If you need portable ultra-fast charging for your most demanding devices, consider the Anker 717 USB-C 140W GaN Charger in black and silver. The Anker 717 manages to deliver a blistering 140W of power from a charger you can tuck away in a bag or backpack by using GaN technology. GaN stands for Gallium Nitride and replaces Silicon to keep the charger small and improve heat dissipation without sacrificing power output. The single USB-C PD 3.1 port can be used to recharge everything from smartphones to laptops. With 140W of power, Anker uses ActiveShield 2.0 to ensure your device is protected.
