Exquisite camping fever, this year is really hot!
Going to the park on weekends, I feel embarrassed to post on social media without setting up a tent and hanging a canopy.
If you want to camp well, you can't miss products such as a canopy, tent, folding stool, cutlery, and outdoor charging. Driven by the camping craze, these peripheral products continue to heat up. According to incomplete statistics, from April 20th to May 4th this year, the sales of outdoor coffee pots, tables, chairs, and barbecue trays on Tmall increased by more than three times year-on-year, becoming the best "camping companion". The sales of outdoor power supplies (also known as portable energy storage boxes) increased by more than two times year-on-year!
Among these camping equipment, outdoor power plays a crucial role in the normal use of the entire camping scene. It is reported that portable energy storage accounts for about 10% of the total category sales of some outdoor equipment, and accounts for 60% to 70% of functional products, and its proportion is still constantly infiltrating.
It is understood that portable energy storage is a built-in lithium-ion battery that can store electricity and provide a stable AC/DC voltage output power system. It has the characteristics of high capacity, high power, safety and portability, and its battery capacity is generally between 100Wh and 2000Wh.

Portable energy storage is equipped with various interfaces such as AC input, DC input, AC output, USB/Type-C output, etc., suitable for outdoor travel, outdoor operations, emergency relief, medical rescue, and other scenarios.
The main modules of the portable energy storage system include battery cells, control systems, and thermal management. Its core technology is cylindrical battery cells and inverter technology. Currently, the main suppliers of portable energy storage batteries include Ningde, Bike, LG, Penghui Energy, etc., and the main suppliers of inverters include Tuoban Co., Ltd.
In addition to these core modules, polymer materials, due to their heat resistance, flame retardancy, heat dissipation, insulation and other characteristics, are indispensable for the shell, internal heat dissipation, and protective structure of portable energy storage.
From the perspective of the shell, due to the large power consumption of portable energy storage, the heat generation is relatively high. For safety reasons, fire prevention and heat dissipation must be taken seriously. Therefore, currently, most portable energy storage shells mainly use PC+ABC combinations with a flame retardant level of V0.
Why use a material combination of Pc+ABS? Originally, PC was made of polycarbonate, a strong and tough thermoplastic resin. It has characteristics such as high strength, tensile resistance, and high temperature resistance. It has good insulation properties and is a good insulation material, which is currently used in the shells of many safety regulated power adapters. The full name of ABS is acrylonitrile butadiene styrene copolymer, which is characterized by low strength, good toughness, low temperature resistance, easy processing, good flowability, and is conducive to coloring and spraying.
PC+ABS plastic combines the advantages of both PC and ABS materials, and the products made of it have a smoother surface and good strength. Compared with pure ABS plastic, it is more resistant to high temperatures and has better overall performance.
