C1000
- you already own one: nothing to upgrade
- its US page now opens the C1000X listing, where it is sold under the C1000 label
- a retailer still lists it: compare prices, not specs
C1000X
- you buy from Anker US today
- you want 1,800W and six outlets
- you’ll add one extra battery later
Prices and stock checked by our price engine on November 5, 2026 at 3:31 AM EST. Each product is rechecked several times a day; the time refreshes when you load the page.
Don’t pay extra for the letter X, and don’t wait for the C1000 to come back.
Anker US no longer has a separate listing for the Anker SOLIX C1000: its US page redirects to the Anker SOLIX C1000X, and the C1000X’s tech specs and purchase option are labelled C1000. Every published figure matches: 1,056Wh of LFP rated for 3,000 cycles, 1,800W from six outlets with 2,400W SurgePad, 600W of solar, a 58-minute wall refill, one extra battery for 2,112Wh, 28.44 lb and 5 years of warranty once registered with Anker. If you own a C1000, nothing newer replaces it like for like except its own twin; if you’re buying, the two labels are the same station, so compare today’s prices in the price section.
Below: what we could and couldn’t find that separates them, a 20-second calculator for your own gear, seven modeled situations, a third option, and what published tests found on each label.
No spec difference we could verify. Anker US now sells the C1000 under the C1000X listing, with the same 1,056Wh, 1,800W, six outlets, 600W of solar and expansion to 2,112Wh. Pick on price and seller, not on the name.
- you own one: same hardware
- you’ll add a BP1000
- you run up to 1,800W
- you buy new from Anker US
- you want six outlets
- you’ll use 600W of solar
What differs, and what doesn’t
We compared the C1000 figures Anker published for the US with the C1000X’s US tech specs, line by line. These are the five things that could separate them; none is a hardware spec.

Estimates use 85% usable capacity and 70% of rated solar output. Real results vary with temperature, inverter load, shade and appliance cycling. Fridge and freezer watts are daily averages and do not include compressor startup surges.
Runtime by appliance, one at a time
Simple energy estimates, not measured runtimes. About 898Wh usable on both; OutdoorGearLab measured 897Wh out of a C1000, and CyberShack got close to 900Wh of AC out of an Australian C1000X.
Same battery, same runtime.
The C1000 and the C1000X both hold about 898Wh usable, so every appliance runs just as long on either one.Get our Black Friday alerts for Anker SOLIX

What it costs today
Same 1,056Wh battery: they cost the same today.
Prices refresh daily from Anker US.If a retailer still sells a C1000 under the old name, compare its price with the C1000X: the published specs match, so price and seller are the only things to weigh. Check that the seller is authorized, since Anker says registration activates the 5-year warranty.
The third option: the Anker C1000 Gen 2 at $549.99
Anker SOLIX C1000 Gen 2: $549.99 today
The real upgrade, unlike the X: 1,024Wh, 2,000W from five outlets, a 10ms UPS, a 49-minute wall refill and 4,000 cycles, at 24.9 lb. It drops the battery port. Pick it if you want a documented switchover and don’t need 2,112Wh. Our C1000X vs C1000 Gen 2 comparison goes deeper. See the C1000 Gen 2 at Anker.
Seven modeled situations, worked out
Same formula as the calculator above. The published specs are identical, so every result is the same for both; the verdicts say what that means for your purchase.
24-hour outage, essentials only
An evening and a night on either. AppleInsider ran a fridge and a router on a C1000X for 8 hours while charging an iPhone, an iPad and a Switch. For a full day, add one expansion battery.
A 1,100W microwave
Both run it within their 1,800W rating, with room for a fridge at the same time.
Home office through an outage
A workday on either. Anker US states no switchover time, but Trusted Reviews kept a PC and NAS running on a C1000 and AppleInsider tested a workstation on a C1000X.
Refill from solar, each at its maximum
Same 600W input, 11 to 60V, on both.
Refill from the wall before a storm
Anker’s figure for both. OutdoorGearLab measured 65 minutes in a C1000’s ultra-fast mode; CyberShack 54 minutes on an Australian C1000X.
Growing the system
One extra battery each. Anker’s C1000X listing sells it with the BP1000X; we found no official note on mixing the two names, so ask Anker before pairing a C1000 with a BP1000X.
Moving it
Same weight per Anker; AppleInsider’s spec list says 25 lb, which doesn’t match Anker’s 28.44 lb.
Nine more differences, the spec sheet and the box
Smaller gaps that rarely decide the purchase, then the full specifications and what ships in the box.
C1000 and C1000X weight, dimensions and full specifications
Weight: 28.4 lb for both the Anker SOLIX C1000 and the C1000X. Dimensions: 14.8 × 8.07 × 10.5 in for both. Everything else is in the sheet below.

