EcoFlow RIVER Max Portable Power Station

Quick delivery, and customer service is great.

Idéal pour conserver le frigo à compresseur en route à l'occasion de nos road-trips

Just love it

I bought the river max for a world bike tour to keep my electronics charge. I’m installing a solar panel on my bike trailer to keep the river max charged while cycling. It might be a little over the top for my needs but at least I know I have a great product with plenty of capacity.
I have had the river max for a couple of weeks and I have been using it at home testing out how long it takes to charge my electronics. I must say I am more than happy with the results.

Everything’s went well, only the capacity is belo 576 kW, but still ok

Perfect
quick delivery.
very good material.
very satisfied with the product
I recommend

Très facile d'utilisation, conforme à la présentation commerciale. Produit de très belle finition

really good product

Customer service: very happy with the help I was given by one of the person’s working for EcoFlow, since I had a little difficulty locating my package after it was delivered to one of the Package stations in my city. But the help I received for locating it was clearly showing me a desire to help me.
Product review: So far I am very happy with it. It still needs more time and testing to really know my level of satisfaction with it, but the result of that testing phase will be too objective to apply it to the purpose someone else will buy the River Max for. I personally need it to power a monitor while on a job. All the feedback I have based my purchase on from collegues in the industry have been satisfied with this machine.

Good product. Excellent backup power. Extra batteries / battery pack if needed.

Works great, worked for hours and hours.

I like for most small items cell,iPad etc, could hold a charge longer on the 110 v plugs

This is my go to power station it can handle all my needs. I'm from Louisiana and this was great for hurricane Ida. If I had to do all over again. Wouldn't change. Love this product

I have several portable battery packs for public service events done on often remote locations. My EcoFlow River Max is the best. A recharge on AC from zero to full in less than 2 hours. Wow! My smaller batteries take much longer. The EcoFlow handles multiple connections for recharging easily. I am looking forward to recharging it from solar panels which I expect to swift. This EcoFlow is an absolute must for for emergencies and for camping.

works for me

It's easy to run.

The fast charging separates this unit from the other brands. Tested on several things around the house and works great.

Very portable and easy to use.

very useful

I love this product .easy to use ,works for exactly what I need and I have plenty of time with the battery to do what I need to do and it seems to last for a long time.

Charges fast and its light weight so glad I bought it!

I love this product very light for power and I have paired it with my Ecoflow Delta to power my Van Build. Including, water pump, water heater, lights, fan, and a dump valve.I'm adding some solar panels for charging and it is working great for my short 3-4 day trips.:)

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....

Very quick to replay when issues arise.

It is light enough for my wife to pick up. We will use this battery to keep phone,laptop and even a small fan going during storm related power outage.

Se transporte bien

Very nice, cost a bit more than some other units with about the same spec's but it more than makes up difference. Have a different brand that I have been using for over a year and could have just bought another one as I have been pretty happy with that unit and the price is better. First the info on the display is much more accurate second the inverter is larger I can use this with my egg cooker , rice cooker and my slow cooker third it has more solar input for changing . the app is great can check out the rate of charge how many watts are going in and can set it up to stop charging at 80% to prolong battery life . Also has the quick charging when plugged in to the wall not something I plan on using but can see the advantages of having it with rolling blackouts that are becoming more common place! The only minor complaint looks like a small stress mark in the handle but doesn't seem to affect the strength in any way. Overall this much better quality than the other unit and has a longer warranty also!

This unit does what it claims it can do. The best feature is the quick charging, blows away competition wrt charging time.

Fast charging (under 2 hours). Long lasting. Superior to my other solar charger. I mainly use it to charge my portable freezer when my truck is parked.

I took this on a bike camping trip recently and charged it during the day with a 160w solar panel, then recharged an ebike at night. Worked perfectly. After the trip I needed a replacement due to a mistake I made with the device and the support was quick and helpful getting me a new unit without any hassle. Surprisingly the app also works well.
