What can it run, and for how long?
Estimates assume ~85% inverter efficiency and average running wattage. Motor-driven appliances also need surge headroom.
| Appliance | Typical draw | Estimated runtime |
|---|---|---|
| LED bulb | 10 W | 13 days |
| Wi-Fi router + modem | 15 W | 9 days |
| CPAP machine (no humidifier) | 40 W | 3 days |
| Starlink (standard kit) | 50 W | 3 days |
| Box fan | 50 W | 3 days |
| Laptop | 60 W | 2 days |
| 55" LED TV | 100 W | 31 hours |
| Full-size refrigerator (avg) | 150 W | 20 hours |
| Mini fridge (avg) | 60 W | 2 days |
| Coffee maker | 900 W | 3.4 hours |
| Microwave (700W cooking) | 1000 W | 3.1 hours |
| Space heater | 1500 W | 2.0 hours |
For CPAP users: that's roughly 9.6 nights of sleep (8h/night, humidifier off).

FAQ
How long will the EcoFlow DELTA Pro run a refrigerator?
Around 20 hours for a full-size refrigerator averaging 150W, assuming ~85% inverter efficiency. Actual runtime depends on the fridge's compressor duty cycle and ambient temperature.
Does the EcoFlow DELTA Pro use a LiFePO4 battery?
Yes. It uses LiFePO4 (LFP) cells rated for about 3,500 cycles to 80% capacity — roughly 10+ years of daily cycling.
What solar panels work with the EcoFlow DELTA Pro?
Any panel (or array) within its 11-150V MPPT voltage window and up to 1600W, connected via XT60/MC4-adapter. Staying inside the voltage window matters more than matching wattage.
How fast does the EcoFlow DELTA Pro recharge from a wall outlet?
About 120 minutes from 0 to 80% on AC power.
