EcoFlow DELTA 3 Max Plus vs Anker SOLIX F2000
Anker has stopped selling the SOLIX F2000, and the spec that would have settled this anyway is surge: 6,000W on the DELTA 3 Max Plus against 2,800W, on the same 2,048Wh battery.

Spec deltas
Anker no longer sells the SOLIX F2000 (also sold as the PowerHouse 767), so this page has one candidate: the EcoFlow DELTA 3 Max Plus. Anker points F2000 shoppers to the SOLIX C2000 Gen 2 instead. It isn't on this page, so if you're set on Anker, compare that one against the DELTA directly.
The retirement isn't doing all the work. Both units carry a 2,048Wh battery and a 1,000W solar input, so runtime is identical on every load we model. The inverter is where they split: 3,000W continuous and 6,000W surge on the DELTA, 2,400W and 2,800W on the F2000. The DELTA is also 16.5 lbs lighter (50.7 against 67.2) and rated for at least 4,000 cycles to 3,000.
The F2000 kept two things the DELTA doesn't match. It rolls on wheels with a tow handle, a top reason reviews say owners chose itB1, and it has a 30A RV outlet where our DELTA record shows none. If you own one and it lives in an RV, it was built for your job. Everyone shopping today gets the DELTA.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
A motor has to clear the ceiling with its startup spike, not its running draw. Even at the gentle 2x end of that rule, the F2000 tops out starting motors that run around 1,400W (2,800 divided by 2), while the DELTA's line sits at 3,000W (6,000 divided by 2), its whole continuous rating. For motor loads, the F2000 behaves like a much smaller unit than its 2,400W label.
DELTA 3 Max Plus: 3,000W continuous, 6,000W surgeSOLIX F2000: 2,400W continuous, 2,800W surgeMotors briefly draw 2-3x their running watts at startup
Why it mattersIf the plan includes a compressor, a pump or power tools, the DELTA is the one that starts them; an F2000 owner should check the heaviest motor's startup draw against 2,800W before an outage does it for them.
The 2,048Wh base misses a van-life day by 2,944Wh on either unit, so expansion is the only way either covers it. That 4,685Wh day sits under half of the DELTA's 10kWh ceilingA4; on the F2000 you'd be growing a unit its maker has stopped selling.
SOLIX F2000 retired 2026-08-30; Anker names the SOLIX C2000 Gen 2 as its replacementBoth are expandable from a 2,048Wh baseDELTA 3 Max Plus scales from 2kWh up to 10kWh via Smart Extra BatteriesA4Van Life Daily needs 4,685Wh: 2,944Wh short on either base unit
Why it mattersAnyone buying with plans to add capacity later should start on the DELTA; an F2000 owner who wants more should confirm what expansion Anker still supports before spending on it.
The battery is the same 2,048Wh and the solar input the same 1,000W, so an F2000 owner switching to the DELTA buys surge headroom and a lighter lift, and gives up the RV outlet and the wheels. For a rig whose heaviest motor starts under 2,800W, that trade runs the wrong way.
SOLIX F2000: one RV 30A outlet, two 12V car outputs; DELTA 3 Max Plus: no RV 30A outlet, one 12V car outputSOLIX F2000: 67.2 lbs on 4.72-inch wheels with a retractable tow handleB1Reviews call the F2000 usually quiet and capable on typical RV loads: fridge, CPAP, lights, fansB3
Why it mattersIf your F2000 lives in an RV, keep it; if you're buying for an RV today, the DELTA is the only one on sale, so work out how it will feed your rig without a 30A RV outlet before it arrives.
The specific dimensions that decide these two units — everything else is a tie.
What the Specs Don't Tell You
Selected because: Surge headroom is the widest spec gap in this pair: 3,000W above the running rating on the DELTA, 400W on the F2000.
rated cycles
Six cards fire, and surge is the one that changes what you can plug in. The F2000 will run 2,400W all day, provided that load never asks for more than 2,800W on the way up, and motors always ask. The DELTA has 3,000W of room above its running rating, enough to start at 2x anything it can run.
The rest are smaller. UPS switchover is rated no worse than 10ms on the DELTA and no worse than 20ms on the F2000, which matters only if a fussy desktop PC is on the circuit. Cycle life runs at least 4,000 against 3,000, or 11 years against 8.2 at a full cycle a day. Warranty is 5 years on both, and only the DELTA publishes a noise figure, a spec-sheet 30dB rather than a measurement.
Growth Path
Selected because: Both expand from 2,048Wh, but only the DELTA's base is still on sale, and that base falls short of multi-day loads on either unit.
Both take expansion batteries, which would make this a wash if both were for sale. Growth only counts if you can buy into it, and buying an F2000 now means building on a base Anker has stopped selling. The DELTA scales from 2kWh to 10kWh with EcoFlow's Smart Extra Batteries, a setup reviewers describe as polishedA4.
The 2,048Wh base needs that ceiling for the long jobs. A van-life day at 4,685Wh runs 2,944Wh past what either unit delivers, and a 2,100Wh camping weekend runs 359Wh past it. On the DELTA either gap is one battery purchase away. On an F2000 you own, ask Anker what it still supports before you buy anything to bolt on.
Portability & Form Factor
Selected because: The F2000 is 16.5 lbs heavier yet rolls on wheels, so which one is easier to move comes down to stairs.
weight
On a flat floor the heavier unit is the easier one to move. The F2000 weighs 67.2 lbs, 16.5 more than the DELTA's 50.7, but it rolls on 4.72-inch wheels with a retractable tow handle, and reviews name that as a top reason owners picked itB1. Across a garage or an RV site, you pull it like a suitcase.
Wheels stop helping at the first step. Basement stairs, a truck bed, a back seat: there the F2000 is a 67.2-lb dead lift and the DELTA's lighter body wins outright. Our record doesn't give the DELTA wheels, so plan on carrying it, two hands, every time.
Your Life, Your Pick
Selected because: Identical batteries give identical runtime on every load we model, including a blackout that finishes with 96Wh to spare.
Same battery, same flat 85% derate, same answer on every row: each delivers about 1,741Wh usable, and every scenario lands at an identical percentage on both. Capacity cannot pick a winner here, which is why the inverter and the retirement have to.
The blackout row is the one to read twice. An 8-hour outage uses 1,645Wh, 94% of what either can deliver, leaving 96Wh at the end. That's a pass with almost nothing in reserve, so an outage that runs long becomes a job for the 1,000W solar input both units share.

