To see how well the LG G7 ThinQ works with third party chargers other than its own shipped Qualcomm Quick Charge 3.0 charger, we connected the phone to the Ventev Wallport pd1300 Wall Charger and observed USB Power Delivery charging over USB Type-C.
With a fully discharged battery on the LG G7 ThinQ, the phone took about 135 minutes to charge completely with the Ventev Wallport pd1300 Wall Charger. The phone could be seen upon plugin to charge inconsistently up to 12.5 watts over a band of rapid changing current on a 5 volts rail. After the first hour, the current only started to settle out to around 1 amps before ramping down in the next few minutes to eventually reach below .1 amps as the battery nearly filled up.

When compared to 140 minutes that was observed between the LG G7 ThinQ and its own LG 16W QC charger over Qualcomm Quick Charge, the phone seems to charge slightly faster using USB Power Delivery with the Ventev charger. It's also interesting to see that the LG G7 ThinQ uses very aggressive power management schemes even for USB Power Delivery such that even while the charger is connected to the phone, the current repeatedly goes down close to zero at repeated intervals.
