The AUKEY PA-Y7 USB Type-C Wall Charger enables fast charging using USB Power Delivery technology over its USB Type-C port up to 29W. Let's see how this external charger powers the USB Power Delivery enabled LG gram Touch 15" Laptop (2016) with its battery being well charged.
The USB Power Delivery negotiations start off with the AUKEY PA-Y7 USB Type-C Wall Charger declaring its source capabilities of 15 watts (5 volts @ 3 amps), 27 watts (9 volts @ 3 amps), and 29 watts (14.5 volts @ 2 amps). The LG gram Touch 15" Laptop (2016) then requests to pull only 0.5 watts (5 volts @ 0.1 amps) which the charger accepts.
