The Multimedia Dock retails for $49.00 and includes a micro USB charger. The dock is compatible with the Samsung Galaxy S3 with or without a case. More after the break.
The dock is designed for easy drop in charging and incorporates a 3.5 mm audio out port. With the compact design the dock is perfect for travel. I use the dock on my night stand to charge my S3 at night so it is ready for the day. Available here AT&T
