The Sweet Spot of Power & Portability.

The EcoFlow RIVER 3 Max is designed for those who need more juice than the standard model but want to keep their gear lightweight. With a 572Wh capacity, it doubles the runtime of the entry-level version, making it the ideal companion for weekend camping trips, overlanding, or keeping vital devices running during a power outage.

Despite its increased capacity, it remains compact enough to carry with one hand, fitting easily into your car boot or campsite setup without taking up valuable space.

Key Features:

• 🔋 Versatile 572Wh Capacity: Double the power of the standard RIVER 3 Plus. This capacity is perfect for extended day trips or weekend getaways, allowing you to run portable fridges, lights, and laptops for significantly longer.

• ⚡ Rapid 1.3-Hour Recharging: Get back on the road faster. With EcoFlow’s industry-leading X-Stream fast charging, you can top up from 0% to 100% in just 1.3 hours via a standard wall outlet.

• 🚀 600W Output (Surge 1200W): Don't compromise on what you can plug in. With X-Boost technology, the RIVER 3 Max can power devices up to 1200W, handling electronics like blenders, coffee makers, and power tools.

  
  

• 🤫 Ultra-Quiet Operation: Rated at <30dB, this power station is quieter than a whisper. It’s unobtrusive enough to use inside a tent or right next to your bed to power a CPAP machine.

• 🛡️ Built to Last (LiFePO4): Powered by safe and durable LFP battery chemistry, the RIVER 3 Max is built for 3,000+ cycles (approx. 10 years of daily use) while maintaining 80% battery health.
