A portable power station, also known as a portable generator or a portable battery pack, is a device that stores electrical energy and allows users to access power on the go. These portable devices are typically charged using a standard wall outlet and can then be taken anywhere to provide power to a variety of devices.

One of the main advantages of a portable power station is that it can be used in a variety of settings, including camping, tailgating, and as a backup power source during a power outage. They are also often used in remote locations where access to traditional power sources are limited.

The size and capacity of portable power stations can vary greatly. Some are small enough to fit in a pocket or backpack and are designed to charge a single device, while others are larger and can power multiple devices at once. The capacity of a portable power station is measured in watt-hours (Wh), and the higher the watt-hours, the more devices it can power and the longer it will last.

Portable power stations can be powered using a variety of sources, including lithium-ion batteries, lead-acid batteries, and solar panels. Lithium-ion batteries are the most common type of battery used in portable power stations due to their high energy density and low weight. Lead-acid batteries are less expensive but heavier, and solar panels can be used to charge the power station during the day, making them a good option for outdoor use.

In addition to providing power to devices, many portable power stations also have additional features such as USB ports, AC outlets, and even built-in flashlights. Some models also have the ability to jump start a car in case of an emergency.

Overall, a portable power station is a convenient and versatile device that allows users to access power wherever they go, making it a great option for those who need to power their devices on the go.

At this stage, 5,000 square meters have been put into use, with a monthly production capacity of 5 million US dollars. The second phase of the factory building is planned to add 5,000 square meters in the second quarter of 2023, and the monthly production capacity will reach 10 million US dollars by then. The third phase of the plant plans to add another 5,000 square meters in the fourth quarter of 2023, and the monthly production capacity will exceed 15 million US dollars.

Portable power supplies can power various electronic devices, including mobile phones, tablets, laptops, digital cameras, lighting, and so on. However, it should be noted that different portable power supplies have different output power and port types, and users need to select appropriate power supplies based on the needs of the device.

The capacity of portable power supplies should be selected based on user needs. Generally speaking, ordinary mobile phones can be charged 2-3 times using a 10000 mAh power supply, while laptops require a larger capacity power supply to charge. Users can choose the appropriate capacity to meet their needs according to their needs.
