Anker SOLIX C1000 vs BLUETTI AC240P
The AC240P wins on paper and the C1000 wins on price: spend the extra $1,013 only if you need more than 1kWh in one box, 2,400W of output, or an IP65 shell the Anker simply can't match.

Spec deltas
The SOLIX C1000 costs $449 and the AC240P costs $1,462, and for most buyers that gap decides it before capacity enters the room. These aren't the same class of machine: the AC240P is a 1,843Wh, IP65-rugged, 72 lb unit, and the C1000 is a 1,056Wh, 28.4 lb one you can lift in a hand. On paper the AC240P is the better box. The real question is whether you need the premium it's charging.
That premium buys three specific things. About 75% more capacity, enough to cover a work-from-home day and land within about 5% of a full 8-hour blackout the C1000 can't finish. A weatherproof IP65 shell, proven in a rainstorm and on a saltwater sailboatB2, that the C1000 has no answer to. And more output and solar: 2,400W against 1,800W, and 1,200W of panels against 600W. Nearly everything else on the page tilts the other way.
Cheaper to buy, cheaper per lifetime kilowatt-hour, far lighter, more warranty per dollar: those columns are the C1000's, and for the loads people usually put on a 1kWh station they're what you'll feel. Take the C1000 unless you specifically need the capacity band above 1,600Wh, the 2,400W output, or a unit that lives out in the weather. Then, and only then, the AC240P earns its price.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
cost / lifetime kWh
You are not buying cheaper power with the AC240P; you are buying more of it in one box, at a premium paid twice, once on the sticker and again on every kilowatt-hour. That math only turns in the AC240P's favor if you genuinely need more than 1kWh in a single unit. If 1,056Wh covers your night, the C1000 is both cheaper to buy and cheaper to run.
SOLIX C1000: $449 for 1,056WhAC240P: $1,462 for 1,843WhLifetime cost: C1000 $0.14 per kWh vs AC240P $0.23 per kWh
Why it mattersThe 1kWh buyer should take the C1000 and pocket the difference; the AC240P's premium buys capacity, not value.
Capacity
The AC240P's extra capacity does nothing below roughly 900Wh, where both units cover a CPAP, a tailgate, and a workday alike, and the C1000's 12Wh miss is a single phone charge. It earns its price only in the band above that: the long blackout, the load that runs past 1,600Wh. Push to a 2,100Wh weekend or a 4,685Wh van day and neither finishes, so the headroom helps inside one specific window and nowhere else.
C1000 usable about 898Wh (1,056Wh after a flat 15% derate)AC240P usable about 1,567Wh (1,843Wh after the same derate)8-hour blackout needs 1,645Wh; remote workday needs 910Wh
Why it mattersSize the purchase to your worst realistic night: near 900Wh, the C1000 is enough; near 1,600Wh, the AC240P's capacity is worth paying for; past 4,000Wh, buy neither.
weight
Weight and weatherproofing are the same coin here. The AC240P is heavy in large part because it is built to sit outside and take weather; the C1000 is light in part because it is not. On a boat, a job site, or a truck bed, the heavy weatherproof unit is exactly right and the weight is just the cost of the armor. Shuttled in and out of a trunk every weekend and parked indoors, that extra bulk is dead weight and the IP65 never gets invoked.
C1000: 28.4 lbsAC240P: 72 lbsAC240P is IP65-rated; the C1000 carries no IP rating
Why it mattersDecide where the unit will physically live before you weigh capacity: a stationary outdoor life points to the AC240P, a carried indoor life points hard at the 28.4 lb C1000.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The C1000 is $449 to the AC240P's $1,462 and still delivers energy cheaper over its life ($0.14 vs $0.23 per lifetime kWh), so the money question starts and largely ends here.
cost / lifetime kWh
Start with the money, because it mostly ends here too. The C1000 delivers energy at $0.14 per lifetime kilowatt-hour against the AC240P's $0.23, so the cheaper unit is also the cheaper one to run, which isn't how it usually goes. The AC240P does hand you more total energy across its life, about 6,451 kWh to the C1000's 3,168, because it carries more capacity and a slightly higher cycle rating. But you buy that energy at a premium twice over: once on the sticker, and again on every kilowatt-hour you pull from it.
