    • Small and powerful
Style: River 2 Max 500
Versatile power on the go or at your home. Various methods to charge this device. Lightweight and quiet. Good value for the price.

    • Strong when fully charged
Style: River 2 Max 500
Bought this to use to fill a very large king size air mattress while camping. I tested it at home and it worked. While camping it worked extremely well to fill, do an extra fill for firmness at night, and to deflate. All of that had very little drain on the charge. Maybe reduced the charge by 5% max. I was very pleased with the performance. Also it really does reach full charge within 1 hour! Amazing for the amount of power it holds. Cons - when fully charged and not plugged in it lost about 45% of its charge in about a week of storage ... show more

    • Updated - 2nd UNIT repaired & working well
Style: RIVER 2 Max Solar Generator+ 180W Solar ...
UPDATE 3-2-2022. I've been using the repaired River Max regularly now and it has performed well. I actually bought another unit a few months ago, so obviously I'm happy with these solar generators. UPDATE 9-7-2021. Added 2 stars. After receiving the repaired device, I'm feeling better about the Ecoflow River. They replaced a board inside and it seems ok after using it daily for several weeks. Not sure I'd buy another one though. There's a group on Facebook where a lot of people are reporting problems and having to return their units like I did. Really had high hopes for this company's products. UPDATE 8-18-2021: The display on the 2nd unit (the replacement for the 1st defective unit!) went bezerk & was returned a week ago. I just can't recommend this product to anyone now. A BIG problem is the time it takes to ship back & forth: almost a WEEK each way! And customer support takes a full day for response via email. They received the defective unit Monday & they said it'll take 1 to 2 weeks to check diagnose the problem & fix it, if that's possible. That means a full month without a unit I paid plenty of money for! Not a happy camper!!! I've since ordered a cheaper, different brand just so I'll have backup power. I CAN'T RECOMMEND THIS PRODUCT. UPDATE: Ecoflow replaced the defective unit and I'm very happy with it. Customer Service improved. Charges quickly and quietly with AC and solar panel. Love the display with all the info needed. I've tried using various items (nothing huge) with the River Max and everything works so far. Weight is kind of heavy for a senior citizen, so I'm using a small luggage cart that works perfectly. The app connected easily on my Android phone tablet. But since an app update yesterday, I can't figure out how to change temp display from Centigrade back to Fahrenheit. Hopefully it'll be fixed with another update. In short, I'm very happy with the River Max and would recommend it to friends and family. PREVIOUS:. So disappointed! After researching for a month & a half, I finally ordered the River Max, only to find that it was defective right out of the box! It won't charge, keeps shutting itself off within a few seconds after plugging it in. Tried using USB and AC ports, and they don't work for even a second. Dealing with customer service now about returning the defective unit for a new one that hopefully works! Will update after we see what happens. They claim it'll go through the "warranty" process. ... show more

    • Works for 8 hours with a cpap, buy solar panels separately
Style: River 2 Max 500
Review Image by Lady Katze Lady Katze
My bf uses a cpap. This had the plug in and fully charged will run his cpap for 8 hours. We just went through Hurricane Milton. This worked wonderfully for him and is charging so nicely in the sun we're charging other devices through it as it charges. It doesn't weigh a lot. You do need to buy solar panels separately. Totally recommend! ❤️ ... show more

    • Great Functionality and Size, but scheduling is not useful
Style: River 2 Max 500
I got this primarily as a UPS to keep my home networking and smart home equipment running during power outages. It's a bit overkill for this purpose, but works well - the switchover time is fast enough for my equipment. That being said, I was hoping to also use it for scheduling to run on battery at peak hours when power is more expensive, then recharge when power is cheaper. It doesn't seem to be able to do this based on the research and trials I've run, even though there are some implications that it should be capable. Overall, the size and capacity are amazing and UPS functionality is good enough for my equipment, but without useful scheduling capabilities, I can't quite give it 5 stars. ... show more

    • Does what it says*
Style: RIVER 2 Max Solar Generator+ 180W Solar ...
I give the River Max an *initial* 5-star review because - without really having used it yet - it does everything I want. After I've actually needed it, I'll update this review! I live on the Gulf Coast, where we usually have at least one power outage a year from hurricanes or storms. I have a 5kW gasoline generator (along with a xfer panel so it can power the inside outlets of my house). But fussing with the generator (especially if the power is just out for a few hours) is a pain, ESPECIALLY when you haven't had your morning coffee. (My wife has pictures of me turning on the generator JUST to power the coffee maker.) Enter the River Max. I wanted something that would (1) run the coffee maker in the morning; (2) power a few lights; and (3) run a fan at night if the power is still out (because I'm not running the gas generator all night long). After some initial testing, it does all three! (1) My coffee maker is somewhere around 1000-1200 watts. If you plug it in to the River Max without the xBoost function on, it won't work; the display says it tries to draw around 1100 watts and then signals overload. With the xBoost function, the coffee maker does work. The display says the River Max is sourcing right around 600 watts to the coffee maker. But wait...it requires 1200 watts, right? What's going on? I don't have a multimeter to verify the River Max display data, but my guess is that xBoost mode simply limits current draw so that the inverter doesn't get overloaded. In other words, it sources all the power it can, and the coffee maker just has to live with it. I wouldn't want to run the coffee maker all the time that way, but I can tell you that it worked (though it seemed a touch slower than normal) and my coffee was plenty hot. That's a serious win. Making one cup of coffee depleted the River Max from 100% to 85%. (2) I plugged in a 10ish watt CFL into the AC outlet and River said it would run for about 30 some hours. That's fine. We have battery powered lanterns, so whatever. (3) An old lasko table fan (no idea what the specs are on it) also worked fine. At full speed, River said it would run for 5-6 hours. But remember that running fans and other motors is hard on batteries because of the induction. (Look up power factor for motors - they draw more than they say they do, basically.) Still, 6 hours of fan time isn't bad. However, I ordered a 12V DC fan to use overnight (I'll update the review with runtime specs when it gets here.) In general, DC devices will run much longer than AC ones because inverters are pretty inefficient. FINALLY - in response to another review: yes, the River Max connects to the internet, and the app is pretty cool. However, contrary to what someone else wrote, you do NOT need to be connected for the device to run or to use the app!!!! There's a button (IOT reset) on the device, and if you press it, it'll let you connect directly to the device, no router needed. Thus, you can turn xBoost on and off in the middle of a camping trip. This takes me to my only complaint: the app is nice and well-designed. Still, there should be a button for you to turn xBoost on and off on the device directly. I shouldn't have to use an app just to make coffee. Still, this is the only portable battery pack I've found at its price point that can run a coffee maker. (Goal Zero, etc. can't do this!) It also charges insanely fast. In real life, once I got my generator going, I'd just recharge River from it so that it's ready to go in the evening. One other positive: they're really generous with cables!!! The River Max comes with: AC charging cord; solar cell charging cord; car charging power cord (you know, those cigarette lighter things); AND a USB-C to USB-C cord (for charging your phone); a DC to DC 15mm plug (or whatever it is); AND a USB-A to, well, some kind of Mac cable. it's dual-headed. One of them is a lightning connector, I think, and so I assume the other is another kind of Mac plug. (Obviously I use a PC.) Just go read about other brands, like Goal Zero, and you'll see they don't come with nearly that kind of cabling. For the price, huge win. So, tentatively, five stars. After our next hurricane, I'll let you know more.... ... show more
