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.

Christo613 If your primary issue with your current setup is battery life, this will work. I've been using a phone + charger/battery bank for bicycle and motorcycle trips for the past 15+ years. The biggest issue with a setup like this is rain; if water gets into your phones charging port, the phone won't charge.
