No longer sold
Anker has replaced the C800 line with the C800X — at $449.99 it currently ships with a 100W solar panel included, so the newer unit costs less than the C800 did.
SOLIX C800X · $449.99Spec deltas
The bigger Anker is the cheaper Anker. The SOLIX C1000 Gen 2 lists at $530 with 1,024Wh; the SOLIX C800 lists at $599 with 768Wh. You pay $69 less and get 256Wh more battery, 800W more inverter, 1,000 more charge cycles and twice the solar input.
The C800 wins one line on the entire spec sheet. It weighs 23.8 lbs to the C1000 Gen 2's 24.9. That is the whole case for spending more.
Same brand, same 5-year warranty, same chemistry, so this isn't a build argument or a support argument. It's size against price, and both of those point one direction. There is exactly one sentence on this page that argues for the C800, it's about fan noise, and we'll get to it.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
rated cycles
Divide the price by that energy and it's $0.13 a kilowatt-hour against $0.26. The C800's electricity costs double, and it charged a $69 premium up front for the privilege. No feature bolted onto a 768Wh box closes a gap like that, because the gap isn't a feature. It's cells and cycles.
SOLIX C1000 Gen 2: $530, 1,024Wh, 4,000 cyclesSOLIX C800: $599, 768Wh, 3,000 cyclesRated lifetime energy: 4,096 kWh vs 2,304 kWh
Why it mattersIf you came here looking for the budget pick, the budget pick is the bigger unit.
continuous output
What you run into first on the C800 is its ceiling, not its battery. A full-size fridge pulls 700-800W just to startB11, and once it's cycling there isn't much of the 1,200W left for a kettle, a microwave or a heater. The C1000 Gen 2's 2,000W continuous and 3,000W surge means you plug the second thing in without doing arithmetic first.

