The MicroUSB to USB Charging Data Cable provides the ability to connect your SAMSUNG phone to your computer allowing your SAMSUNG phone to become an external modem (Consult your mobile carrier for data service availability).
Multiple Charging option
A great companion to Samsung Spare Battery Charging Systems, this extension allows you to charge two micro USB compatible devices, such as phones, spare battery chargers, Bluetooth devices, etc, simultaneously. Eliminate the need to carry two chargers with the Y Cable. The cable affixes to the end of any micro USB wall or vehicle charger (sold separately), allowing you to charge two devices on just one outlet. The accessory can easily be stowed away in a briefcase or purse for use on the go.
