Quick answers
- Is the Bluetti AC240 better than the Oupes Mega 2 Pro?
- Oupes Mega 2 Pro takes capacity and output, Bluetti AC240 takes recharge speed — the decision is which of those you need, not overall quality. If neither is your constraint, the composite tiebreak goes to Oupes Mega 2 Pro by 8 points — a hair, not a mandate.
- Which has more usable capacity, the Bluetti AC240 or Oupes Mega 2 Pro?
- The Oupes Mega 2 Pro, by 441 Wh — 1,300 Wh versus 1,741 Wh, a 34% advantage. At a 60 W load that is roughly 7.4 extra hours before the battery is empty. Both figures are estimated AC-delivered energy, not the nameplate battery rating — the watt-hours that actually reach your devices, which is always less than the number on the box.
- Which has more AC output, the Bluetti AC240 or Oupes Mega 2 Pro?
- The Oupes Mega 2 Pro: 2,400 W versus 2,500 W continuous. That gap matters only if a load sits between the two numbers — below 2,400 W both run it, above 2,500 W neither does. Surge headroom follows the same order: 3,600 W against 3,800 W, and surge is what decides whether a compressor or pump actually starts.
- How does runtime compare between the Bluetti AC240 and Oupes Mega 2 Pro?
- On the same sourced load — a refrigerator (full-size) — the Oupes Mega 2 Pro runs longer: 27.6 hours against 20.6. These are planning estimates from each model's AC-delivered capacity, not stopwatch tests; real duty cycle and temperature move them.
- Which is lighter, the Bluetti AC240 or Oupes Mega 2 Pro?
- The Oupes Mega 2 Pro, by 10.9 kg (22.1 kg versus 33 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 Oupes Mega 2 Pro for home backup, camping & rv. One model leads every use case we score here, which makes this an unusually clean choice.
