Try this from Amazon. Make sure that you choose the USB-C one and not the QC 2.0 versions.
I left verizon in november, couldnt be happier. service with verizon was a bit better, but wifi is fine where service is bad.
I had no problems
I also like to have a fuck ton of charging options everywhere I go, rather than keep one with me all the time. you could do the adapter route that you linked to, just know you will be limited to 1.5 amps no matter what amp charger you use, its by design of the 6p. for usb c cables, chargers and misc, look at this spreadsheet https://docs.google.com/spreadsheets/d/1wJwqv3rTNmORXz-XJsQaXK1dl8I91V4-eP_sfNVNzbA/edit#gid=0&vpid=A2

I got this Choetech charger/cable combo from Amazon. I saw it recommended in a post about reliable chargers on this sub and it is working very well.