07 · ChargingHow fast each one refills
Same published rates on both; the measured figures come from different reviewers and markets.
C1000: AC has priority over solar; no simultaneous charging (Anker FAQ)C1000X: same rule in its US FAQ
Our solar times assume panels deliver 70% of their rating; the brands’ figures assume ideal sun.
Every port, side by side

C1000X
Practical consequence: none. Same six outlets, same USB, same car socket, same battery port.
09 · NoiseNoise: C1000 vs C1000X
Both get loud at full power. OutdoorGearLab found the Anker SOLIX C1000‘s fan one of the loudest it tested at maximum load, and AppleInsider compared the Anker SOLIX C1000X‘s fans to a small aircraft landing.
Anker publishes no noise rating for either label, and we found no verifiable dB measurement.Every figure we found, with its source
No decibel figure published.
What reviewers heard: Its fan at maximum load was one of the loudest of all the power stations tested (OutdoorGearLab); the small fans sound slightly harsh near maximum AC load (Trusted Reviews, UK unit).
No decibel figure published.
What reviewers heard: When the fans kick in at high output or full-speed charging, the reviewer compares the sound to a small aircraft landing (AppleInsider).
Measured by a tester Brand figure
- Cap the AC charging speed in the Anker app overnight.
Cold, heat and storage: C1000 vs C1000X
The Anker SOLIX C1000 and the Anker SOLIX C1000X share the same limits: charging from 32°F to 104°F, running from −4°F to 104°F. Neither has a water rating.
Figures from Anker’s US tech specs for both labels.- Charge either one indoors in winter: neither charges below 32°F.
- For storage, turn off the outputs, keep it dry and cool, recharge to 100% if it drops below 30%, and fully charge it every 3 months (Anker’s C1000 documentation).
App, UPS and smart features
No difference: the Anker SOLIX C1000 and the Anker SOLIX C1000X use the same Anker app, take the same single extra battery and get the same UPS listing.
Anker US gives no switchover time for either, though reviewers kept PCs running on both.Can you add a battery later? Both take one extra battery for 2,112Wh. We found no official note on mixing a C1000 with a BP1000X, or a C1000X with a BP1000.
Does it work as a UPS? Anker US lists a UPS on both but gives no switchover time. Trusted Reviews kept a PC and NAS running on a C1000; AppleInsider tested a workstation on a C1000X.
Can it charge off-peak? Both let you schedule power use and set the AC charging speed in the Anker app.
How does the app connect? Both use the Anker app over Wi-Fi or Bluetooth, with real-time status from another room or away from home.
Warranty and support
Same coverage: Anker US lists 5 years for both the Anker SOLIX C1000 and the Anker SOLIX C1000X. Anker’s registration page says registering activates it.
Buy from a seller that honors Anker’s warranty, then register.Subject to each brand’s warranty terms and eligibility.
Anker rates both at 3,000 cycles to 80% capacity, about 8 years at one full cycle a day. Calendar aging and heat also reduce capacity, so read the rating as a ceiling.
- Check that the seller is authorized and register the unit with Anker when it arrives: Anker says registration activates the 5-year warranty.
What reviewers report
We have not lab-tested these two units. Here is what 6 published reviews found, with the source, author and date for each point. Reviews of UK and EU units are flagged: those models charge from 230V outlets and have different sockets, so their charge times and outlet findings don’t carry over to US units.

Practical limits before you buy
- Don’t pay a premium for either name. The published specs match line by line.
- Anker US no longer lists the C1000 on its own. Its page redirects to the C1000X.
- Check expansion battery pairing with Anker if you mix a C1000 with a BP1000X or a C1000X with a BP1000; we found no official compatibility note.
- Anker states no UPS switchover time for either.
- Both stop at 1,800W. A microwave and a coffee maker together overload them.
- Reviews of non-US units differ. CyberShack’s Australian C1000X charges faster than the Australian C1000; Anker US listed 1,300W for both.
- C1000, per its US documentation: AC and DC inputs cannot charge at the same time; AC input takes priority, then it switches to DC when AC charging ends.
- C1000, per its US documentation: SurgePad (up to 2,400W) works best with heat-generating devices and does not support precision instruments or voltage-sensitive devices.
- C1000, per its US documentation: Storage: turn off outputs, store dry and cool, recharge to 100% if below 30%, fully charge every 3 months.
- C1000, per its US documentation: Charging temperature 32 to 104F; discharging -4 to 104F. Max AC input 1,300W, solar 600W (11-60V).
- C1000X, per its US documentation: AC and DC inputs cannot charge it at the same time; AC has priority, then it switches to DC.
- C1000X, per its US documentation: Solar input 11 to 60V via XT-60, 10A max from 11 to 32V, 600W max.
Frequently asked questions
What is the difference between the Anker C1000 and the C1000X?
On Anker’s US spec sheets, none: 1,056Wh, 1,800W, six outlets, 600W of solar, 1,300W AC charging, one extra battery, 28.44 lb and 5 years of warranty on both once registered with Anker. Anker US now sells it under the C1000X listing.
Is the C1000 discontinued?
Anker US no longer lists it on its own: its C1000 page redirects to the C1000X, whose spec header still reads C1000.
Is the C1000X the same as the C1000 Gen 2?
No. The C1000 Gen 2 is a different unit: 1,024Wh, 2,000W, a 10ms UPS and 4,000 cycles, with no battery port.
Which is cheaper?
Anker US only prices the C1000X now; see the live figure in the price section. If a retailer still sells a C1000, the published specs match, so compare its price with the C1000X.
Can I use a BP1000 with a C1000X?
Both take one expansion battery for 2,112Wh. We found no official note on mixing the BP1000 and BP1000X names; check with Anker.
Is the C1000X loud?
Under heavy load or fast charging, yes: AppleInsider found its fans very loud. Lowering the charging speed in the app helps.
How much do they weigh?
28.44 lb each, per Anker US.
What warranty do they have?
5 years on both once registered with Anker, per Anker US.
