Will the Anker 535 PowerHouse run a full-size fridge?

Yes — the 535 PowerHouse runs a full-size fridge comfortably

Its 500W continuous output easily covers the 150W draw, with 1000W of surge on tap for startup.

Est. usable (AC): 392 Wh

Appliance draw: 150 W

Continuous output: 500 W

How we calculated this

We start from the Anker 535 PowerHouse's 392 Wh of estimated usable energy at the outlet — its 512 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the full-size fridge's 150W draw:

392 Wh ÷ 150 W ≈ 2.6 hours

Heads up: a full-size fridge is a motor/compressor load that spikes 2–3× on startup. The Anker 535 PowerHouse's 500W continuous / 1000W surge output has plenty of headroom for that spike.

Real-world runtime varies with temperature, cable losses, and how hard the appliance actually cycles. Treat this as a solid estimate, not a guarantee.
