Turn your laptop adapter to a car or motorcycle battery charger

In this step-by-step video tutorial, we show you how to charge a 12V battery (commonly used in cars, motorcycles, electric shutters, and more) using a simple and affordable setup: a 19V laptop charger combined with an XL4015 buck converter module.
What You’ll Learn:
1️⃣ Voltage Regulation:
The XL4015 module is used to step down the 19V output from the laptop charger to 14V, which is the optimal charging voltage for most 12V batteries.
Learn how to use the voltage adjustment screw on the module to precisely set the voltage.
2️⃣ Current Limiting:
Proper current adjustment is critical for safe battery charging.
A filament bulb is connected to the output of the module as a test load to help adjust the current using the built-in potentiometer on the module.
3️⃣ Safe and Effective Charging:
Once the voltage and current are set, connect the battery to the module's output terminals to begin charging.
This method is simple, cost-effective, and perfect for DIY enthusiasts looking to repurpose an old laptop charger.
Why This Method Works:
Laptop Charger: Provides a stable and reliable DC power source.
XL4015 Buck Converter: Efficiently steps down and controls voltage and current, ensuring the battery is charged safely.
⚠️ Safety Tips:
Always double-check the voltage and current settings before connecting the battery.
Use proper insulated connectors to avoid accidental short circuits.
Monitor the charging process to prevent overcharging or overheating.
