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 costs $1360 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti Apex 300 holds 1028% more energy (2764Wh vs 245Wh), so it runs the same load proportionally longer.
- Bluetti Apex 300 has 7080W more surge headroom (7680W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 3 is 71.6 lb lighter (7.8 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
A glorified power bank with AC outlets — and that's fine if that's what you need. 245Wh runs devices, not appliances.
Best for: Weekend campers charging phones, cameras and a laptop.
Where it falls short:
- 300W output rules out anything with a heating element
- No expansion path
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
