|---|---|---|
| Rated capacity | 1,024 Wh[source]Specs tab: 'Capacity 1024 Wh'. Manual: '1,024Wh, 51.2V'. The official US info page still exists, but the us.ecoflow.com store URL (/products/delta-2-portable-power-station) now redirects to the DELTA 3, so the unit is no longer sold standalone on the official US store. | 1,070 Wh[source]30.4Ah/35.2V DC (1070 Wh). The official page also promotes the newer HomePower 1000 v2 ('Looking for a Newer, More Affordable Option?'), a different model. |
| Usable capacity (measured) | 850 Wh[source]StorageReview measured 0.85 kWh through AC at a 270 W load (120 V unit). EU 230 V units tested higher: nextpit 901 Wh at about 1,000 W; techtest.org 826 Wh (AC 125 W) and 903 Wh (AC 750 W). Lowest figure used. | 910 Wh[source]OutdoorGearLab measured 910 Wh out of 1,070 Wh (85%). nextpit.de measured 902 Wh; thesolarlab.com measured 87.5% efficiency at a 1,479 W load. |
| AC continuous output | 1,800 W[source]Specs tab: 'AC Output 6 ports, 1800W total (Surge 2700W)'. X-Boost is listed as 2400W on the specs tab but 2200W in the overview text and the user manual. | 1,500 W[source]'1500W Rated, 3000W Surge peak'. |
| AC surge output | 2,700 W[source]Specs tab and user manual agree: 'surge 2,700W'. | 3,000 W[source]In an independent test (thesolarlab.com) the unit held about 2,200 W for a couple of seconds before shutting off; the 3000 W figure is the official spec. |
