         1.Core Function – Portable Charging

• On-the-Go Power: Its primary function is to charge your electronic devices anywhere and anytime, freeing you from the constraint of power outlets.

• Wide Compatibility: It is compatible with a vast range of devices, including smartphones, iPhones, Android phones, tablets, Bluetooth headphones, smartwatches, fitness trackers, digital cameras, and even some small laptops.

• 2. Capacity & Power

  • Capacity (mAh): The capacity, measured in milliamp-hours (mAh), determines how many full charges it can provide. For example, a 10,000mAh power bank can fully charge an average smartphone 2-3 times.

  • Output Power (W/A): The output current (A) and power (W) determine charging speed. Many modern power banks support Fast Charging and USB Power Delivery (PD) for compatible devices, significantly reducing charging time.

  3. Ports & Connectivity

  • Multiple Output Ports: Most power banks come with two or more USB-A and/or USB-C ports, allowing you to charge multiple devices simultaneously.

  • Dual Function Ports (USB-C): A USB-C port can often be used for both input (charging the power bank itself) and output (charging your devices).
