According to the hype there is nothing preventing a solar panel from feeding the recharging power. Sounds like it has full cell monitoring and controls.

I tried a LI 12v battery booster for a backup plan with my CPAP. It only lasted about 4 hours. Got it on Amazon and returned it when it didn't work. Decided that these are great for short bursts of power, or long stretches at low current. This one sounds different.

I have one designed for use with CPAP, 250WH, roughly 20AH. runs my CPAP for 3+ nights if the humidifier heater etc. is turned off.

My CPAP uses around 6-7 AH/night.

one good night with the humidifier on.

I got one thru the VA not that one plus a cord to plug into a 12 volt outlet. I can get a couple of days out of it before charging it. That with the humd turned off

Still around $10 per amp. Too rich for my blood.
