Green marks the better published figure. "Not listed" means the manufacturer doesn't publish it.
| Spec | Anker SOLIX F3800 Plus | EcoFlow DELTA Pro 3 | 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. | 3840 Wh | 4096 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. | 6000 W | 4000 W | 20% |
| Max solar inputHigher solar input means faster recharging off-grid, if you have enough panels to use it. | 3200 W | 2600 W | 15% |
| WeightLighter is easier to carry to a campsite or between rooms. | 62 kg | 51.5 kg | 10% |
| Max AC charging powerMore AC input watts means a faster wall recharge before a trip or storm. | 1800 W | Not listed | 5% |
| 240 V output (listed)240 V output runs well pumps, dryers and other 240 V circuits through a transfer switch or home panel. We mark Yes only when the maker lists 240 V output on the unit itself. | Yes | Yes | 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. | 3000 cycles | 4000 cycles | 10% |
| Surge / peak outputShort bursts for motor start-up (fridges, pumps). Skipped when the maker doesn't publish a surge figure. | Not listed | 8000 W | 5% |
