EcoFlow DELTA Pro vs Bluetti AC180P

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 AC180P costs $2500 less. Whether that gap is worth closing depends on what you need to run.

⚠️ Before you buy

The EcoFlow DELTA Pro is poor value on paper: 1.13 Wh per dollar versus 2.06 for the Bluetti AC180P. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.

EcoFlow DELTA Pro

The previous-generation flagship, now mostly worth buying on discount. The Pro 3 beats it on nearly every axis.

Best for: Bargain hunters who find it steeply discounted against the Pro 3.

Where it falls short:

  • 99 lb and 165-minute recharge — both beaten by the Pro 3
  • Aging platform; expect it to be phased out
Bluetti AC180P

A higher-capacity take on the AC180, adding 25% more watt-hours for the same 1,800W output — a useful step up if you catch it near the AC180's price.

Best for: Buyers who want more than 1kWh from a mainstream brand on sale.

Where it falls short:

  • 37 lb
  • 2,700W surge is mid-pack
  • Not expandable
