Awesome new power station
Style: RIVER 3 Power Station
I am a user of multiple products from EcoFlow, including one of the original River series power stations. I looked forward to this newest version, the River 3 once they announced it was coming. I was not disappointed. This is a small form factor power station that is good for travel and when you don't have a lot of room but you need something to charge up some of your portable devices or power some small appliances. This weighs in about 10lbs so it is easily moved by most people. Out of the box, I was impressed with the feel of this device. It just seems really well put together. I plugged it into an AC outlet to charge it up and just as advertised, it charged up very quickly. One of the things that I like very much is the accompanying EcoFlow application. When I opened the app, it immediately recognized the new device via bluetooth. Setup on my network was quick and easy and required no real effort on my part. As I looked through the app, one feature that was new to any EcoFlow device that I have seen was a section that showed the current Wifi connectivity. It allows you to verify the connection, see the signal strength, IP address, and even the MAC address. Very handy indeed! It will let you change to a different network, if needed and is just an excellent feature. It is so handy that I even emailed EcoFlow and told them they need to add this to ALL their device applications. I used the River 3 to charge my cell phone and also to power up my laptop, both use USB C connectivity. This is a 300 Watt device with an X-boost up to 600 Watts, so it will handle most small appliances. It is super quiet also. Even when it was charging, I had it in my bedroom while I was sleeping and didn't even hear it. If you need something as a UPS support for a network device or some other small appliance, this device will handle that job. It has 20 MS UPS support, which I tested. It worked flawlessly. I have a network based over the air tuner/DVR that is very sensitive to power outages. It kept going when I unplugged the AC without a hiccup. Very, very pleased with this device and so happy that I made this purchase!

Portable, powerful, quiet and used on a daily basis
Style: RIVER 3 Power Station
Love It! I've had this for several months and it has been used a UPS more than anything else. It's quiet, has decent battery life, and can keep my wifi router/modem powered for days. So far it has served admirably to keep the modem running during those periods when the weather causes the lights to blink off and on repeatedly. By keeping the modem/router connected as well as my cpu & monitor, I can keep on working without interruption or loss of data. It recharges quickly and is very quiet (unlike a couple of other units I have). Recharges quickly from either direct AC or a 100 watt solar panel. It won't power my fridge, but will keep my computer station up and running for several hours with the power off. I've used this unit since it's so light an portable to take on trips to the store to power my 12 volt fridge for frozen items purchased. Now I no longer have to rush home to put purchases in the freezer because of the 100 degree temps here in Texas. The 100 watt usb connection has been handy for charging a laptop while using it. The app allows a level of control that enhances the usefulness of the power station as well. Great entry level power station. This makes a great UPS that can keep you powered for less . Mine is plugged in and working as such 24/7 with no complaints. It was my first power station purchase and has resulted in my purchase of 3 other units to fit niches in my preparedness plans. Catch this on sale and you won't regret it.

Excellent UPS Alternative for Networking and Computer Equipment
Style: RIVER 3 Power Station
Background & Use Case I purchased this power bank as an emergency replacement when my dedicated UPS failed, specifically to protect my computer networking and home server equipment. After extensive testing, I'm impressed enough to consider this as my go-to solution for future UPS failures. Performance & Reliability Seamless Power Transition: The switchover from AC to battery power is impressively fast. When I unplugged the unit from the wall outlet during testing, my networking hardware didn't even register a blip - no reboots, no connection drops, nothing. The transition appears instantaneous. Real-Time Monitoring: One significant advantage over traditional UPS units is the built-in display that shows actual power draw from connected devices. This makes it easy to monitor your equipment's power consumption and estimate runtime. Charging Speed: The unit charges rapidly, which means less downtime when preparing for potential outages. Quiet Operation: Unlike many UPS units with cooling fans, this power bank runs silently - a major plus for home office environments. Key Considerations Surge Protection: The main trade-off compared to dedicated UPS systems is the lack of built-in surge protection. However, this is easily addressed (and potentially improved) by using a quality surge protector power strip in conjunction with the power bank. This combination may actually provide better surge protection than many budget UPS units. Power Capacity: This power bank delivers more usable power than the UPS it replaced, while the cost difference compared to replacing SLA batteries in the old UPS was minimal. Bottom Line For networking equipment and home servers, this power bank performs as well as or better than traditional UPS solutions at a competitive price point. The combination of seamless switching, real-time power monitoring, silent operation, and superior power capacity makes it an excellent alternative to conventional UPS systems. Recommendation: Highly recommended for anyone needing backup power for networking equipment, especially when paired with a quality surge protector. I'm already planning to replace my other aging UPS units with similar power banks.

