#1

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

i realize this after a period of time using my macbook at 100% and it goes down to 90% and it has more than 10hr of charging time until full

-But when i use the PowerPort+ and the original Apple C to C cable

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 ?

please help me . Thank you !

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.

Your best bet to get the maximum charging rate would be not to use Ankers usb c to c cable but rather their newer Anker USB-C to USB-C Thunderbolt 3.0

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).
