Head-to-head test
EcoFlow DELTA Pro vs Anker SOLIX F2000
The F2000's 2,800W surge sits just 400W above its 2,400W continuous, while the DELTA Pro holds 7,200W in reserve — so for $400 more the Pro starts the heavy compressor loads the Anker chokes on, and costs less per lifetime kWh besides.

Spec deltas
The EcoFlow DELTA Pro costs $1,399 and the Anker SOLIX F2000 costs $999, and the $400 between them buys more than a bigger battery. The Pro holds 3,600Wh against 2,048, pushes 3,600W continuous against 2,400, and — the number that decides hard loads — surges to 7,200W against the F2000's 2,800.
That surge gap is the one to sit with. The F2000's 2,800W ceiling is only 400W above its 2,400W continuous rating, which is thin margin for the half-second a fridge or AC compressor spikes at startup. The DELTA Pro carries double its continuous rating in reserve, so it brings heavy motors up cleanly where the Anker can stall.
None of that makes the F2000 a weak unit. It's $400 cheaper, 32 lbs lighter, and the wheels-and-handle design is the single most-praised thing about it. This comes down to whether your loads reach past what the Anker can hold and start — and for a lot of buyers, they don't.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
A fridge or AC compressor draws 2-3x its running wattage for the instant it starts, and that instant is exactly where thin surge headroom fails. The F2000 may run a load it can't start; the Pro's 7,200W ceiling is built for the spike.
F2000: 2,400W continuous, 2,800W surgeDELTA Pro: 3,600W continuous, 7,200W surge
Why it mattersIf the buy is backup for a fridge, a well pump, or a window AC, the surge number rules it — and it points at the DELTA Pro.
rated cycles
Spread each price across that energy and the pricier unit is actually cheaper to own: $0.11 per lifetime kWh against $0.16. The F2000's lower sticker doesn't survive the division.
DELTA Pro: 3,600Wh for $1,399, 3,500 cyclesF2000: 2,048Wh for $999, 3,000 cycles
Why it mattersBuyers weighing the $400 should know the Pro repays it in delivered energy; the F2000 wins on price today, not over its life.
weight
For a unit that moves — campsite, RV bay, trunk — 32 lbs and better wheels is a real, daily advantage the Pro's extra capacity can't hand back. But it's a portability win, not a power win.
F2000: 67.2 lbs on wheels and a retractable handleDELTA Pro: 99 lbs
Why it mattersIf the unit travels more than it backs up the house, the F2000's weight and wheels are the reason to take it over the heavier Pro.
The specific dimensions that decide these two units — everything else is a tie.
PowerScore Breakdown
Selected because: The 2,800W vs 7,200W surge gap is the sharpest, most decision-relevant difference on the page.
overall power score
The Pro scores 5,483 against the F2000's 3,837, and the surge rating is where that gap earns its keep. The F2000 runs 2,400W continuous with a 2,800W surge — a 400W cushion — while the DELTA Pro backs its 3,600W continuous with 7,200W of surge.
That cushion is the whole game for motor loads. A running fridge draws maybe 150W but spikes past 800W to start; a window AC is worse. The Pro absorbs those spikes without noticing. The F2000's narrow margin means a load it can run steadily is a load it might refuse to start, which is the failure mode that ends a blackout early.
Lifetime Value
Selected because: The Pro's higher sticker is actually the lower cost per lifetime kWh.
cost / lifetime kWh
The F2000 is $400 cheaper up front, and by warranty-year math it stays cheaper: $200 a year of coverage against the Pro's $280, both on 5-year terms. That's the honest case for the Anker.
Stretch the horizon to delivered energy and it flips. The Pro's larger pack and higher cycle count add up to 12,600 lifetime kWh against 6,144, so it works out to $0.11 per kWh over its life against the F2000's $0.16. You pay more on day one for the unit that costs less per unit of power you actually use.
Portability & Form Factor
Selected because: The F2000's real win — 32 lbs lighter and the wheels owners love.
weight
The F2000 is 67.2 lbs against the Pro's 99, and it's the rare unit whose portability is its headline feature. The 4.72-inch wheels and retractable handle draw more owner praise than any spec, and for good reason — it rolls like heavy luggage instead of being carried.
The Pro also has wheels, but at 99 lbs they're damage control, not a selling point. If your unit lives on the move, the 32-lb gap and the better-loved wheels are a genuine reason to give up some capacity for the Anker.
Your Life, Your Pick
Selected because: The capacity gap decides weekend camping; everyday loads both clear.
Both units clear the everyday loads — an 8-hour blackout, a CPAP night, a remote workday, a tailgate — the Pro simply with more in reserve each time. The line they split on is a full weekend camp at about 2,100Wh, which the F2000 can't quite cover at 121% of its capacity while the Pro handles it at 69%.
Full daily van life near 4,685Wh is beyond both alone. So the practical read: if your day tops out around a blackout or a workday, either serves; once it reaches a real off-grid weekend, only the Pro finishes it on its own.
Growth Path
Selected because: Both expand; the Pro's higher solar ceiling breaks the tie off-grid.
solar input
Both units expand, so neither is a dead end. The tiebreaker is refill speed: the DELTA Pro accepts 1,600W of solar against the F2000's 1,000W, so a grown-out setup tops off faster from the same sun.
For an off-grid buyer adding panels and batteries over time, that higher intake compounds — every added kWh still refills in a reasonable window. It's the one place the Pro's platform keeps paying after the purchase.

