Day by day more and more mobile phones
are with usb-c port, which makes type c phone charger very popularly used in the market. Type c phone charger have desktop type
and wall type, and there are usb-c 2.0 and usb-c 3.0, usb-c 3.0 is much faster
than usb-c 2.0, and more popularly used currently, usb-c 3.0 output is normally
3.8V-6.5V 3A, 6.5V-9V 2A, 9-12V 1.5A 18W, it is with PD, PD means power
delivery, which can transfer high power at one time, this is why your mobile
phone and tablet can be charged fast! And one more point, if normal usb-c port
not with PD, the output is only 5V 3A, it doesn`t charge so fast like the one
with PD.
Yidashun not only has home type-c phone charger 12W 18W 30W
48W 60W, but also car usb-c phone charger 24W, and they are also with
usb-ports, which can charge all different devices at one time anywhere!

According to statistics, if all households in China replace incandescent lamps with energy-saving lamps, then the annual total electricity saving for household lighting alone is close to the annual power generation of the Three Gorges Reservoir. Despite such a good power-saving effect, the majority of domestic new residential users are not buying energy-saving lamps. Older home users who still use incandescent lamps are also reluctant to abandon incandescent lamps because of the high cost of circuit modification and the cumbersome process.
If the relationship between incandescent lamps and energy-saving lamps is like a seesaw, the end of the incandescent lamp "sinks down", and the end of the energy-saving lamp should "rise up", but the fact is that the call for "increasing the class" of incandescent lamps is getting higher and higher, but The domestic energy-saving lamp market is a bit "not awkward", and consumers are not very good at buying it.
UnionPay letter analysis:
China has been producing energy-saving lamps since the 1980s. At present, there are about 500 production companies. In 1996, the output of energy-saving lamps in China was 100 million. In 2006, 10 years later, this figure became 2 billion. In terms of price, in 1996, China's export of energy-saving lamps can only sell for 3 to 5 dollars, while domestic consumers spend about 40 yuan for each energy-saving lamp; now, most domestic energy-saving lamps are only about 10 yuan. .
In general, China's energy-saving lamp industry is developing very well. However, the current popularity rate of household energy-saving lamps in China is still not very high, especially in the economically underdeveloped areas of the central and western regions and remote rural areas, people still use incandescent lamps more. The main reasons for the popularity of energy-saving lamps in China are as follows:
1, energy-saving lamps "saving electricity does not save money"
The comparison report of 23 brands of energy-saving lamp products released by the China Consumers Association on the 10th said that the main reason for the energy-saving lamps "saving electricity is not saving money" is that the lamp has low luminous flux maintenance rate and short life. According to the relevant person in charge of the China Consumers Association, the lumen maintenance rate represents the percentage of the original light output compared to the time when the energy-saving lamp is used for a period of time. The higher the lumen maintenance rate value, the longer the energy-saving lamp maintains the normal illumination condition.
Since the third quarter of 2006, China Consumers Association has joined the consumer associations in Beijing, Shanghai and Guangdong to purchase 23 brands of energy-saving lamps sold in the three markets, and entrusted the National Electric Light Source Quality Supervision and Inspection Center. The technical indicators such as power, color tolerance, initial luminous efficacy, and 2000-hour lumen maintenance are tested, and the relevant data related to safety and technical performance are compared with product prices.
The survey results show that the quality of energy-saving lamps currently sold in the market is uneven, even if the products meet the national safety performance, the technical performance is also significantly different. The measured power value of most samples is lower than the nominal value; the overall power saving effect of more than half of the samples is better, and the power saving level of 36% of the samples needs to be improved; the 2000 hour lumen maintenance rate is different, and the individual samples have short life. . By comparing the price and performance of the sample, it is found that the higher the price, the better the performance index.
2, the price of energy-saving lamps is high
The main reason for the cold weather of energy-saving products is the high price. In the lighting counters of supermarkets such as Wal-Mart and Tesco, the price of energy-saving lamps ranges from tens of yuan to hundreds of yuan, and the cheapest one has to be more than 10 yuan, while an ordinary incandescent light bulb is only about 2 yuan, and the price gap is wide. For example, an Osram bulb transparent ordinary lamp is only 2.4 yuan, but an Osram classic frosted ball energy-saving lamp is 34.9 yuan, the price difference is 14 times.
3, the old district uses energy-saving lamps to transform costs
According to the relevant energy-saving monitoring department, at present, the penetration rate of energy-saving lamps in new communities has increased year by year, but in some old communities, it is not optimistic. Relevant persons also believe that although new residential buildings or newly-built public buildings can use energy-saving equipment according to the design specifications, the use rate of energy-saving lamps in old residential buildings and old office buildings is not high, which is the bottleneck for the future promotion of energy-saving lamps. .
