Xiaomi Rainbow Battery Packs come in different capacities, indicated in milliampere-hours (mAh). The higher the capacity, the more charge it can store and deliver to your devices. These battery packs are designed to be compact and lightweight, making them easy to carry in your bag or pocket. Many Rainbow Battery Packs offer multiple output ports, which can be used to charge different devices simultaneously. These outputs may include USB-A, USB-C, or even wireless charging options. Some Rainbow Battery Packs support fast charging technologies like Quick Charge or Power Delivery, enabling quicker charging times for compatible devices. Most battery packs feature LED indicators to display the remaining battery level, allowing you to know when it's time to recharge the battery pack itself. Certain Rainbow Battery Packs come with built-in charging cables, eliminating the need to carry extra cables with you. Some models offer wireless charging capabilities, allowing you to charge your devices without connecting them via cables. This feature enables you to charge both the battery pack and your device simultaneously when the battery pack is connected to a power source. Rainbow Battery Packs often come with overcharge, over-discharge, and short-circuit protection to ensure the safety of both the battery pack and your devices.
