable Li-Ion Power Bank With AC/DC Charger - Black by Brian Thao

Nice versatile Battery. I bought it for camping with my Phillips Respironics System One 460PBT. I turn off the humidifier and get about 2.5 full nights sleep on it. It uses the 12V output.It also will work as a gigantic USB 5V power supply. Charges my phone many times. Never counted but it goes for a long long time. .also works as a 9 Volt supply (but I've not used it that way)It seems pretty well built.I bought a second one, for longer camping, more capability and redundancy.This newer one is a bit different than my first one, Nothing really important. it used to have five power lights, now it has four, The 9Volt output is now yellow. The wall power pack has a bit different current level, it's bumped to 1.5 amps for a bit faster charge.I also ordered the TalentCell DC 12V Power Cord, 5.5 x 2.1mm Male to DC7406 Male Plug Power Supply Cable. It works great and is a nice answer for plugging in my System one. I used a two adapter combination before, this is much much better than converting the battery connection to a 12 Volt Lighter plug and then from the Lighter to the CPAP connector with the official Philips adapter. It's cheaper, simpler and smaller. I guess the dual adapter approach does allow a plug into 12V car power, but, frankly I never used it.Gives me the ability to go National Park camping, nice!
