Gunner’s take
Whole-Home Backup Tester
The DELTA 4 (3000) carries half again the battery for 6.6 lb more.
It holds 3,072 Wh at 57.3 lb. The DELTA 3 Max Plus holds 2,048 Wh at 50.7 lb. The new box also runs a bigger inverter, 3,600 W against 3,000 W, with a 7,200 W surge against 6,000 W.
The bigger box costs about the same per watt-hour.
EcoFlow lists the DELTA 4 (3000) at $1,699 on its US storeB10, $500 more than the Max Plus at $1,199. That gap buys 1,024 Wh of battery, 600 W more inverter and a 6,000-cycle rating where the Max Plus has 4,000.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
The Max Plus runs out 359 Wh short of the weekend, and the DELTA 4 (3000) finishes with 511 Wh left. On a blackout night the Max Plus gets through with 96 Wh, 6% of a second night. The DELTA 4 (3000) still holds 59% of a second night, so the next evening starts on battery instead of a flashlight.
DELTA 4 (3000): 3,072 Wh; DELTA 3 Max Plus: 2,048 WhWeekend Camping needs 2,100 Wh; the Max Plus has 1,741 Wh usable after the flat 85% derate8-Hour Blackout: 966 Wh left on the DELTA 4 (3000), 96 Wh on the Max Plus
Why it mattersIf an outage or a camping trip has ever run past one day, the bigger battery is the reason to pay the gap.
The Max Plus's first extra battery spends itself catching up to a box that arrived with 3,072 Wh, and that battery is money on top of $1,199. Past that point the Max Plus keeps going and the DELTA 4 (3000) stops. A daily off-grid day like our Van Life Daily is out of reach for both on their own, and only the Max Plus can add its way toward it.
DELTA 4 (3000): no extra-battery port, sealed at 3,072 WhB6DELTA 3 Max Plus: takes EcoFlow's extra batteries up to 10kWhA4Van Life Daily needs 4,685 Wh: the DELTA 4 (3000) is 2,074 Wh short, the Max Plus 2,944 Wh short
Why it mattersIf you can already picture yourself adding batteries, start with the Max Plus. If one box is the whole plan, the sealed one is bigger.
cost / lifetime kWh
Per lifetime kWh it costs $0.09 against $0.15. That only bites if the box works every day. Run it off solar every evening and the DELTA 4 (3000)'s rating lasts 16.4 years of daily cycles against 11 for the Max Plus.
DELTA 4 (3000): 6,000 cycles at 3,072 Wh, about 18,432 kWh over its rated lifeDELTA 3 Max Plus: 4,000 cycles at 2,048 Wh, about 8,192 kWhCost per lifetime kWh: $0.09 against $0.15
Why it mattersIf it will cycle daily, the DELTA 4 (3000) is the cheaper box to own, gap included.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Weekend Camping splits them: 511 Wh to spare on the DELTA 4 (3000) against 359 Wh short on the Max Plus.
The weekend is where the smaller battery runs dry. Weekend Camping needs 2,100 Wh. After the flat 85% we count as usable, the Max Plus has 1,741 Wh and comes up 359 Wh short before Sunday is over. The DELTA 4 (3000) finishes with 511 Wh left.
The blackout looks like a tie until the second night. Both get through eight hours. The Max Plus ends at 94% used with 96 Wh, the DELTA 4 (3000) at 63% used with 966 Wh. If the lights stay off into a second evening, only one of them still has something to give. A CPAP night, a workday and a tailgate fit either one easily.
Growth Path
Selected because: Only the Max Plus takes extra batteries. The DELTA 4 (3000) is sealed at 3,072 Wh.
The Max Plus is the one with a door. It takes EcoFlow's extra batteries, up to 10kWh in allA4. The DELTA 4 (3000) has no extra-battery portB6, so it never holds more than the day it arrives. If you want a DELTA 4 that grows, EcoFlow builds that as the bigger modelB6.
I wouldn't buy the Max Plus just to expand it to this size. Its first extra battery mostly pays to catch up on 1,024 Wh the DELTA 4 (3000) already includes, and it's money on top of $1,199. Expansion earns its keep only if you'll keep going past 3,072 Wh, toward a battery that grows with the house.
Lifetime Value
Selected because: 6,000 cycles at 3,072 Wh against 4,000 cycles at 2,048 Wh.
cost / lifetime kWh
Over its rated life, the DELTA 4 (3000) moves more than twice the energy. 6,000 cycles at 3,072 Wh comes to about 18,432 kWh. The Max Plus's 4,000 cycles at 2,048 Wh comes to about 8,192 kWh. That works out to $0.09 per lifetime kWh against $0.15.
It only matters if the box works for a living. A backup that runs a few nights a year won't come near either rating. One that runs off panels every evening is spending cycles, and there the sealed box is the cheaper one to own, gap and all.
Portability & Form Factor
Selected because: 57.3 lb against 50.7 lb, and only the Max Plus has a 12 V car socket.
weight
The bigger battery costs 6.6 lb, and I'd barely feel it. 57.3 lb against 50.7 lb is the same one-person lift into a trunk. The DELTA 4 (3000) carries by a handle at each end, and EcoFlow sells a folding cart for it separatelyB7.
I'd check the car socket before the scale. Our record gives the Max Plus a 12 V car socket and the DELTA 4 (3000) noneB3. If the camping plan is a 12 V fridge on a car-style plug, that alone points to the Max Plus. On USB-C the DELTA 4 (3000) runs its two smaller ports at 65 W against 45 W.

