Micro-usb car charger doesn't charge cellphone

Text:

I have an unbranded car charger (not verizon's, but similar to this http://www.wirelessemporium.com/productpics/big/verizon-micro-usb-car-charger-w-usb-port-for-motorola-razr2-v9-micrdualvpc-.jpg)

If I plug it to my cigarette lighter, the LED light turn on. However, it can't charge my cellphone. I use my USB-to-MicroUSB cable and plug it to the extra USB port, and it failed too... I use the cable everyday to charge it (plug to wall charger), so I'm sure it's not the cable problem.

I used my multimeter to test the voltage across the USB cable (red and black wire), and it registered 5V. I can't get the actual amperage because my multimeter can only go up to 250mA, and when I tested it, the reading was over the scale.

Anybody know what's wrong and hw to fix it?
