EcoFlow DELTA 3 Plus
On one charge the EcoFlow DELTA 3 Plus runs a typical fridge about 10 hours, and runs an older furnace blower about 4.8 hours.
1,024 Wh battery (870 usable)1,800 W output3,600 W peak
Amazon had no offer for the bare unit when we checked on October 3, 2026, so there is no buy link.
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 1,500 W from the wall; 0-100% in about 56 minutes at 1500W AC input
- Extra batteries
- Yes, via XT150 port; expandable up to 5 kWh total
- Recalls
- no CPSC recall names this exact model (screened 2026-10-01)
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); EcoFlow DELTA 3 Classic (1024Wh) (the same battery and output); EcoFlow DELTA 3 (a similar name with the same battery and output); EcoFlow RIVER 3 Plus (a similar name, a different model: 286 Wh, 600 W); EcoFlow DELTA 2 (EFD330) (the same battery and output). Read the model name on the unit’s label, not the box or the listing.
How long it runs each appliance
The same numbers as a table
| Appliance | Typical average draw | Hours on one charge |
|---|---|---|
| Fridge | 84 W | about 10 h |
| Furnace blower, older (PSC) | 182 W | about 4.8 h |
| Furnace blower, variable-speed (ECM) | 132 W | about 6.6 h |
| CPAP | 55 W | about 16 h |
| Sump pump | 136 W | about 6.4 h (may not start a hard-starting one) |
| Wi-Fi router and modem | 24 W | about 36 h |
| Laptop | 52 W | about 17 h |

The range behind that
This is a 1,024Wh battery with 1,800W of output, which means it stores about 870 watt-hours you can actually use and can run anything drawing up to 1,800 watts at once.
It runs indoors and makes no fumes. Of the 16 household loads we track, it can run 13 for at least part of a day. It would keep a refrigerator going for 2.5–44 hours, from a hard-working fridge to an efficient one.
These figures come from a non-US page
The source we captured for this model is a regional page, not the US one. The same product name can carry a different voltage and different outlets between regions, so treat these numbers as needing US confirmation.

| Coffee maker | 700–1,500 W | starts it | about 35 minutes of running time | short bursts |
| Television | 40–250 W | starts it | about 16h | 3.5–73h |
| Garage door opener | 300–800 W
starts at up to 1,800 W |
starts it | about 65 minutes of running time | short bursts |
| 12 V compressor fridge (camping) | 25–110 W
starts at up to 320 W |
starts it | about 47h | 16–139h |
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
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. Extra battery: EcoFlow lists several extra batteries that fit (DELTA 3, DELTA 2, DELTA 2 Max, DELTA Pro 3 packs), 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's bench measurements found the fan stayed near the maker's quiet claim (about 30 dB) under roughly 600W of load but climbed to about 40 dB once load reached around 1200W and up, and separately clocked the actual UPS transfer time at just over 8 ms, in line with the 10 ms spec.storagereview.com
- A reviewer testing real-world car charging found their older vehicle could not deliver the full rated 800W to the unit's car-charging input, so their 12V charge fell short of the advertised ~1.3-hour full-charge time; they also noted the unit ran warmer than expected even during light use like laptop charging.tech.yahoo.com
- The same reviewer said the cooling fan was audible even over background noise from a 700W vacuum running nearby, and that after checking other independent write-ups they found fan noise and temperature-control quirks came up as a recurring, not isolated, theme for this model.tech.yahoo.com
- A buyer posting in EcoFlow's own official owner Facebook group reported that their newly purchased DELTA 3 Plus battery drained unusually fast whenever the AC inverter was left switched on.facebook.com
- Fan noise and thermal/temperature management are flagged as a recurring weak point across more than one independent review of this model — the fan becomes clearly audible under moderate-to-heavy loads and the unit can run noticeably warm even during light charging tasks, which one reviewer felt could be a concern for long-term reliability under sustained heavy use.tech.yahoo.com
- Bench testing shows the real-world noise floor rises well above the "30 dB ultra-quiet" marketing figure once output climbs past about 1200W (measured around 40 dB), so the quiet rating mainly holds at lighter loads rather than across the unit's full output range.storagereview.com
What independent testers measured
We do not test units ourselves. These are figures published by testers who did, with the maker’s claim beside them where the tester gave it.
- Rated 8.5/10 and called the sweet spot between capacity and expandability in EcoFlow's DELTA 3 lineup, but the review itself is spec-based rather than lab-tested. Backup Power Hub
- In its DELTA 3 vs DELTA 3 Plus comparison, recommends the Plus specifically for buyers who value the doubled solar input and broader battery/USB-C support over the base DELTA 3. Backup Power Hub
Recall screen
No published recall names this exact model
The single EcoFlow recall (26010) names DELTA Max 2000, model EFD310, a previous-generation product. DELTA 3 Plus is not named.
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.
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.