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
DELTA Pro
The SOLIX F2000 runs out of juice. It only has 1,741Wh usable, but this scenario needs 2,100Wh. The DELTA Pro covers it and still has 64h of phone charging left over.

LOAD Phone Charger 15W×6h · LED Lights 40W×8h · Box Fan 75W×14h · CPAP Machine 40W×16h
SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
DELTA Pro
Both survive, but the DELTA Pro finishes at just 54% used. That's enough reserve for a second blackout night. The SOLIX F2000 at 94% leaves little margin if the outage runs longer than expected. In storm-prone areas, that remaining capacity is insurance.

LOAD Fridge 150W×8h · Router + Modem 20W×8h · LED Lights (4 bulbs) 40W×6h · Phone Charger 15W×3h
SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
Both are wildly overqualified for CPAP. You're using 18% or less. Save your money and buy whichever is cheaper; the extra capacity is completely wasted on a 40W overnight load. Put the savings toward a second battery for multi-night trips.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
DELTA Pro
The DELTA Pro gives you a comfortable buffer at 30%. Enough to work late, join extra video calls, or charge a second device without worry. The SOLIX F2000 at 52% works but leaves less room for the unexpected. For daily remote work, that peace of mind matters.

Tailgate Party
Game day power for the crew
DELTA Pro
Both handle game day, and the DELTA Pro does it with more in reserve — 22% used against 38%. Tailgating is a light load, so that headroom counts for less here than the 32 lbs you'll actually carry across the parking lot.

Conclusion
July 16, 2026
Verdict: the DELTA Pro, on Power Score margin
The DELTA Pro is the more capable machine and, over its life, the cheaper one: 3,600Wh against the F2000's 2,048, 3,600W continuous against 2,400, and a 7,200W surge against 2,800 — and $0.11 per lifetime kWh against $0.16. That surge figure is the real separator. The F2000's 2,800W ceiling is only 400W above its continuous rating, tight headroom for starting a fridge or AC compressor, where the Pro's doubles its continuous. The catch, and it's a fair one, is that the F2000 costs $400 less, weighs 32 lbs less, and rolls on wheels owners genuinely love. For a buyer whose loads stay under 2,048Wh and never start a big motor, the F2000 is the smarter, lighter, cheaper pick. For anyone backing up real household loads or planning to grow, the DELTA Pro's capacity and surge win 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 Pro rates 3.9/5 (33rd percentile of 16 Home Backup-class units), and SOLIX F2000 rates 3.5/5 (13th percentile of 25 Large-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Weight Reality Check
Neither unit is grab-and-go. The SOLIX F2000 (67.2 lbs) is manageable solo but heavier than a large checked suitcase. The DELTA Pro (99 lbs) is noticeably heavier. That's a 32 lb difference.
DELTA Pro: 60dB Under Load
60dB is about as loud as a normal conversation. If you're running a CPAP or sleeping near this unit, the fan noise may be noticeable. Most people find anything above 45dB disruptive for sleep.
Surge Power: Inverter Quality Indicator
The DELTA Pro has a 2× surge-to-continuous ratio vs the SOLIX F2000's 1.2×. A higher ratio (≥2×) means the inverter handles motor startup surges better. That's critical for fridges, AC compressors, and power tools that briefly draw 2-3× their rated wattage. The SOLIX F2000 may trip when starting these appliances even though its continuous wattage looks sufficient.
Warranty Value Comparison
The SOLIX F2000 gives you 5.6 years of warranty per $1,000 spent, vs the DELTA Pro's 3.1 years. That's 1.8× more coverage per dollar. An underrated factor if you're keeping this unit for years.
SOLIX F2000: Noise Level Not Disclosed
The DELTA Pro publishes its noise level (60dB), but the SOLIX F2000 doesn't. Brands that don't disclose noise specs often have louder units. If noise matters to you (CPAP users, apartment dwellers), this is worth investigating before buying.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA Pro
The DELTA Pro is a wheeled unit by necessity, and owners treat the wheels and telescoping handle as the thing that makes its 99 lbs livable — they work well on flat, smooth ground, though uneven terrain still calls for a cartA2. It's a different portability story than the Anker's: managed weight, not light weight.
Where it's earned its name is endurance. Long treated as a gold standard for home backup, it's sized for high-draw appliances and full expansionA1, and testers who ran it across months of overnight outages report it powering essentials at once without troubleA3. The one recurring knock: above 2,000W the fans put out a high-pitched whine that carries in a quiet room, though it's civil at lighter loadsA4.
“Long regarded as a gold standard for home backup — designed for high-draw appliances and full-scale battery expansion, running home essentials like a fridge, lighting, and a space heater through outages.”

