Most devices now have low and high charge rates. For instance, the phone can pull more amperage than your PC USB port can provide. So, it will use a safer charging profile. However, when using an OEM (or properly designed third party charger), there's a small amount of resistance across two pins that tell the phone it's safe to charger at a much higher rate. It wont matter how much amperage your charger has if it doesn't tell the phone (or the cable doesn't provide) the spec needed to change to high charge rate. At <500mAh, it's just not enough to charge and navigate (screen on, scrolling, routing, data for maps and GPS).
