What is the use environment of outdoor power supply？

Outdoor power supply is mostly used in outdoor travel, emergency disaster relief, outdoor operation, medical rescue and other scenarios. In some special use scenarios, outdoor power supply also needs to have very good protection performance.

A high-quality portable power supply should have good protection performance, including testing the product quality through waterproof and dustproof, falling, vibration, high temperature, high humidity, high altitude and other experiments, but the protection performance of the plastic enclosureis weak.

The user group of outdoor power supply is relatively large and wide, which is generally concentrated in self driving tourists, outdoor operators, stall operators, and people who like outdoor activities (such as adventure, fishing enthusiasts and other activities). According to the following data, most of the users are men aged 20-39.

The power enclosures of outdoor power supplies with high monthly sales volume are scattered in size, and the battery capacity of such power supplies can meet the requirements. Most people who go out for only 1-3 days can easily put it into the trunk: most of the enclosurematerials used are plastic materials with low cost and iron plates, and the power supply enclosurewith small portable volume and large battery capacity is popular with the majority of people. Aluminum boxes and ip68 enclosure plastic are usually used for larger power supply shells, because aluminum is lighter than iron, and has strong ductility, high heat dissipation, weatherproof enclosure hinged，and is more stable than other aluminum shells when subjected to falling, rolling, extrusion and other external forces.

The capacity with high sales volume is concentrated in small 50000mAh - 100000mAh and medium-sized 200000mAh - 300000mAh.