So the AC240P isn't the frugal choice dressed up as the expensive one. It's the expensive one, honestly priced for more capacity. If your needs fit inside 1,056Wh, nothing in the lifetime math argues for spending more.
Your Life, Your Pick
Selected because: The AC240P's 1,843Wh covers a remote workday and comes within 78Wh of an 8-hour blackout the 1,056Wh C1000 can't finish, which is where the premium either earns out or doesn't.
Capacity is the AC240P's entire argument, and it shows up in a narrow band. A remote workday wants 910Wh: the AC240P covers it with 657Wh to spare, while the C1000 lands 12Wh under after the flat 15% usable derate. Its 1,056Wh nameplate would clear it, so one skipped phone charge finishes the day, and that 12Wh is not a real defeat.
The gap that matters is the long night. An 8-hour blackout wants 1,645Wh; the AC240P gets within 78Wh, and the C1000 covers a bit past halfway and stops. Push higher, to a 2,100Wh weekend or a 4,685Wh van day, and neither unit finishes, so the AC240P's headroom buys you one thing: the evening that runs between roughly 900 and 1,600 watt-hours. Below it, both cope. Above it, both fold.
Portability & Form Factor
Selected because: 28.4 lbs against 72 lbs is the difference between a one-hand grab and a two-person lift, and it decides every carry-and-camp use before capacity does.
weight
Weight is where these two feel least alike. The C1000 is a 28.4 lb one-hand lift, the kind you sling into a trunk without thinking. The AC240P is 72 lbs: a two-hands, bent-knees, flat-ground-only lift, heavier than a large checked suitcase, and a genuine two-person job up stairs.
Much of that mass is the sealed IP65 enclosure, so the weight and the weatherproofing arrive together. If the unit lives in one spot and takes weather, you carry it rarely and the toughness pays off. If it rides in and out of a vehicle every weekend and sleeps indoors, the extra bulk is the first spec you'll resent, and the IP65 never gets used. Match the unit to how often it actually moves.
What the Specs Don't Tell You
Selected because: The AC240P adds a published 45dB figure, a ≤15ms UPS rating and a 6-year warranty; the C1000 publishes no noise number at all, which is worth knowing before a bedroom buy.
rated cycles
The gotchas that fire here almost all point one way: they're the premium the AC240P is charging for. It lists a 45dB noise floor (a best-case number, not a measurement under load), rates its UPS switchover at ≤15ms against the C1000's ≤20ms, and carries a 6-year warranty to the C1000's 5. On coverage, more is more; just note that the C1000's lower price is what makes its warranty look generous per dollar, not a longer term.
The one gotcha pointing back at the C1000 is what it doesn't say: it publishes no noise figure at all. That's a data gap, not a verdict. Field reports fill part of it, with owners saying the fans spin up under fast charging or heavy load, close to a desktop fan, then go nearly silent below about 500WA1. So a CPAP or a light overnight load is a non-issue for either unit; the noise question only bites if you're fast-charging near the limit in a room where someone is trying to sleep.

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 unit covers this scenario's 2,100Wh: the SOLIX C1000 comes up 1,202Wh short (about 43% covered), the AC240P 533Wh (75%). Treat this as partial cover — enough for the essentials in it, not the whole list.
Battery budget usedlower = more headroom
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
Neither unit
This scenario needs 1,645Wh and neither unit quite finishes it. The AC240P lands within 5% of it — close enough that trimming one appliance, or accepting a shorter evening, gets you there on the day.
Battery budget usedlower = more headroom
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
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 C1000 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.
