Potential Risk of Domestic Laptop AC adapter

In the market there are varied types of laptop AC adapters

. It's difficult to get a satisfying AC adapter. I used to find one for my Dv1345ea AC adapter. I have spent more than one month to check and compare. It's really demanding job. There are two problems in the domestic AC adapter market.

The voltage and current output:

Although the power is of consistent size, voltage and current output are different. So you have to know some professional knowledge of AC adapter.

When we talk about the performance of the AC adapter, naturally we think about the watts. As to this Dv1345ea AC adapter, it's 65W. Now, most mainstream notebook power adapter power setting is 65W. But here needs to be explained that the power supply voltage output and current output is not the same. Like this HP ac adapter, it's output voltage is DC18.5V, and the current is 3.5A. Thus for other brand adapter, it's not so compatible. There are some adapter output voltage is 19.5V, or less than 18.5V. That is to say, when you buy a replacement, check the voltage and the current of the original one. Then if the replacement is compatible with the original, you can release a little bit. But here is one more point that you should take into consideration.

The interfaces:

This is much important to take into account. Though the voltage and the current output are the same with the original one, what about the interface? Don't be deceived by the brags of the salesman. You know that different brands have different interfaces. And even the same brand also has a variety of interfaces. So be cautious when you try to buy a laptop AC adapter. The best way is to bring your laptop with you. If it do works with your laptop, that is a good deal.

However, some prefer to buy online. Then you won't know whether it's really compatible until you pay for it and get it. there is much potential risk. I usually purchase online because of the abundant products and reasonable price. Like this Dv1345ea AC adapter, it's really a nice product for me. Thus the first thing is the credit of the online stores. Like this hootoo, if there is something wrong with the product, they will return the payment of the product.
