Power Adapter

The power adapter is  whether that heavier the better? Only some heavy material enough to be able to be called what? The more expensive the more power adapter right?  Power manufacturing experts - Shenzhen JiaQiYuan Power Technology  Co.,Ltd  with many years of experience and strong electron tell you, this is not so. Of course, the price of a good quality power supply must not be cheap, cheap power naturally put lower quality, or else there will not be such a big price gap. So some businesses tend to use cheaper power to deceive consumers, but some users do not fully understand their own opinion on this, but with only a few dollars difference a thousand dollars might incur losses, does have some worth, so buy Pay particular attention to the quality of the power supply when the adapter is fine. Supplementary question: how to look at supply good price another job is not a power of good or bad depends on many aspects, materials, power, whether active, many aspec...

 Science and technology in today's society more and more developed, whether production or life, almost every industry in every corner of every minute that people can not do without electricity, can not do without electronics. For dependent increase in power, we are required to have some basic knowledge of electrical safety, so as not to cause undue electricity be some accidents.        As we all know, switching power adapter is a small, portable electronic devices and electrical and electronic power supply conversion device. Switching power adapter in the past few years has made considerable development, it has been quite widely used in life. Such as games, learning language video machines, notebook computers , etc., needs to have complete switching power adapter, it is the energy treasure trove of these electronic devices. Switching power adapter has been able to get such a wide range of applications, but also thanks to its appearance of sm...

Power adapter and switching power supply is different, and their size, shape and size, the accuracy of density, performance and other parameters are different, their application is different. Power Adapter is mainly applied to small appliances, electronics, and switching power to control the entire switch switching current equipment for all electronic devices. The following small series to focus on explaining the characteristics of the power adapter and switching power supply as well as differences.   Characteristics of the power adapter and switching power supply   Switching power supply features:   The road is to use high-speed on and off by circuit control switch, the direct current into alternating current supplied to the high frequency transformer, resulting in one or more sets the required voltage. High frequency alternating current is converted to high frequency AC efficiency because the transformer in the transformer circuit is much higher than 50HZ, so switc...

Murray Slovick 29 July 2015 External power supplies (EPS) convert household electric current from a wall outlet into lower voltage direct current (DC) or alternating current (AC) to operate consumer products s​​uch as a laptop computer. External power supplies are so-called (“external”) because they come in a separate physical enclosure than the end-product, and usually provide power to the device through a separate cord and plug. The efficiency rating of a power supply is the percentage of total output DC power in relation to total input AC power. It is a measure of how much of the power is lost when it converts the AC w​​all outlet power to DC (with most of the loss during conversion taking the form of heat). As an example, consider that if a device consumes 300W of power, using a power supply unit with 85% efficiency will require about 350W of input power, and a 70% efficient supply will pull nearly 430W of power from the wall. More than 1 billion external power suppl...

China LED industry boom and government support are closely related. March, China National Development and Reform Commission clearly will spend 40 billion yuan for purchasing LED lights, and LED lights provide users with 30% of financial subsidies.  China led light supplier  are feel proud of this result. Local governments also will respond that since March 1 this year, the provinces financial investment in the construction of all lighting works and new regional planning and development in the field of public lighting always use the LED.Many people think  buy cheap led tube light  is a normal things in life. In addition, capital markets favored degree LED market is not reduced, as venture capital and private equity industry, the most popular one. Statistics show that in 2011 the country has seven LED industry enterprises in the A shares to achieve IPO, total financing amounted to 3.625 billion yuan. In February this year, the Com mission pub...

 Our life has become increasingly diverse, the now popular "Chinese Dream", and increasingly fantastic and wonderful; nowadays is not just a lighting fixture items, it is a lot of good Chinese dream of specific performance. China led light supplier is also take highly concern on this problem.as intelligence, communications technology, facilitation, life is no longer a problem, bring to life the endless wonderful lighting changes is the key. Currently in functional lighting stage, to be the next LED will experiential consumption direction. Currently stay more functional lighting market requirements, stay on the industrial product level, the next step should be to expand the number of emerging enterprise applications, the LED lighting products through innovation can truly allow consumers to make an experiential consumption of products. To buy cheap led tube light is a normal tend among people. Home-for example, the current update to synchronize lighting products and h...

This is a few years into the LED lighting industry, more and more enterprises, but most companies have not really look at the characteristics of the LED lighting industry, the situation and the market structure, no direction, causing many companies both in the production, sales or the channel layout looked very impetuous.   China led light supplier  believes that the future will face a large LED whipsaw eliminated at least 50% of the enterprise.                                                                                  Because of LED lighting products more expensive compared to traditional lighting products, the vast majority of home users see is the short-term cost benefits, rather than long-term energy efficiency will be the first place to consider, therefore, LE...

                                           Apple's 5W European USB power adapter. Apple has recalled adapter plugs sold with older iPhones amid concerns they might overheat. "In rare cases," Apple warns, the 5W European USB power adapter "may overheat and pose a safety risk." The adapter for European two-prong power sockets comes with the iPhone, and is also sold as a separate accessory. According to Apple, the only plugs with a problem are those that were sold with the  iPhone 3GS ,  iPhone 4  and  iPhone 4S between October 2009 and September 2012. A redesigned version comes with more recent phones. If you have one of the older, potentially defective adapters, Apple will swap it for one of the redesigned versions. Once they've verified your phone's serial number they will swap the old adapter for a new one, and dispose of the offending article in...
