15W Solar Car Battery Charger Kit with Dual USB Adapter

Product Overview

This 15W solar car battery charger kit combines a semi-flexible 18V panel with battery clips, a DC splitter and a dual USB car adapter. Its 435 × 197mm panel weighs approximately 240g, making it practical to carry between parked-vehicle and outdoor charging setups.

The panel uses polycrystalline cells with approximately 18.5% conversion efficiency. Battery and USB connections use separate accessories: the dual USB adapter provides regulated 5V output, while the panel supplies the 18V charging circuit.

Compatibility & Notes

For a 12V battery installation, match the panel to the battery chemistry and its charging requirements. Use a suitable charge controller where required; reverse-current protection does not replace charge regulation or overcharge protection. A controller and battery are not included.

Check polarity before attaching clips. Vehicle power sockets must support the intended charging direction; some sockets disconnect when the ignition is off. Position the panel securely without obstructing vehicle controls or visibility, and keep connectors dry. Solar current varies with sunlight and shading.