Why it mattersIf a fridge, a heater or anything with a compressor is why you're buying, the C800 is already out.
solar input
That gap only shows up when there's no wall, which is the exact situation you bought a power station for. On day three of an outage, or a week parked somewhere good, the C800 spends the best midday sun finishing what the Gen 2 wrapped up hours earlier. Reviewers already call its 300W middling for a unit this sizeB5.
C1000 Gen 2: 600W solar input feeding 1,024WhC800: 300W solar input feeding 768WhAC recharge is close: about 49 minutes for the Gen 2A1, 58 minutes for the C800 on a 600W adapterB9
Why it mattersAnyone buying panels alongside the unit can stop reading and take the C1000 Gen 2.
So the C1000 Gen 2 is the right call between these two and still isn't a weekend unit. A 2,100Wh camping weekend is 241% of what it delivers, and no amount of careful loading argues a ratio like that down. The buyers who should walk away from both are the ones sizing for two days rather than one.
Tailgate Party needs 670Wh: 77% of the C1000 Gen 2, 103% of the C800Remote Workday needs 910Wh: 105% of the C1000 Gen 2, 139% of the C800Weekend Camping needs 2,100Wh: 241% of the C1000 Gen 2, 322% of the C800
Why it mattersDay-scale loads: the C1000 Gen 2. Weekend-scale loads: neither, and shop the 2kWh class.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The cheaper unit is also the one with more cells and more cycles, and this is where that shows up: $0.13 per lifetime kilowatt-hour against $0.26.
cost / lifetime kWh
Two boxes, and the $69 cheaper one holds a third more energy and is rated for a third more cycles. Multiply those out and the C1000 Gen 2 delivers 4,096 kWh across its life to the C800's 2,304. Thirteen cents a kilowatt-hour against twenty-six. Read that once and you never need it again.
The same story in years: cycled every day, the Gen 2 has about 11 years in it against the C800's 8.2, and used only on weekends, 38.5 years against 28.8. Both carry an identical 5-year warranty, which means every year of that difference lands after the coverage ends and comes straight out of your pocket.
Runtime: Will It Power Your Gear?
Selected because: 1,024Wh behind a 2,000W inverter against 768Wh behind 1,200W decides which appliances you can actually plug in.
continuous output
Capacity decides how long something runs. The inverter decides whether it runs at all, and that's the larger half of this matchup: 2,000W continuous against 1,200W. A 1,500W space heater is a load the Gen 2 carries with headroomA3; on the C800, testers got 25 minutes before it throttledB8.
For the things people actually buy these for, a fridge and a router and a laptop, the C800 is fine right up to the moment two of them overlap. At 700-800W just to start a full-size fridgeB11, its 1,200W ceiling has little left over for the second appliance. That's the difference between a unit you plan around and one you plug into.
Your Life, Your Pick
Selected because: Only one of these finishes a 670Wh tailgate, and neither one finishes a 2,100Wh camping weekend.
A 320Wh CPAP night draws 37% of the C1000 Gen 2 and 49% of the C800, so capacity stops being the question and both units sail through. Everything above that splits them. A 670Wh tailgate is 77% of the Gen 2 and 103% of the C800, which is the most irritating way to fall short: the speaker dies while the game is still on.
Above a single day's loads they fail together. A 910Wh remote workday runs to 105% of the Gen 2 and 139% of the C800; a 2,100Wh camping weekend runs to 241% and 322%. Our pick misses that workday by a rounding error, and it's worth saying plainly. What the extra 256Wh buys is a bigger day, not a longer trip.
Growth Path
Selected because: One of them takes Anker expansion batteries. The other is sealed at 768Wh for good.
solar input
The C800 is sealed at 768Wh, and here that's a genuine strike rather than a technicality, because the C1000 Gen 2's starting capacity already exceeds the C800's ceiling before a single expansion battery is attached. Adding Anker expansion batteries later is a road the C800 simply doesn't have.
Whether the road matters depends on you. If 768Wh honestly covers your life, sealed is fine and expandability is a feature you'll never touch. But you aren't paying extra for it here, since the expandable one is also the cheaper one. The only way the sealed box wins this section is if you actively want less.
Portability & Form Factor
Selected because: The C800's only win on the whole spec sheet is 1.1 lbs, and it deserves an honest price.
weight
23.8 lbs against 24.9. That is the C800's entire advantage, a pound and a tenth, and it costs $69 and 256Wh to collect.
Neither of these is a hiking unit anyway. Reviewers call the C800 too heavy to carry any distance on foot and point you toward a power bank insteadB12, and that verdict doesn't change one pound higher up. Both are car-to-campsite, garage-to-kitchen boxes you lift once at each end of the trip.

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 Gen 2 comes up 1,230Wh short (about 41% covered), the SOLIX C800 1,447Wh (31%). Treat this as partial cover — enough for the essentials in it, not the whole list.

8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
Eight hours of the real list, fridge and lights and router and phones, comes to 1,645Wh, and neither unit covers it: 189% of what the C1000 Gen 2 delivers, 252% of the C800. So you triage. The C1000 Gen 2's 2,000W lets you keep the fridge and the router running together while you do it, where the C800's 1,200W makes you choose between them.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
SOLIX C1000 Gen 2
A 320Wh night is 37% of the C1000 Gen 2 and 49% of the C800, so both sleep through this with hours in reserve. The tiebreak is the thing humming on the nightstand: the C1000 Gen 2 is rated 35 dB against the C800's 45, and at a CPAP's gentle draw neither has any reason to spin up hard. Take the quieter rating and the deeper reserve.

Full work day off-grid without power anxiety
Neither unit
A 910Wh workday beats both of them, which is the honest answer here: 105% of what the C1000 Gen 2 delivers, 139% of the C800. One misses by a rounding error and the other misses by a lunch break. Either way you're topping up mid-afternoon, and only one of these takes 600W of solar to do it.

SOLIX C1000 Gen 2
670Wh of tailgate is 77% of the C1000 Gen 2 and 103% of the C800. Falling 3% short is the worst way to lose, because the afternoon doesn't end when the speaker does. The C1000 Gen 2 finishes the game with 23% of its delivered energy still in hand.

