We recommend charging the internal battery for a minimum of 8 hours before first use. Your RockSTAR can be charged from any USB compatible charging device, although the provided charger should be used whenever possible.


USB Charger output power

The USB charger supplied with your tracker is capable of outputting 2100mA. While the tracker does not require all of this, it's worth noting that USB ports on your computer and on some other mains adapters may not output sufficient power to charge properly.


To charge the RockSTAR:

  • Connect the charger to a wall outlet
  • Attach the USB cable to the charger
  • Unscrew the cap from the bottom to reveal the USB port
  • Plug the USB cable into the USB port on the bottom of the device

When charging, the LED on the front of the RockSTAR's keypad will flash red.


Charging the RockSTAR



If left plugged in, the battery will automatically cycle between around 90% and 100%. This is done to protect the health of the Lithium Ion battery inside, and maintain the device's battery life.

The estimated time to fully charge the device is 7 to 8 hours. The device can be used whilst charging, however, the charging cycle will complete faster if the device is deactivated.

The device can be used with a partially charged battery. When your device is ready for use, you can turn it on by pressing and holding the OK button for 5 seconds.
