The catch
EcoFlow DELTA 3 Plus
Despite a similar 1kWh battery, its 1,800W continuous inverter is lower than the C1000 Gen 2’s. X-Boost leaves that normal output limit unchanged.
Side by side
EcoFlow DELTA 3 Plus vs Anker SOLIX C1000 Gen 2: Neither starts with more reserve, and Anker runs higher steady loads
Quick verdict
If battery expansion or two solar inputs matter to you, the DELTA 3 Plus is the one. If you carry the station often, or need a steady AC load between 1800W and 2000W, take the C1000 Gen 2. Each stores 1024Wh, so the Anker’s larger inverter adds no reserve and EcoFlow’s Plus name doesn’t signal a larger base battery.
Before you buy
Why, and what it costs you
The extra 200W can flip a once-clear appliance decision
Anker has 100W of rated total headroom at a steady 1900W, while EcoFlow is 100W over its rating.
Where this comes from
1900 − 1800 = 100W and 2000 − 1900 = 100W. Startup surge and individual outlet constraints are left out.
The catch
Anker SOLIX C1000 Gen 2
Gen 2 has no built-in light and, unlike the first-generation C1000, cannot take an expansion battery.
EcoFlow DELTA 3 Plus
- Why pick it
- Adding a compatible expansion battery later is in your plans.
- Two solar inputs with up to 1000W combined, or two 140W USB-C ports, are what you want.
- The catch
- Despite a similar 1kWh battery, its 1,800W continuous inverter is lower than the C1000 Gen 2’s. X-Boost leaves that normal output limit unchanged.
Anker SOLIX C1000 Gen 2
- Why pick it
- Continuous AC headroom beyond 1800W is a requirement.
- Saving 2.7 lb appeals to you, and fixed capacity is fine.
- The catch
- Gen 2 has no built-in light and, unlike the first-generation C1000, cannot take an expansion battery.

What this page compares
EcoFlow DELTA 3 Plus and Anker C1000 Gen 2 compared on expansion, two-input solar charging, carry weight and continuous appliance limits.
Anker favors carrying less and running a slightly larger steady load, whereas EcoFlow favors a growing solar setup.

In practice
Differences you will notice
The extra 200W can flip a once-clear appliance decision
Anker has 100W of rated total headroom at a steady 1900W, while EcoFlow is 100W over its rating.
How we worked this out
1900 − 1800 = 100W and 2000 − 1900 = 100W. Startup surge and individual outlet constraints are left out.
Total solar acceptance on EcoFlow is two thirds higher
Against Anker’s 600W ceiling, its 1000W combined ceiling is about 66.7% higher.
How we worked this out
(1000 − 600) ÷ 600 × 100 = 66.7%. To reach the combined maximum, EcoFlow needs input on both 500W channels.
Anker weighs nearly 10% less and gives up no nominal reserve
At 24.9 lb, it weighs about 9.8% less than the DELTA 3 Plus’s 27.6 lb.
How we worked this out
(27.6 − 24.9) ÷ 27.6 × 100 = 9.8%. Nominal base capacity stays at 1024Wh on both.
Option A
EcoFlow, DELTA 3 Plus
DELTA 3 Plus
This 1,024Wh station cares more about quick solar recovery and high-power USB-C than about headline battery size. Its two 500W solar inputs can each take a separate panel string.
- Best for
- Backup built around laptops, plus daily solar
Facts we checked
- A 1,024Wh LFP battery paired with 1,800W rated AC output
- Two 140W USB-C ports and sub-10ms transfer, at about 27.6 lb
- Supported expansion to roughly 5kWh, and two 500W solar inputs with 11–60V windows
Option B
Anker SOLIX, C1000 Gen 2
C1000 Gen 2
This 24.9-pound, 1,024Wh station has a 2,000W inverter, 140W USB-C and a 49-minute fast-charge mode that you switch on in the app.
- Best for
- As much usable output as a carryable 1kWh box allows
Facts we checked
- 2,000W rated AC output and 3,000W peak, with 1,024Wh LFP capacity
- A 140W USB-C port, at about 24.9 lb
- In UltraFast mode, a 49-minute advertised full AC recharge, plus 10ms transfer and 600W solar input
Spec by spec
Where they really differ
| Spec | EcoFlow DELTA 3 Plus | Anker SOLIX C1000 Gen 2 | In practice |
|---|---|---|---|
| Battery capacity | 1024Wh | 1024Wh | Both begin with the same nominal reserve. |
| Continuous AC output | 1800W | 2000W | Anker permits an additional 200W of steady combined demand. |
| Expansion battery support | Supported with compatible EcoFlow batteries | No expansion battery support | A route to longer reserve exists on EcoFlow. |
| Maximum solar input | 1000W across two 500W inputs | 600W through one input | A second independently controlled feed and more solar acceptance come with EcoFlow. |
| Listed weight | About 27.6 lb | 24.9 lb | Anker trims about 2.7 lb. |
| High-power USB-C | Two up to 140W | One up to 140W | An additional high-power USB-C connection is on EcoFlow. |
Trade-offs
What each pick costs you
With EcoFlow DELTA 3 Plus
- IP65 applies to the battery pack, so it isn’t a license to run the whole station in the rain. Expansion batteries and alternator hardware are sold separately.
With Anker SOLIX C1000 Gen 2
- To use the 49-minute mode you have to turn it on in the app, and it makes charging louder and draws more power.
Decision guide
How to decide
Let growth plans point you to EcoFlow and today’s load point you to Anker.
The 1900W load test is simple to read
A steady combined AC demand of 1900W is over the DELTA 3 Plus’s 1800W rating and under the C1000 Gen 2’s 2000W rating, so the Anker is the relevant choice for that job. Also check individual outlet ratings and startup demand. EcoFlow’s X-Boost mode doesn’t count as a substitute for the rated continuous supply.
EcoFlow’s advantage scales with the charging plan
The DELTA 3 Plus offers two solar inputs and compatible battery expansion, which together make sense for a system that will need more daily reserve and more time off-grid. The Anker stays at 1024Wh. If you always return home to recharge, you may never need those EcoFlow features and can put the lighter station first.
Matching capacity keeps the runtime question honest
Each battery holds 1024Wh. Absent comparable discharge testing, nominal specifications can’t hand either brand a runtime win. What separates them is the appliances they can support, the connections they offer and whether more battery can be added. Begin with those concrete needs, and then compare the current offers for the exact models.
What this page can’t tell you
- A solar ceiling guarantees neither constant input nor a recharge time.
- No ranking for measured efficiency or battery longevity is claimed here.
