Bluetti AC180 vs Allpowers R4000
Side-by-side on the specs that decide it — surge, capacity, runtime and price.
Both models' specs verified against manufacturer listings · Last updated
The short answer
Bluetti AC180 costs $1500 less. Whether that gap is worth closing depends on what you need to run.
- Allpowers R4000 holds 200% more energy (3456Wh vs 1152Wh), so it runs the same load proportionally longer.
- Allpowers R4000 has 3300W more surge headroom (6000W vs 2700W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti AC180 is 68.6 lb lighter (37.4 lb vs 106 lb).
Bluetti AC180
A solid mid-size unit that competes on price rather than any standout spec. 1152Wh is a useful step above the 1kWh crowd.
Best for: Buyers who catch it on sale and want slightly more than 1kWh.
Where it falls short:
- 37.4 lb is heavy for its capacity
- 2700W surge is mid-pack
- Not expandable
Allpowers R4000
A large expandable unit that undercuts the EcoFlow Delta Pro 3 on price while matching its 4,000W output — the trade is a less established support network.
Best for: Whole-home backup buyers prioritising price per watt over brand.
Where it falls short:
- 106 lb
- Brand support and resale trail the big names