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
AC240P
The SOLIX C1000 comes up just short — it needs 910Wh and has 898Wh usable, a 12Wh gap (its nameplate 1,056Wh actually clears this — the flat 15% conversion allowance is what tips it under). Trim that much — one small appliance's worth across the day — and it finishes. The AC240P covers it outright with 657Wh to spare.
Battery budget usedlower = more headroom
LOAD Laptop 60W×8h · External Monitor 30W×8h · Router + Modem 20W×8h · Phone Charger 15W×2h
SCN-05 · 4 hours · needs 670Wh
Tailgate Party
Game day power for the crew
AC240P
Both handle game day; the AC240P keeps more in reserve (43% used vs 75%). Tailgating is a light load, though, so the number you'll feel is weight: 28.4 lbs for the SOLIX C1000 against 72 lbs for the AC240P, from the trunk to the setup spot.
Battery budget usedlower = more headroom
LOAD Blender 400W×0.5h · LED TV (55") 80W×4h · Bluetooth Speaker 15W×4h · Phone Charger (×3) 45W×2h

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Neither unit covers this scenario's 4,685Wh: the SOLIX C1000 comes up 3,787Wh short (about 19% covered), the AC240P 3,118Wh (33%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

Conclusion
August 30, 2026
Verdict: the Anker SOLIX C1000
Take the SOLIX C1000. It's roughly a third of the AC240P's price, it delivers energy more cheaply over its life, and at 28.4 lbs against 72 it's the one you'll actually carry. For the loads people cross-shopping these usually run, a CPAP, a tailgate, a work-from-home day, its 1,056Wh either covers the night or lands close enough to finish by trimming one appliance. The AC240P is the better machine on paper, with 1,843Wh, a 2,400W inverter, and IP65 weatherproofing the C1000 can't match, and it's the right buy if you truly need more than 1kWh in one box, run 2,000W-plus loads, or put the unit out in the weather. Short of those three, you're paying triple for headroom you won't use.

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, SOLIX C1000 rates 4.7/5 (81st percentile of 27 Everyday-class units), and AC240P rates 3.9/5 (35th percentile of 27 Everyday-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.
72 lbs buys weatherproofing, not just watt-hours
72 lbs is a two-hands, bent-knees, flat-ground-only lift; the C1000, at 28.4 lbs, is a one-hand grab. Much of the AC240P's weight is the sealed IP65 enclosure and the larger battery, so you're carrying the toughness whether or not you use it. If the unit sits in one place, that's a fair trade. If it moves every weekend, it's the first thing you'll resent lifting.
AC240P: 45dB Published
45dB is about as loud as a running refrigerator. It is BLUETTI's own rating rather than a reading on a shared bench — makers differ on whether they quote a best case or a figure under load, so treat it as a starting point rather than what you would hear at a bedside. For most people, fan noise around 45dB and up is where sleep starts to suffer.
UPS Switchover: ≤15ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The AC240P is rated ≤15ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. The SOLIX C1000 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.
Warranty: 6 Years vs 5
The AC240P is covered for 6 years against the SOLIX C1000's 5 years. The cheaper SOLIX C1000 does buy more warranty per dollar (11.1 years per $1,000 against 4.1), but that is a statement about price, not about coverage — if a fault appears in year 6, only one of these is still covered. An underrated factor if you're keeping this unit for years.
The C1000's one missing number
The AC240P lists 45dB; the C1000 lists nothing. Read that as a hole in the data, not proof the Anker is loud, and remember 45dB is a best-case floor rather than a measurement under load, so it isn't a clean yardstick either. It matters in one place: a bedroom or a CPAP nightstand. If that's where this unit is headed, resolve the missing number first and try to hear one before you buy.

Brand trust
Anker
Ecosystem
7-8 SOLIX portable power stations across C-series (compact) and F-series (flagship), plus the X1 home energy system
Support
US-based, and historically famous for no-questions replacements. Recent SOLIX reports are softer: AI-driven first-line responses and awkward hazmat return logistics on heavy units. Call it trending down from a high bar, not a collapse.
