USB (Universal Serial Bus) is an interface which has been developed for simple connection of mouse devices, keyboards, joysticks and printers with the computer. Most of these devices do not require an external power supply, because the USB port supplies up to 500mA and 5V per connection.

You can use a USB cable to connect things like your smartphone, your navigation device, your iPad or your iPod with the computer to update them, but also to recharge them. If you use the USB versions of the travel adapters or the USB chargers from SKROSS, you can also charge your USB device very simply at any mains socket.
