HoloLens 2

Unboxing your HoloLens 2

The following procedures help you set up a HoloLens 2 for the first time:

Charge your HoloLens

Connect the power supply to the charging port by using the USB-C cable (included). Plug the power supply into a power outlet. The power supply and USB-C-to-C cable that come with the device are the best way to charge your HoloLens 2. The charger supplies 18W of power (9V at 2A). With the wall charger supplied, HoloLens 2 devices can charge the battery to full in less than 65 minutes when the device is in standby.

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

  • When the device is charging, the battery indicator lights up to indicate the current level of charge. The last light fades in and out to indicate active charging.
  • When your HoloLens is on, the battery indicator displays 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 blinks briefly, then goes out.

Full details on device charging can be read here if more information is needed.

Adjust fit

Place the HoloLens 2 on your head. If you wear eyeglasses, leave them on. The brow pad should sit comfortably on your forehead and the back band should sit in the middle-back of your head.

If necessary, extend the headband by turning the adjustment wheel, and then loosen the overhead strap.
