EcoFlow DELTA 2 Max vs Anker SOLIX F2000
Anker has stopped selling the SOLIX F2000 and points buyers to the SOLIX C2000 Gen 2. Against the DELTA 2 Max the old F2000 still makes a clear trade: wheels and a heavier body on one side, a lighter lift and a much taller surge ceiling on the other.

Spec deltas
The Anker SOLIX F2000 has left Anker's range. Anker now points buyers to the SOLIX C2000 Gen 2. So if you're shopping, the EcoFlow DELTA 2 Max at $1,049 is the one of these two you can actually buy. If you own an F2000, this page shows how it compares.
On paper the two are twins in the places that count most. Same 2,048Wh battery, same 2,400W inverter, same 3,000-cycle LFP rating, and both take expansion batteries. They split on how they move and how hard they can kick. The F2000 rolls on built-in wheels with a pull-out handle, which owners cite as the top reason they chose itB1. It needs them, because it weighs 67.2 lb.
The DELTA 2 Max is 16.5 lb lighter and has a far taller surge ceiling, the brief burst an inverter can supply while a motor starts. I'd care about that second part. A fridge or a well pump can draw two to three times its running watts for a moment at start-up, and the DELTA has much more room for that.
What the Numbers Reveal
Each conclusion stated first β the numbers behind it on one line, the full analysis below.
What decides whether a motor starts is the ceiling. The F2000 still reaches 2,800W, so check your heaviest motor against that figure rather than assuming it trips. Anything that kicks harder is safer on the DELTA 2 Max.
the F2000 surges to 2,800W on a 2,400W inverterthe DELTA 2 Max surges to 4,800W on the same 2,400W continuousfridges and pumps can briefly draw two to three times their running watts at start-up
Why it mattersCheck the start-up draw of the heaviest motor you plan to run against 2,800W. If it's close or over, the DELTA is the safer choice.
weight
The DELTA 2 Max is 16.5 lb lighter, which matters on stairs or into a truck bed. The F2000's wheels let you roll its extra weight across flat ground insteadB1. Which is easier depends on the ground between your shelf and your outlet.
the DELTA 2 Max weighs 50.7 lb vs the F2000's 67.2the F2000 rolls on built-in wheels with an EasyTow handleB1both hold the same 2,048Wh
Why it mattersLift it often and the DELTA wins. Roll it over pavement and the F2000's wheels do.
The F2000's case used to be value and wheels. Value can't be judged for a unit that isn't sold. Its wheels and its owners' goodwill are still real for anyone who has one.
the DELTA 2 Max is on sale at $1,049, $0.17 per lifetime kWhthe F2000 is retired; Anker names the SOLIX C2000 Gen 2 as its replacementboth share the same 2,048Wh, 2,400W and 3,000-cycle LFP
Why it mattersBuying new, weigh the DELTA 2 Max against the C2000 Gen 2. Owning an F2000, there's nothing here that says replace it.
The specific dimensions that decide these two units β everything else is a tie.
What the Specs Don't Tell You
Selected because: Surge ceiling (4,800W vs 2,800W) and weight are the spec splits that still matter to owners and shoppers.
Surge is the clearest spec split, and it favours the DELTA 2 Max. It can reach 4,800W for a start-up burst against the F2000's 2,800W, on the same 2,400W continuous rating. The F2000 will still start plenty of loads. A hard-starting compressor or pump has more room on the DELTA.
Noise is murkier. EcoFlow publishes a best-case 30dB figure, and reviewers say the DELTA's fans get loud under heavy load or while chargingA1. Anker publishes no figure for the F2000, and an RV reviewer calls it usually quiet for typical loadsB3. Those aren't measurements of the same thing, so I wouldn't pick a winner on noise.
Lifetime Value
Selected because: Only the DELTA 2 Max is still sold, at $1,049 and $0.17 per lifetime kWh; the F2000 has no live price.
Both are rated for 3,000 cycles, about eight years of daily use, and both carry five-year warranties. On lifespan they tie.
On value, only one can be priced. The DELTA 2 Max is $1,049, which works out to $0.17 per lifetime kilowatt-hour. The F2000 no longer has a live price because Anker no longer sells it. If you're comparing costs, put the DELTA 2 Max against the SOLIX C2000 Gen 2 instead.
Portability & Form Factor
Selected because: Lighter lift (DELTA) vs wheels (F2000) is the practical trade.
weight
Portability pulls two ways. The DELTA 2 Max weighs 50.7 lb to the F2000's 67.2, so it's much easier up stairs or into a vehicle. The F2000 rolls on wheels with a retractable EasyTow handle, the feature owners cite mostB1, so over flat ground you never pick it up.
If I had to get it down a steep gravel drive, I'd rather carry the lighter box. On a garage floor or an RV pad the wheels win easily. Neither is simply more portable. They're portable in different ways.
Brand Trust
Selected because: EcoFlow's ecosystem vs Anker's app and support record, with the F2000 now retired.
Both brands are broadly trusted. EcoFlow has the deepest range and a well-rated app, though support reports are mixed. Anker has its consumer-electronics reputation, a well-liked app, and owners who report it fixing issues through firmware or replacement unitsB2.
With the F2000 retired, brand trust mostly matters to owners now. If you have one, Anker's support record is a reasonable comfort. If you're buying new, the choice is between EcoFlow's live unit and Anker's newer C2000 Gen 2.

