This USB charger is the ideal solution for charging most of your devices with a USB connection directly through a power socket. The USB charger can handle voltages from 110 to 240 volt AC and converts them automatically to the 5 volt DC that USB devices use. You can easily charge your USB devices without the need of a PC or notebook. Almost all devices which support charging through USB, like (smart) phones, navigation systems, MP3 players and digital cameras can now be charged easily.
