EcoFlow DELTA 3 Ultra Plus vs Anker SOLIX F3000
Same battery, same inverter, same surge, so the whole decision is 17.2 pounds against 800 watts of solar ceiling, and you'll lift the box far more often than you'll max the array.

Spec deltas
Same 3,072Wh battery. Same 3,600W inverter, same 7,200W surge, same 4,000-cycle rating, same five-year warranty. Two companies arrived at nearly the same box, and every load we model lands on both of them identically: camping, blackout, CPAP, workday, tailgate, all a dead heat to the percentage point.
So take the DELTA 3 Ultra Plus at $1,599. The $99 premium over the F3000's $1,500 buys a lighter box at 74.3 lb against 91.5, a rated transfer of 10 ms or less instead of 20, a published noise figure where Anker gives none, and 140W over USB-C to the Anker's 100W. Both packs are rated for 4,000 cycles, so across the life of the pack the Anker's lower price makes its energy slightly cheaper: $0.12 per kilowatt-hour against the EcoFlow's $0.13.
The Anker's counter is narrow and it's real. It accepts 2,400W of solar against the EcoFlow's 1,600W, and it rolls: wheels and an extendable handle make the extra weight vanish on flat groundB1B8. If your array is already bigger than 1,600W, buy the F3000 and keep the change. If it isn't, you'd be paying for a ceiling you'll never reach and carrying it up the basement stairs.
What the Numbers Reveal
Each conclusion stated first β the numbers behind it on one line, the full analysis below.
solar input
That 800W of headroom is only spendable if you already own more than 1,600W of panels. Wall-charge the box and the ceiling is a number you will never once touch. Run it off a roof and a ground array in October and it's the single advantage on this page that money can't buy back on the EcoFlow.
SOLIX F3000 accepts 2,400W of solar input; DELTA 3 Ultra Plus accepts 1,600WBoth units hold 3,072WhThe F3000 sells for $1,500, the DELTA 3 Ultra Plus for $1,599
Why it mattersSolar-first buyers with a serious array should take the F3000 and pocket the $99. If your recharge plan starts with an extension cord, that ceiling shouldn't move you a dollar.
cost / lifetime kWh
Eleven years of daily cycling is well past the warranty window on either box, at a cost per kilowatt-hour you can check with a calculator before you spend anything. With the same rating and the same energy through the pack, the only thing that moves that cost is the sticker, and the Anker's lower price makes it the slightly cheaper unit to own.
DELTA 3 Ultra Plus is rated 4,000 cycles at 3,072Wh, or 12,288 kWh through the packAt $1,599 that's $0.13 per lifetime kilowatt-hour, and 11 years of daily cyclingThe SOLIX F3000 is rated for the same 4,000 cycles, which at $1,500 is $0.12 per lifetime kilowatt-hourBoth units carry a 5-year warranty at nearly the same cost per year of cover
Why it mattersDaily cyclers running a van, a cabin, or a solar-shifting setup get the same rated life from either, so weight and solar input should decide it. If this is a hurricane box that runs a dozen times a year, cycle life will never be the thing that decides anything.
weight
Wheels close the whole gap on flat ground and none of it on stairs, over a tailgate, or up into a truck bed, which is exactly where these boxes have to go. Neither unit is a casual carry. But 17.2 lb is small on paper and decisive halfway up a basement staircase with your fingers under a handle.
DELTA 3 Ultra Plus weighs 74.3 lb; SOLIX F3000 weighs 91.5 lbReviewers split on the F3000's liftability: one carried it solo without straining after a two-hour driveB1, another said it barely passed his own manual-lift testB8The F3000 has built-in wheels and an extendable handleB8A reviewer calls the Ultra Plus heavy and nowhere near lightweightA9
Why it mattersIf the unit rolls from garage to driveway and never climbs anything, weight is off the table and the Anker's lower price stands unopposed. If a staircase is anywhere in the route, take the EcoFlow.
The F3000 started a single brutal load that a household breaker refusesB9 and shut itself off when two kitchen appliances were stackedB2; the Ultra Plus sheds its 30A port first under overloadA3. With identical 3,600W ratings, plan on one big appliance at a time on either box; nothing in the record shows either inverter outdoing the other, so the question of which one is stronger is off the table for this pair.

