Quick answers

Is the Aferiy P280 better than the VTOMAN FlashSpeed 1500?
Aferiy P280 leads by 24 points overall.
Which has more usable capacity, the Aferiy P280 or VTOMAN FlashSpeed 1500?
The Aferiy P280, by 425 Wh — 1,741 Wh versus 1,316 Wh, a 32% advantage. At a 60 W load that is roughly 7.1 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: 27.6 hours against 20.9. 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 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.
