EF ECOFLOW Portable Power Station RIVER 2 Max, 512Wh LiFePO4 Battery/ 1 Hour Fast Charging, Up To 1000W Output Solar Generator (Solar Panel Optional) for Outdoor Camping/RVs/Home Use Black

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.

I bought this portable power station to send to Cuba and it has been a lifesaver for my family. The battery lasts a long time, it charges quickly, and is very reliable during power outages. My relatives are so happy with it, and I will definitely recommend this brand to others and try more of their products!

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....

“The EcoFlow power station is amazing! Compact, powerful, and easy to use. It charges quickly and runs all my essential devices without any issues. Perfect for home backup, camping, or emergencies. The design is sleek and the battery lasts a long time. Definitely a must-have!

Our primary use is for camping, to power 2 CPAP systems, tent lights, and to recharge phones, etc. This unit works well in this use case. AC charging is as advertised. A fully emptied unit will charge in about an hour on AC. Solar charging really depends on the amount of sunlight, but is significantly slower than AC.I ran a small 110vAC crockpot, which pulled 75w(low)/140w(high), while on solar panels bringing in ~73W, so it's possible to charge and use power concurrently.The unit is lightweight, as compared to a marine deep cell battery, and is comparable to other LiFePO units.One drawback is the lack of wireless charging for phones, etc.
