EcoFlow DELTA 4 (DELTA 3000 Gen4 and DELTA 3800 Gen4) Portable Power Stations
EcoFlow’s DELTA 4 Is Here. Is It Worth $2,199?
Yes, if you can wait. It landed on EcoFlow’s US store today, and it isn’t the unit Japan got. The US DELTA 4 runs 3,600 W at 120 V, charges at 1,800 W and is rated for 6,000 cycles. The DELTA 4 (3800) still puts 3,763 Wh in 67.5 lb. Here’s every US spec, what it costs, and who should order one.

The short answer
Order the DELTA 4 (3800) if 3.8 kWh at 67.5 lb is what you’ve been waiting for and you can live without it until late November. If the box will never need more battery, the (3000) is $500 less and ships in early December. If you need backup this week, the units below ship now.

01 · What was announced
What EcoFlow said, and what it means
Announced October 21, 2026 in EcoFlow Japan’s press release. The framing below is ours; every figure in it is graded in the ledger that follows.
The DELTA 4 (3800) puts 3.8 kWh in 67.5 lb, and we had to read that twice. The lightest unit near that size in our catalog is Jackery’s HomePower 3600 Pro Max, which carries 3,584 Wh at 73.85 lb. EcoFlow’s own DELTA Pro carries 3,600 Wh at 99 lb.
The DELTA 4 (3000) is the DELTA 3 Ultra in a smaller box. Same 3,072 Wh, same 3,600 W in the US, 14.8 lb lighter. The DELTA 3 Ultra is still on EcoFlow’s US store beside it.
The weigh-in
About the same battery. About half the weight.
Anker’s SOLIX F3800 carries 3,840 Wh at 132.3 lb. The DELTA 4 (3800) carries 3,763 Wh at 67.5 lb. Playground physics did the rest, and someone under the hedge is having a similar morning.

03 · Our arithmetic
What the published numbers imply
EcoFlow has published no runtimes and no charging-circuit requirement. These are estimates from EcoFlow’s figures, and they are labelled Power Station Arena analysis everywhere they appear.
| Load | DELTA 4 (3000) | DELTA 4 (3800) |
|---|---|---|
| 150 W — Laptop, router and lights | 17 h | 21 h |
| 800 W — A domestic fridge cycling | 3.3 h | 4.0 h |
| 1,500 W — One 15 A corded tool at full draw | 1.7 h | 2.1 h |
| 3,600 W — The full continuous rating | 44 min | 53 min |
Assumes 85% of rated capacity reaches the load — the same planning constant our comparison engine uses for every station. Real runtime at 3.6 kW will also depend on how the pack derates in heat, which nobody has measured yet.
Power Station Arena analysisWhat the charging claims imply
EcoFlow hasn’t published a US charge time yet. At the full 1,800 W the (3800) would refill in a little over two hours on paper; Japan’s 1,500 W unit is rated at about 2.8 hours.
Power Station Arena analysis Surge headroom
7,200 W peak is 2.0× the continuous rating.
Power Station Arena analysis Expansion arithmetic
Growing from 3.76 to 12 kWh means adding about 8 kWh with two extra batteries on EcoFlow’s expansion adapter. EcoFlow quotes 4–12 kWh; the DELTA 4 (3000) does not expand.
Good to knowEvery estimate above updates automatically if EcoFlow revises a published figure; nothing here is typed in by hand.
04 · Our take
What the DELTA 4 is really for, and who it is aimed at
Analysis by the Test Desk — not a summary of EcoFlow’s release or anyone else’s coverage. Every comparison figure below comes from the named maker’s own page.
The US got the better DELTA 4. Japan’s version runs 3,000 W at 100 V. Ours runs 3,600 W at 120 V with a 7,200 W surge, charges at 1,800 W instead of 1,500 W, and EcoFlow now publishes a 6,000-cycle rating and a noise figure. Same box, same battery, same weight. The extra 600 W is what lets it start the things a house actually runs.
It costs more than we guessed. Before launch we estimated about $1,300 and $1,800 from EcoFlow’s Japan-versus-US pricing. EcoFlow listed $1,699 and $2,199. Some of that buys the bigger inverter Japan didn’t get. Some of it is launch pricing on a unit that won’t ship for weeks, and EcoFlow’s own store already shows an early-bird offer below the list price.
The weight is still the headline. The DELTA 4 (3800) stores about 56 Wh for every pound it weighs. The DELTA Pro 3 manages 36 and Anker’s SOLIX F3800 29. One adult can lift 67.5 lb onto a shelf, briefly, with a good back. We’d still buy the folding cart.
We’d order the (3800) unless you’re sure 3,072 Wh is enough forever. The (3000) has one 1,000 W solar input and no battery port. What you buy is what you keep. The (3800) adds a second 1,000 W input and takes EcoFlow’s DELTA 3 Max Plus or DELTA Pro 3 batteries, up to 12 kWh. The step up is $500 for 691 Wh plus all of that headroom.
Wall charging uses the whole circuit. 1,800 W at 120 V is 15 A, the full rating of an ordinary household circuit. On a kitchen or garage circuit shared with a toaster or a compressor, we’d set the charge rate lower in the app and wait a little longer.
The fridge figures are EcoFlow’s, not ours. Up to 70 hours on the (3800) and 58 on the (3000), with its Fridge Runtime Boost mode. A stocked fridge that gets opened at dinner will draw more, so we’d test it with groceries inside before planning a long weekend around those numbers.

