Most mp3 players are designed to be charged via a usb port using a device such as a computer, as well as using the supplied DC adapter. The reason why charging a mp3 player via usb works is because it can provide sufficient charging voltage of 5 volts to the battery, the same amount of volts a DC adapter can provide. If you don't have a DC adapter to use to charge your mp3 player's battery up, you have an alternative method available, which is to connect your mp3 player to your computer through the usb port and charge it that way. There are two possible ways to connect your mp3 player to a computer's usb port, either by using an usb cable or removing the protective plastic cap from the mp3 player itself to reveal the usb plug. Not only can you charge it using a computer, but anything that has usb port will work, including games consoles such as the PlayStation 2 & 3 and Xbox 360.
1) Identify how your mp3 player can be connected to a usb port. Some particular mp3 players have a usb plug built into them and some require an external usb cable to make the connection. If you are not so sure about the type of connection it uses from just looking at it, i would suggest you read the user manual for further guidance.
2) Power off your mp3 player because you don't want the battery life draining while its charging, as that will slow down charging time. If you are using an external usb cable to make the connection to your computer, attach one end of the cable into the mp3 player and the other end, which is a usb plug into a spare usb port. If your mp3 player doesn't require a cable because it as an integrated usb plug, then remove the plastic protective cap and insert it into a spare usb port. On most computers, usb ports are found on the front panel or at the back of the PC tower.
3) Once you have connected your mp3 player to your computer, power on the computer to provide voltage down to the usb port. Now your mp3 player will be charging successfully and the charging indicator will be displayed on its screen. When it is fully charged, you can switch off your computer and disconnect it from the usb port to save electricity.