Scenario verdicts
We ran the math on six real-world scenarios. Here's which unit survives your actual life.
SCN-01 · 2 nights · needs 2,100Wh
Weekend Camping
Two nights off-grid with essential comfort
Neither unit
Neither covers it from the base box. A 2,100Wh weekend is 359Wh more than the roughly 1,741Wh either can deliver, so both get you about 83% of the way, and both take 1,000W of solar, which makes the shortfall a panel problem rather than a battery one. The tie breaks on the walk to the site: the DELTA is 16.5 lbs lighter, and it's the only one still on sale.

8-Hour Blackout
Keep the essentials running through a night without power
Either unit
Both make it, with almost nothing left: 1,645Wh is 94% of what either can deliver, leaving 96Wh at the end. Capacity can't separate them. The switchover rating can, slightly: no worse than 10ms on the DELTA against 20ms on the F2000, which matters only if a fussy desktop PC is on the circuit.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
Both carry a CPAP through the night on about 18% of their usable energy, so capacity decides nothing. The DELTA publishes a 30dB spec-sheet figure; the F2000 publishes none, which isn't proof it's louder. For a new buy, the DELTA is the only one on sale.

Either unit
Both cover the day on 52% of their usable energy. The split is in the laptop ports: the DELTA's best USB-C port delivers 140W against the F2000's 100W, which skips the inverter and its losses on a power-hungry laptop, while the F2000 has three USB-C ports to the DELTA's two.

Conclusion
October 11, 2026
Verdict: the DELTA 3 Max Plus, on Power Score margin
Buy the EcoFlow DELTA 3 Max Plus. Anker has stopped selling the SOLIX F2000, so it can't be the recommendation, and the spec sheet points the same way regardless: both hold 2,048Wh and take 1,000W of solar, but the DELTA runs 3,000W against 2,400W, surges to 6,000W against 2,800W, weighs 16.5 lbs less and is rated for at least 4,000 cycles to 3,000. If you want to stay with Anker, its named replacement is the SOLIX C2000 Gen 2, which isn't on this page; hold it against those DELTA figures before assuming it matches. If you already own an F2000 that lives in an RV, its wheelsB1 and 30A RV outlet are reasons to keep it, not to replace it.

