High-Speed Charging for your mobile devices! Designed with 65W Power Delivery to fast-charge a MacBook or split the power to charge one device at 45W and a second at 18W. Most chargers today use silicon transistors to transmit power. Gallium nitride (or GaN) is different. It transfers more power--faster--using less energy. By reducing heat, GaN lets critical components work closer together, creating a smaller, safer product that lasts longer. Additionally, every product includes a recycled plastic bag so you can responsibly recycle your old tech for free, helping close the loop on electronic waste.
