Description
How long can the RIVER 2 Max 500 power my appliances? Run time≈ 499Wh*0.85/operating wattage of your appliances. Can RIVER 2 Max 500 be used as an uninterruptible power supply(UPS)?

Set name: RIVER 2 Max 500
I've only owned this power station for a few weeks, but it's already proven itself useful enough that I don't regret buying it. The first real test came when I needed to charge the battery on my ATV, and this unit handled running my battery charger without any problems. It honestly ended up being a lifesaver because I didn't have to drag extension cords halfway across the property or move equipment just to get power where I needed it. One thing I especially like is how portable it is. It's easy to carry where it's needed instead of bringing the project to the power source. The fast charging is another nice feature. Being able to recharge the unit quickly makes it much more practical than waiting all day between uses. The display is also simple to read, giving a quick look at battery level, power input, and output without making you dig through menus. I haven't owned it long enough to comment on long-term durability or battery longevity, but the early experience has been very positive. Based on what I've seen so far, I can already tell this will be useful for camping, power outages, charging equipment around the property, and all those situations where you need electricity somewhere that doesn't have an outlet nearby. Overall, this has made an excellent first impression, and after only a few weeks it's already paid for itself by getting me out of a bind when my ATV battery needed charged.

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.

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.

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.

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

Set name: RIVER 2 Max 500 + 160W
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).

I bought the River Max 500 last spring and have used it a few times. We have taken it camping with us a couple of times now and it was very useful. The camp ground we go to is about 3 hours away and doesn’t have much around it so we use a mini fridge. The River Max powered the fridge all the way there and still had a lot of power left. We were actually trying to drain the battery (it says to drain it completely at least once every 6 months) so we changed 6 phones and even ran a projector on it and it still had power. I would definitely recommend this product for everyone. I also like the fact that it is fairly lightweight. As someone with a disability I can’t lift anything really heavy but I have no problem carrying it around. With the extreme weather knocking out power it is definitely worth having it. I hope to one day get the Delta as backup power for my house but for now the River Max is working for me.
