EcoFlow RIVER 3 Plus vs Bluetti Apex 300
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 $1270 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti Apex 300 holds 866% more energy (2764Wh vs 286Wh), so it runs the same load proportionally longer.
- Bluetti Apex 300 has 6480W more surge headroom (7680W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 3 Plus is 69.5 lb lighter (9.9 lb vs 79.4 lb).
- Bluetti Apex 300 is rated for 6,000 cycles vs 3,000 — meaningful if you cycle it daily.
EcoFlow RIVER 3 Plus
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
Bluetti Apex 300
6000 cycles at 2764Wh — the best long-term cost-per-kWh in this list if you cycle daily. Bluetti's answer to the Elite 200 V2 at scale.
Best for: Off-grid solar setups where daily cycling makes lifespan the dominant cost.
Where it falls short:
- 79.4 lb
- Newer product with limited long-term field data
