Anker SOLIX C1000 Gen 2 vs EcoFlow DELTA 3
Updated October 15, 2026
Short answer: we’d pick the Anker if you’ll recharge from solar a lot, and the DELTA 3 if you think you’ll want more capacity later.
Both hold 1,024Wh, so runtime on the same load is the same. Where they part ways is the inverter, the solar input and expansion.

When we’d pick the Anker SOLIX C1000 Gen 2
The SOLIX C1000 Gen 2 has a 2,000W inverter and 600W of solar input, both higher than the DELTA 3. It’s also lighter at 24.9 lb, and the two 140W USB-C ports are handy if you charge a big laptop.
When we’d pick the EcoFlow DELTA 3
The DELTA 3 is the one that grows. EcoFlow lists extra batteries up to 5 kWh, and the C1000 Gen 2 doesn’t take an expansion battery at all.
Worth knowing: neither has a 30A RV socket, so for an RV shore cable you’d look at the AC200PL instead.
