Apple make a bold move when they introduced the new 12″ Macbook last year, that it features only one USB-C port which doubles as both data and charging port. It became the main critics in the tech community, though Apple keep going with their decision when they updated the Macbook this year, still features the single USB-C port.
However, one good thing about the USB-C port is that it is universal. Apple sell expensive adapteralong with the new Macbook, but other companies also has the freedom to offer cheaper alternatives, like this adapter from Juiced Systems. Another advantage of USB-C, together with low-power Core M processor of Macbook is that it has low power consumption and in turns, allow it to be charged from a portable battery. Enter Anker PowerCore+ 20100, one of the portable battery that tries to sell on this capability and I put it into my own test.
