EcoFlow DELTA 3 Plus vs Anker SOLIX C1000X Gen 2
Same 1,024Wh on both, but the DELTA costs less, expands, and nearly doubles the solar input — so this comes down to how you refill and whether you plan to grow.

Spec deltas
The DELTA 3 Plus and the C1000X Gen 2 both carry 1,024Wh and both switch over in 10ms, so the battery and the backup speed are a wash. The gaps open up around them. The DELTA takes 1,000W of solar to the Anker's 600W, it accepts an expansion battery where the Anker is sealed, and it costs $100 less.
The Anker is not without a reply. It is the lighter box at 24.9 pounds against 27, it sustains 2,000W continuous to the DELTA's 1,800W, and its USB-C pushes 140W to the DELTA's 100W. If you lift the unit often and charge laptops fast, those are real.
But the DELTA's edges are the ones that decide outages and off-grid days, and it is cheaper on top of them. The single thing giving a careful buyer pause is the DELTA's fans, which reviewers say misbehave at low loadA1 — a genuine flaw, and probably a temporary one.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
solar input
For anyone recharging off panels instead of a wall, that 400W gap is the difference between topping up over a lunch break and babysitting the charge into the afternoon — and it is the DELTA that also costs less to own.

Why it mattersSolar-first campers and preppers should take the DELTA; the extra input is the spec that shortens their day.
continuous output
A hard-starting load — a fridge compressor, a pump, a power tool — cares about the surge ceiling, and the DELTA's 3,600W gives it more room to catch that spike; a long steady load like a microwave cares about continuous watts, where the Anker's 2,000W pulls ahead.
DELTA 3 Plus: 1,800W continuous, 3,600W surgeC1000X Gen 2: 2,000W continuous, 3,000W surge
Why it mattersMatch the box to your worst load: startup surges point to the DELTA, sustained high draw points to the Anker.
The DELTA's flaw is at least visible and likely patchableA4, while the Anker's silence means you are trusting an unrated fan — the DELTA at least publishes a 30 dB figure its own reviewers say it does not always honorA1.
DELTA 3 Plus fans activate even under low load and cycle erraticallyA1reviewers expect EcoFlow can fix it in firmwareA4Anker publishes no noise figure for the C1000X Gen 2
Why it mattersIf the unit runs two feet from your pillow, wait for a firmware note on the DELTA or a published spec on the Anker before you commit either to the nightstand.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: DELTA is both cheaper up front and cheaper per lifetime kWh.
cost / lifetime kWh
Two 1,024Wh batteries, both good for 4,000 cycles, both delivering about 4,096 kWh before they retire — so lifetime value falls to the sticker. The DELTA 3 Plus lands at $0.17 per lifetime kWh against the Anker's $0.20, and it got there while costing $100 less up front.
You are paying more for the Anker and pulling the same energy out the far end. The premium has to be justified by weight and output, because it is not coming back in kilowatt-hours.
Growth Path
Selected because: DELTA expands, Anker is sealed — the core flexibility split.
solar input
The DELTA accepts an expansion battery; the Anker is sealed at 1,024Wh. That is the fork in the road for anyone whose needs are not fixed. If a longer outage or a bigger trip is plausibly in your future, the DELTA can grow into it while the Anker asks you to buy a second unit instead.
If 1,024Wh is genuinely all you will ever draw, the port is dead weight and you can ignore it. The DELTA just keeps the option open, and the Anker forecloses it.
What the Specs Don't Tell You
Selected because: Surge headroom favors DELTA; Anker's undisclosed noise is the counter-flag.
The surge flag favors the DELTA and the noise flag favors nobody. The DELTA carries 3,600W of surge over its 1,800W rating, twice the cushion, where the Anker's 3,000W over 2,000W is a slimmer one-and-a-half times — real margin when a compressor or pump slams the inverter at startup.
The countervailing catch is that Anker never published a noise figure for the C1000X Gen 2, so the one number a light sleeper cares about is simply absent from the page.
Portability & Form Factor
Selected because: The Anker's genuine wins: lighter body, more continuous output, faster USB-C.
weight
Here is where the Anker earns its keep. It is the lighter box at 24.9 pounds against 27, it sustains 2,000W continuous to the DELTA's 1,800W, and its USB-C tops out at 140W against 100W. If you charge laptops fast and lift the unit in and out of a truck often, it is the friendlier travel companion.
None of that reverses the price and solar gaps, but it is a genuine trade rather than a rounding error. The Anker is the better carry; the DELTA is the better value and the better refill.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP is about 40W for eight hours, so both cover the night with room to spare and capacity decides nothing. Fan noise would — but SOLIX C1000X Gen 2 doesn't publish a figure, so there's nothing to hold it to. Buy on price, weight, and whether you can live with a fan you haven't heard.