Anker SOLIX F2000
The F2000's standout in owner reports is exactly what the spec sheet undersells: how easy it is to move. The 4.72-inch wheels and retractable EasyTow handle are the top reason reviewers say owners picked it over similar-spec rivals — it lugs around far more easily than its battery weight suggestsB1. For the loads RVers actually run — fridge, CPAP, lights, fans, internet, a TV, small kitchen gear — reviewers call it quiet, capable, and fast to deployB3.
The app draws praise for monitoring and customizing power use over Wi-Fi and Bluetooth, and a meaningful number of owners report Anker stepping in proactively with firmware fixes or replacementsB2. Underneath it's the same LFP reliability as Anker's other stations, rated past 3,000 cycles for years of backup or off-grid useB4.
“It'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 — most positive reviews cite the wheels and telescoping handle as a top reason owners chose it over similar-spec competitors.”

Who Should Buy Which
Buy the DELTA Pro if you…
- →You're backing up real household loads — a fridge, a well pump, a window AC — where the 7,200W surge starts motors the F2000's 2,800W ceiling can stall on.
- →Your off-grid days run past 2kWh, or you plan to grow the system, where 3,600Wh and 1,600W of solar intake keep you ahead.
Buy the SOLIX F2000 if you…
- →The unit travels — RV bay, campsite, trunk — and 32 lbs less on wheels owners rave about beats capacity you won't use.
- →Your loads stay under 2,048Wh and never start a big compressor, and you'd rather keep the $400 than buy headroom you won't reach.
If neither fits
Full-time van life near 4,685Wh a day outruns both on their own. If that's the target, start with a larger unit built around heavy expansion and high solar rather than maxing out a 2-3kWh base from day one.
The Bottom Line
Take the DELTA Pro if you're backing up a home. Its 7,200W surge starts the fridge-and-pump loads the F2000's 2,800W ceiling can stall on, it holds 1,552Wh more, and it costs less per lifetime kWh despite the higher sticker. For household backup, that's the unit.
The F2000 is the right call for a different buyer: someone who moves the unit constantly, runs loads under 2,048Wh, and would rather have 32 fewer pounds on genuinely great wheels and $400 back. Match the unit to whether it travels or defends the house, and the choice is clean.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the DELTA Pro worth $400 more than the Anker SOLIX F2000?
It depends on your loads, but for household backup, yes. The Pro holds 3,600Wh against 2,048, and its 7,200W surge starts heavy motors the F2000's 2,800W ceiling can stall on. It's also cheaper per lifetime kWh, $0.11 against $0.16. If your loads are light and portability matters more, the F2000 saves you $400 and 32 lbs.
Why does the F2000's surge rating matter so much?
Because starting a load and running it are different jobs. The F2000's 2,800W surge is only 400W above its 2,400W continuous rating, and a fridge or AC compressor spikes 2-3x its running draw to start. That narrow margin means the F2000 can refuse to start a load it would otherwise run fine — where the DELTA Pro's 7,200W surge has room to spare.
Which is easier to move around?
The F2000, clearly. It's 67.2 lbs against the Pro's 99, and its 4.72-inch wheels and retractable handle are the feature owners praise most. Both have wheels, but on the Anker they're a selling point and on the 99-lb Pro they're a necessity.
Do both last a long time?
Yes, both use LFP chemistry with long cycle lives — 3,500 cycles for the Pro and 3,000 for the F2000, both under a 5-year warranty. The Pro delivers more total lifetime energy simply because it holds more, which is why it lands cheaper per lifetime kWh despite the higher price.
