How long will the EcoFlow RIVER 2 Max 500 run a portable compressor fridge?
Can the EcoFlow RIVER 2 Max 500 start a portable compressor fridge?
Yes. A typical portable compressor fridge draws about 60 W running and up to 180 W starting, both inside the EcoFlow RIVER 2 Max 500’s published 500 W continuous and 1,000 W surge ratings. Your own unit’s nameplate can differ, so check it before relying on this.
How long will the EcoFlow RIVER 2 Max 500 run a portable compressor fridge?
Plan on 17 hr to 20 hr for a typical portable compressor fridge at a 35% duty cycle, about 21 W on average. That range applies 0.70 and 0.85 usable-capacity factors to the EcoFlow RIVER 2 Max 500’s 499 Wh, because inverter heat and battery management overhead consume the rest. Actual use depends on your own appliance and conditions.
Which station runs a portable compressor fridge longer than the EcoFlow RIVER 2 Max 500?
The EcoFlow DELTA 3 Plus is the next meaningful step up we’ve verified, at 34 hr or more on the same portable compressor fridge using the same conservative 0.70 factor, against 17 hr here. Only stations that pass both the continuous and surge checks count as upgrades in the table below, so it’s a fair comparison.
| Station | Capacity | Cautious | Best case | Continuous | Surge |
|---|---|---|---|---|---|
| EcoFlow RIVER 2 Max 500 | 499 Wh | 17 hr | 20 hr | Pass | Pass |
| EcoFlow DELTA 3 Plus | 1,024 Wh | 34 hr | 41 hr | Pass | Pass |
| Jackery Explorer 1000 v2 | 1,070 Wh | 36 hr | 43 hr | Pass | Pass |
| BLUETTI AC180 | 1,152 Wh | 38 hr | 47 hr | Pass | Pass |
| Jackery Explorer 2000 v2 | 2,042 Wh | 2.8 days | 3.4 days | Pass | Pass |
| BLUETTI Elite 200 V2 | 2,073.6 Wh | 2.9 days | 3.5 days | Pass | Unverified |
| EcoFlow DELTA Pro 3 | 4,096 Wh | 5.7 days | 6.9 days | Pass | Pass |
What load does this portable compressor fridge estimate assume?
These figures are typical values, not measurements of your unit. We assume 60 W running, 180 W starting and a 35% duty cycle for a portable compressor fridge. Models vary widely, so enter your nameplate figure in the calculator above for a number that fits your own appliance and how you use it.
A 40 to 50 L compressor cooler on its AC adapter. Direct 12 V use avoids inverter losses and runs longer.
