EcoFlow DELTA 2
A specification-based US-variant profile with an editable runtime model. Not a hands-on review or measured performance test.

What this profile can tell you
The capacity and output figures below come from the cited manufacturer material for the US model. Use them to test a specific load, compare size and weight, and identify specifications that still need confirmation. Calculated runtime is an estimate built from the assumptions you choose; it is not a measured claim about this unit.

Planning scenarios
These are calculated illustrations, not tests. Each assumes a new-capacity factor, a full starting charge, a 10% stopping reserve, 85% AC conversion efficiency, and 5 W of inverter idle draw. Replace them with your own settings in the runtime tool below.
| Sustained AC load | Battery-side demand | Estimated runtime | Output check |
|---|---|---|---|
| 50 W | 63.8 W | 14.4 hours | Below documented 1,800 W continuous limit |
| 100 W | 122.6 W | 7.5 hours | Below documented 1,800 W continuous limit |
| 300 W | 357.9 W | 2.6 hours | Below documented 1,800 W continuous limit |
A capacity-based runtime does not establish startup compatibility. The table also does not model charging while in use, temperature, battery management limits, or changing device loads.
Planning runtime
The station capacity and documented continuous output below are product facts. Efficiency, reserve, idle draw, and health remain editable planning assumptions, not measured model performance.

Tradeoffs and unresolved checks
- Surge duration and warranty were not established by the cited manual.
- USB/DC compatibility requires matching individual and shared port limits, voltage profiles, protocols, and cables.
- Solar input wattage alone does not establish voltage, current, polarity, or connector compatibility.
- Calculated runtime is not measured runtime and may differ with load, temperature, unit condition, and firmware behavior.

- EcoFlow: DELTA 2 User Manual — downloadable specifications (US/CA) — accessed 2026-10-01. Specifications on PDF pages 11–12 confirm capacity, US AC output, dimensions, weight, LFP chemistry, and charging limits. Surge duration and warranty term are not established. Cycle-life claim is left unresolved pending reconciliation with earlier product documentation.
