When the celestial couriers of Earth’s marketplace (whom the humans call “Amazon”) promised the arrival of the ECOFLOW Portable Power Station RIVER 2, I prepared my ceremonial waiting circle. But lo! It arrived before I even finished my summoning chant! Truly, the delivery was swifter than the winged chariots of Ur-Zog.
Upon opening the sacred box, I beheld a design so sleek, so divine, it must have been forged in the glowing depths of a neutron star. The smooth edges, the gentle glow of the display screen—it spoke to me. Not literally (yet), but I believe it is waiting for the right solar alignment.
Speaking of solar: it came with a 45W solar panel, a flat talisman that devours sun-rays with the hunger of a thousand suns. I placed it outside and whispered the ancient phrase, “Please work.” The power flowed in. My devices—flashlight, phone, even the ritual taco heater—came alive. It was as if Ra himself approved of this purchase.
Now let us speak of coin: it was affordable. So affordable, in fact, that I feared it might be cursed. But nay! No hexes, no mysterious plagues, not even a single puff of blue smoke. Just clean energy and the mild scent of technological destiny.
In conclusion, if you wish to harness the sun, power your artifacts, and perhaps open a tiny wormhole to charge your sacred blender—this is the one. Praise be to ECOFLOW, and may your outlets never flicker again.
Highly recommend for fellow stargazers, doomsday preppers, and ancient astronauts alike.
I also decided to purchase the bigger power station, the Delta 2 to run my refrigerator. I did a practice run on Saturday and ran the refrigerator on the Delta 2 from 2:30pm to 9pm. 6.5 hrs and the Delta 2 still had 55% battery remaining.
The Ecoflow River 2 and Delta 2 will work for my needs. The power should get me through the night. If the power is not restored overnight, I can run to the local Starbucks or McDonalds and plug in for an hour and both power stations will be 100% charged. I did not purchase the solar panels yet. Both power stations did come with a car adapter plug. I'm not sure how long it would take to charge from there.
I am just a regular guy. I know I'm not the only one that uses a CPAP at night. And I know I'm not the only one thinking about groceries when the power goes out. These are my real life uses for the power stations and thought I could share my experience
I just started learning about Portable Power Stations and the LiFePO4 Battery.
I had a important need for auxiliary power. I am on a CPAP every night. I had power go out and no way to use my CPAP. This is a life saving medical device for me. I needed a way to power the CPAP at times my electricity was off.
I had enough bottles of oxygen to make it for a couple of days, but couldn't use my CPAP. I needed a power source for at least seven hours. So I purchased this EcoFlow River 2 Power Station. When it arrived I charged it to 100%. That night I hooked up to the EcoFlow. It lasted a full seven and a half hours. That's what I needed.
So the next morning I charged it up. It took about an hour to be fully charged. It is small and light weight. It weighs less than eight pounds. Size is: 9.6"L x 8.4"W x 5.5"H. The RIVER 2 Power Station came with an AC Charging Cable for charging in the house, and a DC Charging Cable that works in my vehicle, and an Instruction Manual. It doesn't come with a Solar Cable, but they are available. I have Solar panels on my house and possibly we could tap into that to charge this Power Station.
The Long-Life Battery has a ten year expected life rechargeable to at least 80%. I'm 82 years old and the Power Station should last longer than me.
I'm so excited about this Power Station that we are considering a full home backup system. I'm currently looking at the ECOFLOW DELTA Pro Ultra Power Station, with 2 Batteries and a ECOFLOW Smart Home Panel 2. This should give me all that I need to fully power my home. I need to get some help in determining that the DELTA Pro Ultra will supply all of my needs.
These LiFePO4 Battery Power Stations are very interesting. This technology is great.

STATE OF THE ART POWER
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.
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.
