Bluetti AC2A 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

Bluetti AC2A costs $500 less. Whether that gap is worth closing depends on what you need to run.

⚠️ 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 AC2A

One of the cheapest LiFePO4 stations on the market. 204Wh is tiny, but a 200W solar input that outpaces the capacity makes it a surprisingly capable little off-grid trickle unit.

Best for: Ultralight campers who recharge from a panel daily.

Where it falls short:

  • 204Wh is genuinely small
  • 300W output is device-only
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
