| Rated capacity | 1,024 Wh[source]'Capacity 1024 Wh'. US model is DYM1000L. This is the original Power 1000, not the later Power 1000 V2. | 1,024 Wh[source]1024Wh 51.2V 20Ah. Not the same product as the DELTA 3 / DELTA 3 Plus / DELTA 3 Max. |
| Usable capacity (measured) | 775 Wh[source]techtest.org: 'Im Test schwankte die Kapazität der DJI Power 1000 zwischen 775 Wh und 862 Wh' (76-84% of the rating); the low end is used. The test does not state its voltage, but techtest.org is a German site and likely tested the EU 230 V unit. No US-unit test found. | Not publishedno independent test found. thesolarlab.com reports about 83% inverter efficiency but does not publish a measured Wh figure. |

Runtime = usable capacity ÷ average draw, the same formula for both models (no idle draw added to either), after checking continuous output and startup surge. Usable capacity is an independent test's measured figure, or 80% of rated where none exists. See the methodology.
