I did some investigation over the Alpicool C20 and it seems to employ at most 72Ah @ 12V for every 24h, that is 864 watt-hrs. I’d expect it to use a bit below that as it gained’t be managing the compressor 24/7. of https://blancheqxnq698027.blogkoo.com/best-portable-power-station-can-be-fun-for-anyone-50114113
