About Best Portable Power Station
I did some study about the Alpicool C20 and it appears to employ at most 72Ah @ 12V for each 24h, that's 864 watt-hrs. I’d assume it to use a little bit under that because it won’t be jogging the compressor 24/7. Take note that according to the top quality, these inverters may not be particularly as powerful given that the ranking indicates.
