| Spec | BLUETTI EB3A | EcoFlow RIVER 2 | 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. | 268 Wh | 243 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. | 600 W | 300 W | 20% |
| Max solar inputHigher solar input means faster recharging off-grid, if you have enough panels to use it. | 200 W | 110 W | 15% |
| WeightLighter is easier to carry to a campsite or between rooms. | 4.6 kg | 3.5 kg | 15% |
| Max AC charging powerMore AC input watts means a faster wall recharge before a trip or storm. | 350 W | 360 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. | 2500 cycles | 3000 cycles | 10% |
| Surge / peak outputShort bursts for motor start-up (fridges, pumps). Skipped when the maker doesn't publish a surge figure. | 1200 W | 600 W | 5% |
| Chemistry | LiFePO4 | LFP | info |
