Head-to-head test
Anker SOLIX C800 Plus vs Anker SOLIX C800X
Anker SOLIX C800 Plus vs Anker SOLIX C800X: the same 768Wh pack, the same 1,200W inverter, the same 24 lb box, the same 5-year term. The C800X costs less and its listing includes a 100W solar panel, so buy it unless you need a published noise figure to point at before a power station goes next to your bed.

Spec deltas
Same 768Wh pack. Same 1,200W inverter with the same 1,600W peak. Same 24 lb carry, same 3,000-cycle minimum, same five-year term, same 300W solar ceiling, same 100W USB-C port. The C800 Plus asks $649 for that sheet, the C800X asks $450, and Anker sells the C800X bundled with a 100W solar panel, so the smaller number is also the one that arrives with something to charge it from.
The Plus is named for the telescoping light pole in its top compartment, and that pole is what the premium is supposed to be for. Owners trying to tell the lineup apart report that the X carries it too, and that the only model without it is the plain C800B1B2B11. They also say Anker's own materials never spell this out, which is why the question keeps coming back in review comment threadsB2.
So take the C800X, and here is the catch before you have to go looking for it. The X's field record is thin and lives almost entirely in one YouTube channel's comment threadsB0, every measured figure circulating for it traces back to one affiliate site claiming a test nobody can checkB15B16, it publishes no noise figure at all, and one owner spotted it marked Final Sale on Anker's Canadian storeB5. None of that is a fault in the hardware. It is a gap in the paperwork, and the paperwork is what the Plus's premium actually buys.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Typical price
And the gap is wider than those two prices suggest, because one of them includes a panel. The 300W solar ceiling both units share is an empty socket until you buy something to plug into it, and only one of these two prices arrives with a start on it. An owner who went shopping for the C800X found it offered with a 100W panel or a 200W panel and nothing elseB4, which is the real comparison here: a station plus a panel against a station.
Both units hold 768Wh at a 3,000-cycle minimum, which works out to the same 2,304 lifetime kWh through each pack.The C800 Plus is $649 and the C800X is $450.The C800X's price is a bundle price: Anker's listing pairs it with a 100W solar panel.
Why it mattersIf you came to choose between these two on capacity, stop. The pack is identical, so the only thing left to compare is what each price puts in the box.
If the X carries that same pole, the premium buys neither watt-hours nor storage. It buys a second copy of a feature that already costs you the cubby, and the reason a buyer cannot check this for himself is that Anker's materials never lay the lineup outB2. One reviewer called the pole a little over the top and another stopped packing separate lanterns after the first weekA2A14, so it is a feature people genuinely split on. Both of these units have it either way.
A reviewer of the C800 Plus complained there is nowhere to keep the cords when they are not in useA3.The light pole lives in the top compartment, and one buyer picked the pole-less C800 specifically to keep that space for his own lights, chargers and cablesB11.Owners comparing the lineup say both the X and the Plus carry the pole and only the base C800 does notB1B2.
Why it mattersDo not pay up for the lights. If the cubby is what you actually want, the model to look at is the base C800, and it is not on this page.
The honest reading has nothing to do with which fan is quieter. It is about which one you can hold to a number: the Plus's noise is documented from both ends, a published figure plus hands-on accounts of exactly when the fan stops being polite, while the only dB claim that exists for the X comes from one affiliate site's unverified testB0B16. On a nightstand you are choosing between a known quantity and an unknown one, not between two numbers.
A CPAP night is about 40W for eight hours, 320Wh against the 653Wh both units hold after the scenario model's flat 85% derate, leaving 333Wh spare on either.The Plus publishes 45dB, a spec-sheet best case rather than a measurement, and the C800X publishes nothing at all.Reviewers of the Plus found the fan unavoidable in a quiet house once the room passed 80F at a 1,030W average, and manageable at roughly arm's length during fast chargingA1A11.
Why it mattersThe bedroom or CPAP buyer who cannot hear the unit before buying is the one person here who should pay the Plus premium. Everybody else is paying for paperwork.