Neither unit covers this scenario's 4,685Wh: the SOLIX C1000 Gen 2 comes up 3,815Wh short (about 19% covered), the SOLIX C800 4,032Wh (14%). 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 2, 2026
Verdict: the SOLIX C1000 Gen 2
Take the SOLIX C1000 Gen 2. It's $530 against the C800's $599, and the $69 you keep comes with 256Wh more battery, an inverter that goes to 2,000W instead of 1,200W, 4,000 cycles instead of 3,000, and double the solar input. Across its rated life that works out to $0.13 per kilowatt-hour against $0.26, so the smaller unit's energy costs exactly twice as much. The C800's one advantage is 1.1 lbs, and nobody has ever noticed a pound and a tenth on the walk from the trunk to the campsite. The only thing that should stop you is scale: if your real load is a 2,100Wh camping weekend, both of these are the wrong size and you want a 2kWh-class unit instead.

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 C1000 Gen 2 rates 4.9/5 (96th percentile of 27 Everyday-class units), and SOLIX C800 rates 4.1/5 (47th percentile of 20 Compact-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
The C800 Is the Louder Box on Paper
Rated 45 dB under load against the C1000 Gen 2's 35 dB. Neither one is a generator, and neither will bother you while it tops up a phone. But in a tent, or a bedroom with the door shut, ten decibels is the difference between background and present. The quieter rating here belongs to the bigger, cheaper unit, which is the shape of this entire comparison.
768Wh, Permanently
The C800 takes no expansion batteries, so the number on the box is the number you live with for its whole life. That only becomes a problem because of what it's standing next to: the C1000 Gen 2 starts at 1,024Wh, more than the C800 holds full, and can still add more on top. Sealed is perfectly fine when the sealed unit is big enough. This one starts 256Wh behind.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The SOLIX C1000 Gen 2 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: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here.
Eleven Years or Eight
4,000 cycles against 3,000 stops being abstract the moment you convert it into a calendar: cycled daily, that's about 11 years for the C1000 Gen 2 and 8.2 for the C800. Used only on weekends, both outlast their own electronics at 38.5 years and 28.8. The warranty is 5 years either way, so those extra 1,000 cycles are value you get rather than coverage you're promised.
Full record above — the Test Desk pick is the SOLIX C1000 Gen 2.

Analyst note
The SOLIX C800 is sealed at 768Wh, which is fine if that covers you. The SOLIX C1000 Gen 2 starts at 1,024Wh and can grow beyond it with Anker 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.
Anker SOLIX C1000 Gen 2
Field material on the Gen 2 comes from review desks rather than long-term owners, and it's consistent: a full recharge in roughly 49 minutes, quicker than the original C1000's 58 to 80A1, and enough continuous output to run a 1,500W space heater with headroom leftA3. Reviewers broadly rate it the mid-size unit to beatA4.
The complaint is the fan, and since this is our pick, we'll own it. It's near-silent at low load, around 35 dB under 200W, then climbs to about 55 dB once you push past 1,000W or fast-charge itA2. If the plan is to refill it overnight in the room where you sleep, that's a real cost, not a footnote.
“Fast HyperFlash charging — a full recharge in roughly 49 minutes, noticeably quicker than the original C1000's ~58-80 minutes.”

Anker SOLIX C800
There's no owner community for the plain C800 to draw on, no forum threads and no long-term reports, so everything here is hands-on review-desk testing rather than crowd consensusB1B3B9. What that testing shows is a solid box: dropped 30 inches off a tailgate onto gravel with nothing worse than scuffingB1, a 1,000W coffee maker held for 42 minutes straightB3, and a full recharge in 58 minutes on a 600W adapterB9B15.
The same testing names the limits. There's no IP rating, so it wants a cover the moment weather shows upB2. Its 300W solar input is called middling for a unit this sizeB5. And the 1,200W inverter won't carry a full-size fridge plus other essentials for longB11. Weigh all of it accordingly: several of these sites contradict each other on the C800's basic price and warranty lengthB6B10, which reads more like templated coverage than sustained testing.
“We dropped it from a tailgate (30 inches) onto gravel—only minor scuffing, no damage.”

