You can recharge your devices much faster than standard models with Power Delivery and Quick Charge 3.0, saving hours of time in the process. It even includes a USB-A port on the opposite end, allowing you to charge two devices simultaneously, along with protection against overload, short-circuiting, and overheating.
With its purchase, a USB-A to USB-C cable is included, along with a 2-year warranty, although you would like a USB-C to USB-C cable to use the PD and QC 3.0 technology port. You will also need a way to charge the power bank, and a USB-C wall charger is the most efficient method.
