1, Design and Construction
Large capacity battery cells: High energy density lithium battery cells are usually used, with capacities ranging from several thousand watt hours to tens of kilowatt hours. For example, some commercial mobile power banks commonly used for outdoor activities or small commercial exhibitions have a capacity of 5-10 kWh, which can meet the long-term electricity needs of many devices.
Durable shell: The shell material is mostly high-strength engineering plastic or metal alloy, which has good compressive, seismic, and fire resistance performance. The shell design focuses on heat dissipation and may have structures such as heat dissipation holes or fins to ensure stability under high load operation.
Professional circuit design: Built in complex circuit protection system, including overcharge protection, overdischarge protection, short circuit protection, overload protection and other functions. At the same time, it has an intelligent charging management module that can adapt to different types of devices for charging.
2, Performance characteristics
High power output: With a large output power, it can generally supply power to multiple high-power devices simultaneously.
Multiple output interfaces: equipped with rich output interfaces, including AC sockets, USB-A interfaces, USB-C interfaces, DC output interfaces, etc.
Long battery life: A single charge can meet the long-term usage needs, which is crucial for commercial events such as exhibitions and outdoor activities that last for a long time.
3, Application scenarios
Outdoor activities and exhibitions, emergency backup power, mobile office and service vehicles
