I love my minty boost. It's powered my Garmin Edge 305 Bike GPS flawlessly on many a double century bike ride.
I'm getting a Garmin 500. I hear that the minty boost will charge it, but not actually power it while in use (unlike how it does on my 305)
There is another pricy device that has a switch on it to either power or charge the Garmin 500.
I'm wondering if there is a special cable or some component magic that will let my Minty Boost power my Garmin 500 and not merely charge it.
In any event, I love the product. It's preformed perfectly for years.
