Charging & turning on device

Note: GPS 2 (Verizon) guidance is available here 

The Guardian device is charged with a standard USB charger. It takes about 4 hours to recharge the battery. The device automatically powers on when it is plugged in. 


To charge the battery:

  1. Connect one side of the USB charging cable to the wall charger and the small connector to the Guardian device. 
  2. Charge the device near a window with good cellular reception, so that data can be regularly transmitted to the app.
  3. Ensure that the device is charging:
    • The blue LED light on the device should be on continuously.
    • The battery in the app status bar should be green with a lightning bolt by it.

To Power on the device:

See Turning on / restarting the device



  • The device’s charging port is not under warranty.
  • We recommend that an adult connects the device to a charger, and not a child. 
  • Attach the charger gently. 
  • The bottom side of the connector has an arrow drawn on it. 
  • Connect and disconnect the cable in a straight movement without wiggling.  
  • We suggest to keep the device charging when not in use. It is best to keep the device charged instead of letting the battery run out.
