A:AnswerHello Valued customer!
The battery level can be checked by pressing the power button, the lights on the unit will illuminate to tell you where the battery level is at before and during your project.
Thank you for choosing Worx!
A:AnswerFor full compatibility use the USB-A to USB-C cable that came with the Screwdriver. My USB-C to USB-C did not work at all. Once I used the cable that was bundled in, it started charging and the battery indicator came on.
