I bought this EcoFlow to send to Cuba, and it turned out to be one of the best purchases I’ve made. It has worked amazingly well and has been extremely useful during power outages. It’s compact, easy to use, and powerful enough to keep important devices charged when needed. The quality feels great, and it gives a lot of peace of mind knowing my family has a reliable backup power source. I’m very happy with this purchase and would definitely recommend it to anyone looking for a dependable portable power station.

I'm very happy with this model. I charge it with a solar panel and use it to charge phones and computers in the home. One piece of advice if you are charging one by solar is you need to use a solar panel arrangement that supplies at minimum 25 watts of power or the battery doesn't consistently recognize the charging source. I was using a couple 25V panels for a year that were not from Ecoflow and they were not very efficient, giving 18 - 21 watts on a good sunny day and charging was inconsistent, and took all day to charge the battery. Plus the DC charging mode in the app where you choose car charging or solar charging didn't seem to be working as solar would just vacillate up and down and not set on a level of watts input. I recently got a 60W panel from Ecoflow and it charges in 2-3 hours in varied conditions, from partly cloudy to full sun, much better. Now the solar charge setting in DC mode provides a consistent charge level. For output it gives 5 laptop charges or 20-25 phone charges. Don't expect to power high wattage appliances with this, like an AC or microwave or blender.

So I bought this because the company had good reviews and I really liked the idea of having a portable power station to charge things on the go, but also have it serve as a potential POOP-HITS-THE-FAN emergency backup to power a fridge or something for a short time. It's clearly under-powered for that sort of thing, but it still COULD do it. I like that flexibility! Lo and behold, it has started to change my entire life! Suddenly I realized that I could have electric power in that old tool shed that has just served as a storage bin for old toys and mowers. That inspired me to clean up and order the shed, to put in shelving, and more! A few weeks later I also bought my first e-bike, and now I can store it in the shed and recharge the thing without navigating through the garage or removing the battery. This little unit is definitely too small for what I use it for-- it probably has enough juice to recharge 50% of my e-bike in one go, but that's OK! The unit itself is so compact that its easier to charge IT back at the house than move my tools or bike to where the electric is at. That's the beauty of this technology! After a few days of doing that, I realized that there was an even lazier solution I could use: solar! YEP, I could hook up some solar panels on that same shed and it'll recharge the unit automatically and, essentially, my shed is both off-grid and fully electric. I appreciate that it does all of the technical stuff I don't understand, so I just plug in the solar panels and it converts that into sweet, sweet tool juice. The app is also absolutely fantastic- It's fun to see how much it is charging or discharging at any given time. This has inspired me to buy the much bigger brother, a Delta 2, and a 160 watt solar panel to really complete the job. My plans for that are outside the scope of a review of the River 2, but it's worth mentioning that this little device inspired so much madness. So, in conclusion--watch out. This is a gateway device to much larger toys and an increasingly eco-sensitive lifestyle. EDIT: After enjoying this product for about six months now, I wanted to give a quick update. I still LOVE it, especially for the cost and size. It still powers my e-bike on completely solar energy. I use the Delta 2 to recharge this unit on overcast days using USB-C 100watt cables (ends up pulling in about 54watts), and that allows me to reap a little benefit from the Delta 2's 500watt solar input potential (the River 2 can only pull in 110watts max). Another thing to be aware of is that I did have some recent issues with the unit no longer displaying AC charging numbers and no longer pulling a charge through USB-C. This happened after a Firmware update. I contacted support, and the good news is that an updated Firmware update came out three days later that fixed these problems. It was over a weekend, so I didn't get a reply from Support until after it was fixed again, but it is something to be aware of. The Firmware updates sometimes bring new features, but if you have this as backup to a life-saving device, I think you'll want to time those updates to times when the impact would be lessened.

I got the ECOFLOW RIVER 2 (256Wh, 600W) because it was on a Lightning Deal for $157. Currently, it's available for $170, when a $70 coupon is applied - so it's nearly as cheap as when I bought it. Really, the RIVER 2 was an unplanned purchase, but the deal was too good to pass up. I've previously purchased a couple DELTA 2s, so I'm familiar with the brand. The RIVER 2's build quality is good, as are the controls, display, and operating ergonomics. The unit is very light, but the handle is still convenient. My use case for this is to act as a UPS for an NVR at my wife's salon/boutique. The NVR is just an SFF PC with Blue Iris installed. The power quality isn't the best, and there are the occasional power flickers that disrupt the business. The RIVER 2 acts as a UPS for the AT&T FIOS media converter, the NVR, and a PoE switch that's driving a number of WAPs and IP cameras. It's basically at the edge of its AC power budget - which is 300W (the 600W budget is the AC PLUS the DC jacks, FYI). Theoretically the runtime is about an hour, which is what I was getting with a 40lb lead-acid, line-interactive UPS previously. The only missing feature is that there's no USB/serial interface to interact with the PC - but that's not really a problem for me, as any outages tend to be seconds long. UPDATE: The River 2 has now had to deal with a number of outages in a short amount of time. No issues. I've reduced the SFF's power draw to the point where I have about 75 minutes of runtime. Just think of this as an inexpensive, line-interactive, pure sine wave UPS. Wow. I really can't overstate how impressed I am. Yes, something like an APS BE500G3 is cheaper, but I'm more interested in the River 2 as a more flexible/versatile solution. The PV input, carry handle, and generally more rugged construction make it worth the extra money. I assume my use case isn't typical. To try to make this review more helpful, I decided to try this unit with one of my solar panels. It was a little difficult to find anything that would fit within the narrow range of the solar charge controller, but I did dig up a 100W panel (~25 VoC). The unit was predicting about a 2 hour charge at 30% SoC, with 70-80W coming in. So, I think the main thing is price. At $240, I don't think this is a great deal. With the DELTA 2 routinely being on sale for double that, it's hard to think of $240 making any sense. At $157-$170, though, I think it's a pretty interesting device. Conditionally Recommended

