EcoFlow River 2 Series Comparison: Features, Specs, Applications.

The EcoFlow River 2 series offers industry-leading portable power stations designed for emergency, off-grid, and portable power on the go. This portable power station comparison takes a look at each EcoFlow River 2 product, comparing portability, capacity, output, solar capability, battery chemistry, and more.

6 Tips for Choosing a Portable Power Station

EcoFlow River 2 series portable power stations offer the best portable power for off-grid adventures. Just like the EcoFlow DELTA 2 series, the River 2 series come in various shapes and sizes, with different features tailored toward different users. Take a quick look below at everything you need to know before buying a River 2 series portable power station.


The best portable power station is the one that you can take around and use anywhere. Because, let’s face it – lugging around a huge battery is not fun. EcoFlow River 2 series portable power stations start at 3.5 kg and go up to around 6.1 kg. So if you’re looking for something super light and small, the new EcoFlow River 2 is a great choice. Or, if you’re looking for something light with a larger capacity, the EcoFlow River 2 Max has a detachable battery that you can take off whenever you like.


The capacity of your portable power station determines how long you can stay powered on, with larger capacities suited towards heavier applications like emergency or off-grid power. The RIVER 2 series features smaller capacities to power smaller electronics and devices without adding much bulk or weight.


This one is pretty simple — higher outputs allow you to power more demanding appliances like hairdryers, small fridges, or even vacuums (camping can get messy). The good news is that all EcoFlow portable power stations feature X-Boost technology, extending your output whenever you need extra power.

Fast Charging

Nobody wants to wait half a day to charge up. All EcoFlow portable power stations feature extremely fastest charging in as little as 60 minutes.

Solar Charging

Whether you’re camping or out in the wild, solar charging gives you another effortless charging option to stay powered on. For those of you in sunny locations, you can harness the sun’s power to generate reliable solar energy. What if you’re not blessed with all-year-round sunshine? Not to worry. EcoFlow portable power stations have an advanced MPPT algorithm that automatically detects voltage and current in real-time to increase solar generation, even in cold and cloudy conditions.

Battery Chemistry

You’ll often hear a portable power station called a solar generator, battery generator, or even a portable generator. At the end of the day, they’re all portable battery-powered devices. One important thing to look out for is the battery chemistry. The EcoFlow River 2 series utilizes LFP batteries, which reduce the unit’s weight and increase the output performance in colder environments. That gives you a lightweight battery you can use all year round.

Now that we have all that covered, let’s start by looking at the EcoFlow River2  series.
