Awesome panel...

Finally I was able to use this over the weekend and I am impressed on the performance. I was able to fully charge my Eco-flow Delta Mini while using my fridge. So I will be traveling to Moab in the next couple weeks and I am excited for I know I can depend on this. I will further update my reviews after my trip so stay tune and for now I can highly recommend it.

DELTA 2 MAX MEETS OUR NEEDS

We purchased the Delta 2 Max as an alternative to an overhaul of our RV's electrical system. We've used the unit a couple of days and it looks like it will be sufficient to enable us to boondock for two to three days. The case is sturdy, well made and not too heavy given the performance of the components. The app / smartphone interface is great.

Portable charging power for small stations.

Light/portable. Set up is a little wonky. Could use some better instructions. In full light and the correct angle, output was right around 100w. This panel would be great for temporary charging of a small EF station (River or Delta), and has MC4 connectors plus an mc4 to x60 adapter.

Ecoflow is a powerhouse!

I have three ecoflows. Two Delta 2 Max and one Delta mini, I bought them because we have frequent power outages. They are a great option when power is out to run essentials. Performance is awesome and I intend keep adding more units to my house. These things are built like tanks.

Great product

I bought the EchFlow Delta 2 Max with an extra battery. Looking as a backup power source when/if the power goes out. Tested it on various small to medium household appliances and it worked excellent and charged it up every fast. Ready for another use. I also bought last year the Delta Pro with two extra batteries was able to power two refrigerators for 24hrs before needing to charge. Looking forward to making some solar panel purchases next.

Pretty Cool

I haven’t finished all of the tests but so far going really well. I ran a test to see how long my fridge would run off the battery. The battery made it 19 hours and estimated it would make it another hour. I got to 8% capacity left. Plan is to next run the battery down with the freezer. Then will recharge for the first time using my 400 watt solar panel. Figuring I may want to get a second 400 panel later. The display is great. All good information. The App is awesome for sure. Can be wherever and see progress. Glad I finally made the purchase. The sale helped push me over the line. Great addition to my power down preparations.

like i but.....

I bought 2 of the pro max 2's , like them will work for my green houses during the summer but......will only run the 1500 w heater for about 2 hours. NOT ecoflow fault it's mine did not do my research heater draws 12.5 amps on full setting so 2hrs at that current is not so bad. would buy the pro max 2 again may even get the batteries for the unit.

Nice off the grid power generation on sunny days

Excellent quality solar panel. Light, portable, easy to use, and connect. Works as expected and slowly but steadily charges my power station when in the sun. Note that the panels need to be in direct, full sun. Partly cloudy days will reduce performance dramatically and I didn't see any power generating happening when clouds were in the way.

Another great eccoflow product!

I've had my delta 2 max now for 3 weeks and so far I'm loving it. It's a little more heavier than the delta 2 is at around 50 pounds vs 28 for the delta 2 but not to heavy for me to carry it around without a problem. I've used it to power various appliances around my house such as a microwave oven, a convection oven, hotplate, hairdryer, space heater and a room size air conditioner and it's handled everything like a champ! The fans are alot quieter than the delta 2 fans also. The fast charging is nice at around 10% it took a little over a hour to charge to 100%. I love the eccoflow app too! It puts everything you need to know about the unit and what it's powering at your fingertips. Overall it is a great unit with lots of awesome features and works really well for what I use it for. I am well pleased with my purchase and would recommend this product to others who are looking for a portable powerstation.
