Ah, the joys of USB charging protocols. It’s taken nearly 20yrs and they still haven’t got a reliable, performant solution. USB-pd gets it nearly correct, but it’s still not perfect.
Slow charging speeds are also very much caused by the cable type. Back when I was charging micro-usb based smartphones I went through a handful of cables and anything that negotiated at <2a went in the bin. There really is a lot of junk out there. A USB power meter and a qc3 compatible charger is a good starting point. On Wed, 3 May 2023 at 18:19, Peter Merchant <petermerch...@hotmail.com> wrote: > > >> I didn't make last night.
