XINPUGUANG 200W Foldable Solar Panel Charger for Portable Power Station & RV Battery, Compatible with Jackery/Roackpals Generator, with 20A Controller for 12V Battery RV Boat Camping

I bought these _hoping_ they’d get 75-80% of their claimed power output, but found they got nowhere near that in optimal conditions (about 47%). This is essentially a 100w deploy, not 200.Within the first hour of having them in the sun, they started delaminating. I took several photos over the following couple of hours and was able to track its progress as they deteriorated. I’m not sure they’d last a solid weeks worth of use. The power output continued to degrade over the two days I used them.Lastly one of the terminal connectors fell apart. The coffin nail in an already-established bum purchase. I have a lot of experience with many different panels and can confidently say these are the lowest of quality I’ve worked with and do NOT recommend them.

Purchased two(2). I know I was all in. Trust or full faith or whatever you want to call it.Problem #1: One of the two units had blank display and "zero" output. I contacted them and they promptly send me a new PWM controller. Still same problem after the new controller was installed. After many trials and error, I narrowed down the problem to one of the Anderson Connectors. No connection unless you held it at an odd angle. Replaced the connectors and all was good.Problem #2: Under the full sun, both units briefly output 100W each for few seconds. Mostly, they were outputting about 70W-80W under full sun at perpendicular angle. And yes, I was using 10AWG cables too even though the supplied cables were 16AWG. I do understand that many manufacturers often exaggerate their product ratings. But 70W-80W from 200W?Problem #3: On the 3rd day of field use while camping, one of the two panels developed blisters in the dead center and stopped outputting juice. DOA. My wife said "maybe it got too hot in the sun?" And I thought maybe? But these are solar panels, right? They are supposed to live under the sun. And I was only getting full sun on these panels for couple hours each day because our campsite was heavily wooded and only had full sun in one spot for couple hours. So it's not like I baked these panels for 12 hours in Arizona. My campsite was in Northern Virginia in mid-May.Bottom Line: These should be sold as 100W and need better quality control.Suggestion #1: The center storage pocket should be eliminated and allow the connector to hang out to the side and not get sandwiched between folded panels.Suggestion #2: The center pocket should be removed to allow the Velcro stands to be positioned in the center where the pocket prevents it as is now.

Real happy with the extremely portible 200 watts for charging solar generators at camp site or at home under power outage. After first use, I noticed a little warp on the panel with which the accessories were stored. Don't know if it was the heat from laying flat and then folded back while hot. Have to learn to take care when folding after for storage. It is very thin. It does work great and the output is comparable to the effiency of my other brands of portable panels.

I had this out at noon in July. High directly over head sun and it put out 71 watts. Poor performance.

Well my car battery died on an adventure i was stoked to use my solar panel for first time and glad i had itThen the charge control part dosnt work and i was stuck out there for 1 day and had to walk about 10 miles to find a jumpWould be epic to get a new solar charger conrol pannal thing and take it out agin to see if it works
