Bluetti AC200Max vs Allpowers R4000
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 AC200Max costs $600 less. Whether that gap is worth closing depends on what you need to run.
- Allpowers R4000 holds 69% more energy (3456Wh vs 2048Wh), so it runs the same load proportionally longer.
- Allpowers R4000 has 1200W more surge headroom (6000W vs 4800W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti AC200Max is 44.1 lb lighter (61.9 lb vs 106 lb).
Bluetti AC200Max
The older AC200 workhorse. Still expandable and high-surge, but heavier and slower to charge than Bluetti's newer Elite and Apex units at similar prices.
Best for: Buyers who catch it discounted below the newer Elite line.
Where it falls short:
- 61.9 lb and a 150-minute recharge
- Outclassed by newer LiFePO4 units on charge speed
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
