How to charge SmartHalo?


SmartHalo is meant to stay on your bike as long as possible, so that you do not have to actively think about charging it every day. This is why we made sure the battery life would last as long as possible. Under normal usage, the battery should last 3 weeks between charges. 

To charge SmartHalo, take it off from the mounting base using your HaloKey™, open the rubber flap and use the provided USB cable to charge it from a computer or a wall charger. 

Some users have reported trouble with some chargers (notably from Apple), so we recommend trying to plug the USB cable in a computer port for consistent results. 

When SmartHalo is charging, you can tap on the surface to see charging progress. When the circle is full, the charge is complete – this should take about 4 hours. 

Some computers output less power when they are in standby. It might take longer in that case. 

Is my SmartHalo charging? 

SmartHalo indicates the battery level by a circle that fills from red-to-green.  One red dot indicates that the battery is at 0% and a full red-to-green circle indicates that the battery is at 100%.

Plugging in SmartHalo will show the charge level. When connected to your SmartHalo, you can also see the battery level in the right drawer of your SmartHalo App.

If you're unable to determine if your SmartHalo is charging correctly, please email us at with the serial number of your SmartHalo and we'll give you a hand!
