Don't get me wrong, there is nothing wrong with this backup battery, it simply doesn't supply enough power for what I purchased it for. That is my fault. My original intention was to use this to power my CPAP when camping and not having a power source available. I learned while using it that it can only power my CPAP machine, even with the humidifier and heater turned off, for about 7.5 hours. I was hoping for much more, but miscalculated the capacity when I purchased it. It does charge phones, tablets, etc., very well and for quite a few charges before needing to be charged itself. That is what I will be using it for in the future. Will consider purchasing a battery with much higher reserve and using a small generator to recharge it during the day in order to run my CPAP in the future.
