Motorola phones have been known to support Qualcomm Quick Charge technology through its own brand of TurboPower quick charging scheme. As such the Motorola Moto G6 is expected to work fine over Qualcomm Quick Charge with the LG 16W Qualcomm Quick Charge 3.0 Power Adapter that was originally shipped with the LG G7 ThinQ. The LG charger uses Qualcomm Quick Charge 3.0 technology to provide 16 watts based charging using 7.5 watts (5 volts @ 1.5 amps) and 16.2 watts (9 volts @ 1.8 amps) power profiles.
Starting from a fully discharged battery on the Motorola Moto G6, we plugged in to the LG 16W Qualcomm Quick Charge 3.0 Power Adapter to observe charging. The phone took about 108 minutes to charge fully with the LG charger, to charge almost as fast as using its own 15W TurboPower charger in about 109 minutes as seen here.
When connected over a USB Type-A to Type-C cable, the Motorola Moto G6 started to trickle charge briefly but subsequently pulled a more stable current and voltage to charge to around 11 watts in the first hour. After the next 17 minutes, the current pulled ramped down to under .2 amps as the battery almost filled up.

It's good to see that the Motorola Moto G6 can use Qualcomm Quick Charge almost as well as its own TurboPower technology which also supports USB Power Delivery 2.0 fast charging technology over the phone's USB Type-C connector.