Why it mattersIf you were shopping these two on inverter muscle, stop. Plan on running one big kitchen load at a time on either, and let weight, solar input, and transfer time decide instead.
The specific dimensions that decide these two units β everything else is a tie.
Portability & Form Factor
Selected because: 74.3 lb against 91.5 is the one difference every buyer feels, and the F3000's wheels only cancel it on flat ground.
weight
Seventeen pounds sounds like a modest gap until you find out where the line falls. The EcoFlow is a two-hands, bent-knees, don't-twist lift that one person can manage badly and two can manage well. The Anker at 91.5 lb is where reviewers stop agreeing with each other: one carried it alone after a two-hour drive to a picnic and didn't complainB1, another said it barely passed his own manual-lift testB8. That's not a disagreement about the spec. That's the same weight landing on different backs.
The F3000 answers with wheels and a telescoping handleB1B8, and on a driveway that's a complete answer. It's no answer at all on stairs, over a tailgate, or up into a truck bed. Work out which of those the box actually has to cross before you decide 17.2 lb is nothing.
Lifetime Value
Selected because: Both are rated 4,000 cycles, so cost per lifetime kilowatt-hour comes down to sticker price, where the Anker is slightly ahead.
cost / lifetime kWh
Four thousand cycles at 3,072Wh is 12,288 kilowatt-hours through the pack before it's finished, and $1,599 spread across that is $0.13 a kilowatt-hour. Cycle it every single day and the rating alone covers eleven years. The F3000 carries the same 4,000-cycle rating, so the same arithmetic on its $1,500 comes to $0.12, and the Anker is the slightly cheaper unit to own.
So lifetime value isn't where the EcoFlow earns its premium; it earns it on weight, transfer time and USB-C output. The five-year warranties cost nearly the same per year of cover on either unit, near enough to a wash, and both promise the same rated life after the coverage runs out.
Growth Path
Selected because: Both take expansion batteries, so the real question is refill: 2,400W of solar input on the F3000 against 1,600W on the DELTA 3 Ultra Plus.
solar input
Neither box tops out at 3,072Wh, since both accept expansion batteries, which turns the interesting question from whether you can grow into what you can feed the bank once it's grown. The F3000 takes half again more solar than the EcoFlow does, and that gap gets more important the bigger the bank gets. A battery you can't refill in a day is a battery that shrinks every day you use it.
EcoFlow runs the wider catalog, but width isn't what constrains you at a campsite in October. Input is. For a wall-charged house this is theoretical; for a cabin with a roof array and a couple of ground panels, it's the strongest argument on this page for the Anker, and it's one we'd act on.
What the Specs Don't Tell You
Selected because: Rated transfer times of 10 ms against 20 ms and an undisclosed noise figure on the F3000 are the flagged asymmetries once capacity and inverter match.
Two of the flags here are about what's printed, not what's broken. The EcoFlow is rated to hand over in 10 ms or less and the Anker in 20, and neither is slow; the EcoFlow simply holds the more conservative margin, which is what you want when the thing plugged in is a desktop mid-render rather than a lamp. The noise flag is a disclosure flag: EcoFlow publishes 30 dB, Anker publishes nothing, and reviewers describe both machines as quiet under heavy loadA1A13B5. A missing number isn't a loud fan. It's a missing number.
The flag that actually costs you something is weight, and it fires on both units. Neither of these is a box you move on a whim, and no card on this page will change that.
Your Life, Your Pick
Selected because: All six modeled loads come out identical on both units, which is the clearest proof that capacity decides nothing here.
Camping, blackout, CPAP, workday, tailgate: five loads, five dead heats, right down to the percentage. The same battery does the same work, which is the useful finding here even though it decides nothing. The sixth, daily van life, is the one neither of them wins, and it comes out identical too.
Daily van life runs 4,685Wh and both boxes hold 3,072Wh, so on that job you're not choosing a power station at all. You're choosing which expansion ecosystem to keep buying from, and that's where the solar ceiling starts to matter more than anything on the spec table.

Scenario verdicts
We ran the math on six real-world scenarios. Here's which unit survives your actual life.
SCN-01 Β· 2 nights Β· needs 2,100Wh
Weekend Camping
Two nights off-grid with essential comfort
Either unit
A weekend's 2,100Wh puts both units at 80% of what each can usably deliver, which is the same answer given twice. Break the tie on how the energy gets back in: if the plan involves panels on a picnic table, the F3000's higher solar ceiling refills sooner. If the plan is charging at home before you leave, take the 17.2 lb you don't have to haul to the site.

8-Hour Blackout
Keep the essentials running through a night without power
Either unit
Eight hours of the essentials is 1,645Wh, about 63% of either battery's usable capacity, so both come out the far side with something in reserve. The handover rating is the only real difference: 10 ms or less on the EcoFlow, 20 on the Anker, and neither is going to drop your router on the way through. Otherwise it's a coin flip, decided by which one you're more willing to drag out of the closet at 11 p.m.

CPAP Overnight
Sleep therapy without interruption β the #1 medical use case
Either unit
A CPAP night is 320Wh, about 12% of either unit's usable capacity, so capacity is emphatically not the question here. Roughly eight nights on one charge from either box. What matters three feet from your pillow is the fan, and only one of these two arrives with a published noise rating, which isn't proof the other is louder but is the only number either company will stand behind.

