Appliance Surge Sizer: Will Your Power Station Start It?
A refrigerator that runs at 150W can demand 2400W for a fraction of a second when the compressor starts — and it's the station's surge rating, not its continuous rating, that decides whether it starts at all. Pick your appliance (or enter the compressor's LRA from its nameplate) and see which stations we track clear the spike.
Appliance figures are published typical ranges and manufacturer surge multipliers, not tested values — real units vary by ±30% with age and temperature. Station surge and output ratings come from manufacturer specs. Method: how we research.
1. What are you starting?
Full-size refrigerator (18–25 cu ft)
Needs 1200–2400W surge
For reliable starts, size to the top of the range — a station whose surge rating only clears the bottom may work with a newer, efficient unit and fail with an older one.

Go deeper:
- Surge watts vs running watts — why stations shut off, the full appliance surge table, and the sizing rule.
- Power station port wattage limits — the per-port ceilings that trip gear even when total watts look fine.
- Can a power station replace a UPS? — the other spec that surprises people: transfer time.
