> Charging with normal smartphone battery packs is now possible.
I was going to rebut this statement as useless (my instincts were telling me that it should be under 10% of the total built-in battery), then I did the math. Your typical high capacity charging pack providing 15,000 mAh actually has almost double the capacity of a built in battery for the 13" MBP.
15,000 mAh * 5V / 1000 = 75 watt-hours
Compared to ~50 watt-hours for the MBP
I'll say that again. A sub $50 battery pack provides almost double the battery life of the one built into a $1,500 laptop.

It would be less, given the (dis)charging efficiency. Quick look at search results suggests about 80% (so ~60Wh), which is still nice for that price though.
