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.

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.

Style: RIVER 3 Power Station
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!