Either unit
Both handle game day easily. Since capacity isn't the deciding factor, weight is: at 74.3 lbs the DELTA 3 Ultra Plus 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.

Van Life Daily
A full day of mobile living β the ultimate endurance test
Neither unit
Neither unit covers a full van-life day. The load is 4,685Wh, both boxes hold 3,072Wh, and no amount of careful use closes a gap that size. On this job you're buying a base unit plus an expansion battery either way, which changes the question from which power station to which ecosystem, and the F3000's higher solar ceiling is what decides whether a bigger bank can actually be refilled in a day.

Conclusion
October 14, 2026
Verdict: the EcoFlow DELTA 3 Ultra Plus
Buy the DELTA 3 Ultra Plus at $1,599. It weighs 74.3 lb against the F3000's 91.5, is rated to hand over in 10 ms or less instead of 20, publishes a 30 dB noise rating where Anker publishes none, and pushes 140W over USB-C to the Anker's 100W. Both are rated for 4,000 cycles, so cycle life doesn't separate them. The $99 you'd save on the Anker is under 7% of the price and it buys back exactly one thing that matters: 2,400W of solar input against 1,600W. If your panels are already past 1,600W, or that array is a plan rather than a daydream, buy the F3000 and pocket the difference. If your recharge story starts at a wall outlet, take the lighter box with the published numbers.

Each unit's star score is a category ranking, not customer reviews β 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 5β . Here, DELTA 3 Ultra Plus rates 4.9/5 (96th percentile of 26 Large-class units), and SOLIX F3000 rates 4.8/5 (88th percentile of 26 Large-class units).
How the class ranking is computed βTest Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
Both of these are a plan-the-route lift
74.3 lb and 91.5 lb, and both sit well past the weight where you lift with your back and regret it that evening. The 17.2 lb gap is real and worth something, but it's the difference between heavy and heavier, not between portable and not. Decide before you buy where the unit lives, what it has to cross to get there, and whether stairs are involved.
10 ms against 20 ms, and what that actually covers
The DELTA 3 Ultra Plus is rated to transfer in 10 ms or less, the SOLIX F3000 in 20; both are ratings, not measurements. Neither is slow, and for a fridge, a router, and a few lamps both handovers are invisible. The EcoFlow simply holds the more conservative margin, which is the one you want when what's plugged in is a desktop mid-render or a NAS mid-write rather than a lamp.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here.
There's no decibel figure for the F3000
EcoFlow rates the DELTA 3 Ultra Plus at 30 dB. Anker publishes no equivalent for the F3000, so on paper there's nothing to compare and nothing to hold anyone to. Read it as a missing number rather than a bad one, but if this unit is going in a bedroom or a home office, it's a gap worth knowing about before the purchase rather than after.

Worth knowing
Anker's consumer-electronics reputation for no-hassle replacement is why a lot of people shortlist SOLIX in the first place, and it's the part that has drifted: recent reports describe AI-driven first-line support and complicated hazmat return logistics for units this heavy. Firmware updates have also removed features without notice. None of that appears on a spec sheet, and all of it appears the week something goes wrong.
Analyst note
EcoFlow runs the deeper bench, with a dozen-plus models, the largest community in the category, and a wider expansion ecosystem than the SOLIX line offers. Anker brings the stronger parent-brand reputation and generally better dollars per watt-hour. Both support organizations draw mixed marks, and neither brand record is a good enough reason on its own to pick one of these two boxes over the other.

EcoFlow DELTA 3 Ultra Plus
Everything we have on the Ultra Plus comes from review desks rather than from people who've owned one through a winterA0, so treat the record as short-term testing on a recent unit. What that testing agrees on is the fan: quiet even under heavy load, close to what EcoFlow's own DELTA Pro Ultra manages, and unobtrusive during sustained drawA1A2A13. Build quality gets the same reception, described as substantial rather than fragile, rated for a 0.2 m drop and for overnight dewA8A14.
Two findings are worth knowing before you wire anything up. The unit sheds its 30A port first when you overload itA3, which is useful context if that circuit feeds an RV inlet and you're wondering why it went dark while the wall outlets kept humming. It also doesn't throttle its output to match input while charging through the wallA4, and one reviewer pulled the plug mid-use without seeing a dip or a shut-offA6. Another ran a full eight-hour remote workday on it, laptop and desktop workstation and monitors, and finished with 40% leftA5. One reviewer's gripe is the screen, which washes out in direct sunA7.

