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 Apple MacBook (Early 2015). Let's see how well these devices work together.
Using Granite River Labs USB Power Delivery test software, we can see that the iVoler 75W USB Type C Charger with Power Delivery supports 15 watts (5 volts @ 3 amps) and 27 watts (9 volts @ 3 amps) and 45 watts (15 volts @ 3 amps) power profiles over the USB Type-C connector.
The Apple MacBook (Early 2015) then requests 30 watts (15 volts @ 2 amps) from the iVoler 75W USB Type C Charger with Power Delivery .