It does what it says
Style: RIVER 3 Power Station
My use case is as a UPS that won't require a new lead acid battery every few years, and to increase power outage run time. It is hooked to my TV and the stereo for better sound. I am returning it because as I found out via testing, LG's "average power draw" and the actual power draw are not the same. This poor thing was asked to supply more than it was rated for. Draw under that amount worked great and I liked that it's input could keep up with the demand (I tried an Anker that was a mere 65 watts input). It was quieter than a Bluetti of the same rating, however I suspect the Bluetti's fans were coming on because of the high draw. Points to Bluetti for continuing to work, but I suspect it is safer for the equipment to refuse to allow a higher-than-rated draw so I'm glad this shut down and forced me to check the current. Their app is fine but it was annoying to find an old phone, set up a new Google account, and set up a guest network on my WiFi so I could run a PRC-based app. The size is OK, I personally wish it was taller rather than squat, more like a traditional UPS. I also wish the power IO was on an end, again like a traditional UPS. I don't see the advantage of the new model over the old one, but I've had to get the next size up portable power station for my TV. Before I knew the problem, I contacted their support and they got back to me in a reasonable amount of time. Their 2nd tier hasn't gotten back to me but first tier followed up, so points to them for support. Bottom line, if this met my needs, I'd keep it.

Love the size and power Love the size and power
Style: RIVER 3 Power Station
I’m loving my new River 3 by Ecoflow. It makes setting up outdoor movie nights for my family a breeze not having to run extension cords across the yard. This thing packs a punch! With a 300W AC output (surge up to 600W), it handled all my small to medium-sized devices with ease. I could charge my laptop, phone, and run a small mini fridge simultaneously without any hiccups. Because it's nice and compact and light I can grab and go throwing it in the minivan and the kids can keep the electronic devices running for hours on road trips. It supports fast charging, and I was able to charge it from 0% to 80% in just under an hour. For solar enthusiasts, it also comes with a solar charging port, up to 110w, and during a sunny day, I was able to fully charge it in under 3 hours using a solar panel. Pros: - Lightweight portable design. - Fast charging speed with multiple charging options (AC, DC, solar). - X-Boost feature allows for powering higher-wattage devices. - Long battery life with a high cycle count. - Easy-to-use interface with a reliable mobile app. Cons: - It's not the cheapest option out there, but given the features it offers and the fact that it’s from a leader in portable power solutions, I think it offers great value. -It doesn’t have a wireless charging pad for phone charging

Be Cautious of the "Warranty"
Style: RIVER 3 Power Station
I purchased the River 3 about a year ago. Everything was fine for the first few months and then it died and would not boot up. While this is dissapointing, these things happen, and this alone is not why I'm providing a one star rating. I'm providing a one star review to Ecoflow and their "warranty" process. While the warranty has not expired, the process has been a process full of numerous emails and phone calls. Ecoflow's final resolution was to offer me a used unit but will not give it to me until I send back my original unit and they are able to inspect it. The mistrust is palpable and the overall process has made us feel like second class citizens. A warranty is only as good as the company behind it and I am offering this simple review of my experience as a courtesy to the next person. I'm not upset or angry, I just think everyone should know that this "warranty" that Ecoflow likes to advertise it a bit of a process and filled with Ecoflow's mistrust and skepticism for its customers -all for a $170 solar battery system. Ecoflow - do better.

Good Power Station, But Not Suitable as UPS for OLED TVs
Style: RIVER 3 Power Station
I purchased the EF ECOFLOW Portable Charging Generator primarily to use as a UPS for a Sony OLED TV, but unfortunately, I wouldn’t recommend it for that specific use case. While the unit is compact, charges quickly, and offers a solid range of output ports with EcoFlow’s usual smart features, it has a key limitation: the continuous power output is capped at 300W. OLED TVs, like my Sony model, can occasionally spike above that during certain scenes, especially with HDR content or bright highlights which causes the battery to shut down unexpectedly. I had hoped the X-Boost feature would help mitigate this, but X-Boost only works when the unit is not being charged by the grid. Since a UPS setup involves constant charging, that option isn’t available in this context. That said, I have had success using this same EcoFlow unit as a UPS for a Samsung Frame TV, which is LED-based and does not suffer from the same high-wattage spikes. It’s been working flawlessly in that configuration with no shutdowns or interruptions, making it a viable UPS solution for non-OLED TVs or other electronics with consistent power draws. Addendum: I’ve since switched to using the EF ECOFLOW River 3 Plus as a UPS for my Sony OLED TV, and that setup has been working perfectly. The River 3 Plus offers a 600W continuous output, which comfortably handles the occasional power spikes from the OLED panel. So if you’re looking to back up an OLED TV with an EcoFlow system, I highly recommend stepping up to the River 3 Plus for peace of mind and reliable performance.
