Anker SOLIX C1000 Gen 2 vs EcoFlow DELTA 3
Anker SOLIX C1000 Gen 2
EcoFlow DELTA 3The C1000 Gen 2 delivers 11% more continuous output, and that is the gap worth deciding on: it reaches appliances the other one cannot start. They are level on capacity, wall recharge time and rated cycle life. Scored across this catalogue they land at 7.0 and 6.7 out of 10.

The rows worth your attention are the ones where the gap is large enough to change a decision. On this pair that means AC output and weight. Everything else is close enough to ignore.
Where they really separate: AC output
This is the one gap large enough to decide the question. The C1000 Gen 2 comes out 11% ahead on AC output, and the reason that matters is practical rather than arithmetic.
Continuous output is the wall you hit first. It decides what will start at all, and no amount of extra capacity gets you past it.
The other differences, in order of size
- Weight. The C1000 Gen 2 leads by 11%.
- Maximum solar input. The C1000 Gen 2 leads by 20%.
None of these is decisive on its own. Taken together they describe two units built to slightly different briefs, which is worth knowing before you choose on the headline figure alone.
What each one will run
Same arithmetic for both: usable watt hours after an assumed 85% inverter efficiency, divided by average draw rather than peak.

Common questions
Is the C1000 Gen 2 or the DELTA 3 better value?
This site does not print prices, because a stale price is worse than none. Check both on Amazon, then weigh the gap against the differences above. A 11% lead on AC output is worth paying for only if that axis matters to your use.
Can I compare their surge ratings directly?
Not always. BLUETTI's Lifting Power and EcoFlow's X-Boost run appliances above rated output by lowering voltage, which suits a kettle or a heater but not a motor or a computer. A conventional surge rating means something else: a brief tolerance for start-up current. The table keeps each maker's own label attached.
