Great quality, like is expected from EcoFlow.

I have ecoflow products since the early stages of the company. They just dont came with a great new ideas, but the focused on quality. And on top of all that, the support were always great. This portable panel is not an exception. The quality is great. We are using it as an extra source for our van conversion (we already have ecoflow panels on roof, but for adding extra input when needed)

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.

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.

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

Excellent Product

As expected a little smaller than my 160 Watt panel I got with my generator but the two connected together will work fine. VERY impressed with Ecoflow and would highly recommend them for your back up power needs. Works so well we're considering Solar for our house.

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!

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

Top of the line unit

I bought this one after watching review videos of different solar generators and comparing specifications. This unit was by far the best option with its lithium iron phosphate battery. I'm a beginner so I've been testing different items around my house to get comfortable with it. I'm planning to take it camping and use the solar panels. Really happy with my purchase.

PG&E Alternative

Recently experienced nearly 24 hour power outage; my brother kept refrigerators, etc. going at his house for several days with only a two hour charge of his DELTA 2 Max unit at my house when power was restored. Long story short, I ordered the DELTA 2 Max and additional battery; of course I haven’t needed my system yet, but it’s nice to feel prepared. Shout out for the prompt deliveries of both components.
