I get a lot of feedback from cyclists who use a Mintyboost to charge their Garmin GPS devices on long bike rides. John posted to the Make forums with a quick-release version. Its a cool hack, and very well written! Click here to read about it

“The aim of this tutorial is to explain how I modified my Garmin quick-release bike mount (for the Forerunner x05) so that it can be used as a charging cradle. This allows the GPS unit to be used on long cycles/triathlons such as double centuries, ironman where the inbuilt battery is insufficient.” – John Hale
