The EcoFlow RIVER 2 Max 500 Is Your Go-To Easy-To-Carry Reliable Power Source Wherever Your Life Takes You
Power outages, remote campsites, and open-road adventures all have one thing in common: they demand a power source you can genuinely trust. The EcoFlow RIVER 2 Max 500 Portable Power Station delivers exactly that: a compact, 499Wh powerhouse that recharges from flat to full in just 60 minutes, keeps your critical devices and appliances running through virtually any scenario, and does it all with a battery chemistry engineered to last a decade.
Whether you're an RVer who refuses to sacrifice comfort on the road ore an off-grid enthusiast living life on your own terms, the RIVER 2 Max 500 was built with you in mind.
At just 13.2 lbs, and compact enough to stow under a van seat or tuck into a gear closet, this power station punches well above its weight class. It's not just a battery backup; it's a complete, portable energy system that brings juice with you everywhere you go.
EcoFlow RIVER 2 Max 500 Features
It Charges From Zero to Full in Just 60 Minutes
Most power stations take 5–8 hours to fully charge. This one refills completely in just one hour using a wall outlet. That means less waiting and more doing whether you're prepping for a storm or heading out on the road.
The Battery Lasts Up to 10 Years Without Losing Power
Built with LFP (Lithium Iron Phosphate) cells, this battery holds 80% of its original capacity even after 3,000 charge cycles. That's roughly a decade of daily use far longer than most backup batteries on the market today.
It Runs Appliances That Use Twice Its Rated Power
X-Boost technology lets this 500W station power devices up to 1,000W like coffee makers, hair dryers, and small power tools. You get more usability without needing a bigger, heavier, more expensive unit.
The Sun Can Recharge It With Up to 1.5kWh Every Day
Connect compatible solar panels and this station can generate up to 1.5 kilowatt-hours of free energy daily. That's enough to keep your fridge, lights, phone, and laptop running all day without touching a wall outlet.
It Has Been Independently Certified as Safe by TÜV Rheinland
This is the first portable power station to earn TÜV Rheinland safety certification a respected third-party stamp of approval. You're not just trusting the brand's word; an independent global testing body has verified it is safe.
Four Different Ways to Charge It Means You're Never Stuck
Recharge via wall outlet, car port, solar panels, or USB-C whichever fits your situation. At home, on the road, or deep in the backcountry, you always have a practical way to refill your power supply.
At Just 13.2 Pounds, It Goes Wherever You Need Power
This station weighs less than a small bag of dog food and fits in tight spaces like van cabinets, RV compartments, or truck beds. Lightweight and compact, it travels as easily as the gear you're using it to power.

This works very well. I can charge my unit and expansion batteries more than twice as fast as using a 120 volt wall outlet. I think it also helps with the battery temperature.
