iPhone 6(S)/Plus iPhone loads faster from Mac than from USB loader?

[Sciuriware]

Hi all,
how is it possible that my iPhone (and my Magic Mouse too) loads 3 times as fast from the USB-A ports on my iMac
than from a genuine Apple 230Volt loader using the same USB to Thunderbolt cable???
;JOOP!

When you say "loads" do you mean "charges"?

When you say "Thunderbolt" do you mean "Lightning"?

Yes & yes ...

That depends on the power output given by the wall adapter.

Really? Both are feeding from the same wall socket, which delivers enough power for my heavy vacuum cleaner.
My own assumption was, that the 230V-to-USB charger has a lower charge current, not to overheat anything.
Then again, with all those things in mind that you can connect to the Mac directly ...
... that connection should never overheat.
;JOOP!

In this case I mean the adapter where the USB cable connects. For instance, if you have a 5W power brick, you will only get 5W of power. With 5W it takes a long time to charge to full battery. However, faster charging is achieved with either a 7.5W or 20W adapter.

It seems that my charger is 20W; no idea how much an iMac will charge.
Anyway, I almost got my answer.
Thanks

if you open the system profiler on your iMac after connecting your phone, you should see something similar to this:



In the example above, the USB port offers the default 500 mA, as shown in the Current Available (mA) entry. The Current Required (mA) entry indicates the current the device needs to operate. Extra Operating Current (mA) indicates that this USB port is providing an additional 1600 mA for use with the device.

The ”genuine” power supply, you mention, will probably supply less current.

nota bene: what’s it with the German luxury fashion house specializing in contemporary clothing and cosmetics?🤓

Thanks a lot; my iMac 27' shows almost the same figures. Now everything is clear.
;JOOP!
P.S.: I do hope your N.B. was not directed to me, or you missed me ±400 Km Eastward.
