40W USB Type-C Charger Gets Your Mobile Device Ready in a Hurry, Wherever You Are This single-port USB charger lets you quickly and safely charge your USB-C mobile device. Plug it into any NEMA 1-15R, NEMA 5-15R or NEMA 5-15/20R AC outlet to ensure your MacBook Pro, Chromebook, Windows laptop, smartphone, tablet or other USB-C device charges at its fastest possible speed. The USB-C port supports USB Power Delivery (PD) 3.0 charging up to 5V 3A (15W), 9V 3A (27W), 15V 2.6A (39W) and 20V 2A (40W). Gallium Nitride Technology Allows High-Wattage Capacity in a Compact Package This USB wall charger is smaller and lighter than most standard wall chargers that come with a laptop, measuring less than 3.5 cubic inches. Ideal for travel, it is designed using GaN technology, which has a higher power density than silicon and provides higher efficiency than standard USB-C fast chargers. It also operates under much cooler temperatures, despite its small size, meaning it won't get hot while charging your device. Built-In Auto-Sensing Adjusts to Proper Power Level to Get Your Device to 100% The USB-C port features auto-sensing technology that automatically adjusts to your device's appropriate power level, perfect for fast-charging tablets and e-readers. The unit protects against overheating, overcurrent and overcharging-in fact, it stops charging as soon as your device's batteries are at full capacity. Folding Plug Design Perfectly Sized for Travel The compact USB Type-C charger, small enough to fit in the palm of your hand, is easy to carry in your purse, suitcase, backpack or laptop bag. The NEMA 1-15P plug folds into the unit when not in use to shield it from damage and prevent it from snagging or scratching your bag's contents.
