Quick answers
- Is the Aferiy P280 better than the EcoFlow DELTA 3 Max Plus (2048Wh)?
- Aferiy P280 is the better station: the overall scores are close, but it wins recharge speed, weight and noise — every dimension that separates them.
- Which has more usable capacity, the Aferiy P280 or EcoFlow DELTA 3 Max Plus (2048Wh)?
- Neither, in any way you would notice: 1,741 Wh against 1,741 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 Aferiy P280 or EcoFlow DELTA 3 Max Plus (2048Wh)?
- The EcoFlow DELTA 3 Max Plus (2048Wh): 2,800 W versus 3,000 W continuous. That gap matters only if a load sits between the two numbers — below 2,800 W both run it, above 3,000 W neither does. Surge headroom follows the same order: 5,600 W against 6,000 W, and surge is what decides whether a compressor or pump actually starts.
- How does runtime compare between the Aferiy P280 and EcoFlow DELTA 3 Max Plus (2048Wh)?
- They run within 0% of each other on the same load — about 27.6 hours each on a refrigerator (full-size). Runtime will not separate these two; the deciding factor is somewhere else.
- Which is lighter, the Aferiy P280 or EcoFlow DELTA 3 Max Plus (2048Wh)?
- They are effectively the same to carry — 21.6 kg against 22.1 kg. Neither is meaningfully easier to move, so portability should not decide this one.
- Which model should I buy for my use case?
- On the sub-scores that describe each use case: the Aferiy P280 for home backup, camping & rv. One model leads every use case we score here, which makes this an unusually clean choice.