So the expensive mistake on this page is not picking the wrong one. It is buying either one when the load list needed twice the pack, and because neither expands, the box you carry home is the ceiling for as long as you own it. Owners do have a workaround, feeding an external LiFePO4 pack into the 11-60V XT-60 solar input, and the experienced reply is the one to listen to: you pay the MPPT conversion losses, push the energy through the internal cells on its way to your load, and give up your only charging input to do itB12B13.
Both units are 768Wh, which the scenario model derates to 653Wh usable.Weekend camping wants 2,100Wh and both come up 1,447Wh short; a van-life day wants 4,685Wh and both cover about 14%; the tailgate wants 670Wh and both miss it by 17Wh.Neither unit expands, and reviewers flag 768Wh as the awkward middle that will not carry kettles or some coffee machinesA5A10A12.
Why it mattersIf your list looks like the weekend-camping or van-life column, close both tabs and shop a larger station. The money you save on the X will not buy you the watt-hours you are missing.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: Identical packs at an identical 3,000-cycle minimum put the same 2,304 lifetime kWh through both units, so every cost-per-kWh difference here is the $649-against-$450 price gap and nothing else.
cost / lifetime kWh
Both packs retire with the same 2,304 kWh through them, so the cheaper unit is cheaper per kilowatt-hour by exactly the amount it is cheaper at checkout. Say that once and the rest of the arithmetic takes care of itself: twenty cents a lifetime kilowatt-hour against twenty-eight, with identical cells, an identical cycle rating and an identical five years of cover standing behind both figures.
What the table cannot show you is what each price includes. The C800X's number is a bundle number, the station with a 100W solar panel, and both units cap solar input at 300W. So the cheaper unit is also the one that shows up partway toward filling that ceiling. Anyone comparing these two as bare boxes is comparing the wrong two things.
What the Specs Don't Tell You
Selected because: Noise is the only spec these two sheets disagree on, and the disagreement is that one of them does not publish a number.
Anker prints a noise figure for the Plus and none for the X, and the temptation is to read the silence as a confession. It is not one. Two units with the same pack, the same 1,200W inverter and the same 24 lb chassis are asking their fans to do the same work; one of them tells you what that sounds like on a good day in a quiet mode, and the other tells you nothing.
The warranty is the same five years on both, which is worth saying out loud because the per-dollar version of that figure looks like a difference. It is not. Identical terms divided by different prices produce different numbers, and the only thing varying is the price you already knew about.
Your Life, Your Pick
Selected because: Both units hold 768Wh, so they pass and fail every scenario together, which makes this the section that tells you whether either is big enough for you.
Five of these six scenarios fail on both units, by the same watt-hours, in the same direction. The tailgate is the cruel one: 670Wh wanted, 17Wh missing, which is about a phone charge. Drop one string of lights and both finish the evening, and the 400W startup that actually gives people pause at a tailgate sits well inside the 1,600W peak both units publish.
The one scenario they both cover outright is the CPAP night, and that is the scenario where capacity was never the question. A 320Wh load against 653Wh of usable pack is a comfortable night on either box, and that comfort is exactly why the decision moves to the fan, where only one of the two has said anything on the record.
Growth Path
Selected because: Neither unit expands, so 768Wh is the ceiling for as long as you own it, whichever one you buy.
Neither unit expands, and that is not a mark against either of them. A 768Wh station at 24 lbs is a complete object, and both of these are the same complete object. What it does mean is that the sizing decision happens once, at checkout, and the scenario table is where you check your work.
The workaround exists and it is not free. Owners have run an external LiFePO4 pack into the 11-60V XT-60 solar input and called the unit expandedB12; the reply worth reading points out that you have paid the MPPT conversion losses, pushed the energy through the internal cells on its way to the load, and spent your only charging input to do itB13. That is a clever fix for a unit you already own, not a reason to buy a 768Wh box expecting to grow it.

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 C800 Plus comes up 1,447Wh short (about 31% covered), the SOLIX C800X 1,447Wh (31%). Treat this as partial cover — enough for the essentials in it, not the whole list.

