The 40W USB-C® 2-Port Charger can simultaneously charge two USB-C® devices. Both the USB-C® ports support Power Delivery 3.0 and provide power up to 20W each, enabling tablets, mobile devices and handheld game consoles to charge at the fastest rates possible at the same time. For the safety of your gadgets, the charger also has surge, overcharging, overcurrent, and overheating protection. It works excellent as replacements for the original chargers that comes with a variety of mobile devices, and of course reduces the weight of your luggage especially when travelling and acts as 2 chargers in 1 to reduce the number of chargers to carry.
