DJI Power 2000 vs Oupes Mega 2 Pro
Decision readout
Better station
DJI Power 2000 takes weight and noise, Oupes Mega 2 Pro takes recharge speed — the decision is which of those you need, not overall quality. If neither is your constraint, the composite tiebreak goes to DJI Power 2000 by 6 points — a hair, not a mandate.

Where these rank
Quick answers
- Is the DJI Power 2000 better than the Oupes Mega 2 Pro?
- DJI Power 2000 takes weight and noise, Oupes Mega 2 Pro takes recharge speed — the decision is which of those you need, not overall quality. If neither is your constraint, the composite tiebreak goes to DJI Power 2000 by 6 points — a hair, not a mandate.
- Which has more usable capacity, the DJI Power 2000 or Oupes Mega 2 Pro?
- 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 DJI Power 2000 or Oupes Mega 2 Pro?
- The DJI Power 2000: 3,000 W versus 2,500 W continuous. That gap matters only if a load sits between the two numbers — below 2,500 W both run it, above 3,000 W neither does. Neither model publishes a surge figure we can source, so startup capability is unresolved here — check it before planning around a motor or compressor load.
- How does runtime compare between the DJI Power 2000 and Oupes Mega 2 Pro?
- 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 DJI Power 2000 or Oupes Mega 2 Pro?
- They are effectively the same to carry — 22 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 DJI Power 2000 for home backup, camping & rv. One model leads every use case we score here, which makes this an unusually clean choice.
