Head-to-head test
Anker SOLIX C800 vs Anker SOLIX S2000
Anker SOLIX C800 vs Anker SOLIX S2000: Anker has stopped selling the C800, so only one of these two can still be bought. The S2000 brings 2,010Wh against 768Wh, a 3,000W peak against 1,600W, and 10,000 rated cycles against 3,000. Buy the S2000 unless you already own a C800, in which case keep it as the lighter box for weekends.

Spec deltas
Anker has stopped selling the SOLIX C800, so half of this comparison has no price and no buy button. The successor in Anker's own range is the SOLIX C800X. That leaves the live recommendation here with a single candidate, and it leaves the rest of the page doing a narrower job: the C800's specs are still accurate, and plenty of people own one or are looking at leftover retailer stock.
The S2000 isn't a half step up from it. It holds 2,010Wh against the C800's 768Wh, peaks at 3,000W against 1,600W, and is rated for 10,000 cycles against 3,000. Its UPS mode is rated no worse than 10ms where the C800's is rated no worse than 20ms, and it accepts 400W of solar against 300W. Capacity, surge and cycle life all moved in the same direction, which is unusual and makes the comparison short.
The C800 does win one row, and it's the row buyers underrate. At 23.8 lbs it's about twelve pounds lighter than the 35.7 lb S2000, and testers at two separate outlets independently complained that the S2000 has no comfortable one-hand carryB7B8. The other honest note cuts the same way: the S2000's win on the eight-hour outage is 63Wh of headroom on a 1,645Wh load, which is minutes, not hours.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Resistive loads never test that. A heater overran the C800's rating for 25 minutesA8 and a 1,000W coffee maker ran 42 minutes flat outA3, because a heating element draws what it draws and nothing more at the moment you switch it on. Motors are the reason surge exists, and what starts a motor is the absolute ceiling rather than the ratio. A full-size fridge spiking to 700-800W on startupA11 fits under 1,600W with room left. A second motor joining it, or a compressor-driven air conditioner, is where 1,600W runs out and 3,000W doesn't.
SOLIX S2000: 1,500W rated, 3,000W published peak, a 2x ratioSOLIX C800: 1,200W rated, 1,600W published peak, a 1.3x ratioFridge and AC compressors briefly draw 2-3x their rated wattage at startupA tester ran a 1,500W space heater on the C800 for 25 minutes before it throttledA8
Why it mattersIf the heaviest thing you'll plug in has a compressor or a pump, the S2000's ceiling is the argument. If it's a kettle, a heater or a coffee maker, both units handled that class and availability decides instead.
rated cycles
Both units outlive their identical five-year terms by years even at daily cycling, so longevity here isn't a warranty question. 8.2 years of nightly use is a real service life, 27.4 is longer than most people keep a vehicle, and at the end of either the pack is still delivering about 80%. Cycle life only becomes a purchase reason if you actually cycle: at six weekends a year, neither pack is ever going to be the part that fails.
C800: 768Wh per cycle, 3,000 cycles rated, roughly 2,304 kWh over its rated lifeS2000: 2,010Wh per cycle, 10,000 cycles rated, roughly 20,096 kWh over its rated lifeCycled daily, that's 8.2 years against 27.4At the cycle limit the pack drops to about 80% of original capacity rather than dying
Why it mattersDaily cyclers, van dwellers and off-grid cabins should read this as one S2000 standing in for three C800s. If the thing lives in a closet between holidays, skip the row entirely and decide on capacity.
Read those two rows as the same warning. 1,645Wh over eight hours averages about 206W, so the S2000's 63Wh of margin is roughly another 18 minutes. A nine-hour outage isn't a different scenario, it's the same one with the lights going out at the end. The C800's 17Wh miss makes the point from the other side: trim one small appliance out of the afternoon and it finishes the tailgate its nameplate says it should.
Tailgate Party needs 670Wh; the C800's 768Wh nameplate clears it, its 653Wh usable figure doesn't, a 17Wh gap8-Hour Blackout needs 1,645Wh; the S2000 clears it with 63Wh of its 1,708Wh usable to spareEvery unit here is derated by a flat 85% usable allowance, not a per-unit measurement
