Bluetti AC180P vs Allpowers R1500
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
These two cost the same, so the decision comes down to what you're powering.
- Bluetti AC180P holds 25% more energy (1440Wh vs 1152Wh), so it runs the same load proportionally longer.
- Allpowers R1500 has 300W more surge headroom (3000W vs 2700W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti AC180P is 0.5 lb lighter (37 lb vs 37.5 lb).
Neither of these will start a sump pump or well pump — both surge below the ~3,400W those motors need. If home backup with pumps is your use case, look at higher-surge models instead of either of these.
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
A well-priced 1.1kWh with a real 1,800W output and fast charging, a common budget pick for home backup starter kits.
Best for: First-time backup buyers who want 1,800W output cheap.
Where it falls short:
- 37.5 lb for 1.1kWh
- Not expandable
