| Spec | EcoFlow DELTA 3 Classic | BLUETTI AC180 | 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. | 1024 Wh | 1152 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. | 1800 W | 1800 W | 20% |
| Max solar inputHigher solar input means faster recharging off-grid, if you have enough panels to use it. | 500 W | 500 W | 15% |
| WeightLighter is easier to carry to a campsite or between rooms. | 12.1 kg | 16 kg | 15% |
| Max AC charging powerMore AC input watts means a faster wall recharge before a trip or storm. | 1400 W | 1440 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. | Not listed | 3500 cycles | 10% |
