Bluetti AC500 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
Allpowers R1500 costs $1300 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti AC500 holds 167% more energy (3072Wh vs 1152Wh), so it runs the same load proportionally longer.
- Bluetti AC500 has 7000W more surge headroom (10000W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Allpowers R1500 is 28.6 lb lighter (37.5 lb vs 66.1 lb).
Bluetti AC500
A modular home-backup system, not a portable unit — the AC500 has no internal battery at all until you add B300K packs.
Best for: Serious home-backup builds where you're designing a system, not buying an appliance.
Where it falls short:
- Requires separate battery packs to function at all — budget accordingly
- Total system cost climbs fast
Allpowers R1500
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
