The Anker SOLIX C1000 and EcoFlow DELTA 2 need an exact-spec comparison before either can be called the better choice. The information available for this post describes two Anker models, so it can't verify the DELTA 2's capacity, output, charging or weight.
The original Anker SOLIX C1000 has 1,056Wh capacity, 1,800W output and 11 ports. Its C1000 Gen 2 sibling has slightly less capacity but higher output, so first decide which Anker model you mean when comparing it with the DELTA 2.
Anker SOLIX C1000 vs EcoFlow DELTA 2: what can you compare?
You can compare the Anker models' documented capacity, output, ports and charging claims, but a fair DELTA 2 comparison needs the same figures for its exact version. Don't infer a winner from brand names or a broad model family.
The original Anker SOLIX C1000 lists 1,056Wh capacity, 1,800W output, 2,400W surge output and 11 ports. It supports up to 600W of solar input.
Anker SOLIX C1000 Gen 2 lists 1,024Wh capacity, 2,000W output, 3,000W peak output and 10 ports. It also has a stated under-10-millisecond UPS switchover.
Those figures describe the two Anker units only. Check EcoFlow's specifications for the DELTA 2 you are considering, then compare capacity, continuous and surge output, port types, solar input and weight on equal terms.
Which unit has more capacity?
The original Anker SOLIX C1000 has 1,056Wh, while C1000 Gen 2 has 1,024Wh. The DELTA 2's capacity needs to be verified for the exact model before comparing it with either Anker.
A higher watt-hour figure can support a longer estimated runtime for the same device, but real runtime varies with the load and conversion losses. Anker's guidance for the original C1000 estimates AC runtime by multiplying 1,056Wh by 0.9, then dividing by the device's power use in watts.
For example, use the formula only as a rough estimate, not a promise. A device that cycles on and off, changes power draw or uses a different output type can affect the result.
If capacity around 1,000Wh is your main filter, our Best 1000wh Portable Power Station guide gives you a broader starting point. The Best Portable Power Station For 1000wh guide can also help compare options by intended use.
Does a higher watt-hour number settle the choice?
No. Capacity is only one part of the decision, and a station with more stored energy may still be a poor fit if its output is too low for your appliance or its ports don't match your gear.
Write down the devices you need to run, their wattage and how long you'll use each one. Then check both the station's continuous output and its surge limit, especially for appliances with motors.
Which has more output for demanding devices?
C1000 Gen 2 has the highest documented output of the two Anker models, at 2,000W continuous and 3,000W peak. The original C1000 provides 1,800W output and 2,400W surge output.
Output ratings help you screen appliances, but they don't tell you how long a battery will run them. Use the continuous rating for the device's normal draw and check the surge rating for startup needs.
Don't assume the EcoFlow DELTA 2 can handle a particular appliance based on a different DELTA model. Confirm the exact unit's limits and the appliance's startup requirements before relying on it for a planned use.
What should you check for a refrigerator or power tool?
Compare the device's running draw and startup demand with the station's stated output limits. If either figure is unknown, find it on the appliance label or in its manual before choosing a power station.
For a refrigerator, runtime also depends on how often its compressor runs and the conditions around it. For power tools, the load can change as you cut, drill or sand, so allow headroom instead of matching the rating exactly.
How do their charging claims compare?
Anker gives separate charging claims for its two C1000 models, but there isn't a verified EcoFlow DELTA 2 charging figure in this comparison. Compare AC recharge time, solar input and conditions for the exact DELTA 2 before treating one as faster.
Anker says the original C1000 can reach 80% in 43 minutes using UltraFast AC charging, with no load and an ambient temperature between 68°F and 122°F. Its solar input can reach 600W, with a stated full recharge time of 1.8 hours.
The C1000 Gen 2 has a 49-minute full-recharge claim using its HyperFlash technology. Anker says its solar recharge time is 1.8 hours with 600W input; the stated solar limit is 60V.
These times depend on setup and conditions. For Gen 2, Anker says UltraFast charging can slow when the battery cell temperature is between 0°C and 20°C.
Will solar charging work for your setup?
Check the station's voltage and current limits against the solar panel before connecting it. For the original C1000, Anker specifies an 11–60V solar charger with an XT-60 connector, with different current limits across the voltage range.
A panel's advertised wattage alone doesn't guarantee that it will charge at that rate. Confirm connector compatibility and the station's input limits, then account for sunlight, panel angle and shade when planning a recharge.
Which Anker model is easier to carry and connect?
The original C1000 offers 11 ports, while C1000 Gen 2 offers 10 and is described as smaller and lighter than similar models. For the EcoFlow DELTA 2, check the exact unit's dimensions and weight before deciding which is easier to move.
The original C1000 weighs 27.6 lb and measures 14.8 x 8.07 x 11.02 in. Gen 2 weighs 11.3 kg and measures 15.1 x 8.2 x 9.6 in.
The units use different stated weights, so convert them to the same unit when comparing. Also consider where the station will sit, how far you'll carry it and whether the cable connections are easy to reach in that spot.
Port count is useful, but check port types and power limits too. Eleven ports won't help if the devices you plan to connect need a port type the station doesn't have.
Which features matter for home backup?
C1000 Gen 2 has a stated under-10-millisecond UPS switchover, while the original C1000 is described for home use and outages. Confirm the DELTA 2's exact backup and UPS capabilities before using any station for equipment that needs uninterrupted power.
A UPS feature can matter for a desktop computer, router or other sensitive device, but switchover time isn't the only detail to check. Read the equipment manual and confirm that its power needs, connection method and backup requirements match the station.
For outage planning, make a list of essentials and estimate how long each must run. A power station's capacity does not guarantee that it can support every appliance in a home at once.
The C1000 Gen 2 also includes a Time-of-Use mode in the Anker app. That feature is aimed at managing charging and discharging around electricity price changes, which is separate from backup runtime.
How do the Anker C1000 models differ?
Choose the original C1000 for its extra 32Wh and one additional port; choose Gen 2 for higher output and its stated UPS switchover. These are Anker-to-Anker differences, not a verdict against the EcoFlow DELTA 2.
| Feature | Anker SOLIX C1000 | Anker SOLIX C1000 Gen 2 |
|---|---|---|
| Capacity | 1,056Wh | 1,024Wh |
| Output | 1,800W | 2,000W |
| Surge or peak output | 2,400W | 3,000W |
| Ports | 11 | 10 |
| Solar input claim | Up to 600W | 600W, 60V maximum |
| AC recharge claim | 80% in 43 minutes under stated conditions | Full charge in 49 minutes |
| Weight | 27.6 lb | 11.3 kg |
| UPS switchover | Not specified here | Under 10 ms |
The original C1000's recharge claim is for reaching 80%, while Gen 2's is for a full charge. They are not identical measures, so don't use those times as a direct speed ranking.

What should you verify before choosing the EcoFlow DELTA 2?
Match the exact EcoFlow DELTA 2 specifications to your device list before choosing it over either Anker. Focus on capacity, continuous and surge output, ports, solar input, recharge time, weight and backup features.
Model names can cover different versions or bundles. Check that the unit's name and included components match what you intend to buy, especially if a bundle includes solar panels or accessories.
Use the same checklist for the Anker and EcoFlow options:
- Capacity in watt-hours
- Continuous output and surge or peak output
- Number and type of ports
- Maximum solar input and voltage range
- AC charging time, including the percentage measured
- Weight and dimensions
- UPS or backup behavior, if needed
