The reasons are as follows
< br >
1. Quality
< br >
When it comes to price, we should first say how good the quality of outdoor power supply is. Outdoor mobile power supply as a new category and emerging market segment, the most important factor is the safety and stability of the product, for the safety of each user, outdoor power supply with its own influence can lead the outdoor portable power supply category to healthy competition, but also the formation of outdoor equipment market new consumption points and market prospects. Then its quality is certainly beyond doubt, the use of American MPS \/TI chips and Diodes semiconductor devices, mature technology, high conversion efficiency, stable performance. Multiple output interfaces, multiple protection. Using dynamic\/cylindrical lithium-ion battery (18650), mature technology, high reliability; Charge and discharge more times, providing ideal battery life for mobile phones, tablets, digital devices and other appliances.

2. Function
< br >
The general capacity of outdoor mobile power is up to 274800mAh, and the power is from small to large, which can support high-power equipment, such as outdoor photography lighting, outdoor self-driving cooking, projection, audio and so on. Outdoor power supplies can power in-car refrigerators, power projectors, charge 12-inch Mac books, and power home rice cookers, which are not available in most mobile power supplies on the market today. It is worth mentioning that the outdoor power supply also has a suitable solar charging panel, which can be powered by solar panels in addition to the power supply of its own savings, and can also be charged by the car's wire during driving, which can fully ensure the continuous use of electrical appliances. Both sides have intelligent temperature control radiator and lighting, which can be used as sos emergency mode at night outdoors.

The most important thing in the use of outdoor mobile POWER is of course safety performance, outdoor power with built-in NCM battery with Tesla POWER WALL, charge and discharge cycle life of up to 500 times, 13 safety protection functions, 9 quality inspection processes, output power conversion overall higher than the industry 5-10%. Among them,DC to DC 95%,DC to AC 85%, multiple safety protection, avoid excessive charge and discharge, short circuit and other dangers, intelligent temperature control system, automatically adjust the charge and discharge temperature, extend the life of the machine. At the same time, the fuselage adopts the PC ABS fireproof shell, which is earthquake-resistant, corrosion-resistant, and has excellent high temperature insulation to avoid the danger of leakage. Gives it 66% more cycle life than any other power source.

4, the use of a wide range of factory view
< br >
Outdoor mobile power supply can solve all outdoor electricity problems, and the scope of application is also very wide, such as outdoor self-driving process can supply power to car refrigerators, computers, ipads, rice cookers, electric fans and other equipment; Can also solve the problem of family emergency, such as power failure can be wifi, air conditioning, refrigerator, mobile phone, induction cooker to charge; It can also provide power for ventilators in hospitals, fire fighting channels, disaster relief and other places. Therefore, the outdoor power supply can be called an electrical artifact, and the multi-scenario application can supply power to a variety of devices at the same time, with strong compatibility, high safety and long life.

So outdoor mobile power is expensive reason,
With the popularity of today's mobile phone fast charging technology, more and more charging banks have also been connected to this technology, so the difference in circuit board design and battery selection used by fast charging and slow charging is indeed one of the reasons for the difference in the price of charging banks.
In terms of battery charging management, the big brand of charging treasure will have more advantages, the general charging treasure will have overdischarge protection, overcharge protection, short circuit protection, overvoltage protection, overcurrent protection and other basic protection functions, but the more expensive charging treasure may also be equipped with anti-reverse protection, core temperature protection, electromagnetic field protection, etc. What is more, it will have a certain amount of protection when falling and shaking, not only so big brand charging treasure often has low power consumption, low discharge rate when not in use at rest, and other functions, which are generally those cheap miscellaneous charging treasure can not be compared.
1, Huawei mobile power uses polymer cell batteries, the cost is very high.
