    • Excellence and reliability
Style: DELTA 3 Max Plus+400W
Personally, I really liked this ecoflow delta 3, excellent power can last up to three days of continuous use and more is only in the daily use they give it. Very practical since if you go on a picnic or to the beach you can take it with you.

I purchased this combo for the larger inverter and more solar input to power my camper and home office. This Delta unit is awesome. Its sleek looking and well thought out. The ability to harness 1000w of solar input via two 500w solar input ports is really cool (if one needed that much input). I set it up early in the morning so the solar conditions weren't great but I still got about 250w coming in. I can imagine having 2 of these panels in parallel for each port. That would safely over panel each solar charger while maximizing the input even during poor solar conditions. An obvious reality is the panel is quite large and heavy... probably the largest it could be and still be considered "portable". It took a little time to get it set up by myself. I suggest having a second person and/or patience trying to get it set up for maximum efficiency. I know there are already in-depth reviews for the D3M+ regarding capacity, efficiency, power, etc. I suggest reviewing those for complete analysis... but I can say so far I am super happy and excited about this Delta unit and solar panel. It will run my home office as well as my camper when I am away from home. I particularly like the new addition of the 12v anderson power pole they have finally included. That opens the door for much higher dc outputs. I have several Ecoflow products and believe these are the best units out there. Customer Service was wonderful resolving a couple previous warranty issues. No hassle getting replacement units / fixes rather quickly. I highly recommend. I would give more than 5 stars if it were possible. Great job again Ecoflow! ... show more

Very easy to use, well made and keeps my domestic 100 cold for days. I use it in my van for weekend - week long trips and it holds up just fine.
