With the release of the Apple 35W charger, more and more multi-port chargers are on the market.
As we mentioned, some third-party chargers have a "reconnection" issue.
But have you ever considered what would happen if we didn't remove
the cable from multi-port charger?
Today, we will answer this question.
We picked up six multi-port chargers, including power strips with USB ports and GaN chargers.
We've also prepared the USB-A to USB-C,
USB-A to Lightning, USB-C to Lightning, and dual USB-C cable.
First, let's test this power strip, which has two USB-C ports and supports up to 65W charging.
Use the dual USB-C cable to charge the MacBook and connect it to another USB-A to USB-C cable.
Nothing happened.
Replace with a USB-A to Lightning cable. Nothing happened.
Add another USB-A to Lightning cable. Nothing happened.
And replace with two USB-A to USB-C cables. Nothing happened.
Then, add another dual USB-C cable. Nothing happened.
And finally, use the USB-C to Lightning cable to test.
The tester will reboot. And the charging power will drop to 44W.
Next, let's do the second test.
Use the USB-A to USB-C to charge an Android phone.
And then, add another USB-A to USB-C cable. Nothing happened.
And replace with USB-A to Lightning cable. The tester will reboot again.
And the power will gradually go back to normal.
Let's switch to a 100W multi-port GaN charger for the third test.
And firstly, charge it with dual USB-C cable.
Then pay attention to what happens when we plug in different charging cables.
Again, the tester will reboot, and the power will drop to 44W
after connecting to the USB-C to Lightning cable.
The charger recognizes it as a charging device, even if the other side is not connected to anything.
Next, let's start the fourth test.
This is a 65W multi-port GaN charger.
Use the dual USB-C cable to charge the MacBook.
Firstly, add the USB-A to USB-C cable. Nothing happened.
And then, replace it with a USB-A to Lightning cable.
Nothing happened.
Next, let's do the fifth test.
This 65W charger has two USB-C ports and a USB-A port.
Use one of the USB-C ports to charge the MacBook.
And repeat our tests.
After connecting to USB-C to Lightning cable.
The tester also reboots, and the power drops to 20W,
which is also affected by the USB-C to Lightning cable.
Finally, Let's test with a 30W power strip with USB.
And then, add a USB-A to USB-C cable. Nothing happened.
But after connecting to the USB-A to Lightning cable.
The power will drop to 15W.
Add another USB-A to Lightning cable.
Same thing.
Now, you can understand that neither the USB-A to USB-C cable nor dual
USB-C cable will affect the charging speed.
But Apple USB-A to Lightning and USB-C to Lightning cables are different.
Almost all multi-port chargers recognize the USB-C
to Lightning cable as a charging device and affect other ports.
Some chargers also recognize the USB-A to Lightning cable as a charging device.
Because the built-in C94 and C48 chips still consume power even when not used.
So, please remember to remove Apple Lightning cable from the charger
after charging your devices.
