EcoFlow DELTA 2 Max: what can it run?
A 2,048Wh portable power station with a 2,400W AC inverter. It can start a full-size fridge and run one for an estimated 18h–27h.
Estimated AC runtime by device
Ranges use the low and high watt loads in our device data, from a full charge. They are planning estimates, not measured results for this model.
| Device | Load while running | Estimated runtime |
|---|---|---|
| Wi-Fi router | 8–20W | 55h–89h |
| Laptop, charging and active | 30–90W | 17h–42h |
| Full-size fridge | 150–250W · 35% duty cycle | 18h–27h |
For the fridge, the 1,200W startup assumption fits within this unit's 3,400W surge rating. Real fridge demand and cycling vary. A router may run longer from a compatible DC output, which this AC table does not model.
The specs that matter
- Battery: 2,048Wh LiFePO4, with an estimated 1,741Wh usable through AC at a moderate load, before idle draw.
- AC output: 2,400W continuous and 3,400W surge. Check the startup draw of motor loads.
- Weight: 50.7 lb.
- Cycle claim: EcoFlow states 3,000 cycles to at least 80% capacity. That is a battery-life claim, not a runtime promise.
On Sep 25, 2026, EcoFlow listed a 4,800W AC surge output alongside a 3,400W X-Boost figure. This page uses the lower X-Boost figure, which the unit can sustain.
Where the estimate can miss
The calculation uses a sourced 13.6W AC idle draw for this model. Idle draw matters most for a small load such as a router. Inverter efficiency is our class default. Temperature, battery age, output mode and the actual device load can all move the result.
The stated surge rating tells you what the inverter is designed to accept. It does not measure your fridge's startup spike. For essential equipment, measure the load and run a full-duration test.
Nearest models by capacity
The closest smaller and larger models with a guide on this site. Fridge estimates use the same 150–250W load and 1,200W startup assumption as the runtime table on this page.
