Charging a new MacBook

[TEBnewyork]

A couple of the reviews showed the MacBook attached to an external battery for charging (or at least slowing the drawdown). I use the Anker charger for iPad, iPhone, Kindle, headphones etc. trying to figure out if I can just plug a USB -> usb-c cable into the same charger for my MacBook

Any thoughts?

I have this one

But they now have this one

Well they both only provide 2.4 amps per port which is 12 watts. I don't think that will power the laptop but it remains to be seen whether it will charge it when off.

Maybe it is enough to keep it alive?

Probably not. In another thread the someone noticed the rMB charger voltage was 14v at 29 Watts. A normal USB charger is 5.7 volts, so unless this poster was wrong (I tried to confirm it on the Apple site) expect other after market charger models to come out in the near future.

That may have been me. Here is the source.

I wouldn't throw the dice on using a Chromebook Pixel charger, especially if it is rated at a higher amperage. Edit: Looked it up for myself. The Chromebook power supply has three output modes: 5VDC @ 3A (15W), 12VDC @ 3A(36W), and 20VDC @ 3A (60W).

It might work, and it might fry the charging circuit. Who wants to be the guinea pig?

On the flip side, the iPad charger, at ~5VDC @ 2 Amps, might trickle charge the rMP, but it won't keep the rMP powered on.

12 W is enough to charge and power the MacBook.

It has a 39.7 Watt-hour battery. That means, if it lasts 10 hours, that's about 4W on average.
