Hi, The problem is in the charger. You check voltage - 5V - OK. But this is not enough. I don't know what is your cell phone but you need min. DC - 0,6A. For this reason search car-charger for iPhone or for iPad. The iPad needs 2,0A for correct charging. And this charger you can use for smaller (with small consumption) cell phone. Regards.
