When your Saphe Drive needs to be charged, a small battery icon will appear in the upper right corner. This icon tells you that your Saphe Drive will need a charge soon.

You charge your Saphe Drive by plugging it into a USB charger. It can be from either a computer or a regular USB charger that many phones, tablets and other electrical devices use.

You can use the supplied cable to connect the traffic alarm to the USB charger, or you can use any other USB to Micro USB cable.