Weekend Camping
Two nights off-grid with essential comfort
Neither unit
Neither covers a full two-night, 2,100Wh load on one charge, so plan to top up from solar. Both take the same solar input. Getting to the site is the split. The F2000 rolls on its wheels, and the lighter DELTA is easier over rough ground.

8-Hour Blackout
Keep the essentials running through a night without power
Either unit
Both cover a standard eight-hour outage with the same thin reserve. The difference is start-up. If the outage means running a fridge, the DELTA 2 Max's 4,800W ceiling starts the compressor with more room than the F2000's 2,800W. Same runtime, different headroom.
Battery budget usedlower = more headroom
LOADΒ Β Fridge 150WΓ8h Β· Router + Modem 20WΓ8h Β· LED Lights (4 bulbs) 40WΓ6h Β· Phone Charger 15WΓ3h
SCN-03 Β· 8 hours Β· needs 320Wh
CPAP Overnight
Sleep therapy without interruption β the #1 medical use case
Either unit
A CPAP leaves either unit with nights to spare, so the bedside question is noise. EcoFlow publishes a best-case figure for the DELTA 2 Max and Anker publishes none for the F2000. Those two facts can't be compared, so I wouldn't call a winner here without hearing both.
Battery budget usedlower = more headroom
LOADΒ Β CPAP Machine 40WΓ8h
SCN-04 Β· 8 hours Β· needs 910Wh

Tailgate Party
Game day power for the crew
Either unit
Both handle game day easily. Since capacity isn't the deciding factor, weight is: at 50.7 lbs the DELTA 2 Max is the one you'll be glad you brought. Fan noise under load is worth a listen too β it's audible in the lulls between songs.

Neither unit
Neither unit covers this scenario's 4,685Wh: the DELTA 2 Max comes up 2,944Wh short (about 37% covered), the SOLIX F2000 2,944Wh (37%). Treat this as partial cover β enough for the essentials in it, not the whole list.

Conclusion
October 25, 2026
Verdict: the EcoFlow DELTA 2 Max
Take the EcoFlow DELTA 2 Max, the only one of the two still on sale. Anker no longer sells the SOLIX F2000 and names the SOLIX C2000 Gen 2 as its replacement. On the specs the pair is close. Both hold 2,048Wh, put out 2,400W, are rated for 3,000 cycles and expand. The DELTA 2 Max is 16.5 lb lighter to lift and surges to 4,800W where the F2000 stops at 2,800W. The F2000 answers with built-in wheels and an EasyTow handle that owners rate highly. If you already own an F2000, keep it. If you're buying, the comparison worth making is the DELTA 2 Max against the C2000 Gen 2.

How the class ranking is computed βTest Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
SOLIX F2000: 67.2 lbs Is a Commitment
The DELTA 2 Max is 16.5 lb lighter, 50.7 to the F2000's 67.2. The F2000 rolls on built-in wheels with an EasyTow handle, so on flat ground it is easier to move despite the weight. Lifting favours the DELTA. Rolling favours the F2000.
Surge Power: Inverter Quality Indicator
The DELTA 2 Max surges to 4,800W against the F2000's 2,800W, on the same 2,400W continuous rating. The F2000's ceiling still starts many loads. For a hard-starting fridge or pump, check its start-up draw against 2,800W before you trust the F2000 with it.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here.
SOLIX F2000: Noise Level Not Disclosed
EcoFlow publishes a best-case 30dB figure for the DELTA 2 Max, which means it gets louder under heavy load. Anker publishes no figure for the F2000. That isn't proof either way. If the unit is going in a bedroom, look for hands-on reports.

