THIS IS EPIC!!
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.

My go to power source now
I have had the River 2 Max as well as a River 2 for a few weeks now. I have been around portable power stations, batteries, solar, and generators for a long time and have been waiting for a portable unit that used LiFePo4 batteries for awhile now. I currently have an 8.64Kwh LiFePo4 battery bank with inverters for backup of may whole house, this can be vital during hurricane season, though it's not portable in the least bit. I am very picky about my power quality and do not tolerate simulated sine-wave inverters, so I was excited when the new River series was announced featuring both pure sinewave output as well as LifePo4 battery chemistry. My last small power station used a lead acid battery, had limited solar input ability and only 120w inverter output, though it too was sinewave. I used it for a few years before the battery gave up ( as lead acid batteries do) and have been looking to replace it for some time. I have been doing a few craft shows recently and wanted power for my tent, power connection at these events costs a fair bit and can reduce your placement options as you have to be along a side with power. Generators are not allowed due to noise and emissions, so a battery is really the only option. I used this at a show a week after receiving it and was beyond thrilled, it powered the lights in my tent along with keeping my card machine and phone charged and could have done so for a long time. The river series is small enough that I can just put it in a bag and bring it along without worrying about it taking up space that I need for inventory, stands and tables. When not doing shows the versatility keeps it from just sitting on a shelf also, I have tried this as a UPS for my full computer desk setup and it switched over flawlessly without any of the devices even noticing power had gone out (unplugged from the wall) The fast charging is amazing, rarely does a power emergency happen when I'm prepared and I can be quite forgetful as well, so being able to charge to full in the time it takes me to pack up the car for a craft fair is incredibly helpful. Charging with solar is about as easy as it gets, I have a couple of the 100w rigid Ecoflow panels and managed to get 201w out of them just laying them against the side of the house in the right direction. I also have the 110w folding panel and though it is a bit more effort to setup, it is super portable and has a nice case. The solar is actually so easy to use that I haven't been plugging my river units into the wall to charge, I have just been leaning a panel outside and charging them up in no time. I have actually found myself using both my river 2 max and river to charge my laptop and phone while working away from my desk, as its easer than reaching an outlet. only time will tell how everything holds up, but I am thrilled with the value I am getting out of these units right now.

Excellent Solar Generator (battery) ... paired with a WEAK solar panel.
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).

Not good for emergencies!!!
Don't bother. The company doesn't stand behind their products. I bought the solar generator for emergencies and it had a 5 year warranty. I plugged it up and it charged only to 27%. When I unplugged it didn't work or hold a charge and had no power. I contacted support they decided to give me and old refurbished one that someone else had. Which is unacceptable this defective generator cost me 699.00. If a true emergency had occurred I would have in trouble thanks to their faulty product and greed. As you can see as long as it was plugged into the electric socket the power was on. I unplugged it and plugged in a small coffee pot no power