Why it mattersIf your real load sits within a few percent of either unit's usable figure, buy the larger station rather than trusting the last 5%. Neither of these takes an expansion battery, so the margin you buy is the margin you keep.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: 768Wh against 2,010Wh decides three of the six scenarios below before any other spec gets a vote.
continuous output
An eight-hour outage asks for 1,645Wh, and the C800 has 653Wh to give once the flat 85% usable allowance is applied. That's about 40% of the way in, and then it stops. Every runtime row on this page has the same shape: the S2000 isn't better at stretching a charge, it simply starts with 2,010Wh where the C800 starts with 768Wh, and careful load management doesn't close a gap that size.
Charge speed is where the small pack fights back. Testers clocked a full C800 recharge in 58 minutes on a 600W adapterA9, which turns it into a unit you refill between uses rather than rationA15. The S2000 answers on its own terms: independent hands-on testing measured 80% in about 1.2 hours and full in roughly 1.7 hours from a 20-amp household circuitB5. Neither of these is the slow one. Only one of them holds enough that the speed stops mattering.
Your Life, Your Pick
Selected because: The interesting rows are the close ones: the C800 misses the tailgate by 17Wh, and the S2000 clears the eight-hour outage by 63Wh.
Four of these six rows go the same way, and the two worth a second look are the close ones. The C800 comes up 17Wh short on the Tailgate Party, close enough that its 768Wh nameplate actually clears the 670Wh load and only the flat usable allowance tips it under. The S2000 covers the same afternoon with 1,038Wh spare, which is the difference between a unit at its limit and a unit doing light work.
The two rows nobody wins are the honest ones. Van Life Daily wants 4,685Wh and the S2000 is still 2,977Wh short at about 36% covered, which is a larger station's job rather than a choice between these two. Weekend Camping is closer than it reads: the S2000 gets 81% of the way through 2,100Wh and misses by 392Wh, and at its 400W solar input ceiling that shortfall is roughly an hour of strong sun. The C800's 1,447Wh gap at 300W would need closer to five hours of it, which is most of a good solar day spent refilling rather than camping.
What the Specs Don't Tell You
Selected because: The S2000's 3,000W peak against the C800's 1,600W is the one difference that decides whether a motor starts at all.
rated cycles
Read the surge row carefully, because both units publish the same kind of figure and they aren't close. 3,000W peak against 1,600W, and more usefully 1,500W of headroom above continuous rating against 400W. The ratio the spec sheets prefer to quote, 2x against 1.3x, is the flattering version. A compressor doesn't know the ratio. It draws what it draws in the instant it starts, and the ceiling is what it runs into.
The UPS row is softer than it looks. Both figures are ratings rather than measurements, no worse than 10ms for the S2000 and no worse than 20ms for the C800, which is a promise about a ceiling and not a stopwatch result. Two independent testers watched connected office gear ride through a simulated outage on the S2000 without an interruptionB9B10. Routers and most electronics ride through either class. The case for caring is a desktop with unsaved work on it, and even then you're choosing between two promises.
Portability & Form Factor
Selected because: 23.8 lbs against 35.7 lbs is the only row the C800 wins, and it's the one people underrate until the stairs.
weight
Twelve pounds is the C800's whole case and it isn't a small one. 23.8 lbs is a one-hand grab out of a trunk; 35.7 lbs is a two-hand lift you plan around, and testers at two separate outlets both said the S2000 wants a second handle before you take it up stairsB7B8. One tester dropped a C800 thirty inches onto gravel and found scuffing and nothing worseA1. Neither unit carries an IP rating, so both want a cover when the weather turnsA2.
Two smaller things travel with the boxes. The C800's record carries two USB-A ports against the S2000's one, and a 12V car socket that the S2000's record leaves blank rather than at zero, so treat that as unknown and check Anker's spec sheet if a 12V fridge is the plan. Both carry five AC outlets and 100W USB-C. And if you're walking any real distance with either, the advice a tester gave about the lighter of the two still holds: that's a job for a power bank, not a power stationA12.

