You can charge Kody terminals in two ways:
Lift the flap on the left-hand side of the terminal to reveal a USB-C port. Simply plug the included power adapter into the terminal and it will start to charge.
If you have a charging cradle, connect your terminal's power cord to the cradle, and place your terminal on top of the cradle.
If your terminal has been left uncharged for weeks and the battery is flat, it may take up to ten minutes to charge enough for powering on.