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 4.3/5 (59th percentile of 28 Large-class units), and SOLIX F2000 rates 3.8/5 (30th percentile of 28 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.
67.2 lbs, but It Rolls
The F2000 weighs 67.2 lbs, 16.5 more than the DELTA's 50.7, and on a flat floor that barely matters: it rides on wheels with a retractable tow handle, so you pull it like a suitcase. The weight comes back at the first step. Stairs, a truck bed or a back seat turn it into a 67.2-lb lift, and that's where the lighter DELTA wins. Our record doesn't give the DELTA wheels, so plan on carrying it.
A 6,000W Ceiling Against 2,800W
The DELTA surges to 6,000W, double its 3,000W running rating; the F2000 surges to 2,800W, only 400W above its 2,400W. Motors draw two to three times their running watts for an instant at startup, so even at the gentle end of that rule the F2000 tops out starting motors that run around 1,400W (2,800 divided by 2), while the DELTA's line sits at its full 3,000W rating. The F2000 still starts plenty; check the heaviest motor's startup draw against 2,800W rather than its label.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The DELTA 3 Max Plus is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The SOLIX F2000 is rated ≤20ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. If a computer with unsaved work is the thing being protected, the stated class is worth the attention; nothing here is a lab result.
Same 5 Years, Only One Still on Sale
Both carry a 5-year term on our record, so coverage doesn't separate them on paper. The DELTA's term comes with a unit you can buy new from EcoFlow today. The F2000 has left Anker's range; if you find one in retailer stock, confirm with the seller that the full term applies to your purchase before you count on it. If you already own one, check your purchase date against that 5-year term.
Battery Lifespan in Real Years
The DELTA 3 Max Plus is rated for 4,000 cycles vs 3,000. In real life: at daily use, that's 11 vs 8.2 years. At weekend use (twice a week), it's 38 vs 29 years. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.
SOLIX F2000: Noise Level Not Disclosed
The DELTA 3 Max Plus publishes its noise level (30dB); the SOLIX F2000 doesn't publish one. That isn't evidence the SOLIX F2000 is louder — it means there's no figure to hold it to, and no way to compare the two on this without hearing them. If you're buying for a bedroom, a CPAP, or an apartment, treat the DELTA 3 Max Plus's 30dB as the only published number on the table — a spec-sheet figure, not a measurement — and look for hands-on reports of the SOLIX F2000 before deciding.

Analyst note
The SOLIX F2000 is no longer sold, so there is no price to work its cost per kWh from, and this comparison doesn't quote one. On what you can actually buy today, the DELTA 3 Max Plus works out at $0.15/kWh over its rated life. If you already own the SOLIX F2000, the hardware comparison still holds: over its rated life the DELTA 3 Max Plus delivers about 8,192 kWh and the SOLIX F2000 about 6,144 kWh.

Worth knowing
Support quality appears to be declining from its historically excellent level. Firmware updates have removed features without warning. Expansion ecosystem is smaller than EcoFlow's.
Analyst note
With the F2000 retired, the brand question is whether to follow Anker to the SOLIX C2000 Gen 2 or move to EcoFlow. EcoFlow runs the larger ecosystem, with more expansion options behind the DELTA, but its support is inconsistent and it offers no parts or service once the warranty ends. Anker's support has a strong history that is trending down on SOLIX units, its expansion ecosystem is the smaller of the two, and firmware updates have removed features without warning. Neither is a clean win on trust, so buy from a retailer with an easy return policy whichever way you go.

Analyst note
Growth only counts if you can still buy in, and the SOLIX F2000 is no longer sold (Anker points owners to the SOLIX C2000 Gen 2). That leaves the DELTA 3 Max Plus: it starts at 2,048Wh and takes EcoFlow expansion batteries, so the ceiling moves if your needs do. The SOLIX F2000's expandability still matters if you already own one, but it isn't a reason to pick it over the DELTA 3 Max Plus.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3 Max Plus
What exists so far comes from reviewers rather than long-term owners; our research notes owner data is still accumulatingA0. The consistent theme is quiet: one tester's meter barely registered above room noise at one meter even while charging at full power, with the fans spinning up only briefly at shutdownA2. Reviews confirm the 3,000W continuous and 6,000W surge that set it apart in this pairA1.
Charging speed is the other repeated note: about 50 minutes to 80% and around 70 minutes to full in one reviewA3. Expansion from 2kWh to 10kWh through Smart Extra Batteries, with five ways to charge, is described as polished and effortlessA4.
“Bumps output to 3,000W continuous with a 6,000W surge — a significant upgrade over the DELTA 3 Max's 2,400W and 4,800W surge.”

