Estimated runtime

on a single full charge

Est. usable (AC): 196 Wh

Appliance draw: 60 W

Continuous output: 200 W

How we calculated this

We start from the Anker 521 PowerHouse's 196 Wh of estimated usable energy at the outlet — its 256 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the mini fridge's 60W draw:

196 Wh ÷ 60 W ≈ 3.3 hours

Heads up: a mini fridge is a motor/compressor load that spikes 2–3× on startup. The Anker 521 PowerHouse's 200W continuous / 400W 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.
