Nowadays, the batteries used inside portable energy storage batteries are usually lithium-ion battery packs. The lithium-ion battery packs from different manufacturers may still vary, but in general, lithium-ion battery packs have characteristics such as high energy density, long cycle life, high rate discharge, more battery capacity, richer interfaces, convenient portability, support for simultaneously charging multiple digital devices, support for multiple charging methods, short charging time and long battery life. The overall appearance of portable energy storage power supplies is designed to have good adaptability in harsh and ever-changing outdoor environments. Some portable energy storage power supplies have a small backpack appearance, while others have a suitcase like design for a trolley case. These exterior designs can make it more convenient for users to use, carry, and transport outdoors. The external design of portable energy storage power supplies not only includes external shapes, but also external materials. Although the external materials are usually purchased, after purchasing high-strength engineering plastics, they still need to be processed. Enable external materials to be processed into the desired shape and processed during the processing, making them more resistant to falls, earthquakes, fire, and rain. |
