I recently purchased the EcoFlow River 3 and it came paired with the 45W solar panel, and I have to say, it’s been a fantastic investment. It works great both as a UPS (uninterruptible power supply) and for camping, providing reliable power when and where I need it most.
The EcoFlow River 3 has become my go-to UPS for essential devices like my router, laptop, and even a few small appliances. During power outages, it seamlessly switches over to battery power with its <10 ms response time, ensuring that my devices stay powered without any interruptions. I’ve had it power my router and computer for several hours during brief outages, allowing me to keep working and stay connected. The switch from grid power to the River 3 is practically instantaneous, so there’s no downtime, which is critical for anyone working from home or relying on continuous internet access.
As a camping companion, the EcoFlow River 3 has been incredibly convenient. It’s compact, lightweight, and powerful enough to run small appliances like a portable fridge, lights, and charge multiple devices at once. Whether I’m using it to power a fan on hot nights or keep my camera and phone charged, it’s a great companion for outdoor adventures. The 45W solar panel that comes with the River 3 is a nice addition, offering a reliable way to recharge the power station during the day when you’re off the grid. It’s lightweight and portable, so it doesn’t take up much room in my pack, and it’s easy to set up. Even on partly cloudy days, it provides enough power to keep the River 3 topped off for daily use.
I’ve been impressed with the fast charging of the EcoFlow River 3—it goes from 0% to 100% in just about an hour when plugged into a wall outlet, which is fantastic for a portable power station. When using the solar panel, it charges at a decent rate, allowing me to keep everything powered without worrying about running out of juice. Even with the 45W panel, I’ve found it efficient enough for camping trips, especially when I need to recharge between activities or overnight.
Quiet Operation
Another huge advantage is how quiet the EcoFlow River 3 operates. Whether I’m using it at home as a UPS or at the campsite, it runs silently in the background, unlike gas-powered generators. This makes it perfect for use in more tranquil settings, whether you’re indoors or out in nature.
Overall, I’m extremely happy with the EcoFlow River 3 and 45W solar panel combination. The panel gets about 35w on my porch but I also connected two 45w panels together to get about 75w consistently. As a UPS, it keeps my critical devices powered during outages without a hitch. For camping, it’s reliable and versatile enough to meet all my power needs while being compact and easy to carry. If you’re looking for a portable power station that’s both reliable for home backup and efficient for outdoor adventures, the EcoFlow River 3 is an excellent choice. It’s a great value for the performance it delivers, and the solar panel is the perfect addition for sustainable, off-grid power. Highly recommended!

Packs a punch, powerful device, slick design
EcoFlow continually refreshes their product lineup, and I have to say, this third generation is looking extra slick. Coming from both the original River Bank, River 1, and River 2 series, this River 3 has inherited much of the same DNA but evolved.First things first, this thing is light...about 7.7 lbs. The greatest design refresh is that the carry handle no longer protrudes past the box profile like it did on the River 2 Pro. That makes it so much easier to fit into standard spaces.The unit itself is 245 wh, which is enough to power a laptop for a long work session, even with multiple external monitors attached. I tested it during a mountain getaway, and it performed flawlessy.The fans are quiet, and the unit includes 2 AC plugs (one grounded), 2 USB-A ports, 1 USB-C PD (100w) port, and a 12v cigarette lighter port. Unfortunately, there's no wireless charging or expansion battery slots or even an LED anymore. But that's not the intended goal of such a small unit. This one aims for portability and straightforward use.The buttons and power ports are all on the front face, which includes an easy-to-read LCD readout with important info like watts and hours left. It's rated for 300w (600w with the X-boost feature), which I tested to its max. It actually pushed past a few watts for several minutes without any noticeable hang-up.You won't be powering any space heaters or hair dryers with this, but for small appliances, the River 3 is ideal. Solar input is decent too, and I like the improved features in the accompanying EcoFlow app, which enables things like slow or fast charging, charging/discharge limits, and much more. The device can now even function as a true UPS with under 20 ms switchover.This is now my go-to unit for cafe work on my laptop. While the River 2 Pro is more powerful, it was simply too big and heavy. The River 3 gets me through a long work session without problem, and the lightweight and compactness make it far more practical. I do wish it allowed for expansion batteries, but that seems to be reserved for the higher models in the River 3 lineup. Would have been nice to have a couple more USB-C ports and at 140w, but not a big issue. Overall, the River 3 rocks.

- Reviewed in the United States on September 17, 2024Style: RIVER 3 Power StationVerified Purchase
I've owned the EcoFlow Delta series, and while the River 3 doesn't directly compare to the Delta models, it's clear they are designed for different purposes. The River 3 features a 245Wh LifePO4 battery and delivers 300W of continuous power with a 600W boost mode for peak needs. That's plenty to run electronic devices and small appliances. What really impressed me is how portable and lightweight it is—its compact size is a pleasant surprise.
Tiny entry-level portable batteries yet powerful
Reviewed in the United States on September 17, 2024
I connected it to my 100W rigid solar panel, which provided about 75W (due to weather conditions), and within 3 hours, it charged from 30% to full. Its portability is a huge advantage, making it easy to transport and convenient to use in any setting. The battery comes equipped with two AC outputs, two USB-A ports, one USB-C port, and a DC carport, covering most of your charging needs.
One standout feature is the incredibly fast AC switching time—the inverter kicks in under 1 second, which is faster than my Delta 2 (which takes about 3-5 seconds). For such a small battery, it packs a punch, and with solar power, I can rely on renewable energy year-round.
One minor downside is the 110W solar input limit. Given the 245Wh capacity, a higher input—like 200W—would be great, but I understand that the River series is more about everyday convenience than the heavy-duty performance of the Delta line. Overall, the River 3 is a fantastic portable power solution for daily life.
