Works very well for my needs

I use this to feed my audiovisual/stereo systems. The electrical grid is very dirty and the power station generates electricity via an inverter. You might be surprised how much everything visual and audio benefits from clean power.

Power supplement for DC freezer

I use it to power a DC freezer. Usually plug freezer into ecoflow and plug eco flow into automobile dc. My viehicle doesnt supply enough for the freezer. I set the eco flow only accept 70 watts from the car. We drove for 8 hrs (with several stops). Eco flow lost 15% charge over all. Im happy with it.

Great little unit and great warranty

I love this little power station! The lifePO4 battery charges in an hour on AC you can use a solar panel (I tested with a single 100 watt panel so far) and these types of batteries last a long long time. EcoFlow actually warrantees this unit for 5 years, and you can register it for a coupon for future stuff in their site. I did that but haven’t used it yet. This unit is great for outside things (I use it for astrophotography) but too small for any home backup due to its smaller inverter. You’d need a delta series for that. But for a 500wh ish unit I am very very impressed.

It's not 1 kW; it's 750 W.

This product is not 1 kW; its maximum capacity is 750 W. Please don't mislead people. If I hadn't read the product specifications on the back, I wouldn't have noticed this detail.

Thank you for taking the time to share your feedback. We appreciate you bringing your concern to our attention.<br /><br />We understand how the product listing may have caused confusion. To clarify, the RIVER 2 Max has a 750W continuous AC output, which is its rated inverter capacity. The 1,000W figure refers to EcoFlow&#39;s X-Boost technology, which allows the unit to power certain devices rated up to 1,000W by intelligently reducing the operating voltage when appropriate. It is not the same as the unit&#39;s continuous output rating.<br /><br />We appreciate your comments regarding the product description, and we understand the importance of clearly distinguishing between the 750W continuous output and the 1,000W maximum device support with X-Boost. Your feedback has been shared with the appropriate team for review to help improve the clarity of our product listings.<br /><br />Thank you again for your valuable feedback. If you have any additional questions, please don&#39;t hesitate to reach out.

DO NOT ORDER FROM SAM'S CLUB ONLINE!!!

Good Product...BUT!--DO NOT ORDER FROM SAM'S CLUB ONLINE!!!...Especially if "ON SALE"!!! ONLY BUY IN STORE!!! Sam's Club does the DIRTY PRACTICE of "Advance Ordering" from 3rd Party Vendor (EcoFlow) and then drop ships ALL orders from EcoFlow!!! YOU WILL NOT GET YOUR ORDER "ON TIME" WHEN SAM'S CLUB SAYS YOU WILL!!! AND IF YOU TRY TO GET A "PRICE MATCH" OF IN-STORE PRICE TO SAM'S ONLINE??? THEY WILL *NOT* PRICE MATCH SAM'S CLUB ONLINE SALES PRICE!!! THIS IS DIRTY BAIT AND SWITCH SALES QUOTA FULFILLMENT TACTICS!!! IF YOU CAN GET IT "IN CLUB" AND IT'S ONLY $30 MORE, *DO IT!* OTHERWISE YOU WILL GET THE RUNAROUND SHUCK AND JIVE TACTICS!!! GET YOUR HANDS ON THE *PHYSICAL PRODUCT*!!!

Meager expectations, not met :(

1 star. First unit failed with a chronic "overload" error that would interrupt charging. Second/replacement unit has a faulty screen. EcoFlow tech support indicated the following, and I quote: "Upon evaluation, we have determined that the display is malfunctioning. However, this issue does not impact the normal charging and discharging operations of the device." And that was that. 1 star.

Missing a cable

Works. Failed to point out that the cable to connect to solar panels is an extra expense. I found this out in the instruction manual after unpacking the unit, even though the unit comes with a cabling for using 12 volt from the car. Product instructions are lacking.

Not for me

Returned it. Was not as functional as others in the same price range, i.e., Jackery, Anker

EcoFlow River 2 Max 500W

Couldn't run my fridge, as I'd hoped. Still, a very useful appliance to have, depending on your needs. Televisions use a lot of electricity, so are a good option that this EcoFlow could handle.

Homeowner

I have ecoflow bigger unit but this unit was a disappointment it would not even run a skill saw or electric blower with amperage low on the electric lower not worth the money.
