    Does anyone know of any packs that can output enough to charge the new 2016 pros?

    Good to know. I stayed away from that product because of the line below, but if it does actually work thats great! Thanks for the input.

    When you attend a university that invests more into building giant buildings and leaves nothing in the budget for electrical outlets you begin to find yourself in a very desperate situation.

    How much power does this give your laptop? Does it come with the cable needed to charge? If not, which one do you use?

    You don't need to fully power it; you simply need to prolong its battery life to make it through the day.

    Also, have a look at iStat Menus. It can show power usage in the menu bar. That way, you can keep an eye on things.

    OK, I did a little calculation. That Anker battery pack is 20100mAh. That number says: I can output 20.1 amps per hour at 3.3V (the internal batteries' native voltage). USB uses 5V so that's 20.1 * (3.3/5) = 13.3 Ah. During the conversion, about 20% is lost, so 13.3 * 0.8 = 10.6 Ah. At 5V, that's 53Wh.

    Now, my MacBook on average uses about 15W (due to the apps I use). So 53 / 15 = 3.5 hours of extra laptop usage.

    Does it come with the correct cable?

    Does anybody know if it comes with the cable to charge the MacBook? I am buying it now!

    Seems all they state is that it comes with a 90cm USB-C to USB-C which I assume would do the job, but you could always use the cable that came with the laptop right?

    Thanks for your reply. After long research, apparently it comes with a 90cm USB-C to USB-C cable to charge (and charge only the battery itself). After somebody figured out it isn't 56KΩ, which is apparently what is recommended to charge your laptop and other devices with. Even Anker support recommended purchasing another cable to charge your devices with.

    Yup, it says on Amazon: "90cm USB-C to USB-C cable".

    Seems it is only capable to charge at 5V / 3A i.e. 15 W.

    You would preferably want something that can charge at 20V / 5A. I do not think such power banks exists today.

    i think the idea is you use the ac plug to charge the 15"mbp. The ac outlet can do up to 100w.

    From what I've seen, portable batteries top out at 5V / 3A (15W) these days. After conversion loss, that would basically cancel out the discharge rate of a 2016 MBP during light-average use, but you wouldn't really see your battery level rise unless the machine was sleeping or idle.

    According to this review:
    https://plus.google.com/102612254593917101378/posts/XNH22inUQAw?sfc=true
    it can possibly charge at more than 5V:
    "The "Split PDO" advertises even more levels than claimed on the box. It has 5v/3a 9v/3a (12v/2.4a) 15v/2.1a 20v/1.5a."

    However, the review also notes: "RavPower made a number of mistakes causing it to be "plain weird". This thing is as complicated (if not moreso) than the insides of a Chromebook laptop." It's a very long review, but what it comes down to, is: it may work on your laptop but that could change when the laptop manufacturer changes something in the USB-C Power Delivery rules. Which actually happened when Apple updated to Sierra 10.12.2.

    Thanks for the update. As I do not have any battery problems on my 15" I will probably just wait until there are more options to choose from.

    The whole USB power distribution things seems a bit immature and confusing?

    I think the Ac plug is for that then. The USB ports are for things like smartphones I think.