Neither unit
Neither unit covers this scenario's 1,645Wh: the SOLIX C800 Plus comes up 992Wh short (about 40% covered), the SOLIX C800X 992Wh (40%). Treat this as partial cover — enough for the essentials in it, not the whole list.

SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
Both cover the night and it is not close: about 40W for eight hours is 320Wh against 653Wh of usable pack, leaving 333Wh spare on either unit. Which means capacity is not the spec you are buying here. The one that matters is the fan at 3 a.m., and on that the two part company only in what they will tell you, because the C800 Plus publishes a noise figure and the C800X publishes nothing. Same pack, same inverter, same night; one of them has gone on the record.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h

Neither unit
Neither unit covers this scenario's 910Wh: the SOLIX C800 Plus comes up 257Wh short (about 72% covered), the SOLIX C800X 257Wh (72%). Either gets you most of the way, so this is a scenario you plan around rather than one you should rule them out for.

Tailgate Party
Game day power for the crew
Neither unit
Seventeen watt-hours short. That is all that separates either of these units from finishing a 670Wh tailgate, and it is about a phone charge. Skip one string of lights or accept an earlier last song and both get there, and the 400W startup that genuinely gives people pause here sits well inside the 1,600W peak both units publish. Nothing to choose between them, which is the theme of this page.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
A van-life day wants 4,685Wh and these units hold 653Wh usable, about 14% of the job. That is not a close call between two power stations, it is the wrong shelf. Neither one expands, so there is no version of either that grows into this. Buy a larger station, or buy two batteries and a plan, and come back to these two for the weekend trips they are actually sized for.

Conclusion
September 13, 2026
Verdict: the SOLIX C800X
Buy the C800X. These two publish the same 768Wh pack, the same 1,200W inverter with a 1,600W peak, the same 24 lb carry, the same 3,000-cycle minimum, the same 300W solar ceiling and the same five years of cover, and the C800X asks $450 against the C800 Plus's $649 with a 100W solar panel included in its listing. So the premium buys no watt-hours, no output and no warranty. What it buys is documentation: the Plus is the only one of the two with a published noise figure, and its record comes from hands-on reviews rather than from a single affiliate site's unverified testA0B0B15. If this is going beside a bed and you cannot hear it before you pay, that is worth the premium. For a desk, a truck bed or a picnic table, take the cheaper identical box and put the difference toward more panel.

Runtime model
Runtime = (rated capacity × 0.85 inverter efficiency) ÷ device wattage. Solar recharge estimates assume panels deliver 70% of rated output. Cold weather, battery age, and stacked loads reduce real-world results.
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 Plus rates 3.8/5 (32nd percentile of 20 Compact-class units), and SOLIX C800X rates 4.3/5 (58th percentile of 20 Compact-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
SOLIX C800 Plus: 45dB Is a Floor, Not a Verdict
45dB is Anker's best-case figure, the number a spec sheet prints for a light load in a quiet mode, not what you hear when the fan has work to do. Expect louder during fast AC charging and on a hot day at sustained wattage. It is still the only published noise number anywhere on this page, and that counts for something: the SOLIX C800X prints no figure at all, so there is no floor to compare against, never mind a ceiling.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. Worth saying because the per-dollar framing can suggest otherwise: the SOLIX C800X works out at 11.1 years of cover per $1,000 spent against the SOLIX C800 Plus's 7.7, but that spread is the price gap, not the terms.
SOLIX C800X: No Published Noise Figure
Anker publishes no dB number for the C800X, which is not the same as the C800X being louder. It means there is nothing to hold it to. The two units publish the same pack, the same 1,200W inverter and the same 24 lb weight, so their fans have the same work to do; one of them documents the result and the other does not. If this is going in a bedroom or next to a CPAP, that gap is the single best reason on this page to pay more.

Analyst note
The SOLIX C800X wins on both sticker price and long-term value. At $0.20/kWh over its lifetime, it's meaningfully cheaper to own. Clear value winner. One thing to know reading the table: both carry the same 3,000-cycle rating, so the lifetime rows are sticker price and capacity in disguise — the wear horizon is identical and decides nothing here.

