Sunway Solar Car Battery Trickle Charger & Maintainer – 12V Solar Panel Kit

Overview

The Sunway Solar Car Battery Trickle Charger & Maintainer is a compact, solar-powered helper designed to keep your 12V batteries ready for daily life and longer storage. The unit pairs a small four-watt solar panel with a practical, automatic charging strategy, helping offset minor battery drain from clocks, alarms, and sensors so you’re less likely to wake up to a stubbornly dead battery.

Designed with simplicity in mind, you can mount the panel on a windshield or dash and connect it to the vehicle’s 12V outlet. A built-in diode guards against reverse charging, while an LED indicator lets you confirm when charging is active. The package includes a cigarette lighter adapter and sturdy clamps for flexible installation across different setups.

How it works

Sunway Solar’s trickle charger captures ambient light to provide a steady top-off charge to 12V batteries.
