Aside from losing magsafe this is my perfect Mac.

The other day two MBPs were running out of battery during a meeting. We plugged one into the room charger and plugged the second one out of another USB-C port on the first one.

I miss MagSafe, but USB-C is seriously cool.

USB-C is cool but there's no reason they couldn't make a MagSafe USB-C port.

3rd party companies make these[0]. It's a little plug into the USB-C port, then a break away cable.

My only complaint about the usb-c is that they're on the same side. I've gotten used to flipping back and forth on my mbp for plugging it in. (different setup at home and work)

I had that same cable before and ended up going back to the normal usb c cable for charging my Pixel.

It worked, but it seemed to take 2x - 3x longer to charge using that cable than a normal USB C cable.

I never tried it on anything else though, so I'm not sure if I had a bad cable or not. It worked, it just charged very slowly compared to normal cables.

39 buck. kind of too expensive for what it is.

Seems kinda hard to design for a port that is significantly deeper than MagSafe was.

Wait... you can charge a MBP with another MBP?

Absolutely. I still lament the retirement of magsafe, but USB-C is a considerably better standard than USB-A.

I dont know if that works, but a difficulty of USB-C has been the power profiles and who charges what and when.

It’s weird, and I would think the potential would have to be way different between the two laptops but according to the spec it can work.

You can charge MacBooks from each other.

* First laptop you plug one end of USB C cable in will the the charger;

* Second laptop will be the one getting charged.

Infinite energy.

You’d have to plug them in at exactly the same time though.

Not only that. At some point I disconnected mine from the room charger and the second one almost drained my battery. My laptop charged my colleague's

Would they at one point reach equilibrium though?

I confess I was a bit upset mine got bled dry. It should defend itself better.

Only missing the usb-c port on either sides.

This was probably done to only require a single Thunderbolt controller.

You can't run a ribbon wire to the other side?

Or even traces on the motherboard, if the thickness of the ribbon cable is an issue

For Thunderbolt? It would probably introduce too much of a delay.

It’s basically identical to the 13” MacBook Pro without TouchBar that’s been around for 2 years.

You haven't used the new macbook keyboard have you? Stay far far away.
