The Apple MacBook (Early 2016) was originally given its own Apple 29W USB-C Power Adapter to keep the Mac charged, but let's see how well it supports charging with an external 65 watts based Energear 65W PD Charger using USB Power Delivery technology over USB Type-C.

Here we use the USB certified USB Type-C to Type-C charging cable that came with the Energear 65W PD Charger to connect between the Mac and the Energear charger. When observed through Granite River Labs GRL-USB-PD-A1 analyzer software, USB Power Delivery protocol transactions start off with a first couple Vendor Defined Messages to result in the Energear charger offering 15 watts (5 volts @ 3 amps), 27 watts (9 volts @ 3 amps), 36 watts (12 volts @ 3 amps), 45 watts (15 volts @ 3 amps), and 65 watts (20 volts @ 3.25 amps) to the 60% charged Apple MacBook (Early 2016).

When the Mac selects 30 watts (20 volts @ 1.5 amps) for charging, the Energear charger subsequently accepts.

Here we can see after 20 seconds from initial plugin, charging happens at around 29.9 watts (20.17 volts @ 1.48 amps), starting with a gradual increase in current pulled by the Mac when 60% charged and turned on.  

It's great that you can use a third party non Apple power source like the Energear 65W PD Charger other than the Apple 29W USB-C Power Adapter to effectively charge your Apple MacBook (Early 2016), to serve well as a travel friendly charging option for the Mac.
