Choose EcoFlow for faster backup switchover, longer cycle ratings, lighter stations and expansion at 1 kWh; choose Bluetti for a bit more battery at 1 kWh and more output at 2 kWh. Both brands offer 5-year warranties on the models we've reviewed.
The short answer: EcoFlow vs Bluetti
Faster backup vs more output at 2 kWh
- Choose EcoFlow for a 1 kWh station that switches over fast enough for computers, takes lots of solar and can grow to 5 kWh.
- Choose Bluetti for a slightly bigger 1 kWh battery (AC180), or a 2 kWh station with 2,600 W of output (Elite 200 V2).

Lineups compared
Where each brand has models
From EcoFlow we've reviewed the 286 Wh River 3 Plus, the 1 kWh Delta 3 and Delta 3 Plus, the 3.6 kWh DELTA Pro, which is 120 V from a single unit, and the 4 kWh DELTA Pro 3 with 120/240 V.
From Bluetti we've reviewed the 268 Wh EB3A and 288 Wh Elite 30 V2, the 1,152 Wh AC180, the 2,074 Wh Elite 200 V2 and the 2,765 Wh, 120/240 V Apex 300. Some Bluetti pages list the AC180 as phased out, so check availability of the exact model.
Charging and solar
Close at 1 kWh, with EcoFlow ahead on solar
The Delta 3 Plus refills from the wall in about 56 minutes. The AC180 reaches 80% in about 45 minutes; Bluetti doesn't state a full-charge time.
On solar, the Delta 3 Plus takes 1,000 W and the Delta 3 500 W; the AC180 takes 500 W. At 2 kWh, the Elite 200 V2 takes 1,000 W. See what size solar panel you need.
Backup (UPS) and expansion
EcoFlow is faster and grows further
EcoFlow's Delta 3 series switches over in about 10 ms, fast enough for most computers. Bluetti's are slower: ≤15 ms on the Elite 200 V2 and 20 ms on the AC180, fine for routers and fridges but less certain for desktop PCs.
The Delta 3 series expands to 5 kWh with EcoFlow extra batteries. The AC180 can add a B80 battery in power-bank mode, for about 1,958 Wh in total, and the Elite 200 V2 doesn't expand.
Battery life and warranty
Same warranty, longer EcoFlow cycle ratings
Both brands give 5-year warranties on these models. EcoFlow rates its batteries for 4,000 cycles to 80%; Bluetti rates the AC180 for 3,500+ cycles and the Elite 200 V2 for 3,000+ cycles to 80%. All use LiFePO4.
