How to Use the Battery Adapter for Makita 18V Battery?

The usb adapter for Makita 18V battery has no power switch. Will it keep draining the battery if left connected?

No. The adapter enters sleep mode after 30 minutes with no output and automatically reactivates when a device is connected, helping prevent unnecessary battery drain.
How bright is the built-in LED light?

The built-in LED has a 2W output and is designed for emergency and backup lighting only. It provides basic illumination in low-light situations but is not intended as a primary work light.
Why isn’t the LED button designed to be more raised or prominent?

A less prominent button helps prevent accidental activation when the adapter is stored in a toolbox or backpack, avoiding unnecessary battery drain. During use, the button can be pressed with a fingertip.
Why don’t the USB ports always output maximum power?

Fast charging requires protocol support from the connected device and cable. USB-C uses PD 3.0, and USB-A requires a 12V fast-charging protocol. If unsupported, output defaults to 5V/3A for safety.
How can I charge the Makita battery using this battery usb adapter?

Connect a USB-C wall charger to the USB-C port, and the adapter will charge the battery. This feature is intended for emergency or backup charging, offering added convenience when a standard charger is not available.
