The LG G6 phone supports both Qualcomm Quick Charge 3.0 and USB Power Delivery charging over its USB Type-C connector, so let's see how well it charges when connected to the Tronsmart's Presto Quick Charge 3.0 battery pack which supports Qualcomm Quick Charge 3.0.
With the LG G6's battery being fully drained, the charging starts off unevenly before it stabilizes with the voltage at around 5 volts and 0.5 amps but later goes up to charge at about 10 watts (5 volts @ 2 amps).
It's good to see you can use the third party Tronsmart Presto to charge the LG G6 using Qualcomm Quick Charge technology.
