One of the worst items on the market.

This is an item that should not even be on Walmart marketplace. This item is nothing what is described. This is in no way a 300 W solar charger. It may be puts out 20 W and is good to only charge. Maybe a cell phone. It is poorly describedthe manufacturer and seller are lying to the public into the Walmart marketplace.
