This is a battery power test of the RockPals 500w Lithium power generator running the Alpicool C50 from a frozen state until the battery is completely drained. At 50% the Alpicool’s voltage protection system kicked in using the DC outlet. Then the AC adapter was used with the inverter running. The system worked for just under 29 hours before the inverter shut off with 4% battery remaining. The Alpicool pulled around 30w at steady state with initial compressed draw of up to 40w. Much less power consumption than I expected.
