Technical Specifications

Discharge / Power-Out Functionality

The integrated Type-C input/output detection interface automatically switches internal resistors to identify connected devices. The Try.SRC function prioritises external discharge when connected to a DRP device — meaning your Makita battery pack can charge your phone, tablet, or other USB-C devices on the go.
