Quick answers

Is the Anker SOLIX C2000 Gen 2 better than the EcoFlow DELTA 3 Max?
These two match on everything except warranty and track record, and that goes to Anker SOLIX C2000 Gen 2.
Which has more usable capacity, the Anker SOLIX C2000 Gen 2 or EcoFlow DELTA 3 Max?
Neither, in any way you would notice: 1,761 Wh against 1,741 Wh is a 1.1% gap, which is smaller than the swing you get from running the same load on a cold morning. Treat them as the same size and decide on output, weight, or today's price instead. Both figures are estimated AC-delivered energy, not the nameplate battery rating — the watt-hours that actually reach your devices.
Which has more AC output, the Anker SOLIX C2000 Gen 2 or EcoFlow DELTA 3 Max?
Neither — both are rated 2,400 W continuous, so any load one can run, the other can too. Surge headroom follows the same order: 4,000 W against 4,800 W, and surge is what decides whether a compressor or pump actually starts.
How does runtime compare between the Anker SOLIX C2000 Gen 2 and EcoFlow DELTA 3 Max?
They run within 1.1% of each other on the same load — about 28 hours each on a refrigerator (full-size). Runtime will not separate these two; the deciding factor is somewhere else.
Which is lighter, the Anker SOLIX C2000 Gen 2 or EcoFlow DELTA 3 Max?
The Anker SOLIX C2000 Gen 2, by 1.4 kg (18.9 kg versus 20.3 kg). Both weights are manufacturer figures for the bare unit; cables and a solar panel add to whatever you actually carry.
Which recharges faster from the wall, the Anker SOLIX C2000 Gen 2 or EcoFlow DELTA 3 Max?
The EcoFlow DELTA 3 Max: 68 minutes from empty to full against 88 minutes, a difference of 20 minutes. This matters most between outages and during a short grid window — if you only ever recharge overnight, it does not matter at all.
Which model should I buy for my use case?
On the sub-scores that describe each use case: the EcoFlow DELTA 3 Max for home backup; the Anker SOLIX C2000 Gen 2 for camping & rv. They split, so the honest answer depends on which of those you are actually buying for.
