Quick answers

Is the Anker SOLIX F3800 better than the Bluetti Apex 300?
Bluetti Apex 300 leads by 8 points overall.
Which has more usable capacity, the Anker SOLIX F3800 or Bluetti Apex 300?
The Anker SOLIX F3800, by 699 Wh — 3,264 Wh versus 2,565 Wh, a 27% advantage. At a 60 W load that is roughly 11.7 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 F3800 or Bluetti Apex 300?
The Anker SOLIX F3800: 6,000 W versus 3,840 W continuous. That gap matters only if a load sits between the two numbers — below 3,840 W both run it, above 6,000 W neither does. Surge headroom follows the same order: 9,000 W against 7,680 W, and surge is what decides whether a compressor or pump actually starts.
How does runtime compare between the Anker SOLIX F3800 and Bluetti Apex 300?
On the same sourced load — a refrigerator (full-size) — the Anker SOLIX F3800 runs longer: 51.8 hours against 40.7. 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 F3800 or Bluetti Apex 300?
The Bluetti Apex 300, by 22 kg (38 kg versus 60 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 Anker SOLIX F3800 for home backup; the Bluetti Apex 300 for camping & rv. They split, so the honest answer depends on which of those you are actually buying for.
