A power bank keeps your phone, earbuds or tablet charged when you’re away from a socket. Capacity, measured in mAh, shows how many times it can charge a phone. A higher number lasts longer but is usually heavier. For faster charging, choose a model with USB-C Power Delivery (PD) and check its wattage. Also look for built-in safety protection against overheating and overcharging. Every power bank we sell is genuine, and we offer cash on delivery and fast delivery across Pakistan.