Either unit
Both handle game day easily. Since capacity isn't the deciding factor, weight is: at 24.9 lbs the SOLIX C1000X Gen 2 is the one you'll be glad you brought. Fan noise under load is worth a listen too — it's audible in the lulls between songs.

Conclusion
July 18, 2026
Verdict: the EcoFlow DELTA 3 Plus
Take the DELTA 3 Plus for most uses. It costs $100 less than the C1000X Gen 2, works out cheaper per lifetime kWh, accepts 1,000W of solar to the Anker's 600W, and can add an expansion battery the sealed Anker cannot. The Anker's real answers are a lighter 24.9-pound body, 200W more continuous output, and a faster app-gated wall recharge, which suit a specific buyer. The one caveat that keeps this at moderate confidence is the DELTA's documented fan quirk — reviewers catch the fans spinning up at low load and cycling erraticallyA1 — though it reads like a firmware problem EcoFlow can fixA4.

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 Plus rates 4.3/5 (61st percentile of 24 Everyday-class units), and SOLIX C1000X Gen 2 rates 3.7/5 (22nd percentile of 24 Everyday-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
SOLIX C1000X Gen 2: Fixed Capacity
The SOLIX C1000X Gen 2 is sealed at 1,024Wh — a complete unit, and already larger than the DELTA 3 Plus's 1,024Wh. By contrast the DELTA 3 Plus can add expansion batteries, but that only pulls ahead if you'd grow past 1,024Wh.
Surge headroom favors the DELTA
The DELTA 3 Plus holds twice its continuous rating in surge (3,600W over 1,800W); the Anker holds one and a half times (3,000W over 2,000W). When a fridge or pump slams the inverter at startup, the bigger cushion is the one less likely to trip. It is the DELTA's clearest hardware win.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here.
Anker left the noise line blank
EcoFlow publishes 30 dB for the DELTA, even if its fans do not always live up to it, while Anker prints no noise figure for the C1000X Gen 2. On the unit you might run beside your bed, one at least gives you a number to argue with.

Analyst note
Both units have similar long-term ownership costs ($0.18/kWh vs $0.2/kWh). The price difference is what you see on the sticker — neither is a hidden bargain or rip-off. One thing to know reading the table: both carry the same 4,000-cycle rating, so the lifetime rows are sticker price and capacity in disguise — the wear horizon is identical and decides nothing here.

Unique strength
Parent-brand trust from Anker's consumer-electronics business and some of the strongest dollar-per-watt-hour value in the category.
Worth knowing
SOLIX-specific support quality has trended down from Anker's historically excellent standard, and firmware updates have removed features without much warning.
Analyst note
EcoFlow is the safer pick if you want ecosystem depth and fast solar; Anker is the value play if you just want a well-priced 1kWh box and will not lean on support. Neither brand's service story is spotless right now, so where you buy matters nearly as much as which you buy.
Growth path

EXPANDABLESupports EcoFlow expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 1,024Wh.
Accepts up to 1,000W of solar. Enough for a serious multi-panel array.
Generous port selection supports complex multi-device setups.
Expansion batteries are EcoFlow-specific. You're investing in the EcoFlow ecosystem.
SOLIX C1000X Gen 2
FIXED CAPACITYFixed at 1,024Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 600W of solar. Suitable for a 1-2 panel setup.

Analyst note
The SOLIX C1000X Gen 2 is sealed at 1,024Wh, which is fine if that covers you. The DELTA 3 Plus starts at 1,024Wh and can grow beyond it with EcoFlow expansion batteries — though at this size expansion means longer runtimes on the same loads, not a path to home backup. More hours, not more house.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3 Plus
The DELTA 3 Plus reviews beautifully everywhere except one place: the fans. Testers praise the fast recharge and the sub-10ms UPS switchover for keeping gear alive through a cutA3, but the recurring, specific complaint is that the fans spin up even under light load and cycle on and off erratically, which undercuts its billing as a quiet backupA1. A couple of reviewers go further and note the erratic cycling can let it run warm under heavy loadsA2.
The saving grace is that this reads like a software problem, not a hardware one — reviewers expect EcoFlow can calm the fan logic in a firmware update, as it has done for earlier unitsA4. If that patch lands, the DELTA's one real weakness mostly closes.
“Otherwise well-designed, with very fast recharge times and a seamless sub-10ms UPS switchover for uninterrupted power.”