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 2 Max works out at $0.17/kWh over its rated life. If you already own the SOLIX F2000, the hardware comparison still holds: each delivers about 6,144 kWh over its rated life. One thing to know reading the table: both carry the same 3,000-cycle rating, so the lifetime rows are sticker price and capacity in disguise β the wear horizon is identical and decides nothing here.

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
EcoFlow brings the deepest range and a well-rated app. The DELTA 2 Max is its older generation, with a strong surge ceiling and fans that get loud under load. Anker brings its consumer-electronics reputation, a well-liked app and a wheeled design owners love. With the F2000 retired, the live comparison is the DELTA 2 Max against Anker's SOLIX C2000 Gen 2.

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 2 Max: 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 2 Max.
What Owners Report

EcoFlow DELTA 2 Max
The DELTA 2 Max has a reputation as a durable unit. Its LFP cells are rated for 3,000-plus cycles, and one reviewer found no structural wear after six months of useA3. It also charges quickly from the wall, about 80% in 50 minutesA2. Reviewers still call it worth buying, with caveatsA4.
The main caveat is noise. Its fans get loud under heavy load or while charging, and a Quiet Charging mode helps at the cost of a slower chargeA1. Giving it some clearance for airflow helps tooA1.

The F2000's owner reviews keep coming back to how it moves. Its wheels and retractable EasyTow handle let it roll like luggage, and owners cite that as a top reason they chose it over similar unitsB1. Its WiFi and Bluetooth app gets praise, and a good number of owners report Anker fixing problems with firmware updates or replacementsB2. An RV reviewer found it usually quiet and quick to set up for typical loadsB3.
It uses Anker's long-life LFP, rated for over 3,000 cyclesB4. Anker has since retired it, so the people still reading these reviews are mostly owners.
βIt's big and full of heavy batteries, but the durable 4.72-inch wheels and retractable EasyTow handle make it surprisingly easy to lug around β most positive reviews cite the wheels and telescoping handle as a top reason owners chose it over similar-spec competitors.β

Who Should Buy Which
Buy the DELTA 2 Max if youβ¦
- βAnyone buying new. It's the one of the two still on sale.
- βYou run motor loads. Its 4,800W surge ceiling leaves more room for a hard-starting fridge or pump than the F2000's 2,800W.
- βYou lift the unit. At 50.7 lb it's 16.5 lb lighter than the F2000.
- βYou want fast wall charging, about 80% in 50 minutesA2.
Buy the SOLIX F2000 if youβ¦
- βYou already own one and it covers your loads. Keep it.
- βYou roll it over flat ground. The wheels and EasyTow handle beat carryingB1.
- βIf you want this kind of Anker new, look at the SOLIX C2000 Gen 2, which Anker sells in its place.
If neither fits
Both are 2kWh units, and neither covers a two-night camping trip or a full van-life day on one charge. Both expand, so either can grow, but plan the expansion battery into the budget from the start if those are your weekends.
The Bottom Line
Take the EcoFlow DELTA 2 Max. Anker has retired the SOLIX F2000, so the DELTA is the one you can buy. It's also the lighter lift and has much more surge headroom for motors.
If you own an F2000, keep using it. The wheels are as good as owners sayB1, and the core specs match the DELTA's. If you're shopping and liked the F2000's idea, put the SOLIX C2000 Gen 2 next to the DELTA 2 Max before you decide.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
EcoFlow DELTA 2 Max vs Anker SOLIX F2000: which should I buy?
The DELTA 2 Max, because the F2000 is no longer sold. Anker names the SOLIX C2000 Gen 2 as its replacement. The two share 2,048Wh, 2,400W and a 3,000-cycle rating. The DELTA 2 Max is 16.5 lb lighter and surges to 4,800W against 2,800W. The F2000 has built-in wheels. If you own an F2000, there is no reason to replace it.
Can the F2000 start a fridge?
Check its start-up draw first. The F2000 surges to 2,800W on a 2,400W inverter, and fridge compressors can briefly draw two to three times their running watts at start-up. Compare your fridge's start-up figure against 2,800W. The DELTA 2 Max's 4,800W ceiling leaves much more room for hard-starting motors.
Which is easier to move?
It depends how you move it. The DELTA 2 Max is 16.5 lb lighter (50.7 vs 67.2), so it's easier to lift up stairs or into a truck. The F2000 has built-in wheels and an EasyTow handle, so rolling it over flat ground is easier despite the extra weight.
Which is better value?
Only the DELTA 2 Max can be priced, because the F2000 is no longer sold. Both are rated for the same capacity, output and cycle life. To judge value on a new purchase, compare the DELTA 2 Max against Anker's SOLIX C2000 Gen 2.
