Quick answers

Is the Anker SOLIX C300 better than the FlashFish A301?
Anker SOLIX C300 leads by 19 points overall.
Which has more usable capacity, the Anker SOLIX C300 or FlashFish A301?
The Anker SOLIX C300, by 46 Wh — 269 Wh versus 223 Wh, a 21% advantage. At a 60 W load that is roughly 0.8 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 Anker SOLIX C300 or FlashFish A301?
The FlashFish A301: 300 W versus 320 W continuous. That gap matters only if a load sits between the two numbers — below 300 W both run it, above 320 W neither does. Surge headroom follows the same order: 600 W against 600 W, and surge is what decides whether a compressor or pump actually starts.
How does runtime compare between the Anker SOLIX C300 and FlashFish A301?
On the same sourced load — a refrigerator (full-size) — the Anker SOLIX C300 runs longer: 4.3 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 Anker SOLIX C300 or FlashFish A301?
The FlashFish A301, by 0.9 kg (3.2 kg versus 4.1 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 FlashFish A301 for home backup, camping & rv. One model leads every use case we score here, which makes this an unusually clean choice.
