Quick answers

Is the Anker SOLIX C1000 Gen 2 better than the EcoFlow DELTA 3 Plus?
EcoFlow DELTA 3 Plus takes capacity and output, Anker SOLIX C1000 Gen 2 takes weight and noise — the decision is which of those you need, not overall quality. If neither is your constraint, the composite tiebreak goes to EcoFlow DELTA 3 Plus by 4 points — a hair, not a mandate.
Which has more usable capacity, the Anker SOLIX C1000 Gen 2 or EcoFlow DELTA 3 Plus?
Neither, in any way you would notice: 870 Wh against 870 Wh is a 0% 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 C1000 Gen 2 or EcoFlow DELTA 3 Plus?
The Anker SOLIX C1000 Gen 2: 2,000 W versus 1,800 W continuous. That gap matters only if a load sits between the two numbers — below 1,800 W both run it, above 2,000 W neither does. Surge headroom follows the same order: 3,000 W against 3,600 W, and surge is what decides whether a compressor or pump actually starts.
How does runtime compare between the Anker SOLIX C1000 Gen 2 and EcoFlow DELTA 3 Plus?
They run within 0% of each other on the same load — about 13.8 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 C1000 Gen 2 or EcoFlow DELTA 3 Plus?
The Anker SOLIX C1000 Gen 2, by 1.2 kg (11.3 kg versus 12.5 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 C1000 Gen 2 or EcoFlow DELTA 3 Plus?
The Anker SOLIX C1000 Gen 2: 49 minutes from empty to full against 56 minutes, a difference of 7 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 Plus for home backup; the Anker SOLIX C1000 Gen 2 for camping & rv. They split, so the honest answer depends on which of those you are actually buying for.