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 the full 2,100Wh weekend. The C800 stops 1,447Wh short at about 31% of the list, and the S2000 gets 81% of the way there and misses by 392Wh. That gap is small enough to be a solar problem rather than a capacity problem: at the S2000's 400W input ceiling, 392Wh is about an hour of strong sun, while the C800 would need closer to five hours at 300W. Bring panels or shorten the list.

SOLIX S2000
The S2000 finishes this one and the C800 doesn't, but look at the margin before you relax. 1,645Wh over eight hours averages about 206W, and the S2000 has 63Wh of its 1,708Wh usable left at the end, so call it another 18 minutes. It clears the row. It doesn't clear it comfortably. The C800 stops 992Wh short, roughly 40% of the way in, which isn't a thin pass but a different class of unit.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
Capacity is a formality here. A 40W machine for eight hours is 320Wh and both units cover that several times over, so the useful question is how many nights rather than whether one night works. The S2000's 1,708Wh usable is roughly five nights of it, the C800's 653Wh roughly two, which is the difference between riding out an outage and watching the sky on day three. On noise, both makers publish a rating rather than a measurement of a 40W draw, and they don't publish it the same way, so look for hands-on reports before either box sleeps beside your head.

SOLIX S2000
The SOLIX C800 doesn't finish — 653Wh usable against the 910Wh this needs leaves it 257Wh short, about 72% of the scenario covered. The SOLIX S2000 covers it with 798Wh to spare.

SOLIX S2000
The C800 misses this by 17Wh, which is a rounding error dressed up as a failure. The 670Wh load sits under its 768Wh nameplate and only the flat usable allowance every unit here gets pushes it under, so drop one small appliance from the afternoon and it finishes. The S2000 covers the same load with 1,038Wh to spare, which is the more useful fact if the afternoon runs long or somebody plugs in one more thing.

Conclusion
September 19, 2026
Verdict: the SOLIX S2000, on Power Score margin
Take the SOLIX S2000, at $700. It's the only one of these two Anker still sells, and it would have been the pick regardless: 2,010Wh against 768Wh, a 3,000W peak against 1,600W, and 10,000 rated cycles against 3,000. The 8-Hour Blackout row settles it. The S2000 finishes with 63Wh of usable capacity to spare while the C800 stops 992Wh short, about 40% of the way through. The one reason to leave this page is sizing: if 768Wh was the plan and 2,010Wh is more station than your evening needs, the live unit in that class is Anker's SOLIX C800X, not the S2000.

Power Score
Computed from 14 published spec dimensions, weighted per use-case bench. Higher is better; a unit must meet a bench's minimum threshold to be rated.
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, SOLIX C800 rates 4.1/5 (47th percentile of 20 Compact-class units), and SOLIX S2000 rates 5.0/5 (99th percentile of 26 Large-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.
SOLIX C800: 45dB Published
45dB is about as loud as a running refrigerator. The SOLIX S2000 is rated 30dB — lower, but the two ratings need not describe the same operating regime even within one maker's own range, so the two figures are not a like-for-like gap. For most people, fan noise around 45dB and up is where sleep starts to suffer.
Surge: 3,000W Against 1,600W
The S2000 peaks at 3,000W over a 1,500W continuous rating, so it holds 1,500W of headroom. The C800 peaks at 1,600W over 1,200W, so it holds 400W. Ratios are how a spec sheet flatters an inverter, 2x against 1.3x, but a motor doesn't know the ratio. It draws what it draws at the instant it starts, and the absolute ceiling is what it runs into. The C800's 1,600W is genuinely enough for a lot of that class, so check the startup draw of your heaviest motor against 1,600W rather than assuming it trips. Two motors starting near each other is where the difference stops being academic.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The SOLIX S2000 is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The SOLIX C800 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: Same Five Years, One Live Clock
Both units carry the same 5-year Anker term, so on paper coverage isn't a tiebreaker. The difference is which clock can still be started. A warranty covers a purchase, and there's no new C800 purchase left to cover: a unit bought while it was still in the range keeps whatever remains of its five years, and that's the whole of what the term means here now. Read this row as a full five years of cover on the S2000, and the remainder on a C800 you already own.
Battery Lifespan in Real Years
The SOLIX S2000 is rated for 10,000 cycles vs 3,000. In real life: at daily use, that's 27.4 vs 8.2 years. At weekend use (twice a week), it's 96 vs 29 years. One caution reading years across different sizes: a cycle is 2,010Wh on the SOLIX S2000 and 768Wh on the SOLIX C800, so count lifetime energy — roughly 20,096 kWh against 2,304 kWh over the rated life. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.

