The Essential 27W Charger Supports Interesting Charging Voltage Levels

The Essential Fast Charger is the main charger accessory that ships with the Essential PH-1 and is labeled on the outside as supporting 15 watts (5 volts @ 3 amps) and 27 watts (9 volts @ 3 amps).

However, using the USB Power Delivery Compliance C2 Tester from Granite River Labs to run just a subset of the full USB Power Delivery compliance test suite, we can see that this charger actually supports four PDO's for charging: 15 watts (5 volts @ 3 amps), 18 watts (6 volts @ 3 amps), 21 watts (7 volts @ 3 amps), and 27 watts (9 volts @ 3 amps). The USB-IF specification does not require that the phone support 6 and 7 volts but we observe in a later post that the Essential PH-1 actually uses all these four voltage levels when charging from the Essential Fast Charger.
