These two have the same 1,024 Wh capacity, so the choice comes down to how you’ll use them. Pick the EcoFlow DELTA 3 Plus if you want more solar input or may add batteries later. Pick the Anker SOLIX C1000 Gen 2 if you want more standard AC output in a lighter box.
We set these 1 kWh stations side by side using published specs from November 2026. We haven’t tested them.

| AC output | 1,800 W | 2,000 W |
| Listed peak | 3,600 W surge with X-Boost | 3,000 W peak |
| Solar input | 1,000 W | 600 W |
| Full AC charge | 56 minutes | 49 minutes |
| Weight | 27.6 lb | 24.9 lb |
| Expandable | Up to 5 kWh | No |
| Battery rating | 4,000 cycles to 80% | 4,000 cycles to 80% |
| UPS switchover | Under 10 ms | Under 10 ms |
Where the DELTA 3 Plus wins
Solar: EcoFlow lists 1,000 W of solar input, compared with 600 W for the Anker. If you have the panels for it, you can refill the battery faster in limited sun.
Expansion: extra batteries can take it up to 5 kWh, while the Anker has no expansion option at all.
Car charging: EcoFlow lists a full charge in about 1.3 hours from an 800 W Alternator Charger. That’s a separate purchase, but it’s a strong option for van life.

- Capacity
- 1,024 Wh
- AC output
- 1,800 W
- Solar input

Strengths
- Expandable to 5 kWh
- 1,000 W of solar input
- Full charge in about 1.3 hours from an 800 W car source
Weaknesses
- Fast car charging needs a separate Alternator Charger
- 1 kWh base capacity is modest for full-time use
Where the C1000 Gen 2 wins
Standard output: 2,000 W is higher than the DELTA’s standard 1,800 W, which gives you more room for a coffee maker or microwave. EcoFlow’s X-Boost mode raises its listed output to 2,200 W, but the standard rating is the safer number to plan around.
Weight: it’s 2.7 lb lighter, which you’ll notice if you carry it often.
Cold use: Anker lists a discharge range down to -4°F. We couldn’t find an operating range on EcoFlow’s product page, so check the manual if this matters to you.

- Capacity
- 1,024 Wh
- AC output
- 2,000 W
- Solar input
- 600 W
- Weight
- 24.9 lb
Who it's for: People who want about 1 kWh and 2,000 W in a portable box, and don't need to add batteries.
Strengths
- 49-minute full AC charge
- 2,000 W output, 3,000 W peak
- Rated to keep 80% capacity after 4,000 cycles
Weaknesses
- Not expandable
- Lower solar input than the DELTA 3 Plus
Where they’re close
Both use batteries rated to keep 80% of their capacity after 4,000 cycles, and both list a UPS switchover of under 10 ms. Charging speeds are also close. Anker’s 49-minute figure uses its UltraFast mode, and EcoFlow’s 56-minute figure uses 1,500 W of AC input.
Noise figures are harder to compare. EcoFlow lists 30 dB and Anker lists 20 dB, but the two makers may not measure under the same conditions.
