The differences that matter
- Capacity 1.056 kWh vs 2.048 kWh → with the expansion the Anker reaches 2.112 kWh, the same as the EcoFlow; the EcoFlow gets there with nothing added.
- Peak output 2400 W vs 4800 W → for appliances with a demanding start-up the EcoFlow has twice the declared margin.
- Maximum charge power 1.3 kW vs 2.3 kW → in theory, without losses and at full power, both fill in about 50 minutes: one because it is smaller, the other because it charges harder.
- Warranty 5 years vs 3 → at one cycle a day the cover lasts 1825 cycles vs 1095.
Which one to choose
Choose Anker SOLIX C1000 if…
you want a 12.9 kg unit with longer cover, declared to work from -20 to 40 °C with solar input up to 600 W, and 1 kWh is enough to start with. You accept a lower peak margin and having to add the expansion to grow.
Choose EcoFlow DELTA 3 Max if…
you need the full capacity from day one and have loads with demanding start-ups; declared switchover is 10 ms and noise 25 dB. You accept carrying 20.3 kg and a shorter warranty.
