Amazon links here are affiliate links: we may earn a commission, at no cost to you. It does not change our numbers. How that works.
Price checked October 3, 2026; Amazon shows today’s price. This is the listing we matched to the bare unit, not a bundle.
Planning figures: a typical fridge averages about 84 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 2026-10-01)
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.

The range behind that
This is a 3,072Wh battery with 3,600W of output, which means it stores about 2,611 watt-hours you can actually use 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 7.5–131 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 | $1,349 | 2,611 Wh | $517 |
Per usable kWh = Amazon price divided by usable energy. Usable energy is 85% of the maker’s battery size, the same share we use everywhere on this site. Station price checked October 3, 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 2026-10-01 snapshot names this exact model (1 recalls name the brand; none names this model).
This check cannot clear your own unit. Most recalls cover only certain serial numbers. Read the model and serial number off the label on the unit itself, then check the maker's recall page before you use it, sell it, or buy it.
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.
Buying the right one

Title states 3072Wh and 3600W, matching the maker's figures exactly. Prices change: Amazon shows today’s price.
Some links on this page are affiliate links. If you buy through one we may earn a commission, at no extra cost to you. It does not affect which products the planner recommends: rankings come from the sizing rules on our methodology page, and a product whose recall status is unclear is never ranked or linked, whatever the commission.