Community
Moderate — active Reddit (r/Anker, r/AnkerSOLIXCommunity) and growing. Benefits from Anker's massive consumer electronics brand awareness.
App experience
Rated 4.5/5 iOS (~1,100 ratings) · 4.3/5 Android
Unique strength
Anker's consumer-electronics trust behind the battery, and some of the best cost-per-watt-hour in its class; the C1000 is one of the stronger value buys in Anker's own lineup.
Worth knowing
Firmware updates have quietly removed features before, and the expansion ecosystem is smaller than EcoFlow's.
BLUETTI
Ecosystem
One of the broadest lineups — 15-20+ models from budget (AC2A) to flagship portable (Apex 300, 2764.8Wh). Includes specialized products: vehicle solar hubs, sodium-ion cold-weather units, and balcony storage systems.
Support
The most inconsistent in the category. Some buyers get quick, clean service; others get email runarounds on China time and offers of a discount on a new unit in place of a repair. Buying direct from BLUETTI rather than a third party measurably improves the odds.
Community
Active and growing — Reddit r/bluetti has a dedicated community. Second-largest after EcoFlow in engagement.
App experience
Rated 4.5/5 iOS and Android — tied for best app experience in the category. V3.0 UI redesign was well-received.
Unique strength
Among the best capacity-per-dollar on the market, the widest lineup in the space, and here specifically a genuinely rugged IP65 design most rivals don't offer.
Worth knowing
Older or discontinued models can become hard to repair, so keep the direct-purchase paper trail if you buy.
Analyst note
Both apps are top of the class (4.5 out of 5), so the real brand gap is support. Anker's is easing down from an excellent standard; BLUETTI's is a coin-flip you can weight in your favor by buying direct. On the pricier unit that risk carries more weight, one more quiet point for the C1000, and a firm reason to buy the AC240P straight from BLUETTI if you choose it.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
Anker SOLIX C1000
Field data is unusually deep for a unit this size, including a real one-year data point. The steady complaint is fan noise: the fans spin up audibly during fast charging or heavy output near the limit, close to a desktop fan at speed, and settle to nearly silent below about 500WA1. One reviewer ran theirs for over a year and still measured roughly 97% of original capacity; in a 30-day home-office UPS test it rode out seven brief outages with no shutdowns and no lost dataA2.
Reviewers credit it for the fundamentals, fast AC recharge, a strong inverter for short bursts, practical size, and app monitoring that's actually usefulA3, and for handling nearly any household appliance short of central AC and an electric dryerA4. One note on sourcing: some 2026 coverage is of the C1000 Gen 2 rather than the base unit, but the fan, reliability, and charging behavior carry across bothA0.
“One reviewer used their unit for over a year with zero issues and minimal battery degradation — about 97% of original capacity. In a 30-day home-office UPS test it handled 7 brief outages with no equipment shutdowns or data loss.”

BLUETTI AC240P
The AC240P's field story is weatherproofing, and it holds up. Reviewers left one out in a six-hour rainstorm with water beading off and the inside bone dry, and ran another through constant saltwater spray on a sailboat with no moisture intrusion after a wipe-downB2. The catch is real: the IP65 rating only applies with every port cover closed, so the moment a cable is plugged in the seal is broken and it shouldn't be run in the rain that wayB1.
Beyond the ruggedness it reads as the premium end of BLUETTI's line, with LFP cells, a fast charge that reaches most of full quickly, and expansion to a multi-kWh bankB4; the 1,843Wh capacity is the main reason to choose it over the 1,536Wh standard AC240B3. The evidence here is review-driven rather than long-term-owner, so treat the ruggedness as well-documented and the multi-year longevity as promising but not yet proven by timeB0.
“IP65 water- and dust-resistant, but the protection applies only when all port covers are closed; using it with cables plugged in compromises the rating, and it shouldn't be used in the rain that way.”

