EcoFlow RIVER 3 Plus 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
EcoFlow RIVER 3 Plus costs $370 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti AC180P holds 403% more energy (1440Wh vs 286Wh), so it runs the same load proportionally longer.
- Bluetti AC180P has 1500W more surge headroom (2700W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 3 Plus is 27.1 lb lighter (9.9 lb vs 37 lb).
- Bluetti AC180P is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
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.
Doubles the River 3's output for $90 more, and adds an expansion battery port. The better buy of the two unless weight is everything.
Best for: Campers who want one unit that covers devices plus the occasional small appliance.
Where it falls short:
- 286Wh alone is a single evening of real use
- 220W solar input is modest
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
