Excellent!

I own 6 of these panels now. The are the most cost effective way to use solar to charge the River series and the Delta 2 and Delta 2 Max. by combining two or more you can get close to max charging on the aforementioned products. they are small and lightweight and, for me at least, setup is quick and easy. I just lay them on any flat surface, including the ground, and they just work! I have gotten 95 watts out of mine, but I am at a low latitude. Your mileage will vary! If you shop the Ecoflow sales and/or use ecocredits these are the cheapest way to power your systems.They are also just as easy to take down. I highly recommend these panels.

More ports for options to charge and to enjoy more

What are you waiting for, buy this now, double tx60 ports, meaning 1000 solar panels rating, car alternator charger up to 800 watts, stack additional batteries.

No sound at all. Perfect for vendor events.

I just used this generator at a craft show for the first time and I love it!!! Easy to charge, easy to start up with just the push of a button. It makes no sound which was very important to me. The only problem I have is that it is very heavy for me. I’m a small female and it’s HEAVY! It needs wheels and a handle so you can pull it.

Homeless

I use a gas generator in the morning to charge my Ecoflow River Plus. Then when the sun hits my solar panel it will keep up with most of my power needs until late afternoon when I need gas generator again. Solar panel not aimed directly at sun but I still get up to 77 watts input mid day

Great panels

I got the 110W solar panels to go along with my River power station. I tried it out at about 5pm and the input ranged from 70 to 90 watts. I mainly have the River Power station to keep my fridge running and devices charged during a power outage. When my fridge has the cooling system active it pulls about 50-60 watts and it only is in active cooling mode for 10-15 minutes every couple hours (depending on how much it gets opened). So in theory, the input from the solar panels should be enough to keep my fridge running indefinitely, which was my goal. The extreme weather events have been happening more and more frequently and several areas have power outages that last 2-4 weeks depending on the disaster, so I wanted to have the River power station and the solar panels as a backup plan. Thank you!

Recent 4 day power outage in hurricane. Kept my freezers going which are awesome freezers, cooling to zero snd holding for hours. Learned enough to know I need a battery as well and maybe I should consider the pro model. Glad I had the max. Easy to wherl around on a cheap luggage rack

So far so good, with one problem

I bought this and installed it into my daughter's bus. (Schoolie conversion) It is what we wanted. The only complaint that I have is the way the cable comes out the side. you cannot stack anything next to them within a foot. The wave has a nice 90 degree cable that goes between the battery and AC but the Delta 2's cable sticks about 6 inches out the side.

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.

Just what I needed

I live full time on the road and I needed 24-hour power to run my eco flow glacier cooler and charge laptop phone microwave etc I have a 400 watt solar panel from another company. I thought the ones on eco Flow looked kind of flimsy and had bad reviews. But anyway the Delta max 2 works amazing last 5 days on a charge, 5% charge to 100% in an hour and a half plugged in to AC. Also charge about 4 hours from solar panel. Very quiet hardly noticeable

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.
