Same battery, same 2,000W: compare the price tags, not the letters.
The Anker SOLIX C1000 Gen 2 and the Anker SOLIX C1000X Gen 2 share every headline figure Anker publishes: 1,024Wh of LFP rated for 4,000 cycles to 80%, 2,000W, a 10ms UPS, 600W of solar and a 49-minute wall refill. The X lists 9 ports instead of 10, a 1,500W wall input instead of 1,600W, and a car charging cable in the box. The Gen 2 has the full spec sheet, a published weight and five independent tests; the X has a thin US page and no test we could find. On paper the Gen 2 is the better documented of the two; the price section shows what separates them today.
Below: every difference we could document, a 20-second calculator for your own gear, seven modeled situations, an expandable third option, and what published tests found.
Same 1,024Wh battery, same 2,000W, same 10ms UPS and 600W solar input, prices $150 apart today. Anker lists 10 ports and a 1,600W input on the C1000 Gen 2, 9 ports and a 1,500W input on the C1000X Gen 2. Nothing we found makes the X the stronger unit.

The five differences, small as they are
The gaps between the two Anker US listings, with the better spec flagged. The 1,024Wh LFP battery, the 4,000-cycle rating, the 2,000W output, the 10ms UPS, the 600W solar input and the 49-minute wall refill are identical.
Will it run your setup? Check in 20 seconds
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 870Wh usable on each, from the same 1,024Wh battery; no independent test has measured the C1000X Gen 2.
Same battery, same runtime.
The C1000 Gen 2 and the C1000X Gen 2 both hold about 870Wh usable, so every appliance runs just as long on either one.Get our Black Friday alerts for Anker SOLIX

The price gap, in numbers
Same 1,024Wh battery: the Anker SOLIX C1000 Gen 2 costs $150 less than the Anker SOLIX C1000X Gen 2.
Prices refresh daily from Anker US.With the same battery and the same cycle rating, the gap pays for nothing we could find on Anker’s spec sheets: the C1000X Gen 2 lists one port fewer and a 100W slower input, and adds a car cable in the box. Anker US prices move often; the figures here are refreshed daily by our price engine.
The third option: the Anker SOLIX C1000 at $499.99
Anker SOLIX C1000: $499.99 today
The first-generation C1000 is the one in this family with a battery port: 1,056Wh and 1,800W from six outlets, 2,400W SurgePad, 600W of solar and a 58-minute refill, expandable to 2,112Wh with one BP1000, at 28.4 lb. It gives up 200W of output and the 10ms UPS rating, and is rated for 3,000 cycles against 4,000 for either Gen 2. Pick it if you want to add a second kWh later. Our C1000 vs C1000 Gen 2 comparison goes deeper. See the C1000 at Anker.
Seven modeled situations, worked out
Same formula as the calculator above: 85% of the rated capacity, no extra battery. With the same battery and inverter on paper, most situations tie: the ones that don’t are the point of this page.
24-hour outage, essentials only
A tie: about 9.5 hours each, an evening and a night. Neither takes an extra battery for a full day; the C1000 below does.
A 1,100W microwave
A tie: both run it within their 2,000W rating, with room for a fridge at the same time.
Home office through an outage
A tie, and both switch to battery in 10ms, faster than the roughly 16ms a desktop PC power supply rides through.
Five AC plugs at once
The C1000 Gen 2 has five AC outlets per Anker’s datasheet. Anker doesn’t list the C1000X Gen 2’s outlets; its product photo shows four, so plan on a power strip for the fifth device.
Refill from the wall before a storm
Anker’s figure for both. On the C1000X Gen 2 the 49 minutes needs UltraFlash switched on in the app; on the C1000 Gen 2, UltraFast only engages above 68°F of battery temperature, per Anker. OutdoorGearLab averaged about 1,100W from the wall on a C1000 Gen 2.
Refill from solar, each at its maximum
A tie: same 600W input on both, and Anker quotes 1.8 hours in optimal sun for each.
Carrying it
Anker gives 24.9 lb for the C1000 Gen 2 and OutdoorGearLab weighed 25.2 lb. The C1000X Gen 2 page gives no weight, only that it is 11% lighter than comparable units.
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 Gen 2 and C1000X Gen 2 weight, dimensions and full specifications
Weight: 24.9 lb for the Anker SOLIX C1000 Gen 2; Anker publishes no weight for the C1000X Gen 2. Dimensions: 15.1 × 8.2 × 9.6 in for the C1000 Gen 2; none published for the X. Everything else is in the sheet below.

