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 1,400 W from the wall; 0-80% in about 45 minutes via AC charging
- Extra batteries
- Not listed by EcoFlow
- 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 Plus (the same battery and output); EcoFlow DELTA 3 (the same battery and output); 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.

starts at up to 2,200 W |
starts it | about 17h | 3.9–73h |
| Sump pump | 700–1,500 W

| Coffee maker | 700–1,500 W | starts it | about 35 minutes of running time | short bursts |

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 | $499 | 870 Wh | $573 |
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.

Living with it
What the maker’s own pages and manual say about owning this unit, and what owners report in public. Each line links to where it was read. Nothing here is our own test.
- Switchover when the grid drops
- 10 ms (maker-stated standby-UPS transfer time)us.ecoflow.com
- Pass-through charging
- Supported as automatic 'Bypass Mode': charging and discharging via AC input/output simultaneously auto-enables bypass; a separate app toggle can force appliances to draw only from the battery (not raw grid) when bypass is active.images.thdstatic.com
- Wall recharge
- 0-80% in 45 minutes via AC charging (maker claim); AC input capped at 1400W maxus.ecoflow.com

- Cycle life
- No explicit cycle count published by EcoFlow for this model on the product page, support FAQ, or manual. The only maker-stated longevity figure is an estimated ~10-year lifespan from internal simulation testing (not a cycles-to-80% number). Third-party review sites cite '3,000+' to '4,000' cycles to 80% capacity, but that figure could not be verified on any EcoFlow-owned page for this specific SKU, so it is excluded here per sourcing rules.us.ecoflow.com
- Low-load shutoff
- Yes — the AC output auto-shuts-off after an idle timeout to save power; the timeout can be set to 'never' in the app for continuous loads like a fridge, and the manual warns this feature can false-trigger on intermittent loads (fridges/ACs cycling on and off).images.thdstatic.com
- App
- EcoFlow app, marketed on the product page as 'OASIS 3.0 Smart App Control'; the manual refers to it generically as 'the EcoFlow app'. Connects via Wi-Fi and Bluetooth.us.ecoflow.com
- Expansion
- Not listed. EcoFlow's DELTA 3 Classic page offers no extra battery for it.us.ecoflow.com

What owners report, from public threads and long-term reviews; not our own testing.
- One hands-on reviewer measured idle/standby power draw at roughly 17W and clocked inverter efficiency around 83%, both called strong for a budget-tier unit, plus near-silent operation at idle.thesolarlab.com
- Several reviewers independently flag the complete lack of a battery-expansion port as the unit's most common complaint, since sibling DELTA 3 models support add-on batteries and this one doesn't.prismopicks.com
- A reviewer noted the OASIS 3.0 app delivers solid monitoring but can feel complex for first-time users navigating its settings.prismopicks.com
- One reviewer ran a 60W mini-fridge on a full charge for about 14 hours, but found a small 5,000 BTU window AC unit drained the battery in under two hours, illustrating the real-world runtime gap between light and heavy loads.backuppowerhub.com
- Reviewers across multiple sites consistently point out the unit ships with only three AC outlets (one reportedly ungrounded), no 12V car-style DC outlet, and a 500W solar input ceiling that simply ignores extra wattage from larger panel arrays.thesolarlab.com
- A reviewer found EcoFlow's 'Smart Generator' compatibility claim for this model is misleading — in practice it just means the unit can be AC-charged from a generator, not that it has generator-specific automation.thesolarlab.com
- Reviewers note the unit has no built-in LED work light, unlike some competitors at a similar price point, which limits its usefulness for nighttime emergencies.thesolarlab.com
- The 500W solar input ceiling means pairing it with larger 600W+ panel arrays wastes the excess wattage since the unit will not accept more than its cap.backuppowerhub.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.
| Measurement | Result | Tester |
|---|---|---|
| Inverter efficiency, measured | ~83% inverter efficiency measured by the tester | The Solar Lab |
| Idle draw, measured | roughly 17W idle draw, as measured by the tester | The Solar Lab |
| Wall charge, empty to full | just shy of 55 minutes, empty to full, on a standard wall outlet | The Solar Lab |
| Also measured | About 2 hours to charge fully via solar panels in the tester's setup | The Solar Lab |
- A no-nonsense, budget-friendly portable power station well suited to camping or light emergency backup, though buyers wanting more ports/expandability should look elsewhere. The Solar Lab
- Rated 8.2/10 and called the best budget entry point into EcoFlow's DELTA 3 lineup, though this review is spec-based (real-world use photos, no lab measurements) rather than hands-on tested. Backup Power Hub
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.