Anker SOLIX F3000
The F3000's record is also review-desk rather than long-haul ownerB0, though it has been on sale long enough that the hands-on testing has some teeth to it. The consistent theme is restraint. Measured idle draw came in at 20.5W with only the inverter live, under Anker's own 25W figure, so it can sit on standby for days without eating itselfB4, and it's quiet under heavy load in a way earlier SOLIX units weren'tB5. Recharging is quick: about two hours from a standard AC outlet, or about one with the TT-30 cableB3.
The complaints are physical and specific. The four AC outlets sit close enough together that one fat adapter blocks its neighborsB6, and the AC charging plug is now a proprietary twist-lock that barely clears the chassis when the unit stands uprightB7. Output has real-world edges the spec sheet doesn't mention: it ran a Vitamix that pops 20A breakers elsewhereB9 but shut itself down when an air fryer and a microwave were asked to work at the same timeB2, and a Cybertruck charging attempt failed outright because the outlet isn't groundedB10.

Who Should Buy Which
Buy the DELTA 3 Ultra Plus if youβ¦
- βYou're buying the house's blackout box and it lives in a closet or a garage that isn't on the same floor as the fridge. The lighter unit is the one you'll still be willing to move on the third outage of the year.
- βYou charge laptops straight off the box. 140W over USB-C against the Anker's 100W tops a laptop from the port without waking the inverter.
- βSomething fussy is on the other end of the cord, a desktop mid-render or a NAS mid-write. The rated 10 ms handover is the wider margin, and a reviewer pulled the wall plug during use without seeing a dipA6.
Buy the SOLIX F3000 if youβ¦
- βYour panels are already past 1,600W, or that array is genuinely the plan. 2,400W of input is the one advantage on this page that $99 can't buy back.
- βThe unit rolls to where it's used and never climbs a flight of stairs. Wheels and a telescoping handle make 91.5 lb a non-event on flat groundB1B8, and you keep the money.
- βIt'll sit on standby for days at a time. A measured 20.5W idle draw with the inverter awake, under Anker's own 25W figure, is a tested number, not a claimed oneB4.
If neither fits
Anyone trying to run a van or a small cabin off a single box should skip both. The daily van-life load we model is 4,685Wh and either unit covers only about 56% of it, so you're shopping for a base plus at least one expansion battery, or for a bigger platform entirely. Price the whole stack before you fall for either head unit.
The Bottom Line
Take the DELTA 3 Ultra Plus. Same battery, same inverter, same surge as the F3000, and the $99 premium buys 17.2 fewer pounds to lift, half the rated transfer time, a noise figure someone is willing to print, and 140W over USB-C to the Anker's 100W. Nothing on the Anker's side of the ledger closes that except one thing.
That one thing is the solar ceiling, and it's a genuine argument for a genuine minority. If your array is already bigger than 1,600W, buy the F3000, save the money, and don't look back. If your recharge plan involves a wall outlet, the extra input is a number on a box you'll never touch, and you'd be paying for it in pounds every time you move it.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Anker SOLIX F3000 worth picking over the EcoFlow DELTA 3 Ultra Plus to save $99?
Only if you're charging from a big solar array. The F3000 takes 2,400W of solar to the EcoFlow's 1,600W, and that's the one advantage the $99 can't buy back. On the other differences, the DELTA 3 Ultra Plus is ahead: 17.2 lb lighter, a rated 10 ms transfer instead of 20, a published 30 dB noise rating, and 140W over USB-C to the Anker's 100W.
Which one recharges faster?
From the sun, the F3000. Its 2,400W ceiling can move 3,072Wh in about 1.3 hours at full rate against about 1.9 hours for the EcoFlow's 1,600W, assuming you own enough panels and get enough sun to hit either number. From the wall, reviewers measured the F3000 at roughly two hours for a full charge, or about one hour using its TT-30 cable; we don't have a comparable measured AC figure for the Ultra Plus.
Can I run two big kitchen appliances at once on either of these?
Plan on no. Both rate 3,600W continuous and 7,200W surge, and testing still found the F3000 shutting itself off when an air fryer and a microwave were asked to run together. The F3000 started a Vitamix that pops 20A breakers elsewhere, and the EcoFlow carries the same 7,200W surge rating on paper. Stagger the heavy appliances instead of stacking them, on either unit.
Which is quieter, the DELTA 3 Ultra Plus or the SOLIX F3000?
EcoFlow rates the DELTA 3 Ultra Plus at 30 dB. Anker doesn't publish a decibel figure for the F3000, so there's no like-for-like number to compare. Reviewers call both quiet under heavy load, with the EcoFlow compared favorably with EcoFlow's own DELTA 2 Max and DELTA Pro Ultra and the F3000 described as a marked improvement on earlier SOLIX models.
Will either one run a CPAP all night?
Both, without breathing hard. A CPAP night runs about 320Wh, roughly 12% of either unit's usable capacity, which is about eight nights on a single charge. Capacity isn't the constraint at this size, so if the machine sits beside your bed, judge them on fan behavior instead, where only the EcoFlow comes with a published rating.
