Fast chargers are expensive because they use advanced charging technology and high-quality materials. Fast charge technology can provide higher charging power, so that the device can be charged faster. To achieve this, chargers need more powerful circuits and more efficient cooling systems, which increases manufacturing costs. In addition, fast charging appliances usually have higher safety performance and longer service life, which will also lead to higher prices. In short, the high price of fast charger is due to its advanced technology, high-quality materials and better performance.
Because the power is large, the chip is expensive and the wire core is thick
Because the fast charger does not hurt the phone battery, and it is fast to charge
Because it's faster than the average charger.
Because it can achieve fast mobile phone charging
