First: be clear about your needs
1. Generally speaking, we only want to buy switch power adapter when the product we are using fails. We can directly take the previous adapter to the corresponding store to buy it.Basically sell electronic products or repair shop will have this kind of switch power adapter, the price is about dozens of yuan to 100 yuan, is not very high price.We just take the products we use to the store and buy them. We can also avoid unnecessary trouble by trying the switch adapter after it really meets our requirements.

2, before the purchase of switch power adapter can also search for some information onthe Internet to see, see the choose and buy the switch power adapter needs what methodand reference conditions, small make up in the "power adapter terms of reference ofchoose and buy" mentioned, in the choose and buy the power adapter is not just considerthe price, but mainly to consider the quality, weight, safety specifications and otherparameters.

Second: choose the right brand
There are many brands of switching power adapter, and its service life is also relativelylong, like the mobile phone power adapter may be used several times a day, if the qualityis not high, it is easy to have problems.I believe that we are more willing to buy high-qualityproducts, although the market price of switch adapter is about tens of yuan, but becausewe these non-professionals want to compare the advantages and disadvantages of theproduct is still a certain degree of difficulty, so we must choose brand products.The productof big brand or big manufacturer is checked through authoritative branch, the quality of itsproduct is better, although unit price wants a few higher, but won't have too big pricedifference, suit us to choose more.

Third: determine after-sales service
Switch power adapter can basically use a few years of time, of course, this is in thepurchase of products are regular products on the basis of the ability to guarantee longterm service life.However, when we buy such products, it is better to confirm the after-salesservice with the seller. If there is a problem within a month, the seller should also provideunconditional replacement or help us to carry out maintenance.It is no trecommended to choose non-brand sanwu products. The quality of such products is likely to have problems,and may even threaten our safety. Moreover, the products of merchants that can provide better after-sales service are also more quality guaranteed.