- →You carry it. In and out of a trunk, up basement stairs, across a campsite: 28.4 lbs is a one-hand grab and 72 lbs is not.
- →You want the lowest cost per lifetime kilowatt-hour in this matchup, and the most warranty per dollar.
Buy the AC240P if you…
- →Your worst realistic night runs past 1,600Wh, a long blackout powering more than the essentials, or you run 2,000W-plus loads the C1000's 1,800W inverter won't start.
- →The unit lives outdoors: a boat deck, an open job site, a truck bed. IP65 weatherproofing is the one advantage here money can't add to the C1000B2.
- →You want to grow off-grid: 1,200W of solar input and a higher expansion ceiling refill and scale faster than the C1000's 600W.
If neither fits
If your daily draw runs to the 4,685Wh of a real van-life setup, or you want one box to cover a 2,100Wh weekend outright, neither of these finishes the job. That's the moment to size up to a larger station, an EcoFlow DELTA Pro or one of BLUETTI's bigger AC units, rather than force one of these into a role it isn't built for.
The Bottom Line
Take the C1000. It's roughly a third of the AC240P's price, it's cheaper per lifetime kilowatt-hour, and at 28.4 lbs it's the one that actually leaves the garage. For a CPAP, a workday, or a tailgate, its 1,056Wh either covers the night outright or gets there by trimming a single appliance. That settles it for most.
The AC240P isn't the loser so much as the specialist. It's the more capable box, with more capacity, more output, and an IP65 shell that shrugs off rain the C1000 can't touch, and if the unit lives outdoors or your worst night runs past 1,600Wh, it's worth every dollar of the premium. Just don't pay three times over for weatherproofing you'll only ever use indoors. Decide where the box will sit, and the winner picks itself.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Anker SOLIX C1000 or BLUETTI AC240P better value?
The C1000, clearly. At $449 it's roughly a third the price of the AC240P's $1,462, and it delivers energy more cheaply over its lifetime as well. The AC240P gives you more total capacity and more lifetime energy, but you pay a premium for it both up front and per kilowatt-hour.
Why is the BLUETTI AC240P so much more expensive?
You're paying for roughly 75% more capacity (1,843Wh against 1,056Wh), a 2,400W inverter against the C1000's 1,800W, and an IP65 weatherproof shell the C1000 doesn't have. It's also a 72 lb unit against 28.4 lbs. Whether that premium is worth it comes down to one question: do you actually need more than 1kWh, more output, or weatherproofing? If not, the C1000 does the same everyday jobs for far less.
Can the Anker SOLIX C1000 run my house during a power outage?
For a modest evening, largely yes. After the standard usable derate it delivers about 898Wh, enough to keep a CPAP, phones, a laptop, lights, and a fridge going in stretches, but short of a full 1,645Wh 8-hour blackout, which it covers a little past halfway. The AC240P gets within 78Wh of that same night. Neither one runs central air or an electric dryer: the C1000 tops out at 1,800W and the AC240P at 2,400W, and those appliances draw well past both.
Is the BLUETTI AC240P actually waterproof?
It's IP65-rated, dust-tight and protected against low-pressure water jets, and it earns it in the field: reviewers left one out in a six-hour rainstorm and ran another through saltwater spray on a sailboat with no water getting in. The important caveat is that the rating only holds with every port cover closed. Plug a cable in and the seal is broken, so it isn't meant to run out in the rain that way. The C1000 carries no IP rating at all, so for genuine weather exposure this is the AC240P's clearest edge.
Is the Anker C1000 or BLUETTI AC240P quieter?
There's no clean answer, because Anker doesn't publish a noise figure for the C1000 and BLUETTI's 45dB for the AC240P is a best-case floor rather than a measured-under-load number. What field reports do say is that the C1000's fans spin up under fast charging or heavy load, like a desktop fan, then go nearly silent below about 500W. For a CPAP or a light overnight load, both are quiet; noise only becomes a real factor if you're fast-charging or running near the limit near someone who's sleeping.
