How to choose Laptop Power Supply

With social progress and high technology development, more and more people have their own laptop. When people use the laptop ac adapter frequently or in a wrong way, it will lead to the notebook life shorten, so how should we choose a good quality laptop power supply?

1. With the same voltage and output, can the universal laptop adapter be common used?

The basic principle is that a large current power supply can replace the small current power supply. Maybe some people will think large current adapter will burn Notebook, because the current big. The current actually depends on the load when the voltage is same. When the notebook worked in high-load operation, the current bigger, but when the books go into standby, the current is smaller.

2. Performance and safety are the preferred

As we know about cell phones battery, mobile phone battery explosion is due to using of counterfeit batteries. Also there are many power bank assembled by poor battery cell, the current output is unstable. While charging for digital products ,it will generate a lot of heat, low charging efficiency, and very easy to happen short circuit, burn expensive digital products; Also a lot of fake brand-name products sold modeled.

3.Certification

We know that electronics should have formal certification. Consumers can not only reply on the data (like higher capacity). Consumers should check whether there is a third party product certification or check if certification is complete. Third-party product certification assumed that products meet certain quality standards and safety requirements.Such as CE,ROHS,FCC,TUV and so on

4. Appearance of products

Many consumers do not concerned about electronics products appearance. In fact, I think this is very important. If the products looks unsightly, when we use it, we will not feel comfortable. People's emotions are not the same. But heart of beauty in everyone!

5. Practicality

Consumers like to pursuit of high data, such as a power bank 10,000 Ma.In fact, my personal view is that it is no need. Power bank used for emergency, use one or second time is enough. Who will use it many times when he or she is at home? So buy a suitable one is enough. It is easy to happen that consumers often buy something not really need when online shopping. So it is recommended that consumers must consider the practicality.

What worth to happy is that I bought one Tommox universal laptop adapter, which meets all the suggestions above mentioned. It was used for 2 years, with 8 auto connectors, can charge all my laptops in my house. It bring me a lot of fun. Tommox is a good brand can be trusted.