Who Should Buy Which
Buy the DELTA 3 Max Plus if you…
- →You're buying a 2kWh unit today and need it to start motors: a 6,000W surge covers a 2x startup on anything up to its full 3,000W rating.
- →Your backup lives in the basement and comes upstairs when the lights go out: at 50.7 lbs it's 16.5 lbs less to haul than the F2000.
- →You expect to grow: Smart Extra Batteries take it from 2kWh to 10kWh, comfortably past a 4,685Wh van-life dayA4.
- →It's going beside a bed: EcoFlow publishes a 30dB spec-sheet figure, and one tester found it barely audible over room noise even charging flat outA2.
Buy the SOLIX F2000 if you…
- →You already own an F2000 that lives in an RV: it has the 30A RV outlet and the wheelsB1 on the same 2,048Wh battery as the DELTA, so keep it.
- →You own one and rarely start anything big: same battery, same 1,000W solar input, same runtime on every load we model, so replacing it buys you nothing you'll use.
- →You're set on Anker: the F2000 is gone, so look at the SOLIX C2000 Gen 2, Anker's named replacement, and check its surge and weight against the DELTA's before you buy.
If neither fits
Close this tab if the thing you need to back up runs on 240V, like a well pump on a 240V circuit or a dryer: neither unit has a 240V outlet on our record, so look at split-phase home backup systems instead. The same goes for anyone who wants a whole van-life day from the base box, since both deliver about 1,741Wh usable against a 4,685Wh day.
The Bottom Line
Buy the EcoFlow DELTA 3 Max Plus. The SOLIX F2000 has left Anker's range, and even before it did, the DELTA had the spec that matters most in a 2kWh box you lean on in an outage: 6,000W of surge against 2,800W, on the same 2,048Wh battery. The F2000 can run 2,400W; it just can't start a motor anywhere near that size.
If you already own an F2000 and it rolls around an RV, keep it, because nothing here runs longer. If you're shopping Anker, the SOLIX C2000 Gen 2 is the one to hold up against the DELTA. Everyone else: go get the DELTA.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Anker SOLIX F2000 discontinued?
Yes. Anker no longer sells the SOLIX F2000, also known as the PowerHouse 767, and names the SOLIX C2000 Gen 2 as its replacement. The F2000's specs on this page are still accurate for anyone who owns one. For a new purchase, the live unit here is the EcoFlow DELTA 3 Max Plus.
Should I buy the EcoFlow DELTA 3 Max Plus or the Anker SOLIX F2000?
The DELTA 3 Max Plus. Anker has stopped selling the F2000, and the DELTA beats it on the spec sheet anyway: 3,000W against 2,400W continuous, 6,000W against 2,800W surge, 16.5 lbs lighter, and rated for at least 4,000 cycles to 3,000. Both hold 2,048Wh, so runtime is identical.
I own an F2000. Is the DELTA 3 Max Plus worth upgrading to?
Usually not. Both hold 2,048Wh and take 1,000W of solar, so the DELTA runs nothing longer. It's worth it if a motor you need to start overshoots the F2000's 2,800W surge, or if you carry the unit up stairs often. If yours rolls around an RV, its wheels and 30A RV outlet make it the better fit for that job.
Which one is better at starting a fridge, compressor or power tools?
The DELTA 3 Max Plus. Its 6,000W surge is double its 3,000W rating, while the F2000 surges to 2,800W, only 400W above its 2,400W rating. Motors draw two to three times their running watts for an instant at startup, so check your heaviest one's startup figure against those ceilings. Neither has a 240V outlet, so a 240V well pump is out for both.
Is the DELTA 3 Max Plus quiet enough for a CPAP?
Yes, and capacity isn't the question: an overnight CPAP uses about 18% of its usable energy. EcoFlow publishes a 30dB figure, a spec-sheet number rather than a measurement, and one tester found it barely registered above room noise even while charging at full power. The F2000 publishes no noise figure, which isn't proof it's louder, just nothing to hold it to.
