‏A portable charger, also known as a power bank, is a compact device designed to recharge electronic gadgets like smartphones, tablets, and wireless earbuds on the go. It stores electrical energy in an internal battery, which can then be used to charge devices when access to a power outlet is unavailable. Most power banks feature USB and Type-C ports for compatibility with various devices. They come in different capacities, measured in milliamp hours (mAh), determining how many times a device can be recharged. Lightweight and travel-friendly, they are essential for commuters, travelers, and outdoor enthusiasts. Some models offer fast charging and wireless charging capabilities. LED indicators often show remaining battery power. Advanced versions may include solar panels or built-in cables for convenience. A reliable portable charger ensures your devices stay powered anytime, anywhere.
