EcoFlow DELTA 3 Ultra Plus (3072Wh)
On one charge the EcoFlow DELTA 3 Ultra Plus (3072Wh) runs a typical refrigerator about 23 hours, and runs an older furnace blower about 12 hours.
Buy it if you want a big 120 V battery that takes extra batteries later.
Skip it if you need 240 V for a well pump: it has none. Skip it too if you will never add a battery. What to buy instead.

$662 per usable kWh at Amazon prices checked November 1, 2026 ($1,599 for 2,414 usable Wh). How we work it out
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; 0-80% in about 91 min, 0-100% in 120 min on AC power
- Extra batteries
- Yes, to 11 kWh with 2 DELTA Pro 3 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 3 Ultra (3072Wh) (a similar name with the same battery and output). Read the model name on the unit’s label, not the box or the listing.
How long will the EcoFlow DELTA 3 Ultra Plus 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 31 h | starts it |
| Fridge, typical | 83 W | about 23 h | starts it |
| Fridge, old or large | 130 W | about 16 h | starts it |
| CPAP, heated humidifier on | 55 W | about 3.7 nights (30 h) | starts it |
| CPAP, humidifier off, from the 12 V car socket | 11.2 W | about 21 nights | starts it |
| Sump pump | 136 W | about 16 h (4.8–39 h) | starts it |
| Gas furnace blower, older single-speed | 182 W | about 12 h (3.1–17 h) | starts it |
| Gas furnace blower, variable-speed | 132 W | about 16 h | runs it |
| Well pump (240 V) | 65 W | — | needs 240 V |
One appliance at a time, from the 3,072 Wh battery, counting the power it uses just to stay on (2,414 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 3,072Wh battery with 3,600W of output, which means it gives back about 2,414 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 14 for at least part of a day. It would keep a refrigerator going for 16–31 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 | $1,599 | 2,414 Wh | $662 |
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. Extra battery: The manual names a compatible Smart Extra Battery by example only, so there is no one pack to price.

What owners report, from public threads and long-term reviews; not our own testing.
- A hands-on reviewer measured idle power draw at about 24W with both inverter output sides switched on, dropping to about 22W with the 30A outlet turned off, calling the figures perfectly acceptable for a unit this size.thesolarlab.com
- The same reviewer found the cooling fans stayed unobtrusive even when the inverter was pushed to its maximum rated output, never becoming loud or distracting.thesolarlab.com
- Reviewers called out backward compatibility with older EcoFlow extra-battery packs as unusually generous, contrasting it with most competitors that force buyers into a new battery ecosystem with each new model.thesolarlab.com
- A reviewer noted that despite the unit's 74-lb weight and likely use during blackouts, it has no built-in light, which they felt would have been a helpful addition.thesolarlab.com
- Independent bench testing measured the UPS/EPS transfer time at about 8.25 ms (within EcoFlow's <10 ms claim) and put discharge efficiency around 85% and recharge efficiency around 87%, broadly matching or slightly beating the maker's own figures.storagereview.com
- Overload protection behaves unevenly: if total output exceeds the 3,600W rating, only the 30A outlet shuts off even when the overload originates on the standard 120V outlets, which one reviewer called impractical for whole-home backup wiring.thesolarlab.com
- The unit has no rubber bump-stops for when it is stood upright on its narrow end, which a reviewer flagged as a risk of scratching the plastic housing over time.thesolarlab.com
- Several buyers discussing the unit in online deal-forum threads noted it cannot output 240V the way the sibling DELTA 3 Pro can, which they said limits its usefulness for whole-home backup circuits that need 240V (e.g., well pumps, electric dryers).slickdeals.net
