Where these rank
- EcoFlow DELTA Pro 3 #1 of 10 in Best for RV & Van Life · #2 XL / home backup in Best Portable Power Stations

Quick answers
- Is the EcoFlow DELTA Pro 3 better than the Zendure SuperBase V6400?
- EcoFlow DELTA Pro 3 leads by 30 points overall.
- Which has more usable capacity, the EcoFlow DELTA Pro 3 or Zendure SuperBase V6400?
- The Zendure SuperBase V6400, by 1,682 Wh — 3,790 Wh versus 5,472 Wh, a 44% advantage. At a 60 W load that is roughly 28 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 EcoFlow DELTA Pro 3 or Zendure SuperBase V6400?
- The EcoFlow DELTA Pro 3: 4,000 W versus 3,800 W continuous. That gap matters only if a load sits between the two numbers — below 3,800 W both run it, above 4,000 W neither does. Surge headroom follows the same order: 8,000 W against 5,000 W, and surge is what decides whether a compressor or pump actually starts.
- How does runtime compare between the EcoFlow DELTA Pro 3 and Zendure SuperBase V6400?
- On the same sourced load — a refrigerator (full-size) — the Zendure SuperBase V6400 runs longer: 86.9 hours against 60.2. These are planning estimates from each model's AC-delivered capacity, not stopwatch tests; real duty cycle and temperature move them.
- 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. One model leads every use case we score here, which makes this an unusually clean choice.
