Anker SOLIX C1000 Gen 2 vs EcoFlow DELTA 3 Plus: backup power comparison
The Anker SOLIX C1000 Gen 2 and EcoFlow DELTA 3 Plus each list 1,024 Wh capacity, 90% usable capacity, LiFePO4 chemistry, 4,000-cycle life and a five-year warranty. The Anker provides higher continuous output at 2,000 W and weighs less at 11.3 kg; the EcoFlow lists a higher surge rating of 3,600 W.
The EcoFlow lists greater solar input at 1,000 W and supports up to 5,000 Wh of expansion, while the Anker lists 600 W solar input and no expansion capacity. Supplied data includes no prices or actual load requirements, so a value judgment or workload-specific winner is not possible.
- Choose based on output: The Anker’s 2,000 W continuous rating favors higher sustained loads, while the EcoFlow’s 3,600 W surge rating may better suit loads with higher startup demand.
- Choose based on recharging and growth: The EcoFlow has the higher solar-input rating and listed expansion support; the Anker lists faster AC charging at 1,600 W versus 1,500 W.
- Check the missing context: Both list UPS functionality with a 10 ms transfer time, but the evidence does not provide prices or your appliance loads, so cost-per-Wh and runtime comparisons are insufficient.
This comparison uses current Backup Power IQ specification and offer data. It is designed to show measurable tradeoffs rather than declare a universal winner.

Price and value context
Those figures are not enough by themselves: inverter output, motor surge, solar acceptance, weight and expansion support can matter more than raw $/Wh for a particular outage plan.
