Anker SOLIX C1000 Gen 2 vs Anker SOLIX C800 Plus
Anker's own price list just erased the only reason anyone chose the C800 Plus: pay $99 more, get a third less capacity, less output, and no room to grow.

Spec deltas
The Anker SOLIX C1000 Gen 2 costs $550. The Anker SOLIX C800 Plus costs $649. Not long ago that math ran the other way, and the entire case for the C1000 Gen 2 was whether its extra capability was worth paying more for. That case is dead: the bigger, faster, more expandable unit is now also the cheaper one, by $99.
Nothing about the spec sheet flipped to make this close. The C1000 Gen 2 holds 1,024Wh against the C800 Plus's 768Wh, a third more capacity. It pushes 2,000W continuous against 1,200W, and 3,000W surge against 1,600W — almost double the headroom for starting anything with a compressor or a motor. It switches over in 10ms during an outage against the C800 Plus's 20ms, and it's the only one of the two that accepts an expansion battery later.
The one place this isn't a clean sweep is fan noise, and it's worth naming before the verdict: the C1000 Gen 2's 35dB rating and the C800 Plus's 45dB figure aren't measured at the same operating point, so the gap on paper won't necessarily match what you hear once both units are actually working. Everywhere else — capacity, output, surge, recharge speed, expansion, and cost per lifetime kilowatt-hour — the C1000 Gen 2 wins outright, and now it wins on price too.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
That $99 isn't buying the C800 Plus anything: it holds a third less capacity, 768Wh against 1,024Wh. You're now paying more for less tank, not less for less tank.
SOLIX C1000 Gen 2: $550SOLIX C800 Plus: $649SOLIX C1000 Gen 2: 1,024Wh capacity, SOLIX C800 Plus: 768Wh capacity
Why it mattersAnyone assuming the C800 Plus is still the 'budget' pick in this pair is working from stale pricing — it no longer saves you anything, and it costs you capacity.
continuous output
That's why the C1000 Gen 2 clears Tailgate Party outright and the C800 Plus can't: it needs 103% of its own usable capacity to finish the same afternoon. The surge and capacity gap isn't theoretical here — it's the difference between finishing the job and running out.
SOLIX C1000 Gen 2: 2,000W continuous, 3,000W surgeSOLIX C800 Plus: 1,200W continuous, 1,600W surgeTailgate Party needs 670Wh: C1000 Gen 2 uses 77% of usable capacity, C800 Plus needs 103%
Why it mattersIf you're running anything with a compressor or motor start, the C800 Plus's lower ceiling is a hard wall the C1000 Gen 2 doesn't have.
cost / lifetime kWh
The sticker price per watt-hour and the lifetime cost per kilowatt-hour used to point in opposite directions for this pair — one favored the cheaper unit, one favored the bigger one. Now both point the same way, at the same unit: $.54 per Wh and $0.13 per lifetime kWh, both lower on the C1000 Gen 2.
SOLIX C1000 Gen 2: $0.13 cost per lifetime kWh, 4,000 rated cycles, $.54 per WhSOLIX C800 Plus: $0.28 cost per lifetime kWh, 3,000 rated cycles, $.85 per Wh
Why it mattersThere's no version of this purchase — cheapest today, cheapest over five years, most energy per dollar — where the math favors the C800 Plus anymore.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The price flip is the whole story now; this is where the $99 reversal and the cost-per-lifetime-kWh gap both live.
cost / lifetime kWh
Start with the sticker: $550 for the SOLIX C1000 Gen 2, $649 for the SOLIX C800 Plus. That alone would be reason enough, but the ownership math doesn't even bother making it close. The C1000 Gen 2 costs $0.13 per lifetime kilowatt-hour; the C800 Plus costs $0.28 — more than double, because 4,000 rated cycles against 1,024Wh push 4,096 lifetime kWh through the same five-year warranty, against 2,304 kWh for the smaller, shorter-cycle-life C800 Plus.
Even priced per warranty year the story doesn't change: $110 a year for the C1000 Gen 2 against $130 for the C800 Plus, on the same five-year term. Every way you slice this number, it comes out the same unit ahead.
What the Specs Don't Tell You
Selected because: Expansion, warranty value, cycle life, and switchover speed all land the same direction; noise is the one honest complication worth flagging.
rated cycles
Expansion, warranty value, and cycle life all resolve the same way. The C1000 Gen 2 accepts Anker's expansion batteries; the C800 Plus is sealed at 768Wh for good. Its 4,000 rated cycles against the C800 Plus's 3,000 is the reason the lifetime-cost math above isn't close. And its 10ms UPS switchover beats the C800 Plus's 20ms, though both are fast enough that most connected electronics won't notice either handoff.
Noise is the one place this isn't a clean sweep. The C1000 Gen 2 is rated at 35dB against the C800 Plus's 45dB, but those two numbers aren't necessarily measured at the same operating point — one may reflect a quieter load than the other. Don't assume the 10dB gap on the spec sheet survives once both units are actually working; it's the honest asterisk on an otherwise one-sided page.
Your Life, Your Pick
Selected because: Tailgate Party and CPAP Overnight show the capacity gap isn't abstract — it's the difference between finishing the job and running out.
Tailgate Party needs 670Wh. The C1000 Gen 2 covers it using 77% of its usable capacity; the C800 Plus needs 103% of its own — over the tank entirely. CPAP Overnight is a job both clear, but the C1000 Gen 2 does it on 37% of usable capacity against the C800 Plus's 49%, real margin if a second rough night follows the first.
Weekend Camping, the 8-Hour Blackout, Remote Workday, and Van Life Daily outsize both units regardless of which you buy — Van Life Daily alone needs more than five times the C1000 Gen 2's usable capacity and more than seven times the C800 Plus's. If your real load looks like any of those four, neither of these is sized for it; look higher.
Growth Path
Selected because: Expansion is the one advantage that compounds if needs grow, and it now comes bundled with the lower price instead of costing extra.
solar input
The C800 Plus is a closed box: 768Wh is what you'll ever have. The C1000 Gen 2 starts at 1,024Wh and accepts Anker's expansion batteries if that ever stops being enough — a real path the C800 Plus doesn't have at any price.
That used to be the tiebreaker you paid extra for. Now it comes bundled with the cheaper unit, which is what makes this comparison as one-sided as it is.

