Anker SOLIX C800X
The C800X is the C800 Anker kept, and buyers cannot tell it from the C800 or the C800 Plus; the light pole is the only difference anyone names. 768 watt-hours at 24 pounds, a CPAP night on half the tank, one head-to-head, lost. Owners quoted by reviewers run a router, a heater and a toaster without complaint.

What the SOLIX C800X actually runs
The load profiles every comparison on the site is scored on, computed for this unit alone: energy needed against the usable tank after inverter losses, and whether the inverter holds and starts the biggest single load.

03 · From the verdicts
Who it is for, and when a rival won instead
Each line is lifted from a written matchup where it decided the verdict, and links to the page it came from. Repeated across many matchups means it is the unit’s signature, not one author’s opinion.
Buy the SOLIX C800X if…
You own no solar gear and want one box that arrives complete. The C800X's price includes a 100W panel, and for a campsite or a picnic table that is a real head start.
Decided 2 matchups · read one →
You want a cheap UPS for a router and a desktop, and can live with a transfer rated at 20ms rather than 10ms.
Decided 2 matchups · read one →
Your list honestly tops out under 1,200W and under 768Wh: a CPAP, a laptop, phones, lights, a fan. It finishes a CPAP night with 333Wh untouched, and it gives up nothing on weight.
You'll carry it more often than you'll load it. 24 lb against 28.4 lb, and 768Wh still covers a CPAP night with 333Wh spare.
A rival won when…
You're running a CPAP and you'd rather buy the unit whose behaviour at low load is actually on the record [A1][A2].
Decided 2 matchups · read one →
You want the cheapest honest route to 768Wh because you already own panels, or because you have no intention of charging from the sun at all.
Decided 2 matchups · read one →
The cold-snap household. If a 1,500W space heater is the reason you are buying, this is the only one of the two that runs it, with 500W of continuous headroom left over.
Anyone putting the unit in a bedroom or beside a CPAP. It is the only one here with a published noise figure, and at a 40W draw you sit in the quiet end of its range rather than the fast-charge end.

How to read this
- Usual is the price the unit carried most of the time, tested for how long it held rather than how often we looked. A weekend promotion cannot move it.
- Best is the lowest price we have read on the store itself. Typed coupon codes, member-only prices and marketplace listings are not counted; anything applied automatically at checkout is.
- A gap in the line is a day we could not read a price. We never draw across one, and we never show the store’s own “was” price.

Will the Anker SOLIX C800X go on sale for Black Friday?
Price to beat $450Nobody knows until Anker SOLIX moves, but in 55 days we have tracked it, it has never been discounted, so any real cut would be a first. We read the store twice a day, and the moment it drops it shows on our Black Friday deals page.

Reviewer consensus
6/18 positive excerpts, 1 sources
Buyers cannot tell the C800X apart from the C800 and C800 Plus; the top-compartment light pole is the only difference anyone can name, and owners say Anker's own materials never spell the lineup out.

Questions people ask
Is the Anker SOLIX C800X being discontinued?
We cannot confirm it. One owner reported seeing it marked Final Sale on Anker's Canadian site [B5], and the model has been reviewed under this name since 2024 even though the US listing is new [B0]. 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.
Does the Anker SOLIX C800X come with a solar panel?
Yes. Anker sells the C800X bundled with a 100W panel rather than as a bare unit, which is the main reason the two price tags on this page look identical. Owners have reported the various bundles being hard to find on Anker's own site, so check exactly which panel is in the box you're adding to your cart [B4]. If you already own panels, you're paying for one you don't need.
Can the Anker SOLIX C800X be expanded?
No. It's sealed at 768Wh, which is below the 1,056Wh the C1000 starts at, so the only way past that number is a second station. Some owners route an external LiFePO4 pack into the XT-60 solar input and treat it as expansion [B12], but that costs conversion losses through the charge controller, extra cycling on the internal pack, and the use of the only charging input you have [B13]. The C1000 takes proper Anker expansion batteries instead.
Can the Anker SOLIX C800X run a 1,500W space heater?
No. Its inverter is rated 1,200W continuous with a 1,600W peak, so a 1,500W heater sits above its continuous rating, and a peak rating does not carry a load like that for an evening. The C1000 Gen 2 runs the same heater with 500W to spare, and reviewers confirm it in practice [A3]. If a heater is the plan, that single spec ends the comparison.
Can the Anker SOLIX C800X start a refrigerator?
Plan around roughly 800W of motor start, not its 1,200W rating. Compressors pull about twice their running draw at startup, so halving the C800X's 1,600W peak gives you the honest ceiling. A fridge that runs under about 400W should wake up fine. Anything larger belongs on the C1000X Gen 2, whose 3,000W peak works out to roughly 1,500W of cold start, which is more than the C800X can run continuously.
