Virtually all sports-related electronic devices are switching over to USB-C charging from Micro-USB. I'm really thankful for this change, because the USB-C interface is symmetric--unlike Micro USB, you don't need to figure out which way to plug it in, USB-C has no top/bottom orientation. If you have a recent version of a GPS or phone, it's likely that it comes with a USB-C cable rather than a USB-A. This is the quick solution to your problem! It plugs into one of the dual USB charger USB-A ports and provides interference free USB-C charging. This works perfectly with a USB-C to USB-C cable and my Garmin inReach Mini2, charges it right up in a couple of hours from the dynamo hub. Ships in various colors.
