[Q] Verify Charge speed topic

I would like to find out what the speed of charging of my phone is. I had an app or the Galaxy Phones that would tell me the rate.

I bought a charger from Amazon that promises that it would charge the fastest possible in my car, but I want to confirm it. Is there an app out there?

thank you
