iVoler, a company that focuses on chargers and accessories for mobile devices, released their iVoler 75W USB Type C Charger with Power Delivery to support new USB Power Delivery based devices like the HP Chromebook 13 G1. Let's see how well these devices work together.
Using software from Granite River Labs, we were able to verify the existence of PD communication between the iVoler 75W USB Type C Charger with Power Delivery and the HP Chromebook 13 G1.
As we can see the iVoler 75W USB Type C Charger with Power Delivery initially declares that it supports 5, 9, and 15 volts @ 3 amps. However, later it declares a different Source Capability of 5, 9, 15, and 20 volts @ 3 amps.
Initially the HP Chromebook 13 G1 requested the first PDO (15 watts or 5V @ 3 amps), then requests the third PDO (45 watts or 15 volts @ 3 amps), and then finally requests the fourth PDO (45 watts or 20 volts @ 2.25 amps).
We see that the HP Chromebook 13 G1 draws 20 volts and roughly 1.8-2.3 amps from the iVoler 75W USB Type C Charger with Power Delivery, confirming the fourth PDO request of 20 volts @ 2.25 amps.
This charging was done with the HP Chromebook 13 G1's battery roughly at 85-90%.
It's interesting to note that with the Chromebook battery charge also at 85-90%, the Anker PowerPort+ 5 USB-C with USB Power Delivery provides less power with 15 volts @ 1-1.5 amps to the Chromebook.
