DJI Power 500 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 July 29, 2026

The short answer

DJI Power 500 costs $340 less. Whether that gap is worth closing depends on what you need to run.

Allpowers R1500 holds 125% more energy (1152Wh vs 512Wh), so it runs the same load proportionally longer.
Allpowers R1500 has 1000W more surge headroom (3000W vs 2000W) — that decides whether a fridge, pump or AC compressor will actually start.
DJI Power 500 is 21.2 lb lighter (16.3 lb vs 37.5 lb).
DJI Power 500 is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.

⚠️ Before you buy

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.

DJI Power 500

The smaller DJI unit: 512Wh and 1,000W make it a capable weekend companion, with fast charging and low noise as the standouts.

Best for: Weekend campers and creators who want a light, fast-charging half-kWh unit.

Where it falls short:

512Wh is a single-day capacity
No expansion

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
