Bests & Worsts Reviews from Amazon

The device is nowhere near 200 W. I set the solar panel up right next to my other one which is 135w rigid solar panel that weighs a lot. At the time of testing, the solar panel put out 4 amps of power to the battery. My other solar panel put out 6 A of power. My old solar panel has the same connectors, so I was able to utilize the same charge controller. So the charge controller was not the difference. I guesstimation is this a raise more like 100 W.
