Step 1- plug your USB power adapter that is at least 5V into the outlet
Step 2 - look at the back of your KoreTrak for the side that has “USB with a down arrow” (and then do like a red arrow that points to it)
Step 4 - identify the 2 USB-A contact points on your device to the contact points of your USB power adaptor (gif of when i was pointing at the 2 usb-a contact points and then pointing to the USB power adapt)
Step 5- plug it into the USB power adaptor *you will hear vibration and the battery button on the top right corner moving which means that connection has been made between contact points and your KoreTrak is charging
