This article mainly starts from portable power station, and introduces the development, industry chain and market driving factors of the portable power station industry in depth.
1. Portable power station industry
① Definition of portable power station
Portable power station is a built-in high-energy-density lithium-ion battery that can provide a power system with stable AC/DC voltage output. It can be used in outdoor travel, emergency preparedness, and other scenarios.
Compared with traditional small fuel generators, portable power station has the advantages of safety, portability, environmental protection, no noise, and easy operation. It can widely replace small fuel generators and provide a better user experience.
② Portable power station application scenarios and market size
Portable power station application scenarios mainly include outdoor portable power station, portable home energy storage, and emergency portable power station for automobiles.
The scale of the global portable power station market continues to rise. The portable power station industry has a short development time and a late start but has been widely used rapidly, and the market scale is developing rapidly. From 2017 to 2021, the scale of the global portable power station market will continue to rise, rising from 120 million RMB to 11.13 billion RMB, with a compound annual growth rate of 210.3%.
The portable power station industry has a short development time and started late, but due to its green, pollution-free, safe and portable reasons, it has been widely used quickly, with a large market demand and a fast-growing market scale. It is estimated that by 2026, the portable power station market will maintain a growth trend and the market size will reach 88.23 billion RMB.
From 2018 to 2026, the market size of China's portable power station power supply is expected to rise from 370 million RMB to 73.67 billion RMB. Affected by the epidemic, consumers' leisure and entertainment habits have gradually changed, the penetration rate of outdoor activities has continued to increase, and the market for portable power station power has continued to expand. With the continuous deepening of the main downstream application market, China's portable power station power supply industry will
③ Industry trends
The current demand for portable power station mainly comes from three aspects:
● First, the number of outdoor active people in the world continues to increase. In 2021, the number of outdoor active households in the world will be about 150 million;
● Second, the electricity restriction measures that have appeared in various countries, especially South Africa has experienced a serious power supply crisis since 2022, and the United States, Japan, and China have also experienced different degrees of electricity restriction policies;
● Thirdly, the frequency of natural disasters such as earthquakes has not decreased, and they are often accompanied by unexpected situations such as power outages and power shortages, which bring the need for emergency rescue and disaster relief.
Various factors promote the rapid development of the top 10 portable power station companies. In the future, the global portable power station shipments will rise with the growth of demand. According to relevant statistics, shipments are expected to reach 1355 (outdoor) + 1155 (emergency) + 600 (other) = 31.1 million units in 2026, and the industry scale is expected to reach 88.2 billion RMB.
④ Portable power station industry issues
● Industry standard issue
Behind the increasing popularity of portable power station products is the chaotic market competition environment and the urgent need for a sound industry standard system. At present, in the field of portable power station, the relevant industry standards are still being formulated and have not yet been officially issued. There are some situations in the industry where the products of small and medium-sized manufacturers have serious safety hazards.
● Safety issue
Poor circuit board placement process and improper control of welding process cause cracks in chip capacitors, which will expand during use. In addition, the stratification of the capacitor will lead to a decrease in the withstand voltage performance of the capacitor. Two problems lead to internal breakdown and short circuit of the chip capacitor during charging, and cause the battery to catch fire.
● Power shortage issue
Portable power station can meet their emergency power needs, such as outdoor camping lighting, fans, audio, charging, cooking, etc., and power shortages for self-driving travel and mobile office.
2. Analysis of portable power station industry chain
● Upstream of portable power station industry chain
The upstream of the portable power station industry chain mainly includes batteries, energy storage converters, circuit boards, electronic components, and casings. In the upstream link, batteries, inverters and photovoltaic power generation have core technical barriers, and the supply in the Chinese market is relatively sufficient. Batteries and inverters account for more than 50% of the overall cost.
The batteries are mainly cylindrical batteries such as 18650 battery, emphasizing the number of cycles, and the light weight of the product drives the demand for large batteries. In terms of the trend of battery cells, due to the continuous evolution of terminal products towards compactness and light weight, the use of high-capacity batteries with a single charge of more than 2.8Ah may become a trend.
Compared with low-capacity batteries below 2.5Ah, high-capacity batteries have higher requirements for material systems and product performance, and the screening standards for battery suppliers have been further improved. Portable power station is expected to become the next important downstream application of cylindrical batteries, which is expected to drive demand for 1.72 billion batteries in 2025.
● Midstream of portable power station industry chain
The midstream reaches of the portable power station industry chain are manufacturers that design, develop, and manufacture portable power station products. Both self-production and contract processing are common in the industry.
The development time of portable power station products is relatively short, and many companies are transformed from battery companies, power supply companies, and power bank manufacturers based on their technical foundations. At present, most low-end enterprises have small-capacity products, and most of them enter the market through low-price competition. Product homogeneity competition is fierce, and product quality and price are uneven.
● Downstream of portable power station industry chain
There are two channels, online and offline, and the two channels are divided into direct sales and non-direct sales. Portable power station products are mainly sold online.
3. Portable power station market drivers
The driving factors of the portable power station market include three aspects: the development of lithium battery technology, the rise of outdoor activities and the large demand in the emergency field.
● The development of lithium battery technology
Portable power station mostly uses lithium batteries as batteries. Therefore, the progress of lithium battery capacity and output power technology directly drives the improvement of the capacity of portable power station power supply. With the upgrading of lithium battery performance and the reduction of cost price, the potential market of portable power station is further expanded.
● The rise of outdoor activities
Outdoor activities are the application field with the largest proportion of portable power station power supply, accounting for 43.6%. Under the influence of the epidemic, indoor gathering entertainment and group tours and other travel methods have decreased, and outdoor activities such as camping have become popular, which directly promotes the development of the portable power station market.
● The large demand in the emergency field
Among the global portable power station power application fields, the emergency field accounts for 41.5%. In recent years, the number of major natural disasters in the world has increased, and the number of people affected and the scale of economic losses have increased. portable power station power supply is an important means to deal with emergency power consumption after disasters.
