What is portable power supply used for and how to choose

1. About portable power supply

How portable energy storage power supply works

The portable energy storage power supply is composed of a control board, a battery pack, an inverter, and a BMS system. It can convert direct current (DC) into alternating current (AC) that can be used by other electrical appliances through the inverter, and also supports a variety of interface DC output to charge various electrical equipment.

Lifespan of portable energy storage power

The typical lifespan of a portable energy storage power supply is about 500 to 2000 cycles. The number of cycles is the unit used to represent the life of the portable energy storage power supply. It is calculated from 0% to 100% power, and then from 100% to 0% power. The life of a portable energy storage power supply is shown in the number of cycles, because the standard life of the same model varies according to the conditions of use and the environment.

2. Portable energy storage vs power bank vs generator

The difference between portable energy storage and power bank

There is a big difference between the output of a portable energy storage power supply and a power bank. The power bank can provide about 10,000 - 30,000mAh of power by connecting to a smartphone through a Type-c data cable. The portable energy storage power supply supports the AC output of household sockets, and can support electrical appliances with a power consumption of more than a kilowatt, while the power bank cannot supply power to large electrical appliances.

The application fields of portable power supply are very wide. It can be used not only as home energy storage, but also in various outdoor scenes. It can be connected to high-power electrical appliances such as electric ovens, electric fans, mobile refrigerators, and mobile air conditioners.

The difference between portable energy storage and generator

There are many differences between generators and portable energy storage in terms of fuel, power, noise, etc. It looks like the same type of device, both for power, but is actually a completely different device.

Portable energy storage power supplies are powered by electrical energy stored in batteries, while generators typically use gasoline as fuel to generate electricity. The portable energy storage power supply can charge the built-in battery through the solar panel, while the generator does not have the charging function.

The power of the generator is relatively large. In general, generators tend to be more powerful than portable energy storage. But depending on product specifications, high-performance portable energy storage can also provide power as powerful as a generator.

The portable energy storage power supply has low noise. Due to the structure of the portable energy storage power supply, there is not much noise when charging and supplying power, while the noise of the generator is quite loud.

Using the portable energy storage power supply can be operated with confidence without worrying about the surrounding environment. Since no exhaust gas is emitted during operation, it can be used safely no matter indoors or outdoors. The generator uses gasoline as fuel, and it will emit exhaust gas when generating electricity, so it is not suitable for indoor use.

Portable energy storage power supply is easier to save and maintain. For portable energy storage power supply, it is recommended to charge it every six months, keep the power at 60%~80%, and put it in a well-ventilated place, away from high temperature and humidity. If it is a generator, not used for more than 30 days, all gasoline needs to be removed, if left in it, it may become clogged with fuel going bad.

3. How to choose a portable power supply

Choose by battery capacity according to usage

The battery capacity of the portable power supply is expressed in Wh. Wh is the power consumed per hour. It can be judged that the larger the Wh, the larger the battery capacity, and the larger the capacity, the larger the battery size. The battery capacity can be selected according to the intended use.

Select output waveform as sine wave

The power provided by the portable energy storage power supply can be divided into two types: sine wave and rectangular wave. It is recommended to choose a sine wave model. The waveform of a sine wave is similar to that of a household socket, and there are many types of equipment that can be powered. And square waves are not suitable for powering compact machines such as game consoles and personal power supplies.

Select by output port type

The type and number of output ports also vary from product to product. If you want to use the power supply in a wide range of scenes, it will be much more convenient to have the following three types.

4. Suggestions for the development of portable energy storage

Technological innovation breakthroughs need to be strengthened. If the products of China top 10 portable power station companies want to stand out in the fierce market competition, it is necessary to strengthen the technological innovation and breakthrough of the products, continuously inject vitality into them, and achieve long-term differentiated development.

On the one hand, it focuses on product function integration and innovation, so as to adapt to the market demand of different consumption scenarios. On the other hand, strengthen technological innovation and breakthroughs to meet the special requirements of portable energy storage for safety, economy, and portability.

Need to pay more attention to security development. Portable energy storage products have a larger capacity than ordinary mobile phone charging treasures, and have both DC output and AC output. The 220V voltage marked on most products exceeds the safety limit of the AC peak value of 42.4V, so it is more dangerous.

It is necessary to pay more attention to the safety protection of the product, and at the same time, pay attention to the safety of the product, and avoid using it under dangerous conditions such as heat source, fire source, and thunderstorm.

It is necessary to improve the industry standard system. While the market demand for portable energy storage is booming, there are differences in the performance and quality of core components of products. Products have problems such as inadequate safety protection design, unqualified production process and other safety hazards and quality defects.

It is urgent to improve the industry standard system, improve the evaluation criteria, ensure product quality, and optimize the market environment, so as to help the high-quality development of the industry.
