Quick answers
- Is the Bluetti Apex 300 better than the EcoFlow DELTA Pro 3?
- EcoFlow DELTA Pro 3 takes capacity and output, Bluetti Apex 300 takes weight and noise — the decision is which of those you need, not overall quality. If neither is your constraint, the composite tiebreak goes to EcoFlow DELTA Pro 3 by 5 points — a hair, not a mandate.
- Which has more usable capacity, the Bluetti Apex 300 or EcoFlow DELTA Pro 3?
- The EcoFlow DELTA Pro 3, by 1,225 Wh — 2,565 Wh versus 3,790 Wh, a 48% advantage. At a 60 W load that is roughly 20.4 extra hours before the battery is empty. Both figures are independently measured AC-delivered energy — 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 3?
- The EcoFlow DELTA Pro 3: 3,840 W versus 4,000 W continuous. That gap matters only if a load sits between the two numbers — below 3,840 W both run it, above 4,000 W neither does. Surge headroom follows the same order: 7,680 W against 8,000 W, and surge is what decides whether a compressor or pump actually starts.
- How does runtime compare between the Bluetti Apex 300 and EcoFlow DELTA Pro 3?
- On the same sourced load — a refrigerator (full-size) — the EcoFlow DELTA Pro 3 runs longer: 60.2 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 3?
- The Bluetti Apex 300, by 13.5 kg (38 kg versus 51.5 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 3 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.
