1、 Battery capacity
Battery capacity is the first consideration. At present, the battery capacity of outdoor power supply in the domestic market ranges from 100wh to 2400wh, and 1000wh=1 kwh. For high-power equipment, the battery capacity determines the endurance and how long it can be charged. For low-power equipment, the battery capacity determines how many times it can be charged and the power consumption. For long-distance self driving tours, especially in sparsely populated places, it is recommended to choose high-capacity outdoor power supply to avoid repeated charging
2、 Output power
The output power is mainly the rated power. At present, there are 100W, 300W, 500W, 1000W, 1800W, etc. The output power determines which electronic equipment can be carried, so when buying a power supply, you should know the power or battery capacity of the equipment to be carried, so as to know which power supply to buy and whether it can be carried.
3、 Electric core
The main consideration in buying power supply is also the battery cell, which is the power storage part of the power supply battery. The quality of the battery cell directly determines the quality of the battery, and the quality of the battery determines the quality of the power supply. The cell can realize overcurrent protection, overcharge protection, over discharge protection, short circuit protection, over power protection, over temperature protection, etc. Good cell has long service life, stable performance and safety.
4、 Charging mode
When the power supply is idle, the way to charge the power supply: the general power supply has three charging methods: mains power, car charging and solar panel charging.
5、 Diversity of output functions
It is divided into AC (alternating current) and DC (direct current) outputs according to the current direction. The outdoor power supply on the market is distinguished by the type, quantity and output power of the output port.
The current output ports are:
AC output: used to charge computers, fans and other national standard triangular sockets, flat socket equipment.
DC output: except AC output, the rest are DC output. For example: car charging, USB, type-C, wireless charging and other interfaces.
Car charging port: used to charge all kinds of on-board equipment, such as on-board rice cookers, on-board refrigerators, on-board vacuum cleaners, etc.
DC round port: router and other equipment.
USB interface: used for charging electronic devices with USB interfaces such as fans and Juicers.
Type-C fast charging: fast charging technology is also a technology that the charger industry pays more and more attention to.
Wireless charging: This is mainly aimed at mobile phones with wireless charging function. It can be charged as soon as it is released. It is more convenient and simple without charging line and charging head.
Lighting function:
Flashlight is also a must for outdoor lovers. Installing a lighting function on the power supply saves a small piece. The integration function of this power supply is more powerful, and it is also a good choice for outdoor lovers.
6、 Others
Pure sine wave output: comparable to mains power, stable waveform, no damage to power supply equipment, and more safe to use.
Weight and volume: Based on the current energy storage technology, the volume and weight of the power supply with the same capacity are quite different. Of course, whoever can reduce the volume and weight first will stand at the commanding height of the energy storage field.
The selection of power supply should be comprehensively considered, but the cell, capacity and output power are the three most important parameters, and the optimal combination should be selected according to the demand.
