Switching power supply all the time and everywhere, how do you choose?

Mobile phone, computer, tablet, battery car, flashlight and so on these need switching power supply, and in life switching power supply everywhere, its model is more, and different power, although some can be universal, but under normal circumstances or according to the situation to use a special switching power supply. There are many types and brands of this kind of products in the market. Consumers generally need to select according to their own needs when choosing, or let businesses directly help us to recommend, so that they can quickly complete the purchase and will not affect our daily use. But if the quality of the selected switching power supply is not good, it is not only a waste of switching power costs, and may allow other electronic products to be damaged. So we must carefully choose the right brand, but also to understand some selection skills.

First, be clear about your needs. Under normal circumstances, we only think of buying switching power when the products we use fail. We can directly take the previous adapter to the corresponding store to buy. Basically selling electronic products or repair shops will have this kind of switching power supply, the price is about dozens of yuan to one hundred yuan, is not a very high price. And if you do not know what type of switching power supply you used before, then it is best to directly take their own use of products to the store to buy, try switching, switching power really meet our requirements after the purchase, so that you can avoid unnecessary trouble.

Second, choose the right brand. The brand of switching power supply is still more, and its service life is also relatively long, like the mobile phone power supply may be used several times a day, if its quality is not high, it is easy to have problems. I believe you are more willing to buy high-quality products, although the price of switching power supply on the market is about dozens of yuan, but because we want to compare the pros and cons of the product is still a certain difficulty, so we must choose brand products. The products of big brands or big manufacturers are tested by the authority department. The quality of their products is better. Although the unit price is slightly higher, there will not be much difference in price, which is more suitable for us to choose.

Third, determine the after-sales service. Switching power supply can basically be used for a few years, of course, this is to buy the product is a regular product on the basis of the long service life can be guaranteed. However, when we buy such products, it is best to confirm the after-sales service with the merchants. If there is a problem within a month of use, the merchants should provide unconditional replacement of the new products or help us carry out maintenance. It is not recommended to choose non-brand three no products, this kind of product quality is likely to have problems, and may even threaten our safety, and can provide better after-sales service business products are more quality assurance.

Personal purchase of switching power must choose professional products, brand products are about twice as expensive, but such products are more worthy of our trust, its use effect is better, but also more secure. And some high quality products produced by large manufacturers will not be too much higher prices, but also can ensure the use of products, more worthy of our trust. If you want to wholesale this kind of product, you must choose a variety of types of models, through professional manufacturers to wholesale products, so that it can also ensure its quality.
