I never understood the need for a Garmin. Just mount your smartphone on your stem and use Strava.
My setup uses a Quad Lock for the phone, with an accessory battery bar extension.
Got it on Amazon for less than twenty bucks. Both USB-A and USB-C plugs.
Never got around to buying a shorter cable. Someday will do it. lol
It keeps my phone 100% charged for five hours, with my screen full on the entire ride.
That blue-lit button allows me to turn off the charger, for whatever reason.
My attached integrated-battery headlight can likewise accept a charge or give out a charge.
Some phones are very hard to read in bright sunlight.
Even if I could see my phone in bright sun, it uses up power much faster than my GPS. For bike touring where I might not have access to an outlet for several days at a time, I want to be able to charge all my devices from a dynohub and I doubt that I could do that if I tried to use a phone instead of a GPS. Most of my tours are remote enough that I might go for over a week without access to an outlet.