Who should wait for it, and who should not
Read from what EcoFlow chose to announce and what it chose to leave out.
Worth waiting for if you are
- Apartment and condo backup. 3.8 kWh that sits beside a sofa, charges from a normal outlet and switches over in 10 ms for the fridge and router.
- Anyone who sent back a DELTA Pro because of the weight. The DELTA 4 (3800) holds more and weighs 31.5 lb less.
- Households planning solar later. The (3800) takes 2,000 W of panels and EcoFlow’s current expansion batteries.
Buy something that ships if you are
- Anyone who needs backup before late November. Neither size ships yet. The alternatives below ship now.
- 240 V loads. Both are 120 V only. A 240 V well pump or dryer needs something like the DELTA Pro 3.
- Buyers who want a 12 V car socket. Neither DELTA 4 has one.

Frequently asked
Short answers, each with its own link.
Yes. EcoFlow listed both sizes on its US store on November 4, 2026. EcoFlow says the DELTA 3800 Gen4 ships in late November and the DELTA 3000 Gen4 in early December.
The DELTA 3000 Gen4 lists at $1,699 and the DELTA 3800 Gen4 at $2,199 on EcoFlow’s US store. EcoFlow also sells kits with solar panels or a DELTA 3 Max Plus extra battery.
Close. EcoFlow sells them as the DELTA 3000 Gen4 and DELTA 3800 Gen4 and calls the series DELTA Gen 4. We call them the DELTA 4 (3000) and DELTA 4 (3800), as most buyers do.
The 3800 holds 3,763 Wh against 3,072 Wh and weighs 67.5 lb against 57.3 lb. It has two 1,000 W solar inputs to the 3000’s one and takes up to two extra batteries for 4–12 kWh; the 3000 does not expand. Both have 3,600 W of output, a 7,200 W surge, 1,800 W wall charging and a 6,000-cycle rating.
No. Japan’s version is rated 3,000 W with a 6,000 W surge at 100 V and charges at up to 1,500 W. The US version is rated 3,600 W with a 7,200 W surge at 120 V and charges at up to 1,800 W. Capacity, weight, solar input and the outlets are the same.
From EcoFlow’s US spec tables: LFP cells, 3,072 Wh (3000) or 3,763 Wh (3800), 3,600 W continuous, 7,200 W surge, five AC outlets (four at 20 A, one at 30 A), USB-C at 140 W and two at 65 W, one 36 W USB-A, up to 1,800 W wall charging, 1,000 W of solar on the 3000 and 2,000 W on the 3800, a switchover of 10 ms or less, 6,000 cycles, and 57.3 lb or 67.5 lb. The 3800 expands to 4–12 kWh.
