EcoFlow DELTA Pro
On one charge the EcoFlow DELTA Pro runs a typical refrigerator about 26 hours, and runs an older furnace blower about 14 hours.
Buy it if you want 3,600 Wh in one box for a fridge through a long outage, with room to add extra batteries later.
Skip it if you need 240 V for a well pump: it has none on its own. Skip it too if a fridge is the main job: the EcoFlow DELTA 3 Ultra runs one about as long for $500 less today. What to buy instead.

Price checked November 1, 2026; Amazon shows today’s price. This is the listing for this model on its own, not a bundle.
Planning figures: a typical refrigerator averages about 83 W; an older furnace blower averages about 182 W. Yours may use less or more; the range is in the table below. How long other power stations run a refrigerator. A furnace blower is wired in: it needs an inlet or transfer switch fitted by an electrician.
- Wall recharge
- up to 1,800 W from the wall
- Extra batteries
- Yes, 3.6 to 25 kWh with DELTA Pro Smart Extra Batteries
- Recalls
- no CPSC recall names this exact model (screened 2026-10-09)
Check you have the right model. Not the same as: EcoFlow DELTA Pro 3 (a similar name, a different model: 4,096 Wh, 4,000 W). Read the model name on the unit’s label, not the box or the listing.
How long will the EcoFlow DELTA Pro run a fridge, CPAP, sump pump or furnace?
| Appliance | Average draw | On one charge | Starts it? |
|---|---|---|---|
| Fridge, new and efficient (ENERGY STAR) | 54 W | about 34 h | starts it |
| Fridge, typical | 83 W | about 26 h | starts it |
| Fridge, old or large | 130 W | about 19 h | starts it |
| CPAP, heated humidifier on | 55 W | about 4.1 nights (33 h) | starts it |
| CPAP, humidifier off, from the 12 V car socket | 11.2 W | about 24 nights | starts it |
| Sump pump | 136 W | about 18 h (5.6–42 h) | starts it |
| Gas furnace blower, older single-speed | 182 W | about 14 h (3.6–20 h) | starts it |
| Gas furnace blower, variable-speed | 132 W | about 18 h | runs it |
| Well pump (240 V) | 65 W | — | needs 240 V |
One appliance at a time, from the 3,600 Wh battery, counting the power it uses just to stay on (2,780 Wh usable at a 300 W load). Fridge figures come from ENERGY STAR’s list of certified models, plus a 20 W allowance for the power station’s own draw and doors opening. CPAP with the humidifier on is the middle of the 30–100 W a CPAP with a heated humidifier draws; humidifier off is ResMed’s own 12 V figure for an AirSense 10 on ResMed’s DC cord. A night is 8 hours. Pumps and blowers switch on and off, so their average draw is far below their running watts; the hours are hours of outage, and the range runs from one that runs often to one that rarely does. A furnace blower is wired in: it needs an inlet or transfer switch fitted by an electrician. It has no 240 V output, so it cannot run a 240 V well pump (needs 240 V); a 120 V well pump is a different case, so check the pump’s label.

The range behind that
This is a 3,600Wh battery with 3,600W of output, which means it gives back about 2,780 watt-hours at a typical household load (estimated) and can run anything drawing up to 3,600 watts at once.
It runs indoors and makes no fumes. Of the 16 household loads we track, it can run 15 for at least part of a day. It would keep a refrigerator going for 19–34 hours, from a hard-working fridge to an efficient one.

Hours of use on one charge. Typical is the middle of our range for that appliance; the range runs from a hard-working unit to an efficient one. Short-burst loads (microwave, coffee maker, garage door) show running time at full power instead. “Starts it” means the peak output covers even a hard-starting one.
What a kilowatt-hour costs
| What | Amazon price | Usable energy | Per usable kWh |
|---|---|---|---|
| The station | $1,799 | 2,780 Wh | $647 |
Per usable kWh = Amazon price divided by usable energy: what the unit gives back at a typical 300 W household load, counting the power it uses just to stay on. The same rule runs everywhere on this site (how). Station price checked November 1, 2026; we show prices only on the day they were checked and keep no price history.
