The ESR PD Wall Charger is a compact device with fast charging functionality. It has two USB-C ports which work with the Power Delivery standard, so it can charge two devices at once. Experience shows that many chargers get stuck in the socket and are difficult to pull out. In light of this, the surface of the charger has a matt, wavy pattern, which makes it easy to grip when being removed from the socket. The pattern also helps people with impaired vision to be guided by their sense of touch.
