Review: Good idea - Wife has a 99 5.9 cummins that doesnt get driven all the time. Things batteries keep dying every month so we slapped one of these things on and it helped keep them charged for a bit. I did have to break out an extra cable cause it wasn't too long but no biggie - gotta plug her in for the cold months anyhow. Easy to install and move around.
Review: Awesome for battery maintenance - Awesome for battery maintenance. Works great. I have a diesel work truck that I only use about every other week. In the winter the battery likes to be a little weak on it. This has allowed me to connect the cable (which is plenty long enough to reach from the obd port adapter to the windshield.). Its compact size means it just lives on my dashboard. The panel is waterproof so I bought one for my boat and ATV to keep the batteries charged as well.

## Features

- [Upgraded Smart Charger Controller] The smart charger controller built into the solar panel has six protection functions: over-temperature protection, prevention of reverse discharge, short circuit prevention, prevention of reverse polarity and over-charging protection. Meanwhile the built-in blocking diode plays an important role in blocking reverse current flow.
- [Real-time monitoring] The LED indicator has three display states, half lit means charging, blinking means fully charged, and off means no input or no battery connected. When fully charged, it will automatically cut off charging, effectively preventing the battery from being overcharged.
- [Stronger and More Durable]After rigorous testing, the A+ grade monocrystalline silicon wafers have a conversion efficiency of up to 23% to maintain a consistent output of 7.5W. The glass fibre surface is highly resistant to the environment, with IP64 waterproofing and UV protection.
- [Easy to Install and Use]The Outdoor Solar Battery Maintainer is simple to install and easy to use, just directly connect the solar panel to the battery with alligator clips. The solar panel is bendable to fit windscreens and has a strong hold on the 4 PVC suction cups it is equipped with. Also, it's easy to carry outdoor and restore on your car. Dimension: 9.84*8.66*0.47in, 0.05lb
- [Wide Application] The perfect charger/maintainer for any car, LiFePO₄, Lithium Ion, motorcycle, boat, tractor, ATV, farm equipment, and 12V batteries.

### ⭐⭐⭐⭐⭐ Keeps my truck battery charged!
*by V***N on December 18, 2025*

This little solar panel works wonders on my old pickup that I don't drive much. It came with a plug that goes right into the OBD2 outlet and keeps my battery from draining. I just lay the panel on the dash and plug it in. Very satisfied with the item.
