Green marks the better published figure. "Not listed" means the manufacturer doesn't publish it.
| Spec | EcoFlow DELTA 3000 Gen4 | EcoFlow DELTA Pro | 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. | 3072 Wh | 3600 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. | 3600 W | 3600 W | 20% |
| Max solar inputHigher solar input means faster recharging off-grid, if you have enough panels to use it. | 1000 W | 1600 W | 15% |
| WeightLighter is easier to carry to a campsite or between rooms. | 26 kg | 45 kg | 10% |
| Max AC charging powerMore AC input watts means a faster wall recharge before a trip or storm. | 1800 W | 1800 W | 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. | Not listed | No | 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. | 6000 cycles | 3500 cycles | 10% |
| Surge / peak outputShort bursts for motor start-up (fridges, pumps). Skipped when the maker doesn't publish a surge figure. | 7200 W | 7200 W | 5% |
| Chemistry | LFP (LiFePO4) | LFP | info |
| Cycle rating | 6,000 cycles (EcoFlow; threshold not stated) | 3,500 cycles to 80% (6,500 to 50%) | info |
| AC output | 5 outlets, 3,600 W total (surge 7,200 W); X-Boost 4,600 W | 5 outlets, 3,600 W total (surge 7,200 W); X-Boost 4,500 W | info |
| AC input | 1,800 W | 1,800 W at 120 V; 3,000 W at 240 V | info |
| Solar input | 1,000 W max | 1,600 W max, 11–150 V | info |
| USB-C | 140 W + 2 × 65 W | Not listed | info |
| Expansion | No (EcoFlow spec table) | Up to two DELTA Pro Smart Extra Batteries | info |
| Noise | ≤30 dB at 600 W (EcoFlow test) | Not listed | info |
