The short answer
Bluetti Apex 300 costs $700 less. Whether that gap is worth closing depends on what you need to run.
- Allpowers R4000 holds 25% more energy (3456Wh vs 2764Wh), so it runs the same load proportionally longer.
- Bluetti Apex 300 has 1680W more surge headroom (7680W vs 6000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti Apex 300 is 26.6 lb lighter (79.4 lb vs 106 lb).
- Bluetti Apex 300 is rated for 6,000 cycles vs 3,500 — meaningful if you cycle it daily.
