Where these rank

Quick answers

Is the Bluetti Elite 30 V2 better than the Marbero M823?
Bluetti Elite 30 V2 leads by 37 points overall. No price call today — the performance leader has no tracked street price yet.
Which has more usable capacity, the Bluetti Elite 30 V2 or Marbero M823?
The Bluetti Elite 30 V2, by 39 Wh — 220 Wh versus 181 Wh, a 22% advantage. At a 60 W load that is roughly 0.7 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 Elite 30 V2 or Marbero M823?
The Bluetti Elite 30 V2: 600 W versus 300 W continuous. That gap matters only if a load sits between the two numbers — below 300 W both run it, above 600 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 Bluetti Elite 30 V2 and Marbero M823?
On the same sourced load — a refrigerator (full-size) — the Bluetti Elite 30 V2 runs longer: 3.5 hours against 2.9. 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 Elite 30 V2 or Marbero M823?
The Marbero M823, by 2.2 kg (2.1 kg versus 4.3 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 Bluetti Elite 30 V2 for home backup; the Marbero M823 for camping & rv. They split, so the honest answer depends on which of those you are actually buying for.
