1. What is an outdoor power
supply
An outdoor power supply is an outdoor multi-functional power supply with built-in lithium-ion battery and its own energy storage capacity, also known as a portable AC and DC power supply . The outdoor power supply is equivalent to a small portable charging station. It has the characteristics of light weight, high capacity, high power, long life and strong stability. It is not only equipped with multiple USB ports to meet the charging of digital products, but also can output DC, AC, car points Common power interfaces such as cigarette lighters can supply power to laptops, drones, photography lights, projectors, rice cookers, electric fans, kettles, cars and other equipment, suitable for outdoor camping, outdoor live broadcast, outdoor construction, location shooting, family Scenarios with high power consumption such as emergency power consumption.
Second, the working principle of outdoor power supply
The outdoor power supply is composed of a control board, a battery pack, an inverter, and a BMS system. The inverter converts it into AC power that can be used by other electrical appliances, and also supports DC output from a variety of interfaces to charge various digital devices.
Three. Outdoor power supply charging methods
There are mainly the following charging methods for outdoor power supply on the market: AC charging, solar charging, car charging, TYPE-C charging.
1. Solar charging
The outdoor power supply and portable solar panel are used together, as long as there is sunlight, the solar energy can be used for charging. A 400W solar panel can fully charge the outdoor power supply within 4 hours, providing a steady stream of power for various electrical appliances. In addition, outdoor power supplies mostly use universal input interfaces, which are compatible with a variety of solar panels on the market. Of course, some products on the market also support multiple solar panels connected and charged at the same time. Some can support up to 6 110W solar panels for charging at the same time.
2. AC charging
In any place with AC power, it can be charged through the AC interface. Similar products of the same capacity level on the market, the charging time is 6-12 hours.
3. Car charger charging
Users who are driving can charge through the car charger port, but the car charger charging is slower than AC charging , it usually takes about 10 hours to fully charge.
4, Type-C charging
If there is a Type-C input port on the product, it can be charged through this interface.
It can choose conventional charging or solar charging according to different usage conditions, can provide super-power 100-240V AC output, and is equipped with 5V/9V/12V and other DC output modules, not only It can start the car in an emergency, and is also suitable for emergency use of various types of loads.
