Portable energy storage devices can be classified according to different standards.
From the core of energy storage - battery type, there are mainly lithium-ion battery portable energy storage devices and lead-acid battery portable energy storage devices.
Lithium-ion battery portable energy storage devices occupy the mainstream of the market. Lithium-ion batteries have the significant advantage of high energy density, which means that for the same volume and weight, it is able to store more electrical energy. This makes portable energy storage devices based on lithium-ion batteries more lightweight and compact, and convenient for people to carry around. And the self-discharge rate of lithium-ion batteries is relatively low, even if the device is not used for a period of time, the loss of electricity is relatively small. They have a long cycle life and can withstand multiple charging and discharging processes, which is a very critical feature for users who frequently use energy storage devices. In outdoor camping, hiking, mobile office and other scenarios, lithium-ion battery portable energy storage devices can provide reliable power support for mobile phones, tablets, small appliances and so on.
Lead-acid battery portable energy storage equipment has the advantage of relatively low price. Although the energy density of lead-acid batteries is not as good as that of lithium-ion batteries, resulting in the overall device may be relatively bulky, but its lower cost is a viable option for some users who are more sensitive to cost and have less high requirements for device portability. For example, in some temporary construction sites, or as a backup power supply in some small stores, lead-acid battery portable energy storage devices can meet the basic power supply needs.
From the point of view of output power, it can be divided into low-power portable energy storage devices and high-power portable energy storage devices.
Low-power portable energy storage devices are mainly used to charge some small electronic devices, such as mobile phones, smart watches, Bluetooth headsets and so on. The power output of such devices is usually within a few tens of watts, and they are small and compact in design, easy to carry in a pocket or small bag. For example, in the daily commuting process, if the mobile phone battery is insufficient, the low-power portable energy storage device can replenish the battery for the mobile phone in time to ensure that people can keep communication smooth during the journey.
High-power portable energy storage devices can provide power support for some high-power electrical appliances. Like some outdoor enthusiasts when camping may carry electric kettles, small induction stoves and other equipment, these appliances need high power to work properly. The output power of high-power portable energy storage devices can reach hundreds of watts or even higher, which can meet the needs of these high-power appliances. At the same time, in some emergency rescue scenarios, high-power portable energy storage devices can provide sufficient power for medical equipment, lighting equipment, etc., to ensure the smooth progress of rescue work.
From the dimension of use scenario, there are outdoor portable energy storage devices and indoor portable energy storage devices.
Outdoor portable energy storage devices are designed specifically for outdoor environments. They usually have a strong and durable housing that can withstand a certain degree of collision, drop, as well as adverse weather conditions, such as water, dust, shock and other functions. The interfaces of these devices are also relatively rich, which can meet the use of different outdoor appliances. For example, when camping in the wilderness, outdoor portable energy storage devices can provide power for camping lights, outdoor audio, outdoor photography equipment, etc.
Indoor portable energy storage equipment is more to consider the convenience in the indoor environment. For example, in the family, when there is a power failure, the indoor portable energy storage device can provide temporary power for some necessary appliances, such as routers, lamps, etc., to ensure that the basic needs of family life can be met. In the office environment, if there is a circuit failure, the indoor portable energy storage device can provide power for office equipment such as laptops and avoid work interruption.
