The EcoFlow RIVER 3 Plus portable electric supply extends your main station's runtime. Compact and light, it gives more power for weekends in rooftop tents or extended trips in campervans across Canada.

It connects instantly to the EcoFlow RIVER 3 Plus power bank with AC outlet thanks to its wireless Pogo Pin link, offering a simple and quick plug-and-play system.

Technical Features of the Portable Electric Supply

  • Capacity: 286 Wh (EB300) or 572 Wh (EB600) — total reach up to 858 Wh.
  • USB-C Port: 140 W — bidirectional input/output for flexible charging.
  • Connection: Wireless via Pogo Pin — setup without bulky cables.
  • Independent Use: Works alone for light or minimalist setups.
  • Battery: LiFePO₄ — 3000 cycles, about 10 years of lifespan.
  • Weight: Ultra-light for easy carry in vehicles or backpacks.