Conclusion
July 26, 2026
Verdict: the SOLIX C1000 Gen 2
Every axis that used to require a trade-off now points the same direction. The SOLIX C1000 Gen 2 is $99 cheaper than the SOLIX C800 Plus, holds a third more capacity (1,024Wh against 768Wh), pushes 800W more continuous output and almost double the surge headroom, switches over twice as fast during an outage, and is the only one of the two that can add capacity later. It's also cheaper to run: $0.13 per lifetime kilowatt-hour against $0.28. The one open question is fan noise under real load, where the spec sheet doesn't measure both units at the same operating point — but that alone isn't enough to change which one to buy.

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 24 Everyday-class units), and SOLIX C800 Plus rates 4.0/5 (39th percentile of 19 Compact-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
35dB and 45dB Aren't the Same Kind of Number
The C1000 Gen 2's 35dB rating and the C800 Plus's 45dB figure reflect different operating points, not a clean quieter-vs-louder split. Don't assume the 10dB gap on paper holds once both units are actually recharging or running a real load — it's the one spec on this page that isn't a clean win for either side.
One Closed Box, One With Room to Grow
The C800 Plus is sealed at 768Wh for the life of the unit — size it for your needs today, because there's no adding to it later. The C1000 Gen 2 starts at 1,024Wh and accepts Anker's expansion batteries if that number stops being enough.
Both Fast Enough, One Faster
The C1000 Gen 2 switches over in 10ms during an outage against the C800 Plus's 20ms. Both are quick enough that most connected electronics won't notice either handoff, so this rarely decides the purchase alone — but the margin costs nothing extra this time.
Same Warranty Length, Different Price Per Year
Both units carry a 5-year warranty, but the C1000 Gen 2's lower price spreads out to $110 a year against the C800 Plus's $130 — cheaper coverage on top of everything else.
More Cycles, Lower Price, Same Direction
The C1000 Gen 2 is rated for 4,000 cycles against the C800 Plus's 3,000, and it costs less to buy. That combination pushes its lifetime cost to $0.13 per kilowatt-hour against $0.28 for the C800 Plus — the cycle-life gap and the price gap now reinforce each other instead of pulling in opposite directions.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
Anker SOLIX C1000 Gen 2
Reviewers point to two real gains over the original C1000: HyperFlash charging that cuts a full recharge to roughly 49 minutesA1, and continuous output high enough to run a standard 1,500W space heater with headroom to spareA3 — coverage broadly calls it the mid-size unit to beat heading into 2026A4.
The recurring complaint is fan noise: nearly silent at light draw, but audibly ramping up during fast charging or heavy output, reaching around 55dB past 1,000WA2. It's the one place the newer unit doesn't uniformly beat the older one, and it tracks with the honest catch above.
“Fast HyperFlash charging — a full recharge in roughly 49 minutes, noticeably quicker than the original C1000's ~58-80 minutes.”

