The Motorola Moto G6 can use USB Power Delivery 2.0 over USB Type-C other than its own TurboPower charging scheme to be able to charge quickly with USB Power Delivery based chargers like the 27W Essential Fast Charger that shipped with the Essential PH-1 phone. We observed overall charging between the Moto phone and the Essential charger to take about 106 minutes to near full charge from a fully drained battery on the phone.

At first plugin with VBUS at 5 volts rail, the Moto G6 began pulling quick changing current to initially draw up to about 5.9 watts (5 volts @ 1.18 amps) from the Essential Fast Charger. The current then went down to zero prompting a hard reset which triggered the phone to speed up charging to about 16 watts (5.2 volts @ 3.1 amps). After the phone was turned on and being used, it gradually pulled lower current to charge at about 12 watts (5.2 volts @ 2.3 amps) when reaching 40 minutes of charging. The current later ramped further down to about .2 amps when the battery was almost full. Click here to download the trace captured by the GRL-A1 power analyzer to see more details.

With the Essential Fast Charger the Moto G6 was able to achieve up to 16W charging as also seen when using its own Motorola TurboPower based charger. But unlike TurboPower the Moto G6 pulled current at a steady rate, resulting in a more stable charging with the Essential Fast Charger while the phone charged using a rapid current modulation approach with the TurboPower charger (probably to reduce heat and improve battery life).
