After I purchased my first Quick Charge 2.0-compatible device, I purchased the Quick Charge 2.0 version of the Aukey car charger. The company has since updated the same exact model ($15 on Amazon), adding QC3.0 to it without changing the design.
Note: This review is part of our roundup of USB car chargers. Go there for details on how we tested this device.
Two color-coded USB ports are on the front. The green port is a standard 5V/2.4A; the orange port is QC3.0 compatible at 9V/2A. In our tests, the Galaxy S8 registered that it was fast-charging once connected, with our meter registering 9V/1.2A. Plugging an iPhone X into the car charger, regardless of port, registered 5.15V/1.4A (the same reading as our Galaxy S8 when plugged into the standard port).
One downside of this Aukey model is its size. It sticks out a good amount from the power port, and lacks any sort of light to assist you in the dark.
Bottom line: The Quick Charge 3.0 Aukey car charger isn’t perfect, but it’s a tried-and-true car charger with fast-charging speeds.
