Up To 3x Faster Charging: GaN Fast Charging Technology allows for up to 3x faster charging over conventional charging methods. GaN Technology: Enjoy fast and efficient charging with USB Power Delivery and GaN technologies. Along with up to 3x faster charging for USB C enabled devices, GaN technology also boasts improved efficiency and lower operating temperatures, all in a compact form factor. Ultra-Compact Form Factor: Thanks to GaN technology, this charger measures only 1.9' x 1.1' x 1.9'. Gallium Nitride (GaN) semiconductors require fewer supporting components than Silicon (Si) semiconductors, which means that a GaN charger can be much smaller than a similarly rated Si charger. The folding plug makes this the ideal USB charger for taking with you on the go. 40W Total Power: Rapidly charge any compatible device that supports USB Type C Power Delivery (PD). Power your iPhone**, iPad Pro, Galaxy S and other Android phones* and tablets, or any other USB C enabled device. *Rapid charging
