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 AC180P costs $1600 less. Whether that gap is worth closing depends on what you need to run.
- Allpowers R4000 holds 140% more energy (3456Wh vs 1440Wh), 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 AC180P is 69.0 lb lighter (37 lb vs 106 lb).
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
Bluetti AC180P
A higher-capacity take on the AC180, adding 25% more watt-hours for the same 1,800W output — a useful step up if you catch it near the AC180's price.
Best for: Buyers who want more than 1kWh from a mainstream brand on sale.
Where it falls short:
- 37 lb
- 2,700W surge is mid-pack
- Not expandable
