Bluetti EB3A vs DJI Power 500

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

Bluetti EB3A costs $120 less. Whether that gap is worth closing depends on what you need to run.

DJI Power 500 holds 91% more energy (512Wh vs 268Wh), so it runs the same load proportionally longer.
DJI Power 500 has 800W more surge headroom (2000W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
Bluetti EB3A is 6.2 lb lighter (10.1 lb vs 16.3 lb).
DJI Power 500 is rated for 4,000 cycles vs 2,500 — 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.

Bluetti EB3A

The budget veteran. 268Wh at $239 with a 30-minute recharge — still one of the fastest-charging small units you can buy.

Best for: Budget campers who value fast top-ups between trips.

Where it falls short:

2500 cycles is the lowest here
268Wh empties fast under real load

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
