EcoFlow DELTA 3 Plus

The short answer

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 15 household loads we track, it can handle 13. It would keep a refrigerator going for 1.2–8.7 hours.

Check you have the right model

EcoFlow sells other models that can be mistaken for this one:

  • EcoFlow DELTA Pro 3 — they differ by a single word: PLUS against PRO. peak output 8,000W instead of 3,600W.
  • EcoFlow DELTA 3 Classic (1024Wh). same battery size and same output as this one.
  • EcoFlow DELTA 3 — one extra word: PLUS. same battery size and same output as this one.
  • EcoFlow RIVER 3 Plus — they differ by a single word: DELTA against RIVER. peak output 1,200W instead of 3,600W.
  • EcoFlow DELTA 2 (EFD330). same battery size and same output as this one; peak output 2,700W instead of 3,600W.

Read the full model name off the label on the unit itself, not off the box or the listing. The figures on this page apply only to the exact name in the heading above.

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.

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.

Manufacturer 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.

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 with unresolved safety identity is never ranked or linked regardless of commission.
