5. Power 

Sources 

 

There are three ways to power the ALVA BC640: 
 

 

Using the USB power (Base Unit only); 

 

Using the internal battery; 

 

Using the external power adapter 

 
In the subsequent sections, you will find more information about each power option. 
 

5.1. USB 

power 

If you connect your ALVA BC640 directly to a PC using the USB connection, the PC 
will provide power to the Braille display through the USB cable. To power the ALVA 
BC640 with Braille Audio Feature Pack, please use the power supply that came with 
the unit. Please note that only the ALVA BC640 Base Unit can be powered via the 
USB connection. The USB connection provides sufficient power to charge the base 
unit’s internal battery and to operate the ALVA Braille Controller Base Unit. 
 

5.2. Internal 

battery 

 

The ALVA BC640 runs on an internal battery in case no external power is attached or 
no USB connection is used. The ALVA BC640 will approximately run 12 hours on a 
fully charged battery. Typically, the internal battery is used in case of a wireless 
Bluetooth® connection. 
 

5.3.  External power adapter 

An external power adapter is provided with the ALVA BC640 package. As soon as 
the external power adapter is connected to the Braille Controller, the battery will be 
charged and the ALVA BC640 will draws its power from this adapter. Please note 
that the ALVA BC640 with Braille Audio Feature Pack cannot be charged via the USB 
connection. Charging an empty battery will take approximately 4 hours. The external 
power can be used in combination with wireless Bluetooth® technology or the USB 
connection.  

 
Warning! Do not use another external power adapter than the one supplied in 
the ALVA BC640 package.
