Style: DELTA 3 Max+2*220W Solar Panel
We were looking for some solar panels and came across a great deal on Amazon with the Delta 3 Max with 2x 220w solar panels that we couldn’t pass up. We have several EcoFlow products and they’ve served us well, so we didn’t hesitate to purchase more, as we have uses for them all. The 2 220w panels give us more flexibility as they can be run in parallel or series, and one of them coincides with the input wattage of our River 2 Pro, as well. The Delta 3 Max is a nice compromise between capacity and size. It is a decent amount larger than the Delta 3 (both pictured), but not that much bigger considering it has double the runtime. It has all the ports you’d expect: AC, USB A, USB C, 12V DC, and Solar (XT60). The USB C ports are enough for our needs (Laptops, iPhones, iPad, etc)., as are the others. For those needing more umph, the Max Plus offers a little more max wattage, an Anderson port, and extra solar power input capacity. The EcoFlow app is very convenient, especially when we’re in the Jeep and running the Alternator Charger. It allows you to view and control all your devices, control the input/output voltages, and keep an eye on things. I’m really happy with the whole setup and look forward to our next camping & off-road trip. EcoFlow products have been amazing for us and I definitely recommend them.

This is a great product. I immediately plugged it in and charged it to 100%. Then I ran the fridge freezer on it for 16 hours, next day I put out the panels and charge to 80% after 6 hours. Working great. Recommended

No manual included. Have to download. That will be tough if there is no power. Unable to register for warranty. Requires copy of receipt. Ordered from Amazon and they don't accept credit card statement.

Worried about a long power outage ruining the contents of your refrigerator? This power station with 2 huge solar panels will put that to rest. They say it's portable but hefting in at close to 50 lbs., I won't be taking this out on the road. That's not a complaint but praise for a small unit packed with enough batteries to keep my food cold as long as the sun shines once in awhile. The only ding against this pairing is the adapter cable to attach the solar panels to the power station. It is NOT included and must be ordered separately from EcoFlow.