- →The blackout buyer with a full-size fridge in the kitchen. 2,000W continuous and 3,000W surge start a compressor and still leave room for the router, the modem and a couple of lamps, which is the entire job on night one.
- →Anyone buying panels with the unit. 600W of solar input against 300W means you refill during the good hours instead of chasing them until sundown.
- →The person whose needs are creeping upward. It starts at 1,024Wh and accepts Anker expansion batteries, so you add capacity later instead of re-buying the base unit.
- →The CPAP sleeper. A 320Wh night is 37% of it, it's rated 35 dB, and at that draw the fans have no reason to wake up before you do.
- →Anyone deciding on money alone. $530 against $599, and $0.13 a lifetime kilowatt-hour against $0.26. Both halves of the word cheap point the same way.
Buy the SOLIX C800 if you…
- →The buyer who has decided that 1.1 lbs is worth $69. That's the trade stated in full: 23.8 lbs instead of 24.9, and in exchange 768Wh instead of 1,024, 1,200W instead of 2,000, 3,000 cycles instead of 4,000.
- →The person who will only ever run a phone, a laptop and a string of lights, wants the smallest box in the room, and can find a C800 priced well under the C1000 Gen 2's $530. At $599 there is no load on this page where it wins.

If neither fits
If you're sizing for a weekend rather than a day, close this tab. A 2,100Wh camping weekend is 241% of what the larger of these two delivers and a 4,685Wh van-life day is 538% of it, and no loading discipline argues those ratios down. Shop the 2kWh-and-up class instead, where one unit covers the whole trip and you stop rationing on day two.
The Bottom Line
Take the SOLIX C1000 Gen 2. It's the cheaper box at $530, it holds a third more energy, its inverter reaches 2,000W instead of 1,200W, and every kilowatt-hour it will ever deliver costs $0.13 against the C800's $0.26. The C800 answers all of that with 1.1 lbs.
The one honest reservation is the fan while it fast-chargesA2, and the one honest limit is scale: a 2,100Wh camping weekend is 241% of what the Gen 2 delivers, so if that's your trip, neither of these is your unit. For everything smaller you're choosing between the same brand, the same warranty and one box that's better in every direction while costing less. Buy the C1000 Gen 2 and put the $69 toward panels.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Anker SOLIX C800 worth $69 more than the C1000 Gen 2?
No. The C800 is $599 to the C1000 Gen 2's $530, and that premium buys 768Wh instead of 1,024, a 1,200W inverter instead of 2,000W, 3,000 cycles instead of 4,000, and half the solar input. The only thing it hands back is 1.1 lbs. Nothing on the spec sheet makes up the difference.
Which Anker SOLIX can run a refrigerator?
The C1000 Gen 2, comfortably. A full-size fridge pulls 700-800W just to start, and 2,000W continuous with 3,000W surge absorbs that with room for other appliances alongside. The C800's 1,200W will start most fridges but leaves little headroom for anything running at the same time.
How fast does the SOLIX C1000 Gen 2 recharge?
About 49 minutes from a wall outlet, which reviewers clock as quicker than the original C1000's 58 to 80 minutes. The C800 is close behind on AC at 58 minutes with a 600W adapter. The real separation is solar: 600W of input against 300W, so on panels the Gen 2 refills a larger battery in far less of the day.
Is the Anker SOLIX C800 quieter than the C1000 Gen 2?
On the spec sheet, no: the C800 is rated 45 dB under load against the Gen 2's 35 dB. Under a heavy load the picture flips, because the Gen 2's fans climb to around 55 dB once you're past 1,000W or fast-charging, while the C800 is described as only a mild hum at its ceiling. At low draw both are effectively silent. If your unit refills overnight beside your bed, that's the single point in the C800's favor.
Can you add more battery to the Anker SOLIX C800?
No. The C800 is fixed at 768Wh, so size it for what you need on the day you buy it. The C1000 Gen 2 starts at 1,024Wh and accepts Anker expansion batteries, which means the one you can grow already holds more at its base than the sealed one holds when full.
