EcoFlow RIVER 2 Series Comparison: Features, Specs, Applications


The EcoFlow RIVER 2 series offers industry-leading portable power stations designed for off-grid electricity, entry-level emergency backup power for essential appliances, and compact power on the go. 

EcoFlow RIVER 2 is the next generation of EcoFlow’s game-changing RIVER series that redefines what compact off-grid power can mean…

It’s an upgrade in every way. 

Here’s an in-depth look at what each EcoFlow RIVER 2 model has to offer, depending on your specific use case. 

We’ll compare portability, battery capacity, AC output (starting and running watts), solar charging capacity, battery chemistry, and more.

6 Tips for Choosing a Portable Power Station (PPS)

EcoFlow RIVER 2 series portable power stations offer the best compact power solution for off-grid adventures. 

Like EcoFlow’s EcoFlow DELTA series, the EcoFlow RIVER 2 series comes in various shapes and sizes, with different features tailored toward different users and scenarios. 

Here are the essential factors to consider when purchasing an EcoFlow off-grid power solution that’s right for you.


The best portable power station is one that’s lightweight and compact enough to meet your off-grid electricity needs. Let’s face it – lugging around a massive battery is no one’s idea of fun. 

EcoFlow RIVER 2 series portable power stations start at 7.7 lbs (3.5 kg) and go up to 17.2 lbs (7.8 kg).  

If you’re looking for something feather-light and small enough to fit in your backpack, EcoFlow RIVER 2 is a great choice. 

If you need something compact to power more devices,  EcoFlow RIVER 2 Max offers a 512Wh capacity and weighs just 13.2 lbs (6.1 kg).  Maybe not ideal for long hikes, but certainly manageable.

Battery/Storage Capacity

The capacity of your PPS determines how long you can operate your personal devices and appliances between charges. Large-capacity portable power stations like EcoFlow DELTA 2 and EcoFlow DELTA Pro are better suited for heavier applications like emergency backup or residential off-grid power. 

If you need a compact option that can power 80% of home appliances but still weighs under 20 pounds, at 17.2 lbs (8 kg), EcoFlow RIVER 2 Pro offers 768 Wh battery storage — perfect for off-grid weekends away with the family.

AC Output

Along with storage capacity, the maximum AC output of a PPS or generator is crucial to understand. 

If you buy a PPS with insufficient starting and running watts to power your desired appliances — simultaneously — you will have to make compromises. A small PPS like EcoFlow RIVER 2 is great for hiking and keeping your laptop charged, but it won’t run a fridge.

If your main goal is keeping your personal devices charged and running a few small appliances, EcoFlow RIVER 2 or EcoFlow RIVER 2 Max could be the perfect fit.

However, if you want to run more demanding appliances, EcoFlow RIVER 2 Pro or an entry-level home backup power solution like EcoFlow DELTA 2 is likely better suited to your needs.

Thanks to EcoFlow’s proprietary X-Boost technology, EcoFlow RIVER 2 Pro still packs a powerful punch with 800W of running electricity and 1600W of surge power (starting watts). 

Fast Charging

You don’t want to wait half a day to charge up when you’re on the go. All EcoFlow portable power stations feature X-Stream — offering lightning-fast charging and intelligent battery management.

EcoFlow RIVER 2 charges from 0-100% in just 60 minutes using AC power. EcoFlow RIVER 2 Pro offers three times the storage capacity at 768Wh, but it only takes 10 minutes longer to charge using AC. 

Or, you can go solar. Depending on environmental conditions, such as available sunlight, EcoFlow RIVER 2 Pro can recharge 0-100% in 4.5-9 hours using a 22oW Bifacial Portable Solar Panel

The EcoFlow RIVER 2 series offers 5x faster charging than its PPS competitors.

Solar Charging Input

For off-grid camping, tailgating, or other outdoor activities, charging your EcoFlow RIVER 2 PPS with a solar panel gives you true energy independence. You can harness the sun’s power to generate clean, renewable energy

What if you’re not blessed with all-year-round Arizona sunshine? 

Not to worry. 

The EcoFlow RIVER 2 series portable power stations have an advanced MPPT solar charge controller that automatically monitors voltage and current in real-time to increase solar electricity generation, even in cold and cloudy conditions.

Battery Chemistry

You’ll often hear portable power stations called solar, battery, or even portable generators. Ultimately, they’re all battery-powered devices. 

One essential factor to consider is battery chemistry. 

The EcoFlow RIVER 2 series utilizes cutting-edge Lithium Iron Phosphate battery chemistry — also known as LFP or LiFeP04. LiFePO4 is a newer subset of the traditional Lithium-Ion (Li-Ion) battery chemistry commonly found in older PPS models and Electric Vehicles.

LiFePO4 offers many advantages over Li-Ion, including longer lifespans, faster recharge times, and increased performance in extreme temperatures.

LiFePO4 also doesn’t require cobalt, an essential material for other Li-Ion batteries. Cobalt is primarily mined unethically in the Democratic Republic of Congo (DRC) — often using child labor. Working conditions are so poor that cobalt is commonly referred to as a blood metal.

EcoFlow RIVER 2 Series: Head-to-Head Comparison

Now that you know the essential factors to consider when choosing a portable power station, let’s compare EcoFlow’s EcoFlow RIVER 2 series head-to-head.

EcoFlow RIVER 2 

EcoFlow RIVER 2 is the smallest portable power station in the EcoFlow RIVER 2 series. It’s more powerful than a power bank and more compact than other portable power stations. 

With a feather-light EcoFlow RIVER 2, you can take electricity to go — anywhere.

Portability: Best for Hiking and Backpacking

When we say the EcoFlow RIVER 2 is small and light, we’re not kidding.  

Weighing just 7.7 lbs (3.5 kg) with tiny dimensions of 9.6 x 8.5 x 5.7 inches (245 x 214 x 142 mm), you can carry EcoFlow RIVER 2 in one hand or put it in your backpack.  

If you’re looking for something more powerful than a power bank to charge your personal devices off-grid but don’t want to skimp on portability, EcoFlow RIVER 2 is a great option.

Capacity: 256Wh 

Even higher-capacity portable power banks only store about 20,000 mAh of electricity. That’s roughly 74Wh. At 256wH, EcoFlow RIVER 2 offers almost 250% more electricity storage capacity.

AC Output: 300W (600W Surge Power w/X-Boost)

You can’t run a washing machine with EcoFlow RIVER 2, but you’re not likely to take one camping anyways. 

With 300W operating AC output (600W starting wattage with X-Boost), you can run up to 99% of consumer electronics. 

Need to charge numerous devices at once? With multiple AC, USB-A, USB-C, and DC outlets, EcoFlow RIVER 2 has you covered.

Fast Charging with X-Stream: 0-100% in 1 hour

Charging doesn’t have to be a chore. The EcoFlow RIVER 2 mini charges from 0-100% in one hour using household AC electricity.
