## Description

Solar Panel

Review: I bought one of the Enginstar 30 watt panels and was so favorably impressed I bought another, and then a third one when I found one on sale. I have other more expensive panels but these are the ones I hang out every day. I use them to charge two Samsung S25 smartphones, a couple of power paks and Eneloop AAA and AA batteries plus an 18650. The C to C output works great, but the regular USB works better than any of the other brands. If you try one of these, you will not be disappointed. They actually perform better than a $130 panel I bought from another vendor. I wondered about buying a $40 panel, but reasoned that no one is going to come to the market today trying to sell outdated technology. It appears I was right. I really like these panels.
Review: The big panels soak up a lot of energy, very reliable on a sunny day. On a very sunny day I was able to charge my phone then my headlight and my tail light for my bicycle and my portable speaker
