Samsung Rugby A837

Does the A837 charge when it is plugged into a USB port from a computer? That is, does it draw power from the USB cable? Or does the phone have to be charged with “special” chargers that plug into the USB port on the phone? I am looking to get one of these “rugged” phones for my girlfriend, she is VERY hard on regular flip phones. Two years usage and the case is cracked and the hinge is falling apart. I just want to know if any ol’ USB outlet on a computer will charge this phone. We have lots of USB ports around, all over, that could be used to charge a phone.
