How Well Motorola TurboPower 15W Charging Goes with the LG G7 ThinQ

Besides its own bundled LG 16W Qualcomm Quick Charge 3.0 Power Adapter, the LG G7 ThinQ can still get charged using certain third party chargers like the 15W Motorola TurboPower Charger that came with the Motorola Moto G6. Although the Motorola TurboPower Charger uses the Lenovo branded TurboPower quick charging scheme which is not supported by the LG G7 ThinQ, let's see how it works between the Motorola charger and the Qualcomm Quick Charge 4+ enabled LG phone. Through Qualcomm Quick Charge 4+ technology, the LG G7 ThinQ  can take advantage of USB Power Delivery 3.0, PPS (Programmable Power Supply), and Qualcomm Quick Charge 3.0 technology over USB Type-C.

Overall we observed the LG G7 ThinQ at 0% battery level to take around 140 minutes to charge fully with the Motorola TurboPower Charger. When connected to the charger's USB Type-A port, the phone initially drew power in a 0-12 watts band without a stable current at mostly around 7 volts rail. In the next hour, the voltage ramped up and down between 5 volts and 6 volts before both voltage and current leveled out for more stable charging. The current then gradually decreased for charging to drop to less than 2 watts over a duration of 2 hours and 16  minutes as the battery was almost full. 

The LG G7 ThinQ uses very aggressive power management schemes such that even while the charger is connected to the phone, the current repeatedly goes down close to zero at repeated intervals.

The LG G7 ThinQ fortunately works fine with the Motorola TurboPower Charger to achieve a similar charging duration with the phone's own LG 16W QC Charger over Qualcomm Quick Charge as seen here. In fact it does seem the TurboPower charger may very well support Qualcomm Quick Charge 3.0 technology since it charges similar to the LG 16W QC Charger.
