Quick answers

Is the Dabbsson 1000L better than the EcoFlow DELTA 3?
EcoFlow DELTA 3 leads by 21 points overall.
Which has more usable capacity, the Dabbsson 1000L or EcoFlow DELTA 3?
Neither, in any way you would notice: 857 Wh against 870 Wh is a 1.5% 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 Dabbsson 1000L or EcoFlow DELTA 3?
The EcoFlow DELTA 3: 1,200 W versus 1,800 W continuous. That gap matters only if a load sits between the two numbers — below 1,200 W both run it, above 1,800 W neither does. Surge headroom follows the same order: 2,400 W against 3,600 W, and surge is what decides whether a compressor or pump actually starts.
How does runtime compare between the Dabbsson 1000L and EcoFlow DELTA 3?
They run within 1.5% of each other on the same load — about 13.6 hours each on a refrigerator (full-size). Runtime will not separate these two; the deciding factor is somewhere else.
Which is lighter, the Dabbsson 1000L or EcoFlow DELTA 3?
The Dabbsson 1000L, by 1.9 kg (10.6 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 model should I buy for my use case?
On the sub-scores that describe each use case: the EcoFlow DELTA 3 for home backup; the Dabbsson 1000L for camping & rv. They split, so the honest answer depends on which of those you are actually buying for.
