The differences that matter
- Noise level: 30 dB vs 45 dB (manufacturer-rated) → the RIVER 3 is quieter when running.
- Warranty: 2 years vs 3 years.
- Backup power: the RIVER 3 runs full continuity (UPS), the Explorer 300 Plus has a brief pause (EPS) before it kicks in.
Which one to choose
Choose EcoFlow RIVER 3 if…
The RIVER 3 is quieter, manufacturer-rated at 30 dB against the Explorer 300 Plus's 45 dB, and it's the right choice for keeping it running close by, at night for example. The trade-off is a shorter warranty, 2 years against 3.
Choose Jackery Explorer 300 Plus if…
The Explorer 300 Plus offers a longer warranty, 3 years, and backup power with full continuity instead of the RIVER 3's brief pause. In exchange it's a noisier unit when its fan is running.
