EcoFlow DELTA 3 Plus vs Anker SOLIX C1000 Gen 2
EcoFlow DELTA 3 Plus (1,024 Wh, 1,800 W) vs Anker SOLIX C1000 Gen 2 (1,024 Wh, 2,000 W). Their batteries are about the same size, so the differences are in output, charging and features. Here is where each one comes out ahead, based on the manufacturers' published specs.
Each row has its own scale, and the longer bar fills the row. Figures are the manufacturers' published specs.
Choose the DELTA 3 Plus for…
- faster solar charging: up to 1,000 W vs 600 W of panels
- room to grow: expands to 5,120 Wh with extra batteries
- starting pumps and compressors: 3,600 W vs 3,000 W surge
Choose the C1000 Gen 2 for…
- high-power appliances: 2,000 W vs 1,800 W continuous output

Our verdict
Same battery, same runtime. Both hold 1,024 Wh, so in our calculator a typical fridge gets about 15 hours from either one and a CPAP about 29. What separates them is everything around the battery.
The Anker is the lighter, quicker-charging one. It weighs 24.9 lb to the EcoFlow's 27.6, fills from the wall in about 49 minutes at its fastest setting, and is rated for 2,000 W continuous, 200 W more than the DELTA 3 Plus. If it's going to live in a closet and come out for outages, that's a tidy package.
We'd lean toward the DELTA 3 Plus if solar is part of the plan, or if there's any chance you'll outgrow 1 kWh. It takes 1,000 W of panels against 600 W, and it can add EcoFlow extra batteries up to 5,120 Wh. The C1000 Gen 2 can't be expanded at all. The EcoFlow also has the higher surge rating (3,600 W against 3,000 W), which helps with a sump pump or an older fridge that kicks hard when it starts.
Both switch over in 10 ms and both come with a 5-year warranty. One gap: Anker doesn't publish how many AC outlets the Gen 2 has, so make sure it has enough plugs for your setup before you order.
How we compared: the makers' published specs plus our runtime calculations. We haven't bench-tested these units ourselves.
