Classification of Portable Energy Storage Products

Portable lithium-ion battery energy storage power supply, also known as portable energy storage power supply, outdoor power supply, often refers to a backup power supply or emergency power supply weighing no more than 18kg, using lithium-ion batteries as energy storage components, using AC or DC for input charging (such as AC 220V, car 12V, etc.), the output is AC or DC (such as AC 220V, DC 12V, DC 5V, etc.).

Portable energy storage power supplies are roughly divided into two categories:

(1) Divided by charging capacity: 0.5-1kwh charging capacity is the mainstream product in the current market, with a high penetration rate, relatively simple product structure and system, and is developing in the direction of miniaturization, portability and fashion. The charging capacity is more than 1.5kwh, which makes up for the blank market between diesel generators and charging treasures. 0.5-1.5kwh portable energy storage can basically meet the needs of one person to many people for short-distance travel.

(2) Use with portable photovoltaics: some models support the use with photovoltaic panels, and can be charged through photovoltaic panels. Taking STW portable energy storage power supply as an example, installing two 100W photovoltaic panels can charge 80% in about 6.5 hours, prolonging the use time of portable energy storage products outdoors.

However, in recent years, with the improvement of people's living standards, the market demand for portable energy storage power has gradually expanded. At the same time, the types of energy storage power sources have become more abundant, incorporating more functions, such as adding USB PD fast charging, wireless charging, speakers, etc., while serving as emergency power supply equipment, further emphasizing product differentiation and user Improve the user experience and enhance the added value of the product.

The core of portable energy storage products is safety and convenience. With the continuous upgrading of industry technology, the capacity of portable energy storage products has gradually increased.
