The supplied USB cable has the shield not grounded on one end to prevent ground loops.

You cn use a standard USB cable as long as the charger and the computer are not both powered from AC or a power supply that is AC powered.

Many use a charged 3S LiPoly or a 12V Pb battery to power the charger when doing firmware updates.
