Outdoor mobile power supply refers to the outdoor multifunctional portable mobile power supply with built-in lithium battery, which can store electric energy by itself. The outdoor mobile power supply is like a portable charging station that can be moved. It is not only convenient for charging, but also equipped with many USB interfaces, which can meet the charging needs of various devices.

In view of the cost performance, the first thing to look at is which kind of lithium battery it uses. For example, lithium iron phosphate battery, because its material does not contain cobalt and costly precious metals, has a longer service life and higher stability. Compared with lithium ternary and lithium ion batteries, the cost of lithium iron phosphate battery is relatively low.

The capacity and power of outdoor mobile power supply determine its price. For example, friends who like self-driving tours and camping suggest choosing the outdoor power supply with large capacity and high power. Although it is expensive, its stored power can be used for a long time. If it's outdoor live broadcast or outdoor shooting, it doesn't need to use outdoor power supply with too much capacity and power. Everything depends on your own needs.

If lithium battery is the "heart" of outdoor mobile power supply, BMS battery management system is the "brain" of lithium battery, guiding the continuous operation of internal parts of lithium battery, both of which are indispensable. Topband battery has its own BMS battery management system, which provides a series of safety measures such as overcharge protection, discharge protection, charge and discharge overcurrent protection, charge and discharge short circuit protection, charge and discharge temperature protection, voltage balance, etc. for each lithium battery. In addition, Topband battery is also responsible for each product, and establishes an after-sales service department to maintain and repair each returned product, It also supports customized services for lithium batteries and outdoor power supplies. Professionals have developed customized plans to ensure that every customer can order and use at ease!
