Anker SOLIX C1000 Gen 2 vs EcoFlow DELTA 3 Plus
Both start at 1,024Wh. This is a close capacity match for portable appliance backup; the decision is output headroom versus expansion.
The short answer: Choose the C1000 Gen 2 for more continuous output from the same rated battery capacity. Choose the DELTA 3 Plus if adding a compatible extra battery later matters more. Neither starts with a runtime advantage on capacity alone.
Choose EcoFlow DELTA 3 Plus if…
You need no more than 1,800W continuous output and want a compatible expansion-battery path.

Charging figures are manufacturer limits or claims, not our measured recharge times. Mode, temperature, state of charge and input supply affect actual charging.
What the difference means at home
For a steady 1,900W load, the Anker has the higher suitable nameplate rating; the EcoFlow exceeds its normal continuous rating. At a modest 100W load, their identical rated capacity does not establish which lasts longer: inverter losses and idle draw decide that.
Read this before choosing
The original C1000 is a different, expandable model. Do not buy its expansion battery for the C1000 Gen 2. EcoFlow X-Boost is not the same as its normal 1,800W continuous rating.
Check each outlet’s current limit as well as the total output. Capacity alone cannot predict actual AC runtime: load, idle draw, conversion losses, temperature and battery condition all matter. Use our refrigerator calculator for an estimate with explicit assumptions.

Compare the same base unit and included accessories. A solar-panel bundle or extra battery changes the total price and capacity. We do not name a price winner without a current like-for-like quote.
