| Spec | DJI Power 500 | EcoFlow RIVER 2 Max | Weight |
|---|---|---|---|
| Battery capacityUsable runtime scales with watt-hours. A 1,000 Wh station runs a 100 W load for roughly 8–9 hours once inverter losses are counted. | 512 Wh | 499 Wh | 25% |
| Continuous AC outputThe rated (continuous) inverter output decides which appliances you can plug in. We use the rated figure, not surge or 'boost' modes. | 1000 W | 500 W | 20% |
| Max solar inputHigher solar input means faster recharging off-grid, if you have enough panels to use it. | Not listed | 220 W | 15% |
| WeightLighter is easier to carry to a campsite or between rooms. | 7.3 kg | 6 kg | 15% |
| Max AC charging powerMore AC input watts means a faster wall recharge before a trip or storm. | 540 W | 660 W | 10% |
| Rated cycle lifeHow many full cycles the maker rates the battery for. Thresholds differ (70% vs 80% remaining capacity), so read the note under each product. | 4000 cycles | 3000 cycles | 10% |
| Surge / peak outputShort bursts for motor start-up (fridges, pumps). Skipped when the maker doesn't publish a surge figure. | Not listed | 1000 W | 5% |

What we like
- 1,000 W continuous AC, the most here
- SDC port for fast DJI drone charging
- Dual USB-C 100 W
Watch out for
- DJI doesn't list a surge or a solar input wattage
- Heavier than the 600 W-class rivals
EcoFlow RIVER 2 Max
Better published figure on: Weight, Max AC charging power.
What we like
- 499 Wh in 13.2 lb
- 220 W solar input
- 100 W USB-C in and out
Watch out for
- 500 W inverter won't run a kettle or hair dryer
Verdict
DJI has twice the AC output (1,000 W) and drone fast charging; EcoFlow is lighter and publishes a 220 W solar input.
