From the specs

CPAP users: follow your doctor’s and the device maker’s advice on backup power.

Motors and solar

2,700 W surge, per BLUETTI. Some fridges need two to three times their running power to start (Anker), some compressors two to four times (BLUETTI); check yours. Own draw: about 15 W (manual), included in every runtime here.

Solar: up to 500 W, about 3.1 sun hours to full by our math.
