Est. usable (AC): 343 Wh

Appliance draw: 150 W

Continuous output: 700 W

How we calculated this

We start from the Bluetti AC50B Portable Power Station's 343 Wh of estimated usable energy at the outlet — its 448 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the full-size fridge's 150W draw:

343 Wh ÷ 150 W ≈ 2.3 hours

Heads up: a full-size fridge is a motor/compressor load that spikes 2–3× on startup. The Bluetti AC50B Portable Power Station's 700W 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.
