USB Note is designed to notify blind people about the charging status of various devices in case when these devices do not provide this information in an accessible form.
The USB Note will notify you when:
You can switch between notification modes by pressing the button. To do this, shortly press the square button. When pressed for the first time, the sound mode changes to the vibration mode. When pressed again — the vibration mode changes to the light mode. The change of notification modes occurs cyclically, so if you accidentally chose the mode you weren’t going to, just keep pressing the button in the manner described above.
