It is often said that distance is like a mountain. For outsiders, power adapters are not very familiar with them, and many people even think that they are the same thing as power supplies. However, this is not the case. A power adapter is a voltage conversion device for small electronic devices, which can be found on our daily mobile phones and laptops. It can convert household voltage into a voltage suitable for electronic devices, providing protection for electronic devices.

When choosing a power adapter, we not only need to listen to the merchant's introduction, but also carefully read the label on it. As long as it is a product produced by a legitimate manufacturer, there will definitely be a clear label on it, which will provide us with multiple information, such as the model of the adapter. If the label is labeled as 120100, then its adapter is 12V1A; The tag will also contain the INPUT data of the adapter, followed by the OUTPUT data of the adapter, DC 12V=1A， It means that the rated voltage is 12V DC, and the maximum current is only 1A. With this number, we can calculate the wattage of the adapter. Many professional manufacturers of power adapters provide customized services to meet the needs of different customers, which is also a proof of the strength of the business.

The power adapters produced by KRECO undergo reliability testing before leaving the factory, including aging testing, estimation of mean time between failures, and drop testing. During the aging test, the power adapter will be aged for 2 hours in an environment of 40 ℃± 5 ℃ and under 100% rated load conditions; When estimating the average time between failures, ensure that the product is exposed to an environment of 25 ℃ and under input and full load conditions for at least 50000 hours; During the drop test, the product will be dropped from a height of 0.75 meters onto a 30mm thick hardwood, which is placed on an inelastic ground. Only products that fully meet the standards will leave the factory.

Due to the increasing number of manufacturers producing power adapters, it is still necessary to be cautious when choosing, especially when purchasing in large quantities and understanding the manufacturer's strength. KRECO has advanced product testing equipment and testing instruments such as constant temperature and humidity test chambers, salt spray testing machines, multi-channel temperature testers, fully computerized power supply comprehensive testing systems, and fully computerized electronic load aging cabinets. This ensures that the quality of power adapters from raw materials to finished products is up to standard, and customers can choose with confidence.
