EcoFlow DELTA 3 Plus

On one charge the EcoFlow DELTA 3 Plus runs a typical refrigerator about 9 hours, and runs an older furnace blower about 4.5 hours.

Buy it if you want up to 1,000 W of solar input, or an extra battery later (up to 5 kWh in all).

Skip it if you only need power at home in an outage. The EcoFlow DELTA 3 Classic has the same 1,024 Wh battery and 1,800 W output, so it runs a fridge just as long. What to buy instead.

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.

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 will the EcoFlow DELTA 3 Plus run a fridge, CPAP, sump pump or furnace?

Well pump (240 V)65 W—needs 240 V

One appliance at a time, from the 1,024 Wh battery, counting the power it uses just to stay on (847 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.

Who should skip the EcoFlow DELTA 3 Plus, and what to buy instead

Prices checked November 1, 2026.

The range behind that

This is a 1,024Wh battery with 1,800W of output, which means it gives back about 847 watt-hours at a typical household load (from independent tests) 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 12 for at least part of a day.

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.

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

WhatAmazon priceUsable energyPer usable kWh
The station$719847 Wh$849

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: 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.

Maker recall lookup

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.
