Please do not recommend the Griffin product for the MacBook Pro. It is not rated for 87W.

Shouldn't it negotiate with the Source using its Cable Identifier and simply provide 60W (20V @ 3A) maximum to the MBP? So a slow charge, but not dangerous?

Has anyone tested this scenario in real life? I'd imagine that if the machine is idle, 60W would at least provide break-even, and in sleep, should be able to charge it. But that's assuming that the identity negotiation works properly with this hardware combination.

I haven't calculated it, but I don't see that laptop consume more than 60W.

Unless you've got all CPU and GPU cores blazing, and one or more devices quick-charging. And then it'll temporarily dip into the battery.

I wasnt trying to recommend a specific product, which is why i linked to the search rather than a specific product page.

I havent used any of them so wouldnt feel comfortable recommending any individual model

What I really want is a dongle that lets me use my existing magsafe bricks with the new MBP. Is there one of those coming?

There's a cheap Chinese one on Amazon but apparently it doesn't work properly https://www.amazon.com/HIOTECH-MagSafe-Adapter-Converter-Con...

Sounds exactly like something I want to plug into my brand new up-to-$4K laptop...

The other guys managed to design one with a < 3mm profile. It should be possible, shouldn't it?

The big problem would be with the voltage. But it looks like the USB-3.1 spec supports 20 volts (same as the 85W brick that comes with high end MBPs), and the mac power bricks only send 3-7V until they've had a handshake with the computer.

So it seems at least within the realm of physics that you could make a dongle about the size of the old magsafe-1 to magsafe-2 adapter...

Wow, that's cool. There are apparently ones for micro USB, which means that ... I can have a magsafe adapter for my phone. I might have to buy one, as my kids destroyed the last charger they tried to unplug from my phone.

Now they just need to get USB-C on the next iPhone, and everyone will complain that Lightning was fine. They should have done USB-C from the beginning for lightning, but it wasn't ready yet (and still really isn't in terms of ecosystem and standardization in practice).

> USB-C on the next iPhone

Not gonna happen, iOS devices are Apple devices.

The best you can hope for is a short 1st party lightning to USB-C female, but this probably won't happen for a while as USB-C spec requires ANYTHING with a receptacle to talk to the thing on the other end.

USBc was a response to lighting, so that would be difficult.

While I haven't tried it yet, as far as I can tell the USB-C connectors have a lot less friction than other connectors, so maybe magsafe is just simply less necessary now?

Less friction?
