- Internal Battery and Power
Your turfRad has a small internal battery. It uses a USB to 12V adapter.

Your turfRad sensor has a small internal battery to allow the sensor to upload data after you turn off your vehicle and to keep it running for short periods when you power off the vehicle. The battery charges from your vehicle and the sensor turns itself off after 20 minutes (when the data upload and a possible software update are completed).

When using the included USB to 12V adapter, you must ensure that the USB port used is rated for 5V 2A and not 5V1A.This info is usually written on the USB port. Do not split the USB connection to power multiple sensors; you may split the 12V cigarette lighter to power multiple sensors.

The 12V cigarette lighter plug includes the locking mechanism present on many equipment receptacles. To lock the plug in place, push it in and turn it clockwise. We recommend using electrical tape to secure the 12V plug in non-locking receptacles or the provided USB adapter.