I use my River 2 sinewave power station in my off grid shed for low power electronics, indoor light, and 40 watt spotlight with a 5 minute timer set. it works perfectly as intended especially when paired with 110w solar panel so its always charged up and ready to go in the future! Its a solid built device especially when used as designed to serve low energy devices. RIVER 2 has 256Wh state of the art LiFePO4 Battery and a method to rapidly charge in 1 Hour, that's incredibly fast against my older end of life portable power products. Another nice to have, River 2 also connects to an app via Bluetooth which means future updates and improvements. At the current time of writing this review, Jan 20 2023 At a price of $249 I'd say its a fair asking price for the level of features you'll receive investing in this unit. If sales promotions price dips to sub $200, id say that's incredible value and time to jump and that's exactly how I received mine. Undoubtedly this portable power station anyone can find a use; let it be located at your place of work or a gathering where AC power is extremely limited or not readily available to you. First I'll address the size, its light weight and easy for anyone to carry or move. that's due to limited capacity but for two hundred and change in US dollars that's the going rate of LFE battery at about 1 USD to 1 watt hour. LifePO4 battery chemistry has been the answer to longevity over its big brother Lithium Ion that's commonly found in your smartphones. close to a decade of daily use verses 3 years on lithium ion. I don't know about you, the time it takes to charge is very important and that's incredible value this kind of battery chemistry! The app, is so easy to use. Go to the Appstore or Play Store: download the ecoflow app. Its so easy to connect no extra accessories to buy in doing so, best of all its free. It shows everything for power details at the ports. The only strange bug I've notice is if the low power devices under 14 watts don't show the power draw just the remaining power. Last, the small power station noise level is not noticeably loud when the fan comes on to cool itself down. A huge important over previous power stations especially at nighttime. My advice, curb your expectations for use of this device. NO high end equipment, Its not used for your coffee maker, hair dryer microwave or small fridge. there are bigger models of ecoflow power stations to serve those needs albeit triple the price tag. 256 WHr isn't a crazy ton of power storage and it maxes out at 300 watt continuous pull with x boast feature turned off to keep sinewave protection for s. In fact when the inverter is powered on, the invertor function will consume about a quarter of the storage to produce 12v/5v and 110v power output. Best advice, keep the ports off in order to preserve its storage until you need it to serve it use! last and important review is on ecoflow customer support. Now everyone experience can differ, mine was surprisingly great due to ecoflow support going above and beyond to make the matter right. Using amazon support I ran into a promotion offer for the additional accessory. At first Amazon supports message came with no empathy and the attitude of your mistake, sorry but your issue and please go away. after three calls for the same problem I was finally put in touch with ecoflow channel using amazon chat and email service. ecoflow was prompt to answer and worked on it to make it right. the delivery was fast at neck break speeds as we grown to enjoy and expect. Would I buy another product from EcoFlow, YES absolutely. Would I recommend, Absolutely assuming practical use came up in topic Ecoflow features in a small package is incredible. My only disclaimer is the life of the product. Although LifePO4 or LFE chemisty is a decade of use, I cant claim this unit will live up to daily use of this since its really new. Fast charge im sure will impact the life cycle, the mppt, charge controller and inverters are all failure points, however with a outstanding 5 year warranty, i'll happy believe ecoflow will be around for the next decade to deliver on that promise.

UPDATE: 7.23.2024 - Battery never has held a full charge like it is supposed to. When I wrote the below review we hadn't used the battery other than once. We noticed it was discharging to zero within a few days (2-4 days) after a full charge. I hadn't owned one of these batteries before, but my son had and his did NOT do this. We weren't sure if that was normal or not at the time. We maintained it through the winter months and then went to use it for a camping trip in June of this year. It was fully charged before we left and after TWO days it was discharged down to 20%. We tried to play a movie on a TV/DVD 9V system (small) unit and it discharged and shut off before the 1 1/2 hour movie ended. We have kept the battery OFF fully, so that wasn't the issue, something is just wrong with this battery. My son's battery holds a charge and doesn't do this and so does the battery we purchased in after we had trouble with this one on our last trip. I know in the electronic world that things happen and warranties are needed. That's life. Support We contacted support. It will be 1 year on 8/22/2024 from date of purchase. I reached out in early June. I shared with them what it was doing and provided all the data they required. They sent back a list of troubleshooting things for us to do, which we did and it didn't change anything. They asked for all the SAME information again plus a video showing what was wrong with it. So far they have not honored the warranty. We will revisit this review when we know what the outcome will be. We are a bit bummed they've not been more helpful and the process has been a bit tedious and preteditive. We invested in EcoFlow solar panels when we bought this first battery and then bought another battery just like it, which does NOT act like this one. These are TOOOOOO expensive to have them not work out of the box or not have a warranty honored. Just a heads up to the consumer. ORIGINAL Post: We purchased this to take along with us in our RV to run some of the 9 V items in our 5th wheel. The new RVs don’t have 9v plugs by default any longer and we use them quite a bit for TVs and fans when boon-docking. We are in the process of upgrading some batteries and inverters and plugs to allow for this in our RV but it’s a spendy adventure. So I bought this as a backup emergency battery and to use in the mean time. My son had done a LOT of research for his van life batteries and has the larger size of this model and has used it the last few years with ease and dependability. It truly does charge fully in one hour. I was shocked. We’ve use it to run a fan and TVs in the RV nicely. You can see the power draw. It allows for Solar when we get to that. Overall it’s been a great add and I love knowing it’s there for emergencies.
