Portable Power Station River 2 Max 500, 499Wh LiFePO4 Battery/ 1 Hour Fast Charging, Up to 1000W Output Solar Generator (Solar Panel Optional) for Outdoor Camping/RVs/Home Use

I purchased this EcoFlow portable power station in January 2025, and I’ve used it every day since then. I originally bought it so I could keep my work laptops powered while having the flexibility to move around instead of staying in one spot. One of the things I really like is that it doesn’t need to stay plugged in to operate—you can use it wirelessly and even charge it while it’s in use. I typically charge it after my workday, and it easily lasts through my full 8-hour shift powering three monitors the entire time. It also charges back to 100% in about an hour, which is impressively fast. It’s been very reliable for my main use, but it’s also come in handy for other situations. During a power outage, we used it to charge our phones, which was a big plus. The performance hasn’t changed at all since day one, which makes me feel confident it will last for years. The only minor issue is that it sometimes makes a noise during the day—I even recorded a video of it—but it hasn’t affected my work or caused any real inconvenience. Overall, it’s been a great and dependable tool for my needs and great value for the money that I have paid.

You will absolutely love this generator. I use it on my 12 V refrigerator freezer and lights and it lasts for two full days and nights. It’s great to have on the road. You don’t have to worry about the electrical problems, fast charging I wouldn’t use anything else. great power back up. It’s convenient and long battery life

I intentionally waited to write this review so I could test it in real life scenarios that I personally would want this solar generator for. It is a beast for it's size and for how quickly it can charge. In my video you can see that my street fighter 2: hyper fighting arcade cabinet will run for over 4 hours on 28% battery. I later on charged it to full and it gave me over 17 hours of run time. I even played games for 3 hours to make sure there was no shorts, cut offs etc, and it ran flawlessly. Next a ran a large tunnel fan. It ran it for about 2 hours without issues. I then moved on to my actual PC and monitor. I get a little over 2 hours of use with this generator at full which doesn't sound like alot but bare in mind that I got this for $200. My next big test was my Playstation 4 and projector. It handled it better than I thought at almost 3 hours!! Simply amazing. It takes about 57mins to charge it from the plug. I tested multiple solar panels for charging as well. I tried a 100w portable panel and an actual 100w panel. It does take about 5hours to charge solar with both and about 7 to 9 hours with 1. However, I was also charging a power bank with it while solar charging thanks to the pass thru! This is an absolute must have! If our grid ever goes down I will be watching movies, refrigerating food, playing arcade games, trying to live life and enjoy some of the luxuries as well! My kids will thank me for being a pepper! This will run all your lights and everything else in a camp site as well with total ease. Trust me, I wasn't paid in any way or receive anything for this receive anything in exchange. I wanted to write this so if someone is on the fence about it , they could rest assured these things are real and can save your life. The absolute ONLY drawback is that I couldn't afford a larger one. Even the 256wh version is a must have. The bigger you buy, the more stuff you can run longer. So if you can afford it, grab a nice big one!!! Thanks for reading. 10 out of 10!!!! Also. The display is nice and bright. Can see it in the summer sun.

Works very well I am pleased

I’ll be back to buy more! This makes for a great power station for 1.5-2 days camp trip. The EcoFlow app is wicked cool as well. Can’t recommend enough. SUPER FAST CHARGE TIME.

UPDATE: August 2025. After about 1/2 year of use - about 5 days / week since March/April - THIS SOLAR PANEL has dropped to BARELY 50% of its rating. It is clean and undamaged, but won't put out more than 85 W (160 W rating) So ... my solar experiment has pretty much ended. This "solar generator" is an excellent battery, and I use it almost DAILY. It has powered our refirigerator and freezers through power outages witih no problems. I use it as a power center to keep ALL of my portable devices and small power banks charged, as well as 18v batteries for hand tools, and 40v batteries for yard/garden tools. Comes with a variety of charging options, and I've used them all now. Car charging yields about 5% charge in 20 minutes off the 12v connector in my truck. Will top up from 70% or more using household current VERY quickly, faster than 1% / 10sec. Less than 50% remaining and it charges a bit slower, but still very quickly. About 20-25 min to full. HOWEVER, the Solar Panel is the WEAK POINT. It is a 160w SOLAR PANEL but delivers NO MORE THAN 120w at it's best. It folds better warm than cool, and the connectors are awkwardly placed for storage. The panel's storage/carry case is well-constructed, but needs pockets for cables. Connectors are good enough and the attached metal legs are workable. I am in SoCal and even with my electrical rates, this little kit will NOT pay for itself in 3 years. Am I glad I have a "solar generator" ? Yes. It travels well, better than a gas model, and can be used indoors. BUT you will not get the "run time" of a good gas inverter, and the purchase doesn't "make sense" on strictly economic factors (mine were not).

Powered my CPAP for 3 nights with enough for around six more hoiurs. I was powering it about 9 hous a night. Much better than the no name brand I bought a year ago which would go one night and then the CPAP would say "check power supply". That has never happened with this battery. I should say this is using a 12 volt power cable and without a water reservoir connected.

I have taken this on two camping trips and absolutely love it! The second trip I brought a portable 102" movie screen to watch movies on. I charged the laptop ahead of time using the Ecoflow while it had the solar panel charging it, then at night it ran the projector and speakers no problem. My son even ran some COD from his X-Box on his Ecoflow. After first two movies we watched, it still had 32% and 46% charge at the end. One day it wasn't fully charged when we started. The last day we watched Straight Out of Compton which is about 2.5 hours. It was pretty much dead after the movie, but we finished it fine. The next day it charged back up to 100% using the solar panel in 5 hours, but that was also charging the laptop and some lights / phones, etc.. When not running a projector, this will charge all your devices, lights, laptops and such and still have plenty of charge. I even ran an electric chain saw on it. It works, but you can't push it too hard. This is small and very lightweight. I 100% recommend this to anyone that is looking for a power source while camping, traveling, or even just as an emergency backup.

Atendieron perfectamente el problema que se habia presentado, y ahora mi estacion de carga se comporta super bien. Recomiendo mucho el servicio post venta y el equipo.

I paired the EcoFlow RIVER 2 Max with the 160W solar panel, and the results are outstanding. Even on cloudy days in Ontario, the panel delivered enough power to cover my 60L fridge's consumption while simultaneously charging the battery. The XT60 input is super efficient, and the River's built-in MPPT controller makes the most of every bit of sunlight. In just a few hours of direct sun, the battery is back to 100%. It provides the ultimate peace of mind for off-grid camping without ever worrying about finding a wall outlet. Highly recommended for any serious camper!

I've had this for 2+ yrs. I use it as a power backup for my cpap machine so it's in use all the time. I also take it camping and I get a full night with the cpap machine and 2 cell phones plugged in. Im really impressed with it.

Para ir de día de campo y conectar pocos dispositivos está bien, yo lo compre para utilizar como medio alterno de energía eléctrica en casa pero la app no funciona como dice y tengo muchas intermitencias, si lo conectas a la energía eléctrica te hace un puente y si está falla también te falla tu conexión, no es como un no break, lo compre para starlink y no me funcionó, tuve que meter un no break y a veces también por las variaciones de voltaje me falla. No hay reembolso o cambio, me mandaron una guía pero no pude regresarla ya que vivo lejos de paquetería pero no me dieron guía de recolección. Desde mi punto de vista no pudieron resolverme. Cuidado con eso.

Handy. Light. Keeps charge.
