Hello everyone, i’m here to ask for your help .
i have an Anker PowerPort + 5 USB C and an new Powerline+ USB C to USB 3.0
i have a 12" Macbook which needs 29W according to the Apple’s original wall charger
-When i use this new combo i just bought . the PowerPort+ seems to be providing only 12W , as i can check in the System Report > Power > AC Charger Information
it wll provide 30W to my macbook and the charging goes back to normal again
(picture below )
I have a lot of questions:
is the PowerPort+ only provide 12W through 4 USB A ports ?
or the new Anker USB-A to USB-C only handle 12W ?
what should i do ?
Option A : change for a new PowerPort ? that can provide enough W through USB-A port ( about 29W that my macbook needs ?)
Option B : change for a new C to C Anker cable ? can Anker C to C cable handle 30W ??
Option C : if Anker USB-A to C cable can handle 30W is true then i can replace for a new one right ?
I think that your issue comes from the ports themselves - each USB-A port is limited to about 12W, while the USB-C can deliver the full 30W. If you use an Anker USB-C to USB-C cable, you should be fine, same as the OEM cable.
You are correct, @Sam_Reed! The USB-A ports will max out at 5V 2.4A (12 watts). This is the norm for most USB chargers to comply with the common USB-A charging specs.
For the full 30 watts, you would need to use the USB-C port (and a USB-C to USB-C cable).
