Many people may not be very familiar with outdoor power supplies. In fact, it is simply a large power bank. The difference is that it can output AC and DC, and can support various electronic devices. It can not only charge mobile phones, but also Drive fans, network equipment, notebooks, and even cook with a rice cooker, etc.
For application scenarios, in a nutshell, whenever electricity is needed, outdoor power supplies can help solve the electricity demand. For example, it is suitable for self-driving camping, RV travel, fishing, hunting and other outdoor travel scenarios, and can provide power for smartphones, tablets, drones, projectors, lights, car refrigerators, rice cookers and other equipment. It can also solve power shortage problems such as disaster power shortage, power outage, emergency rescue and so on. If it is combined with solar panels to form a small solar power generation system, in the event of a post-disaster grid failure or destruction, continuous off-grid power generation can be achieved for post-disaster life, ensuring the basic living needs of the victims.
Functional parameters of outdoor power supply
Generally speaking, outdoor power supplies have both AC output and DC output functions. For the AC output function, the DC power is converted into AC power through the inverter for output. It can be determined whether to output 220V, 110V, or 100V according to the mains voltage standards of different countries.
The DC output function can output conventional 48V, 24V, 19V, 12V, or 5V through a DCDC converter.
There are many parameters for outdoor power supplies, but general users need to pay attention to the following:
1. Power, the greater the power, the more electronic equipment that can be powered, and the richer the content of outdoor activities. For example, the car refrigerator has a power of 150W. If you want to drive the car refrigerator, the output power of the outdoor power supply cannot be lower than 150W. Now the output power of outdoor power supply generally has 250W, 500W, 600W, 1000W, 1100W, 1800W, 2200W and so on. According to Sun Zhongwei, chairman of Huabao Xinneng, the current mainstream output power in the market is about 500W, but there is a trend towards higher output power.
2. Look at the battery capacity, the larger the capacity, the longer the power supply time.
3. Look at the type and quantity of power supply ports. Domestic outdoor power supplies are fully equipped with 220V AC output. AC ports support most electronic devices such as sockets; USB ports and Type-C ports support fast charging, and now most of them can support PD and QC fast charging, which can improve the charging efficiency of mobile devices; some outdoor power supplies also support car charging. Charging output; In addition, the charging interface also needs to be paid attention to.
4. Look at the charging efficiency. The mainstream outdoor power supply can use sockets, car chargers, and solar panels to charge itself.
5. Accessory functions, for example, some outdoor power supplies add LED lights, some can be monitored in real time through APP, remote control switch, and some support wireless charging, etc.
