Quick answers

Is the EcoFlow RIVER 3 Plus better than the FlashFish A301?
EcoFlow RIVER 3 Plus leads by 22 points overall.
Which has more usable capacity, the EcoFlow RIVER 3 Plus or FlashFish A301?
The EcoFlow RIVER 3 Plus, by 20 Wh — 243 Wh versus 223 Wh, a 9% advantage. At a 60 W load that is roughly 0.3 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 EcoFlow RIVER 3 Plus or FlashFish A301?
The EcoFlow RIVER 3 Plus: 600 W versus 320 W continuous. That gap matters only if a load sits between the two numbers — below 320 W both run it, above 600 W neither does. Surge headroom follows the same order: 1,200 W against 600 W, and surge is what decides whether a compressor or pump actually starts.
How does runtime compare between the EcoFlow RIVER 3 Plus and FlashFish A301?
On the same sourced load — a refrigerator (full-size) — the EcoFlow RIVER 3 Plus runs longer: 3.9 hours against 3.5. 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 EcoFlow RIVER 3 Plus or FlashFish A301?
The FlashFish A301, by 1.5 kg (3.2 kg versus 4.7 kg). Both weights are manufacturer figures for the bare unit; cables and a solar panel add to whatever you actually carry.
Which recharges faster from the wall, the EcoFlow RIVER 3 Plus or FlashFish A301?
The EcoFlow RIVER 3 Plus: 60 minutes from empty to full against 210 minutes, a difference of 150 minutes. This matters most between outages and during a short grid window — if you only ever recharge overnight, it does not matter at all.
Which model should I buy for my use case?
On the sub-scores that describe each use case: the EcoFlow RIVER 3 Plus for home backup; the FlashFish A301 for camping & rv. They split, so the honest answer depends on which of those you are actually buying for.
