iPhone 15 Pro Max Can iPhone Pro Max be charged with 5W?

[SteveJobs2.0]

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?

Charge my 15 PM every night with the 5W adapter. No issues.

Won’t hurt anything. Just takes longer.

 

[internetrando]

You certainly could. Expect it to take a long, long time.

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.

I use the Apple 5w charger to charge my 15PM every night

What’s the voltage and amperage on your charger?

Not sure, it's the 5w charging brick that came in the box of my iPhone X when I bought it from Apple..

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.

Hottest charger = most waste heat

Hottest everything — phone and charger combined = most waste heat

Anywhere that the energy is lost to heat is waste

5W can charge even a MacBook Pro if you're patient enough.

It is better than no charger at all!

Would it take 1-2 days at 5W while turned off?

It charges around 10% every two hours with the computer off.

 

[NeoSe7en]

Yes, in the same way that you can fill up a bucket by spitting in it.

That's rather quick for a MBP 16".
