When your HoloLens is on, the battery indicator shows the battery level in increments. When only one of the five lights is on, the battery level is below 20 percent. If the battery level is critically low and you try to turn on the device, one light will blink briefly, then go out.


To get an estimate of your current battery level, say "Hey Cortana, how much battery do I have left?"

The power supply and USB cable that come with the device are the best way to charge your HoloLens (1st gen). The power supply provides 18W of power (9V 2A).

Charging rate and speed may vary depending on the environment in which the device is running.
