$516 per usable kWh at Amazon prices checked November 1, 2026 ($1,299 for 2,520 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
- Extra batteries
- No (the Ultra Plus takes 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 Plus (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.
What independent tests measured
- Power it uses just to stay on: 22 W with the AC outlets on and nothing plugged in (The Solar Lab).
- What we use: 2,520 Wh usable at a typical 300 W load; every hours figure on this page counts the idle draw (store estimated: no test at a stated load). The one rule we use.

The range behind that
This is a 3,072Wh battery with 3,600W of output, which means it gives back about 2,520 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 18–36 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 | $1,299 | 2,520 Wh | $516 |
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.

Recall screen
No published recall names this exact model
No CPSC recall in the 2026-10-09 recall list names this exact model (1 recall names the brand; none names this model).

Use the CPSC recall search.
How we know the screen was not simply blind
Finding nothing only means something if the search could have found something. So we searched the same records for this brand and got 1 recall. That proves the screen can see this brand, so finding nothing for this model is a real result.