Anker SOLIX C800 Plus
Reviewers consistently flag that the C800 Plus can't handle genuinely heavy-duty appliances like kettles or some coffee machinesB10; one called its 768Wh capacity 'an awkward middle ground,' noting it's significantly less than what a same-priced rival offersB12. On the plus side, one reviewer confirmed it handles an actual outage cleanly: unplugging the power supply produced no monitor flicker, just continued operationB4.
Fan noise under sustained heavy draw was 'unavoidable and quite present,' by one accountB1, though another called it manageable at arm's length during fast chargingB11 — reviewer sentiment on the unit overall remains strongly positive despite these caveatsB13.

Who Should Buy Which
Buy the SOLIX C1000 Gen 2 if you…
- →You want the better-specced unit and it's now also the cheaper one — more capacity, more output, more surge headroom, and a real expansion path, for $99 less than the C800 Plus.
- →You need genuine surge headroom for a compressor or motor start, or you want the option to add capacity later without buying a second whole unit.
Buy the SOLIX C800 Plus if you…
- →You'll run it hard and continuously in the upper half of its power range, and you'd rather have a fan that's steady at a rated 45dB than one whose quiet 35dB rating doesn't hold at low load, per reports of the C1000 Gen 2 climbing toward 55dB under heavy sustained drawA2.
- →You found the C800 Plus meaningfully discounted below its current $649 list — at full price, there's no longer a capacity, output, ownership-cost, or expansion argument in its favor.
If neither fits
If your real need is a multi-day camping trip, an 8-hour multi-appliance blackout, a full remote workday, or daily van-life power, both fail outright — the scenario math puts both past 100% of usable capacity, and Van Life Daily puts the C1000 Gen 2 past 500% and the C800 Plus past 700%. Look at a 1,500Wh-plus unit or a true expansion setup instead of choosing between these two.
The Bottom Line
This comparison used to hinge on whether the C1000 Gen 2's extra capability was worth paying more for. That question is gone. At $550 against the C800 Plus's $649, it's now the cheaper unit — and it still holds a third more capacity, almost double the surge headroom, a faster outage switchover, real expansion room, and less than half the cost per lifetime kilowatt-hour.
The only asterisk is fan noise under real load, which doesn't clearly favor either unit despite what the spec sheet implies. That's not enough to change anything: buy the C1000 Gen 2, and keep the $99.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Anker SOLIX C1000 Gen 2 cheaper than the C800 Plus?
Yes — $550 against $649, a $99 gap that runs the opposite direction from what it used to. The C1000 Gen 2 is now both the cheaper unit and the one with more capacity, more output, and more surge headroom.
Which Anker power station should I buy, the C1000 Gen 2 or the C800 Plus?
The C1000 Gen 2, for almost every buyer. It costs $99 less, holds a third more capacity (1,024Wh against 768Wh), pushes almost double the surge headroom, and is the only one of the two that can add capacity later. The C800 Plus only makes sense if you find it discounted well below its current $649.
Is the C1000 Gen 2 actually quieter than the C800 Plus?
Not necessarily under real load. Its 35dB rating and the C800 Plus's 45dB figure aren't measured at the same operating point, and owners report the C1000 Gen 2's fans climbing toward 55dB during fast charging or heavy output. Judge this on load-tested noise, not the spec-sheet gap.
Can the SOLIX C800 Plus be expanded later if I need more capacity?
No — it's a closed system for the life of the unit. The C1000 Gen 2 accepts Anker's expansion batteries, so it can grow past its starting 1,024Wh if your needs increase.
Which one is cheaper to own over time?
The C1000 Gen 2, and now it's cheaper up front too. It costs $0.13 per lifetime kilowatt-hour against the C800 Plus's $0.28 — more than double — thanks to 4,000 rated cycles against 3,000.
