Outdoor power supply refers to portable power supply equipment used in outdoor environments, which can supply power for mobile phones, tablet computers, cameras, lighting and other equipment. The outdoor power supply has the advantages of light and portable, high efficiency and stability, rechargeable, intelligent management, etc., and has become a must-have for outdoor enthusiasts and tourists. This article will introduce the classification, performance and usage precautions of outdoor power supplies.

一. Classification of outdoor power supplies

According to different shapes and manufacturing materials, portable power station can be divided into different types such as silica gel batteries, lithium-ion batteries, and solar rechargeable batteries. Among them, silicone batteries and lithium-ion batteries are the two most common. Silicone batteries are generally composed of silica gel, lithium battery cells, PCB protection boards, etc. It is light, waterproof, and drop-resistant, and is suitable for use in complex environments such as mountains and forests.

Lithium-ion battery cells are usually composed of cobalt or iron-lithium phosphate. It adopts more mature integrated smart chip technology, which can provide stable and efficient charging services for various electronic devices, and has the advantages of short charging time, light weight and long life. Long and other advantages.

二. Performance of outdoor power supply

1. Power: the amount of energy stored in the battery, usually in milliampere-hours (mAh) or watt-hours (Wh). The greater the power, the longer the device can be powered.

2. Output power: the product of output current and voltage, in watts (W). The greater the output power, the faster the charging speed.

3. Weight and volume: The portability of the outdoor power supply is very important, and it will not increase the extra burden when carrying it in use, but at the same time, the size of the stored energy must also be taken into account.

4. Security: The more advanced the built-in circuit board management and brand protection technology, the more secure it is, and the more it can guarantee the safe use of equipment and users.

5. Charging method: In addition to conventional USB power charging, whether there are wireless charging, solar charging, car or motorcycle charging, etc., are also factors that need to be considered when choosing an outdoor power supply.

三. Precautions for outdoor power supply

1. Before use, you need to read the instruction manual carefully to avoid danger caused by improper operation.

2. During use, avoid damp, high temperature, high pressure and other damaging environments.

3. Do not throw the battery directly into the fire to avoid danger.

4. When not in use for a long time, it needs to be stored in a dry and ventilated place to avoid battery aging and damage.

5. In daily use, pay attention to carrying the charging cable and avoid being crushed by heavy objects, avoiding battery short circuit and vibration damage.

In short, outdoor power supply is a convenient or necessary power supply for going out. With the continuous advancement of technology, the power and volume of batteries have been improved to a greater extent, making it more convenient to use. At the same time, the materials of outdoor power supplies are also changing. With the introduction of new materials and environmental protection concepts, it has become more and more environmentally friendly and energy-saving, and has made positive contributions to the travel activities of modern people and the cause of energy conservation and environmental protection.
