Quick answer: The Anker SOLIX C1000 has 32Wh more nominal capacity (1,056Wh vs. 1,024Wh); both list 1,800W continuous AC output; the EcoFlow DELTA 3 Plus is lighter (27.6 lb vs. 28.44 lb). At a steady 300W load our model estimates 2.6 h for the EcoFlow DELTA 3 Plus and 2.6 h for the Anker C1000. There is no universal winner: your loads, charging plan and the price of equivalent bundles decide.
Where they differ
Choose the EcoFlow DELTA 3 Plus if…
- you start motors or compressors (surge 3,600W published)
- you plan to recharge from solar (1,000W max input vs. 600W)
- you use it as a UPS for sensitive equipment (<10 ms switchover)
Choose the Anker SOLIX C1000 if…
- none of the published numbers above clearly favors it, so choose it if the delivered price, availability, app or support suits you better
Check your own loads
Capacity decides how long; continuous output decides what can run at once; surge decides whether motors and compressors start. Put your appliances into the tools below with either model preselected, and compare delivered prices for equivalent bundles before you buy.
