Quick answers
- Is the Bluetti Apex 300 better than the EcoFlow DELTA Pro Ultra X?
- EcoFlow DELTA Pro Ultra X leads by 9 points overall.
- Which has more usable capacity, the Bluetti Apex 300 or EcoFlow DELTA Pro Ultra X?
- The EcoFlow DELTA Pro Ultra X, by 7,880 Wh — 2,565 Wh versus 10,445 Wh, a 307% advantage. At a 60 W load that is roughly 131.3 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 Apex 300 or EcoFlow DELTA Pro Ultra X?
- The EcoFlow DELTA Pro Ultra X: 3,840 W versus 12,000 W continuous. That gap matters only if a load sits between the two numbers — below 3,840 W both run it, above 12,000 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 Bluetti Apex 300 and EcoFlow DELTA Pro Ultra X?
- On the same sourced load — a refrigerator (full-size) — the EcoFlow DELTA Pro Ultra X runs longer: 165.8 hours against 40.7. 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 Apex 300 or EcoFlow DELTA Pro Ultra X?
- The Bluetti Apex 300, by 97.5 kg (38 kg versus 135.5 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 Pro Ultra X for home backup; the Bluetti Apex 300 for camping & rv. They split, so the honest answer depends on which of those you are actually buying for.
