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 EB3A costs $2060 less. Whether that gap is worth closing depends on what you need to run.
- Allpowers R4000 holds 1190% more energy (3456Wh vs 268Wh), so it runs the same load proportionally longer.
- Allpowers R4000 has 4800W more surge headroom (6000W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti EB3A is 95.9 lb lighter (10.1 lb vs 106 lb).
- Allpowers R4000 is rated for 3,500 cycles vs 2,500 — meaningful if you cycle it daily.
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
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
