Personally, I think that if you have a miniUSB connector, ANY miniUSB should work, not one that is specifically created or rated or toned down. After all, to me, that's what "standard" means.

Generally the USB standard is designed for a computer interface and supplying a small amount of power to an attached device. It was never designed to be for charging devices, after all who would buy a computer to charge a cell phone.
However, as we all know standard things get used in non-standard ways. While USB isn't designed to output more than 100 mA to a device and later modified to 500 mA many devices with USB connectors on them need more than that. In addition the standard didn't provide for charging a device and using it independently from the computer it is plugged into. However, customer needs and desires have modified the use way beyond the standard and manufacturers are going with the flow. I guess you want to pay more for an additional non-standard connector to charge your device.