Conclusion
November 4, 2026
Verdict: the DELTA 3000 Gen4, on Power Score margin
I'd buy the DELTA 4 (3000), unless you'll outgrow 3,072 Wh. For $500 more it holds 1,024 Wh more, runs 3,600 W against 3,000 W and carries a 6,000-cycle rating against 4,000, at about the same money per watt-hour. That battery is what finishes our camping weekend, which the Max Plus misses by 359 Wh. What you give up is the door: no extra-battery portB6, no 12 V car socketB3, and it ships in early DecemberB10. The Max Plus takes extra batteries up to 10kWhA4, so anyone planning to grow, or needing power before December, should take the Max Plus.

Power Score
Computed from 14 published spec dimensions, weighted per use-case bench. Higher is better; a unit must meet a bench's minimum threshold to be rated.
See the full weight table and data sourcing on our methodology page →Class ranking (the star rating)
Each unit's star score is a category ranking, not customer reviews — no buyer opinions feed it. We score every station on size-independent quality (value, output, portability, endurance, ports, warranty, and more), then percentile-rank it against the other units in its capacity class, so a class-leading compact unit and a class-leading whole-home unit can both earn 5★. Here, DELTA 3 Max Plus rates 4.2/5 (54th percentile of 29 Large-class units), and DELTA 3000 Gen4 rates 4.8/5 (86th percentile of 29 Large-class units).
How the class ranking is computed →Test Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
Sealed at 3,072 Wh
The DELTA 4 (3000) has no extra-battery port, so 3,072 Wh is the ceiling. The Max Plus starts at 2,048 Wh and takes extra batteries. Its first one mostly catches up, so expansion only wins if you'd keep going past 3,072 Wh.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. Both figures are maximums rather than guarantees — they depend on registering the unit in the EcoFlow app, which adds two years to a three-year standard term. Worth saying because the per-dollar framing can suggest otherwise: the DELTA 3 Max Plus works out at 4.2 years of cover per $1,000 spent against the DELTA 3000 Gen4's 2.9, but that spread is the price gap, not the terms.
Battery Lifespan in Real Years
The DELTA 3000 Gen4 is rated for 6,000 cycles vs 4,000. In real life: at daily use, that's 16.4 vs 11 years. At weekend use (twice a week), it's 58 vs 38 years. One caution reading years across different sizes: a cycle is 3,072Wh on the DELTA 3000 Gen4 and 2,048Wh on the DELTA 3 Max Plus, so count lifetime energy — roughly 18,432 kWh against 8,192 kWh over the rated life. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.
Full record above — the Test Desk pick is the DELTA 3000 Gen4.

Analyst note
Don't read the DELTA 3 Max Plus's expandability as a straight win here: it starts at 2,048Wh, below the DELTA 3000 Gen4's 3,072Wh, so a first expansion battery largely buys back capacity the DELTA 3000 Gen4 already includes. It only pulls ahead if you'd grow past 3,072Wh — short of that, the DELTA 3000 Gen4's larger fixed capacity is the simpler value.
What Owners Report

Nobody owns a DELTA 4 (3000) yet. EcoFlow put it on sale in the US on November 4 and says it ships in early DecemberB10, so this side of the page is EcoFlow's spec table and FAQ plus our own arithmeticB1B4.
I'd want to test its wall charger on a shared circuit. At 1,800 W on 120 V it draws 15 A, the full rating of an ordinary 15 A circuitB4. If I had one, I'd plug it into a garage outlet that shares a circuit with the freezer, run a full-rate charge and see whether the breaker holds. My guess is I'd end up turning the rate down in the appB4.

Buy the DELTA 3000 Gen4 if you…
- →One box is the whole plan. 3,072 Wh against 2,048 Wh, for 6.6 lb more.
- →Your outages run into a second night. It ends the eight-hour blackout with 966 Wh against 96.
- →You camp for the whole weekend. It finishes the 2,100 Wh weekend the Max Plus runs out on.
- →It will cycle every day. 6,000 cycles against 4,000, at $0.09 per lifetime kWh against $0.15.
If neither fits
If you already know you'll outgrow 3,072 Wh and want to start big, close this tab. Look at the bigger DELTA 4, which takes extra batteriesB6, or a home battery sized for the house from day one.
The Bottom Line
If one box is the plan, buy the DELTA 4 (3000). It's half again the battery for 6.6 lb more, and it's the one still running on the second evening.
If you'll grow, or you need power before it ships, buy the Max Plus. It's the smaller box with somewhere to go.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow DELTA 4 (3000) available in the US?
Yes. EcoFlow put it on sale at its US store on November 4, 2026 at $1,699, and says it ships in early December. The DELTA 3 Max Plus sells for $1,199.
Can you add an extra battery to the DELTA 4 (3000)?
No. It has no extra-battery port, so 3,072 Wh is all it will hold. The DELTA 3 Max Plus takes EcoFlow's extra batteries, up to 10kWh in all.
Is the DELTA 4 (3000) worth the extra money over the DELTA 3 Max Plus?
For one-box backup, yes. It costs $500 more and holds 1,024 Wh more, with a 3,600 W inverter against 3,000 W and a 6,000-cycle rating against 4,000. Per watt-hour the two cost about the same. If you plan to add batteries, the Max Plus is the one that can.
Which one charges faster from the wall?
One review had the DELTA 3 Max Plus full in about 70 minutes. The DELTA 4 (3000) charges at up to 1,800 W, which is 15 A at 120 V, the full rating of a 15 A circuit. It has a bigger battery to fill, and we have no timed full charge for it yet.
Does the DELTA 4 (3000) have a 12 V car socket?
No. EcoFlow lists no 12 V car socket on it. The DELTA 3 Max Plus has one, which matters if you run a 12 V fridge or cooler off a car-style plug.
