Comparison

Anker SOLIX C1000 Gen 2 vs EcoFlow DELTA 3 Plus

Both store exactly 1,024 Wh in LiFePO4 cells with a 10 ms class UPS. The Anker SOLIX C1000 Gen 2 has more output (2,000 W), faster wall charging and is lighter, while the EcoFlow DELTA 3 Plus wins if you want to add batteries later or charge from a lot of solar.

Runtime example with a fridge and Wi-Fi

Using the same method as our power station runtime calculator, a full size fridge at 150 W for 12 hours a day plus a 20 W router all day is 2,280 Wh a day (about 95 W on average). With 85% inverter efficiency and a 10% reserve, here is how long each lasts.

  • Anker SOLIX C1000 Gen 2 (1,024 Wh) lasts about 8 h 15 min
  • EcoFlow DELTA 3 Plus (1,024 Wh) lasts about 8 h 15 min

Covering a full day of that load needs about 2,980 Wh, so for longer outages plan on solar recharging, an expandable model or a second unit. Plug in your own appliances in the calculator for a personal figure.

Frequently asked questions

Do the Anker SOLIX C1000 Gen 2 and EcoFlow DELTA 3 Plus have the same capacity?

Yes. Both makers list 1,024 Wh of LiFePO4 capacity rated for 4,000 cycles to 80%. The differences are output, charging speed, solar input, expansion and weight.

Which charges faster?

Anker lists a full charge in 49 minutes at 1,600 W with UltraFast mode switched on in its app. EcoFlow lists 0 to 100% in 56 minutes at 1,500 W for the DELTA 3 Plus.

Can I add a battery to the Anker SOLIX C1000 Gen 2?

No. Anker says the C1000 Gen 2 drops expansion to save size and weight, and recommends the original C1000 if you need expandable capacity. The DELTA 3 Plus expands to 5 kWh with EcoFlow extra batteries.

How long would each run a fridge and router?

They share the same 1,024 Wh, so with our calculator method (fridge 150 W for 12 hours a day, 20 W router, 85% efficiency, 10% reserve) both last about 8 hours. Try your own appliances in our runtime calculator.
