The M12 USB cable connects the laser module to any compatible power source via a USB-A connector. This can be a standard power bank, a power supply unit or the USB port of a computer. The USB standard voltage of 5 V is transformed to 12 V directly in the cable. In this way, all laser modules that require a voltage of at least 10 V can be operated.

For the user, the use of a portable USB power source means more independence from national or regional differences in mains voltage, frequency and plug type.
