Quick Answer
👉 The best portable generator for a refrigerator is the Honda EU2200i.
It provides:
- enough startup power for most refrigerators
- quiet operation
- excellent fuel efficiency
👉 Most refrigerators need:
- 600–800 running watts
- 1200–2200 startup watts
Refrigerator Startup Surge (IMPORTANT)
Most people only look at running watts…
…but refrigerators use a startup surge when the compressor kicks on.
👉 This surge can temporarily double or triple power demand.
That’s why inverter generators around:
- 2000W–3000W
are usually ideal.
