40W USB TYPE-C CHARGER GETS YOUR MOBILE DEVICES READY IN A HURRY, WHEREVER YOU ARE: This dual-port USB charger lets you quickly and safely charge two USB-C mobile devices at the same time. Plug it into any NEMA 1-15R, NEMA 5-15R or NEMA 5-15/20R AC outlet to ensure your laptop, smartphone, tablet and other USB-C devices charge at their fastest possible speed. The USB-C ports support USB Power Delivery (PD) 3.0 charging up to 20W (5V 3A, 9V 2.22A, 12V 1.67A) apiece when used together. When used by itself, each USB-C port supports up to 30W (5V 3A, 9V 3A, 12V 2.5A) for charging a device.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. 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 DEVICES TO 100%: The USB-C ports feature auto-sensing technology that automatically adjusts to your device's appropriate power level. The unit protects against overheating, overcurrent and overcharging. In fact, it stops charging as soon as your device's battery is at full capacity. A blue LED indicates charge status. FOLDING PLUG DESIGN PERFECTLY SIZED FOR TRAVEL: The compact USB Type-C charger, small enough to fit in 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.
