Your Garmin Forerunner 301 personal trainer is powered by a built-in lithium-ion battery that you need to recharge as you use your Garmin unit. An AC charger comes with the Garmin Forerunner, and you can also purchase a Garmin USB cable to use for charging your Garmin personal trainer device.

Skill level:


  1. 1

    Turn the Forerunner 301 over and pull back the weather cap covering the USB port on the back of the unit.

  2. 2

    Plug the mini USB end of the AC charger or USB data cable into the USB port on the Forerunner.

  3. 3

    Connect the other end of the cable to a wall outlet (if you are using an AC charger) or to a free USB port on a computer (if you are using a USB data cable).

  4. 4

    Leave the Forerunner charging for three hours before you begin using it or until the charge gauge displays full bars.

Tips and warnings

  • The Forerunner 301 device does not charge outside the temperature range of 0.00 to 50.0 degrees C.
  • Make sure that the USB port, weather cap and surrounding area on the Forerunner are thoroughly dry before you begin charging the device to prevent corrosion.
