| Spec | Anker SOLIX C2000 Gen 2 | EcoFlow DELTA 2 Max | Weight |
|---|---|---|---|

| Continuous AC outputThe rated (continuous) inverter output decides which appliances you can plug in. We use the rated figure, not surge or 'boost' modes. | 2400 W | 2400 W | 20% |
| Max solar inputHigher solar input means faster recharging off-grid, if you have enough panels to use it. | 800 W | 1000 W | 15% |
| WeightLighter is easier to carry to a campsite or between rooms. | 18.9 kg | 23 kg | 15% |
