Title
Upgrading Belkin Micro Auto Charger USB to signal 1 amp charging current to HTC Hero and other devices
Introduction
The Belkin Micro Auto Charger USB F8Z445 is rated at 1 amp. However, many devices will not know there is more than 500 mA available, and only charge at a low rate. This is because the Belkin adapter does not provide a 200 ohm resistor between the -D/+D pins, which would tell the device of its higher current capability. Connecting a resistor between the data pins will convince the charging device that there is full power available, and it will charge its battery more quickly, at up to a 1 amp rate.
Steps involve opening the adapter case, soldering a 200 ohm resistor in place, and closing the case.

Summary
Upgrade the Belkin "Micro Auto Charger" USB power adapter to signal USB devices that the adapter is capable of its rated 1 amp power output. On an HTC Hero and similar device, this will show as "Charging (AC)" instead of the slower "Charging (USB)".