07 · ChargingHow fast each one refills
Shorter bar, faster refill. Each row is scaled to its slower unit.
C1000 Gen 2: OutdoorGearLab averaged about 1,100W per hour from the wall, peaking just above 1,200WC1000X Gen 2: recharges from AC, solar, a car outlet, a generator or an alternator, per Anker
Our solar times assume panels deliver 70% of their rating; the brands’ figures assume ideal sun.
Every port, side by side
C1000 Gen 2
C1000X Gen 2
Practical consequence: the C1000 Gen 2 has five AC outlets, two USB-C, two USB-A and a 12V socket. Anker itemizes none of the C1000X Gen 2’s 9 ports; its product photo shows four AC outlets. If you need a fifth AC plug, the Gen 2 has it.
09 · NoiseNoise: C1000 Gen 2 vs C1000X Gen 2
Both are quiet at light loads by Anker’s account: 20dB for the Anker SOLIX C1000 Gen 2, 0 to 20dB under 200W for the Anker SOLIX C1000X Gen 2. Only the Gen 2 has been measured under load: about 45dB at 1 m (Notebookcheck).
Anker’s figures give no distance; no published test has measured the X.Every figure we found, with its source
What reviewers heard: Near maximum wattage the fan gets frustratingly loud (OutdoorGearLab); fans kick on loudly at very high charging rates (CleanTechnica).
Measured by a tester Brand figure
- Charge during the day, or lower the charging speed in the Anker app overnight.
Cold and heat: C1000 Gen 2 vs C1000X Gen 2
The Anker SOLIX C1000 Gen 2 charges from 32°F to 104°F and runs from −4°F to 104°F, per Anker. Anker publishes no range for the Anker SOLIX C1000X Gen 2.
Figures from Anker US for the C1000 Gen 2; none published for the C1000X Gen 2.- Charge either one indoors in winter: the C1000 Gen 2 doesn’t charge below 32°F, and Anker publishes no range for the X.
- On the C1000 Gen 2, UltraFast charging only engages above 68°F; between 32°F and 68°F it charges much more slowly (Anker).
App, UPS and smart features
Same UPS and the same fast refill: the Anker SOLIX C1000 Gen 2 and the Anker SOLIX C1000X Gen 2 both switch in 10ms and refill in 49 minutes. Anker documents more app features for the Gen 2.
Neither takes an extra battery.Green zone: a switch under about 16ms, which most desktop PCs ride through without restarting.
Can you add a battery later? Anker dropped the battery port from the Anker SOLIX C1000 Gen 2; the Anker SOLIX C1000X Gen 2 page lists none.
Can it charge off-peak? Anker lists a Time-of-Use mode for the Anker SOLIX C1000 Gen 2; the Anker SOLIX C1000X Gen 2 page doesn’t mention one.
How does the app connect? The Anker SOLIX C1000 Gen 2 connects over Wi-Fi or Bluetooth; the Anker SOLIX C1000X Gen 2 page mentions remote monitoring in the Anker app without naming the connection.
Does it work as a UPS? Both switch to battery in 10ms per Anker, faster than the roughly 16ms a desktop PC power supply rides through.
Does it have a fast charging mode? The Anker SOLIX C1000 Gen 2 reaches 49 minutes with UltraFast above 68°F of battery temperature; the Anker SOLIX C1000X Gen 2 needs UltraFlash switched on in the Anker app.
Warranty and support
Same 5 years once registered: Anker’s US registration page covers the Anker SOLIX C1000 Gen 2 and the Anker SOLIX C1000X Gen 2. Neither product page states the term in its specs.
Same coverage. Register the day it arrives.Subject to each brand’s warranty terms and eligibility.
Anker rates both at 4,000 cycles to 80% capacity, about 11 years at one full cycle a day. Calendar aging and heat also reduce capacity, so read the rating as a ceiling.
- Register either one with Anker when it arrives and keep proof of purchase: Anker’s registration page says that activates the 5-year coverage.
What reviewers report
We have not lab-tested these two units. Here is what 5 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
- Neither takes an extra battery. 1,024Wh is the ceiling; the C1000 below has a battery port.
- Anker doesn’t itemize the C1000X Gen 2’s ports. Count the outlets on the unit you buy if you need five.
- The C1000X Gen 2 page gives no weight, size or temperature range. Ask the seller before you plan around them.
- The 49-minute refill needs a fast mode on both: UltraFlash in the app on the X, UltraFast above 68°F on the Gen 2.
- Both stop at 2,000W. A microwave and a coffee maker together overload them.
- Neither ships with a solar cable, per the Anker box lists.
- Neither charges below freezing on the C1000 Gen 2’s published range; Anker publishes none for the X, so charge it indoors in winter too.
- C1000 Gen 2, per its US documentation: UltraFast charging only activates when battery temperature is above 68F (20C); charging at 32-68F is significantly slower.
- C1000 Gen 2, per its US documentation: USB-A and USB-C1 share a 20W total limit; only USB-C2 reaches 140W.
- C1000 Gen 2, per its US documentation: Not expandable; Anker recommends the original C1000 for users who need extra capacity.
- C1000 Gen 2, per its US documentation: Normal AC charging 1,200W max; AC bypass 1,800W max; solar 600W, 60V max.
- C1000X Gen 2, per its US documentation: The 0-20dB quiet claim applies only under 200W load.
Frequently asked questions
