Fast Charging! I like my 400W Solar Panel. It charges my Delta Pro much faster that my 2 X 100W panels. It is a little big and heavy for one person to set up but I have gotten used to it.

Performs well and as expected. It has a good conversion rate/performance. I have good sun exposure most days of the year and can recharge in 4-5 hours when 2/3's expended. The panel array is heavy and awkward for single person manipulation. The panel array gets warm as would be expected in the sunlight and so if laid out over vegetation that you care about, (lawn, etc) it will burn the vegetation - I have had the same issue with a generic tarp on the lawn. So I purchased an adjustable stand that folds up and that solves a lot of the issues.

We have only used it twice but both times it performed as advertised. I may buy a second solar panel and run both for my new EcoFlow Pro...

A bit heavier than I thought it would be. But is definitely working well. Getting 400Watts as advertised!

Have not had a chance to use it, but if it works as well as my two 160 watt panels it will be just fine

We use this solar panel to recharge the Delta Max 2 instead of using a/c power, takes longer but it’s free power

Great panels. These panels were an upgrade from the 160W versions. These pull in so much more power for the EcoFlow.

I bought this about 2 weeks ago, did not open the box yet. I will open next week. Fast shipping. Thanks.

I ordered two of the EcoFlow 400W panels and they arrived yesterday. They are everything I expected from a great company with quality products.

These were easy to connect and so far work very well with no hassle. They pick up the sun as soon as it appears, even laying down flat.
