Where these rank

Quick answers
- Is the Aferiy P280 better than the VTOMAN FlashSpeed 1500?
- Aferiy P280 leads by 24 points overall. No price call today — the performance leader has no tracked street price yet.
- Which has more usable capacity, the Aferiy P280 or VTOMAN FlashSpeed 1500?
- The Aferiy P280, by 383 Wh — 1,567 Wh versus 1,184 Wh, a 32% advantage. At a 60 W load that is roughly 6.4 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 Aferiy P280 or VTOMAN FlashSpeed 1500?
- The Aferiy P280: 2,800 W versus 1,500 W continuous. That gap matters only if a load sits between the two numbers — below 1,500 W both run it, above 2,800 W neither does. Surge headroom follows the same order: 5,600 W against 3,000 W, and surge is what decides whether a compressor or pump actually starts.
- How does runtime compare between the Aferiy P280 and VTOMAN FlashSpeed 1500?
- On the same sourced load — a refrigerator (full-size) — the Aferiy P280 runs longer: 24.9 hours against 18.8. 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 Aferiy P280 or VTOMAN FlashSpeed 1500?
- The VTOMAN FlashSpeed 1500, by 2.8 kg (18.8 kg versus 21.6 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 Aferiy P280 for home backup; the VTOMAN FlashSpeed 1500 for camping & rv. They split, so the honest answer depends on which of those you are actually buying for.
