What happens if you use the Innergie PowerGear USB-C 45 to charge the Apple MacBook (Early 2015)?

The Innergie PowerGear USB-C 45 packaging shows that it supports the various power profiles- 45 watts (20 volts @ 2.25 amps or 15 volts @ 3 amps), 36 watts (12 volts @ 3 amps), or 15 watts (5 volts @ 3 amps).  

Using software from Granite River Labs to capture the USB Power Delivery Protocol transaction, we can confirm there is USB Power Delivery negotiation occurring between the Innergie PowerGear USB-C 45 and the Apple MacBook (Early 2015).  

Initially, the Innergie PowerGear USB-C 45 first advertises that it supports 4 different PDO's (Power Data Objects): 15 watts (5 volts @ 3 amps), 36 watts (12 volts @ 3 amps), 45 watts (15 volts @ 3 amps), and 45 watts (20 volts @ 2.25 amps) over the USB Type-C connector.

The Apple MacBook (Early 2015) initially only requests 30 watts (20 volts @ 1.5 amps) of charging from the Innergie PowerGear USB-C 45.  

The Innergie PowerGear USB-C 45 later advertises it supports three different PDO's: 15 watts (5 volts @ 3 amps), 36 watts (12 volts @ 3 amps), and 45 watts (15 volts @ 3 amps) over the USB Type-C connector.

The Apple MacBook (Early 2015) then requests that 30 watts (15 volts @ 2 amps) of charging from the Innergie PowerGear USB-C 45.  

Actual current pulled by the Apple MacBook (Early 2015) from the Innergie PowerGear USB-C 45 was about to 1.8 amps with the Apple MacBook (Early 2015) being well charged. 

The Apple MacBook (Early 2015) takes around 1 hour 40 minutes to charge completely while the MacBook is in sleep mode with the Innergie PowerGear USB-C 45 power adaptor.