Analyst note
The SOLIX C800 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 SOLIX S2000 works out at $0.03/kWh over its rated life. If you already own the SOLIX C800, the hardware comparison still holds: over its rated life the SOLIX C800 delivers about 2,304 kWh and the SOLIX S2000 about 20,096 kWh.
Growth path
SOLIX C800
FIXED CAPACITYFixed at 768Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 300W of solar. Limited to a single portable panel.
Adequate ports for most setups, but heavy users may want a power strip.
SOLIX S2000
FIXED CAPACITYFixed at 2,010Wh — a sealed, complete system rather than a starting point. There's no expansion port, so that figure is the ceiling: check it against your longest unplugged stretch before you buy.
Accepts up to 400W of solar. Suitable for a 1-2 panel setup.
Adequate ports for most setups, but heavy users may want a power strip.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
Growth only counts if you can still buy in, and the SOLIX C800 is no longer sold (Anker points owners to the SOLIX C800X). That leaves the SOLIX S2000: it is sealed at 2,010Wh, so buy the size that covers you now. The SOLIX C800's fixed 768Wh still matters if you already own one, but it isn't a reason to pick it over the SOLIX S2000.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
Anker SOLIX C800
Field data on the plain C800 is thin, and the honest reason is that there are no owner threads to draw on. A site-limited Reddit query came back with nothing, so what exists is review-bench testing rather than long-term ownership, and several of those sites contradict each other on basics like price and warranty length, which points to templated content rather than independent testingA0. Nobody has published a six-months-later report, a cold-weather result, or an idle-drain figure for this exact modelA0.
What the bench testing does cover, it covers usefully. A 1,000W coffee maker ran 42 minutes straightA3 and a 1,500W space heater ran 25 minutes past the unit's own 1,200W rating before it throttledA8, while the same reviewers cautioned that a full-size fridge at 700-800W startup plus other essentials isn't a load it holds for longA11. One tester dropped it thirty inches from a tailgate onto gravel and got scuffsA1, and two separately flagged the weight as more than you want to carry far on footA4A12. The recharge is the most-repeated finding: 58 minutes to full on a 600W adapter, faster than the rivals they compared it againstA9A15.

Anker SOLIX S2000
The S2000 launched in June 2026, so everything below is weeks old rather than months, and there are no longevity reports on it yetB0. Two outlets ran genuine hands-on tests rather than repeating the press kit, and they agree on the quiet: fans spin up only under heavy load or the fastest charging mode, and the unit is effectively silent at idleB1B2. Both measured standby draw in single digits, roughly 2W with outputs off and about 6W with AC enabled and nothing plugged inB3B4, which is the difference between a unit you can leave armed for a storm and one you have to keep topping up.
On the jobs people buy it for, one tester ran a fridge and assorted kitchen gadgets for over 60 hours on a chargeB12, and both watched office equipment ride through a simulated grid failure without a flickerB9B10. The complaints are real but small: two reviewers independently wanted a proper second handle for stairsB7B8, and one noticed a warm-electronics smell within a few feet of the unit during the first hours of sustained AC load, which faded after a day and raised no safety concernB6. The app drew praise for clear navigation and sensible defaultsB11.
“Fans only spin up under real load or fast charging, and at idle the unit is silent.”

“Powered a 1500W space heater (surpassing its 1200W rating) for 25 minutes before throttling—unexpectedly robust for its size.”

“Achieved a full charge in 58 minutes using a 600W AC adapter (matching Anker's claim), while competitors like the Jackery 700 take 2+ hours.”

“The 1200W output won't run a full-size refrigerator (700-800W startup) plus other essentials for long.”

“At 23.15 lbs (10.5 kg), this is too heavy for carrying far on foot. For hiking, a smaller, lighter power bank under 5 lbs is a better fit.”

