Description
Equipped with premium monocrystalline solar cells, the Renogy 10-Watt Solar Battery Charger Maintainer manages your 12-Volt lead-acid battery in daylight conditions by converting the sunlight into usable electricity and maintaining a healthy state of charge. The built-in MPPT (Maximum Power Point Tracking) charge controller intelligently manages the charging process and improves the charging efficiency by 10% to 20%. The plug-and-play SAE connecter and included adapter cables make the solar battery charger maintainer a versatile fit for most applications. Note: for some makes or models of vehicles, the cigarette lighter port may not operate when the ignition is turned off. In such cases, please connect the solar battery charger maintainer to the battery directly.

This solar panel is not to be left out in the rain page 2 toward the bottom

My car has a high draw on the battery when sitting. This keeps the battery full all the time.

I bought this to maintain my personal truck battery during the week while I used the company truck. I had a 5-watt charger that wasn’t cutting it during the colder weeks. I figured a 10-watt would be better. After the first week I used it (and it wasn’t that cold) the truck had to be jump started. It was a sunny day and I checked it with volt meter and it read zero. Meanwhile my old 5-watt one was reading 11-13 volts. I’m going to exchange this for another, but if it has the same problem…

The 10W Solar Battery Charger and Maintainer is charging my battery while being hung on the inside of the window facing South. In Central Illinois during last half of December and even with a sold cloud cover it was still producing energy to charge my battery.

The solar charging package arrived in excellent condition and earlier than expected. It was easy to install and appears to be working correctly.

I picked this up for our camper I love the option for mounting to the battery I’ll be using this for my truck as well. I wish the suction cups would work on both side the charge controller won’t let the suction cups work as they are not long enough. Other wise great product

Seems good, but there is no indication that anything is happening.
Maybe have some indication when there is a connection to the battery and/or if the panel is charging the battery.
I will second the other review, longer cables would be nice too.
Tom –
Almost perfect, however longer cables would have made the product much better.

It seems to be working well. However it should come with some documentation. Because it is MPPT, there is no way to test it other than to see if it’s charging your battery. With other solar trickle chargers, you can measure the open circuit voltage and the short circuit current. With this panel you can’t. Some documentation included could avoid a lot of confusion.
