Envision Glasses can be charged with any USB-C cable. This can both be a USB to USB-C cable or a USB-C to USB-C cable. To charge the device, connect the USB-C cable with an adapter. While plugged in, the LED light next to the charging port pulses to indicate that the device is charging, but the device will also speak out the battery level.
Envision Glasses also supports fast charging. Use the cable provided in the box with an adapter that supports fast charging. Fast charging allows the device to be charged to 50% in less than 30 minutes.
What is the battery life of the Envision Glasses?
In terms of battery life, Envision consumes most of the battery when in use due to the need to have the camera active and light detection when using all features. Roughly 4 to 5 hours of active use.
We recommend shutting down Envision Glasses if you are not going to use them for the next three hours by pressing the power button for 3 seconds. If you are going to use them in the next three hours, we recommend that you simply put them in Sleep Mode.
