A1 is also a power bank... Didn't know this feature.

IIRC this is a "feature" on all usb C devices.

I was able to charge my friend's iPhone 6 to 90% with 15% left over on my Redmi Note 4. I don't remember what he was at before but he was pretty low IIRC. Thanks 4100mAh battery!

I think you have to plug one end in before the other to control which charges which. Try the USB in the laptop, then the phone, or the opposite if that's what you've been doing

I don't know why you're being down voted, but this was explicitly mentioned when the first USB c phones arrived.

Tried all sorts of combination that time. It was still charging my MacBook. Reversing the cable. First plugging MacBook then first plugging A1. Also using other USB C port on MacBook.

Didn't know that, thanks for the tip!

Just to be sure though, let's say I have devices A and B.

Device A plugged 1st = Device A acting as a charger

Device A plugged 1st = Device B acting as a charger

In Soviet Russia, phone charges MacBook.

It's an old meme but it checks out.

Can you select a different connection mode from the notifications?

That notification isn't even appearing.

I have a Mate 9 Pro and I get option to "Charge Only" or " Charge other device".

Apple is just a parasiteren 😂

Nintendo switch does the same thing.

You can try to change the USB configuration in the developer settings menu

Tried that. Had no effect.

There should be an option in settings on your phone to use your phone as a charger or charge 'this' device. Maybe install USB drivers for your phone on your MacBook would help?

This is still amazing

Which cable were you using?

MBP can be charged with 5V??

Slide down from the top to access your notifications, tap on the plugged in function, change to change this device and not charge the device you're plugged into.

You can use a phone as a power bank on micro-usb devices with an otg cable

My GPD Pocket does the same thing with a Macbook when both are hooked up via USB-C. Macbook immediately shows it is being charged.

If you want to actually do anything with your Mac book you need to insert a 50 dollar bill into the slot on the side. If you don’t have the slot then you need to purchase a slot adapter for 100 dollars then you can insert the 50 dollar bill to unlock the feature.
