I have a Satechi headphone charger which outputs 5W via USB-C. I was able to charge my iPhone 14 and 13 Pro without issues. However, my iPhone 15 Pro Max does not charge at all. There is no notification that charging is even detected. This got me thinking, can the 15 Pro Max even be charged at 5W?

This YouTuber did tested it out

That’s an interesting video. The 5w charger block got very hot compared to all the others. It seems like the 12w charger might be the medium to keeping the heat down on the phone and the charging brick.

Thank you. Perhaps there is something about my 5W output that is not compatible with the phone.

Anyone using a Nomad base station? My 15PM doesn't charge when connected to it even using the Apple cable. It's enabled for USB PD.

Hottest charger = most waste heat

Seeming the 12W charger runs cooler it may be the ideal slow charger.

But then again the 5W charger may be of an old or cheaper design that produces so much heat.

I'd prefer to go with a charger that produced the least waste heat.

Surprising that 5W took 5hr44min for 0-100% charge.
