I thought most refrigerators could be plugged into regular 15Amp sockets. Since 15A*120V=1800W doesn't that mean a 2000W surge would trip the breaker? |

These are specs of the device you quoted in your OP. That device ECO flow RIVER Pro $649 Capacity:720Wh Life Cycles: 800+ Cycle Output: 600W (Surge 1200W) AC Input: 660W Max Its output is only 600W and quotes a 1200W surge. Surge is the maximum very short term output the generator can produce to get a motor started. If the spec is accurate it is unable to produce the surge necessary to get the compressor on a larger fridge started. In answer to your question above a 15 amp breaker would probably not trip on a 2000W load for several minutes from a cold start. As the breaker heated up from continuous overloads that time would get shorter. A 15 amp breaker would likely handle a 3000W surge load if it was of short duration. Breakers are only designed to handle 80% of name plate rating on a continuous basis. So a 15 amp breaker should only have 15 X 80% = 12 amps 12A X 120V = 1440 watts maximum load if it is classified as a continuous load. "but if you make yourselves sheep, the wolves will eat you."