Anker SOLIX C1000X Gen 2
Set against the DELTA's fan drama, the C1000X Gen 2's fan story is calmer but not silent: near-silent when it is loafing under about 200W, then loud enough under heavy draw that you would not want it in the bedroomB1B2. Buyers also like that it shows up nearly charged and refills fast at the wall, which matters when the window to top up is shortB4.
Two honest caveats. This exact SKU is new enough that most of the field commentary is paraphrased from retailer review pages rather than long-term ownership, so read it as directional. And unlike the DELTA, it cannot take an expansion battery at all — the capacity you buy is the capacity you keepB10.
“Near-silent under light loads — rated 0 to 20dB under 200W — quiet enough for an office or bedroom when it's just sitting idle or trickle-charging.”

Who Should Buy Which
Buy the DELTA 3 Plus if you…
- →The solar-first camper or prepper. 1,000W of input tops this off in about an hour of good sun, and if your needs grow you can add battery — two doors the Anker keeps shut.
- →Anyone starting hard-surging gear. The 3,600W surge ceiling gives compressors and pumps more room to spike than the Anker's 3,000W, and it costs less while doing it.
Buy the SOLIX C1000X Gen 2 if you…
- →The buyer who wants the most continuous output in the lightest box. At 24.9 pounds and 2,000W it is a couple of pounds lighter and 200W stronger than the DELTA for sustained loads, with quicker 140W USB-C for laptops.
- →Someone who refills at the wall on a deadline and will enable UltraFlash to do it fastB5, and who does not need the fan to vanish at night.
If neither fits
If your real goal is a full day of fridge-and-lights backup, both of these 1,024Wh units come up short — you want the 2,000Wh-plus class for that. And if a whisper-quiet bedroom unit is the whole point, hold off: the DELTA's fans are under a documented cloudA1 and Anker will not tell you the C1000X's number.
The Bottom Line
Take the DELTA 3 Plus. It costs $100 less to buy, less to own over its life, doubles the solar input to 1,000W, and can grow when the Anker cannot — a stack of advantages the C1000X Gen 2 answers mainly with two fewer pounds and 200W more continuous output. For the off-grid and grow-into-it buyer, that is not close.
The one honest hesitation is the DELTA's fans, which reviewers catch spinning up when they should be stillA1. It looks like a firmware problem EcoFlow can fixA4, and if a silent nightstand is your priority you might wait for that patch. For everyone charging off the sun or planning to expand, the DELTA is the better box today.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow DELTA 3 Plus or the Anker C1000X Gen 2 better for solar charging?
The DELTA, clearly. It accepts 1,000W of solar input to the Anker's 600W, so from empty it refills roughly a day's capacity in about an hour of strong sun while the Anker takes longer. If you charge off panels more than off the wall, that gap is the whole ballgame.
Which one is quieter, the DELTA 3 Plus or the C1000X Gen 2?
Neither is a safe bet for a silent room, oddly. The DELTA is rated 30 dB but reviewers report its fans spin up even at low load and cycle erratically, and Anker never published a noise number for the C1000X Gen 2 at all. If quiet is non-negotiable, wait for a DELTA firmware fix or a published Anker spec.
Why does the DELTA 3 Plus cost less but score higher?
Because it costs less to own and does more of what our score rewards. It is cheaper up front at $699, takes an expansion battery, and carries more surge headroom, so it edges the sealed, pricier Anker on value and flexibility. The Anker's answers are lighter weight and higher continuous output, which the score weighs but not enough to flip it here.
Can the Anker C1000X Gen 2 expand like the DELTA?
No. The C1000X Gen 2 is sealed at 1,024Wh with no expansion port, while the DELTA 3 Plus accepts add-on batteries. If future growth matters, that is a point for the DELTA; if 1,024Wh covers you for good, it is moot.