“Charged fully, disconnected from wall power with AC output enabled and no loads attached, then monitored for 10 hours: state of charge dropped only to 99%, implying about 2W average draw — matching Anker's spec.”

Who Should Buy Which
Buy the SOLIX C800 if you…
- →You already own a C800: nothing on this page is a reason to replace it. 3,000 cycles is 8.2 years of nightly use, longer than most people hold a power station, and the 58-minute rechargeA9A15 covers a weekend better than 768Wh suggests it should.
- →You wanted the 768Wh class rather than 2 kWh: the live unit in that size is Anker's own SOLIX C800X. Look there instead of talking yourself into two and a half times the capacity you originally costed out.
Buy the SOLIX S2000 if you…
- →The household that wants lights, a router and the fridge through a full evening outage. That load is 1,645Wh, and the S2000 is the one of these two that reaches the end of it.
- →Anyone whose heaviest appliance has a compressor in it. 3,000W of peak covers a 700-800W fridge startupA11 with room for something else kicking in at the same moment, which 1,600W does not.
- →CPAP users planning for more than one night. A 40W machine for eight hours is 320Wh, so 1,708Wh of usable capacity is roughly five nights before you need sun or a wall socket.
- →Daily cyclers. 10,000 rated cycles against 3,000 is the row that separates a unit you run down every night from one you use on holidays.
If neither fits
If your day looks like the Van Life Daily row, 4,685Wh, close this tab. The S2000 is still 2,977Wh short of that, and the answer is a larger station or a station plus a real roof array rather than either of these. Same if you're carrying power on foot: at 23.8 lbs even the lighter of the two is too heavy for that, and a sub-five-pound power bank is the category you actually wantA12.
The Bottom Line
Buy the SOLIX S2000. Anker stopped selling the C800, so it's the only live candidate here, and the specs say it would have won the argument anyway: 2,010Wh, a 3,000W peak, 10,000 rated cycles. The one row the C800 takes is the twelve pounds, and twelve pounds is worth real money right up to the moment an eight-hour outage asks for 1,645Wh and your unit has 653Wh to give.
If 2 kWh is more station than your evenings need, the honest next click isn't the other unit on this page, it's Anker's SOLIX C800X. Everyone else: the S2000, and don't plan your loads down to its last watt.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Anker SOLIX C800 discontinued?
Yes. It left Anker's range in August 2026, and the successor in Anker's own lineup is the SOLIX C800X, which is where to look if the 768Wh class is what you wanted. This comparison stays up because the C800's specs are still accurate for the people who own one and because leftover retailer stock turns up. The recommendation, though, has exactly one live candidate.
What is the Anker SOLIX S2000's surge rating?
1,500W continuous and 3,000W peak, a 2x ratio. That's 1,500W of headroom above its own rating, against 400W on the C800, which is rated 1,200W continuous and 1,600W peak. Surge is what a motor pulls in the instant it starts, so the absolute 3,000W ceiling matters more than the ratio does.
Will the Anker SOLIX S2000 run a refrigerator through a blackout?
Yes, with one margin worth knowing. Our 8-Hour Blackout load is 1,645Wh and the S2000 covers it with 63Wh of usable capacity left, so it finishes but not comfortably. Startup isn't the obstacle: a full-size fridge spiking to 700-800W sits well under the 3,000W peak, and one tester ran a fridge plus kitchen gadgets for over 60 hours on a single charge.
Can either one run a CPAP all night?
Both, several times over. A 40W machine for eight hours is 320Wh against 653Wh of usable capacity on the C800 and 1,708Wh on the S2000, so figure roughly two nights and five nights per charge. Noise is the harder question, because both makers publish a rating rather than a measurement and not on the same basis. Testers found the S2000 silent at idle with fans only under heavy load or fast charging, and the C800 quiet below 500W with a mild hum at maximum.
Which is lighter, the SOLIX C800 or the SOLIX S2000?
The C800, at 23.8 lbs against 35.7 lbs, a difference of about twelve pounds. It's the one row the C800 wins outright, and reviewers at two outlets flagged the S2000's lack of a comfortable one-hand carry. If either unit is going up and down stairs regularly, that gap is the part you'll feel.
