Mobile Portable Energy Storage Industry**
Mobile energy storage: three consumption scenarios
Portable energy storage: suitable for outdoor travel scenarios, power supply for mobile phones and computers, etc., to meet the diverse portable needs of outdoor travel;In scenarios such as emergency preparedness and other scenarios, in tsunami-prone areas, a small power generation system can be formed with solar panels to meet the electricity needs of disaster victims. The market size is expected to reach RMB 88.2 billion by 2026.
RV energy storage: The lead-acid battery energy storage system is relatively mature and has been widely used by finished RVsIn recent years, there has been a trend to add folding solar panels for backup power generation. It is estimated that the sales of the RV battery market in 2026 will be 4$3.7 billion.
Home energy storage: due to the high price of overseas electricity + the stability of the power grid needs to be improved, it is expected to reach 26.4 billion US dollars in 2027. 
Portable energy storage

Portable energy storage is divided into three categories according to different needs and uses: outdoor activities, which are expected to account for 44% in 26 years, and outdoor leisure market, which is expected to account for 80% of the outdoor activities market, including long-distance self-driving, camping bases, photography and fishing, etc., and the main market is currently Europe and the United StatesThe Chinese market has great potential for developmentThe outdoor operation market is expected to account for 20% of the outdoor activities market, including outdoor aerial work.
Emergency preparedness is expected to account for 37% in 26 years, including flood rescue, mobile medical and epidemic prevention, etc., and the main market is Japan.
Other markets are expected to account for 19% in 26 years, such as on-board charging, DIY, and electricity consumption in areas lacking electricity.

Another important use is emergency disaster response: the market size is expected to be 2.02 million units in 2021, and the main market is Japan, which is expected to ship 1.26 million units in 21 years, accounting for 63% of the emergency disaster response market shipments. In the Japanese market, emergency disaster response shipments accounted for 87% of its total portable energy storage market in 21 years.
RV energy storage
Figure 3 Electricity consumption mode for RV energy storage.
RV energy storage is mainly divided into lead-acid batteries (dominant) and lithium batteries, with lead-acid batteries accounting for 97%. Lithium battery life advantages, replacement and modification occupy the main market, with a market share of about 76 in 20208%。Lithium batteries are currently mainly used in the aftermarket market. At present, the demand is still dominated by Europe and the United States. The ceiling of the theoretical RV PV storage market is expected to be 193.9 billion US dollars.

Household energy storage
Figure 5 Household energy storage.
The global portable generator market size was about 18.7 billion in 2020 and will reach 30.4 billion by 2026. At present, the pain points of overseas users' electricity consumption: Overseas power grids are relatively less stable than domestic & high electricity costs, the American Society of Civil Engineers reported more than 3,500 total outages in 2015,lasting on an **erage of 49 minutesIn order to cope with this problem, overseas households are generally equipped with emergency power generation devices, which have the disadvantages of high cost, high noise and high pollution.
Advantages of household energy storage: stable electricity consumption + low cost, with policy subsidies.
At present, the main market for home energy storage is Europe.
