Review on Travel Ready: ECO-WORTHY 120W Foldable Solar Panel Kit for Portable Generator Power Station. Includes USB Controller to Efficiently Charge 12V Battery. Perfect for RV, Camping, Travel Trailer, Power Bank, Emergency Power by Chris Norman

So far we have used it in our VW Westfalia during a week-long trip. We used it to charge a 100A hour deep cycle battery while our fridge was plugged into it. It wasn't a flimsy test, we had temps in the 90's and kept opening the fridge and adding hot water bottles so the fridge worked a lot. In addition, we accidentally blocked one of the vents, causing it to get hot, working too hard and consuming a lot of battery power. That being said, here's what I like and what I don't like at the moment. I needed something unobtrusive and easy to store as we don't have a lot of space in our van, this is perfect. It's about the size of a large briefcase but thinner when folded and easily fits in my closet or under my seat. It's lightweight, which is a must for my husband. After getting a 45 degree angle for maximum sun exposure, we hung it on the front or back of the van. Controller, that could be a disadvantage. This is a simple controller that only displays volts not watts and the battery level. It's attached to the back of the case in a zipped pocket, so you can't see what's coming out of your setup once it's set up. It would be nice if a Bluetooth model was included so you can track everything from your phone. So I'll probably upgrade the controller at some point. Updated 10/29/19. My brother stayed here and we hooked this up to his controller and the output was 65 watts in full sun. I'm not a solar expert but I was hoping for more than 100 watts, maybe I'm missing something but I was a bit disappointed. UPDATE 12/13/19, The company is very active. They have emailed me thanking me for my purchase and if they can help me in any way just let them know. Well, I took this opportunity to mention that I wasn't happy with the result. They sent me an answer very quickly and asked me to test the panel on cables with the controller disconnected. I was busy at work and then we went on vacation, then it started raining, they sent at least 2 or 3 more emails asking what I had learned about the panels. I don't know about you, but in my experience most companies don't care if they hear from you again. Customer service 5 stars! We finally tested them and the panels put out more than 119 watts! Perfect for a 120W system! Because of the controller I still give 4 stars and will probably upgrade to a Victron MPPT controller to be able to use as many watts as possible.