Analyst note
Neither expands, and that's no knock on either — each is a complete unit at a fixed size. They hold the same 768Wh, so capacity can't break the tie: decide on price, weight, and the rest, and know that whichever you pick is the ceiling.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
Anker SOLIX C800 Plus
The Plus's record is professional rather than personal. Our sweep turned up no owner forum threads specific to the Plus as distinct from the plain C800 or the X, so what exists comes from hands-on review sites, and one of those reads like templated SEO content and should be weighted accordinglyA0A14. Nobody in that set has owned the unit six months and reported back, and nobody has run a CPAP on itA0.
Within that limit the picture is consistent. The fan is noticeable when the unit is working: unavoidable in a quiet house above 80F at a 1,030W average, and manageable at roughly arm's length during fast chargingA1A11. Light loads are undramatic, with a fridge and freezer taking 10% of the pack in eight hoursA6, and one reviewer pulled the wall plug mid-session and watched his monitor carry on without a flickerA4.
The complaints cluster on capacity rather than execution, with reviewers calling 768Wh an awkward middle that will not carry kettles or some coffee machinesA5A10A12. The app gets unusual praise for monitoring and firmware delivery, with nobody reporting the connectivity trouble these apps normally collectA7A15. The light pole splits people: one reviewer called it a little over the top, another stopped packing lanterns after the first week, and a third noted that what it displaced was where the cords used to liveA2A14A3.
“The pole light felt is a little over the top and unnecessary.”

Anker SOLIX C800X
The X's field data is thin and concentrated in one place, the comment threads under a single YouTube channel's two C800X videos, with Reddit and the DIY solar forums returning nothing about this modelB0. Treat that as unresolved rather than clean. The most repeated theme is not performance at all, it is confusion: buyers cannot say what separates the X from the C800 and the Plus, and they say Anker never spells it outB1B2.
The owners who kept theirs are quietly satisfied. One runs PCs and a router off it and reports no interruption when wall power dropsB6; another has had it about a year, runs a heater on low, a fan and a toaster, and has nothing to complain aboutB14. Support is a coin flip on this evidence, with one owner describing order mistakes Anker would not correct and telling people not to roll the dice, and another sending in a dead USB-C port and getting the unit back repaired in three daysB8B10.
Two hardware faults are on record and both come from 2024 stock: a false low-temperature reading that shut the inverter down at living-room temperature on current firmware, and a reverse-polarity AC outlet on early units that killed a window air conditionerB7B9. They may not describe what ships now. The part to hold onto is that every measured number circulating for this unit, the fan staying below 30dB at a 290W load, the 24 to 30 hour fridge runtime, the 8% capacity loss at 28F, traces to one affiliate site claiming a test nobody has verified, while the highest-traffic video review contains no measurements at all and its viewers said soB15B16B17B18. One owner also saw the X marked Final Sale on Anker's Canadian siteB5.
“I am confused the Anker C800x isn't supposed to have the lights in the top compartment? Those are supposed to be in the Anker solix C800 plus.”

“I am confused the Anker C800x isn't supposed to have the lights in the top compartment? Those are supposed to be in the Anker solix C800 plus.”

“I have same question re: the 800, 800X and 800 Plus. So far, only thing I know fir sure is that the X & + versions have flashlights & telescoping rod in top compartment, while the 800 does not... Anker doesn't spell it out anywhere I can find.”

“The C800X is showing as "Final Sale" on the Canadian site, so it sounds like it may be phased out soon.”

“A pretty good product, but pray you never need customer support. They made several mistakes with my order... It was their complete lack of willingness to try and correct them. Unless you can roll the dice for $500, I would avoid it.”

“I already have flashlights and lanterns that take 18650 and 21700 lithium batteries, so I opted for the C800 without the lights for $429. I would rather have the extra storage space on top for my own lights, chargers and cables.”

“Can't expand? Get a 5k to 15k rack mount battery. A cable to attach it to the solar input, done. Expanded... The rack mount battery is 52.1 volts and the solar input on the Anker can handle 60.”

“Yes its expandable××there losses going into the solar charge controller and then extra wear on the batteries as you're charging the internal batteries first then discharging them. Plus you're limited to the capacity of the mppt and you can no longer use it to charge the unit.”

