Great solar panels!!!!

Lightweight easy to install works great even on Shady days have it inside of my motorcycle shed produces power as if it was in the Sun just from the light coming through the shed excellent stronger than I thought it would be highly recommend this brand solar panel also have 100watt suitcase excellent they are both great solar panels highly recommended...👍

Works great

This is a high quality product. Some reviewers stated they were unable to measure voltage and thought the product was defective. The solar charger will produce current when connected to a battery - I was able to measure current and voltage consistent with manufacturer's specs. Overall good value for money. Will help keep the car battery full when I am not able to drive for days or weeks due to working from home.

Works like it is designed to.

This is my second Renogy solar battery trickle charger. I am still using the first one that is 4 years old. I just found the occasional need for a second one. I would not recommend leaving hooked up all the time. And don't expect battery to be charged in just a couple of hours. I like the choose of connectors provided. The ring terminals in the on adapter is the right size for atv/utv/motorcycle style batteries. If this charger is used like they are intended to be used you should be pleased.

Renogy 10 watt battery maintainer. Excellent!!!

Ive been using this for a few weeks to maintain an RV battery system. It was very easy to use and works excellent... tried other brands before that just didnt cut it. I also heve the 100 watt suitcase from Renogy which is also a great item. Totally recommend Renogy products.

Great for local camping

This solar panel worked perfectly for charging a couple of 12v 7ah batteries for camping. Heck, it would probably work great for charging up a deep cycle marine battery for camping too but I haven't gotten that far yet. It was durable and handled rain like a champ. The connectors are special, so make sure you plan for that. I think my husband is going to steal this from me to keep the boat batteries topped off while not in use!
