How to choose a laptop power adapter?

When choosing a laptop power adapter, we often consider brand, quality, price and so on. In fact, we have to consider its stability, convenience and its effect. Let’s talk to you about what kind of laptop power adapter is a good adapter.

1, Stability

Power adapters are basically similar in terms of stability, and are based on overcurrent protection, EMI emissions, voltage deviation, ripple rejection, cross-loading, timing, dynamic testing, and more. So that the laptop power adapter can run stably for a long time.

Depending on the environment, the behavior of the data will vary and the stability will vary. For example, China’s power supply voltage is 220V. The power supply voltage in Japan, the United States, Canada and other places is 110V. The stability of the laptop power adapter is different in these two cases, but the laptop power adapter has a voltage fluctuation range of 20%. Don’t worry too much if you go abroad.

2, Convenience

Convenience is a factor that everyone should consider. The electronic product itself is for convenience reasons, the power adapter is naturally the same, I believe no one will be willing to carry the big guy. Convenience is based on the size and weight of the power adapter, the lighter price will be higher.

3, Energy saving

Laptop power adapter is mainly from the conversion efficiency, the initial power conversion efficiency is only 60%, and now with the advancement and development of technology, generally can reach more than 70%, some Samsung, Apple’s original laptop power adapter conversion efficiency can be as high as 85 %, this is already very good.

4, Durability

Due to the environment in which the laptop power adapter is used, its durability is relatively important. In addition to the normal use of connecting the mains and electronic equipment, some collisions are inevitable, and the wire will be frequently fold, which determines that it ages faster and the service life is not so high.

5, Compatibility

Since the power adapter does not have a uniform interface standard, there are many types of interfaces on the market today, so you should carefully compare them when you choose. Another reason is that power adapters typically have voltage floating values, and power adapters with similar voltages are compatible as long as they do not exceed the maximum range of electronics.
