The total output of the 45W charger ensures that you can charge your MacBook Air, iPad, or other laptops and tablets that support this charging. The 45W power is not shared. This means you can actually draw a full 45W from one USB-C port, rather than just the sum of all ports. The charger has a total of two ports: 1x USB-C and 1x USB-A. Tactical Microgrid is a master of versatility. It supports a wide range of fast charging standards, from PPS to PD3.0, QC3.0, Samsung, AFC, Huawei, BC1.2, and Apple.