Who Should Buy Which
Buy the SOLIX C800 Plus if you…
- →You are standing in a bedroom deciding what goes on the nightstand, and you cannot audition a fan you have not bought yet. The Plus is the only one of the two with a published noise figure and with hands-on accounts of when that fan stops being politeA1A11. That is what the premium is for.
- →You want the model that is unambiguously current, rather than the one an owner saw marked Final Sale on another country's Anker storeB5. Both carry the same five years, but stock and spares tend to follow the model still being pushed.
Buy the SOLIX C800X if you…
- →A desk UPS for a router and a couple of PCs. Both units publish a switchover no worse than 20ms, and an owner running exactly that load reports no interruption when the power dropsB6. Pay less for the same promise.
- →Camping and tailgating where you want the lights and a panel. Same 768Wh, same 24 lbs, the same top-compartment pole owners report on both boxesB1B2, and a 100W panel inside the price.
- →Anyone who has read both spec sheets, found them identical, and assumes they must be missing something. You are not.
If neither fits
If your load list looks like the weekend-camping or van-life column, both of these are the wrong size and no amount of choosing between them fixes it: 768Wh derates to 653Wh usable, a weekend wants 2,100Wh, a van-life day wants 4,685Wh, and neither unit expands. Shop a larger station with a real expansion port, or plan on two batteries from the start. Same answer if you want to boil a kettle or run a drip coffee maker, which reviewers put outside what 768Wh will carryA10.
The Bottom Line
Take the C800X. Two units, one spec sheet, and the cheaper of the two prices is the one with a solar panel attached to it. The feature the Plus's name is selling, that light pole in the top compartment, is a feature owners report on both boxesB1B2, so the premium buys no watt-hours, no output, no runtime and no coverage.
What it buys is a published noise figure and a thicker file of hands-on reports, which is not nothing if this is going beside a bed and you cannot hear it first. That is the whole decision. If it is going under a desk, in a truck or on a picnic table, buy the cheaper identical box and spend the difference on more panel.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
What is actually different between the Anker SOLIX C800 Plus and the C800X?
On the spec sheets, the price. Both are 768Wh, 1,200W with a 1,600W peak, 24 lbs, a 3,000-cycle minimum, 300W of solar input, 100W USB-C and five years of warranty. The Plus publishes a 45dB noise figure and the X publishes none, and the C800X's price is a bundle that includes a 100W solar panel. Owners who have handled them say both carry the top-compartment light pole, and that the base C800 is the one without it.
Is the C800X quieter or louder than the C800 Plus?
Nobody can tell you, and anyone who does is guessing. Anker publishes 45dB for the Plus, which is a spec-sheet best case rather than a measurement, and publishes nothing for the X. The only dB claim in circulation for the X comes from a single affiliate site describing a test that cannot be verified. If quiet is your deciding factor, buy the one with a published figure, or buy wherever the return window is longest.
Does the C800X price include a solar panel?
Yes. Anker sells the C800X bundled, and an owner who went looking describes finding it offered with a 100W panel or a 200W panel and calls the listings hard to locate. That changes the comparison: the C800X's $450 is a station plus a panel, while the Plus's $649 is a station price. Both cap solar input at 300W, so the bundled panel is a start on that ceiling rather than the end of it.
Can you add a second battery to the C800 Plus or the C800X?
No. Neither has an expansion port, so 768Wh is the ceiling on both. Owners get around it by feeding an external LiFePO4 pack into the 11-60V XT-60 solar input, and the experienced counter is worth hearing: you lose energy in the MPPT conversion, run it through the internal cells before it reaches your load, and give up your only charging input while it is connected. Size it up front instead.
Is the Anker SOLIX C800X being discontinued?
We cannot confirm it. One owner reported seeing it marked Final Sale on Anker's Canadian site, and the model has been reviewed under this name since 2024 even though the US listing is new. Final Sale is a stock signal, not a warranty statement, and both units carry the same five-year term. If you want accessories and spares to stay easy to find for years, that is a fair argument for paying the Plus premium.
