Introduction: USB Macbook Charger

Picture of USB Macbook Charger

As i am traveling a lot for work and also volunteering in Africa i was looking for a device so i could use my macbook in remote areas without electricity.

As the only battery i carry with me on those trips is my powerbank, it would be ideal to use it also to give some power to my laptop.

Another point i also wanted is keeping the macbook charged on the airplane, and on most planes you have only a USB port at your disposition.

Step 1: BOM

now great idea but you have to work little more by building a power bank with more power and capacity

I once built a similar setup with the Xiaomi Powerbank. But it
delivers maximum 2.5A, which makes 10-13W. My MBA needs in average
10-20W, so the output power of the Xiaomi Powerbank was never
sufficient. What's your experience?
