Choose the C1000 Gen 2 for higher output and a stated 49-minute full recharge, or the original C1000 if expansion matters. The name “C1000X” is unclear, so check the exact model name and number before buying.
The original Anker SOLIX C1000 has 1,056Wh of capacity, 1,800W output and 2,400W surge output. For another compact-station comparison, see EcoFlow DELTA 3 models.
The C1000 Gen 2 has 1,024Wh, 2,000W output and 3,000W peak output.
Gen 2 adds output and UPS backup, while Anker recommends the original C1000 for buyers who need expansion. For a closer look at the original, see our Anker SOLIX C1000 review.
Anker SOLIX C1000 vs C1000X: what is the model difference?
The confirmed models are the original C1000, model A1761, and C1000 Gen 2, model A1763. The name “C1000X” is not established here as a separate model.
These models have different output, charging and expansion features. If a product is called “C1000X,” compare its model number with A1761 or A1763 before relying on a feature claim.
The original is named Anker SOLIX C1000 Portable Power Station, while Gen 2 is named Anker SOLIX C1000 Gen 2 Portable Power Station. The “X” could be a seller shorthand or an error, so use the model number to identify the unit.
Which one gives you more power?
The C1000 Gen 2 provides higher output, while the original C1000 has 32Wh more capacity. For another model comparison, see OUPES Mega 1 models.
Choose based on the devices you need to run and for how long.
The original C1000 is rated for 1,800W output with 2,400W surge. Gen 2 provides 2,000W output and 3,000W peak output.
Capacity is close: 1,056Wh for the original and 1,024Wh for Gen 2. Actual runtime depends on device load, and AC use loses some energy through inverter conversion.
Anker SOLIX C1000X vs C1000 for appliances
Gen 2's higher peak output may help with a device that has a high startup draw, but check the device's running and startup wattage. Don't assume every appliance will work just because its running watts fall below the station's output rating.
The original C1000's output is 1,800W, with 2,400W surge output. Match the station to the appliance label and its startup needs before choosing.
Our guide to what you can use the Anker SOLIX C1000 for helps you consider device loads and use cases.
How do charging speeds compare?
Gen 2 has a stated full AC recharge time of 49 minutes; the original can reach 80% in 43 minutes under specific conditions. These figures use different endpoints, so they don't show that one always charges faster.
The original's 43-minute figure assumes UltraFast mode, no load and an ambient temperature between 68–122°F. The Anker app is required to enable UltraFast AC charging.
Gen 2's stated 49-minute full recharge is at 1,600W with HyperFlash enabled in the Anker app. Anker says charging can slow when the battery cell is below 20°C.
Both models support up to 600W solar charging and have a stated 1.8-hour full solar recharge time. Solar conditions and setup affect real charging time.
Does Gen 2's extra output cost you expansion?
Yes, the C1000 Gen 2 has no battery expansion feature, while Anker recommends the original C1000 for buyers who need expansion. This difference may matter more than Gen 2's higher output if your future capacity needs are uncertain.
Anker says Gen 2's expansion feature was removed to reduce weight and size. Its capacity is 1,024Wh.
The original C1000 is the fit to consider if expansion is a key requirement. For a larger Anker system, see the F3800 vs F3800 Plus comparison.
Confirm the expansion options for the exact model before buying.
Which station is easier to move and use?
Gen 2 is 14% smaller and 11% lighter than similar models, while the original C1000 weighs 27.6 lb. Gen 2 weighs about 11.3 kg and measures 15.1 x 8.2 x 9.6 in.
Anker describes the original C1000 as 15% smaller than comparable 1kWh units. It measures 14.8 x 8.07 x 11.02 in.
These size comparisons use different reference groups, so they don't show which station is smaller than the other. Compare the dimensions with your storage space and consider whether you can comfortably lift the unit.
The original has 11 ports, while Gen 2 has 10 ports. Check the device connections you need before choosing.
For models with several AC outlets, compare Anker power stations with AC outlets.
What should you choose for backup power?
Choose Gen 2 if higher output and UPS switchover matter; choose the original if expansion is more important. Check your equipment's power draw and the station's operating instructions.
Gen 2 has a stated 10 ms UPS switchover and is described for equipment such as CPAP machines and laptops. Check the equipment manufacturer's instructions to confirm whether this feature suits your specific setup.
The original C1000 is described for home use and power outages, and it has the higher stated capacity. Capacity alone doesn't tell you how long your specific backup setup will run.

Which Anker SOLIX C1000 should you choose?
Pick Gen 2 for higher output and UPS backup; pick the original C1000 if expansion and slightly higher capacity matter more. If a unit is called “C1000X,” verify whether its model number is A1761 or A1763.
Compare device wattage, startup draw, required runtime and charging options to decide which one suits your needs. For smaller USB-focused models, compare Anker DC power stations.
