When we choose a power adapter, we usually consider what brand, quality, price, etc. In fact, we should also consider its stability, convenience and effectiveness. Let's follow the charger manufacturer to learn how to choose the right power adapter!
1, stability
The stability of the power adapter is basically the same, mainly based on the performance of over-current protection, electromagnetic interference radiation, voltage deviation, ripple suppression, cross load, timing, and dynamic testing to determine whether the power adapter can run stably for a long time.
According to different environments, the data performance is different, and the stability is also different. For example, the household power supply voltage is 220V, such as Japan, the United States, Canada, etc., the power supply voltage is 110V, and the stability of the power adapter in these two cases is different. However, the power adapter has a voltage fluctuation range of 20%, so you don't have to worry too much about using it abroad.
2, convenience
is one of the main factors to consider. Due to the convenience of electronic products, they are gradually developing in the direction of compactness and exquisiteness. The power adapter is naturally the same. I believe no one will want to take that big guy away. Convenience is based on the three-dimensional, volume and weight of the power adapter, and the lighter price will naturally be higher.
3, energy saving
Now we advocate green travel and energy saving, I believe everyone can understand. The power adapter is mainly based on the conversion efficiency. The initial power conversion efficiency is only 60%. Now with the advancement and development of technology, it can generally reach more than 70%. The conversion efficiency of the power adapter produced by Green Giant can reach 85%. Good.
4. Durability
For all products except food, durability can be used as a measure. Due to the environment in which the power adapter is used, its durability is relatively important. In addition to the normal use of power supplies and electronic equipment, we often use power adapters, some bumps are inevitable, and the wires are often folded, which determines that its aging speed is faster, and its service life is not so long.
5. Compatibility
Since there is no unified interface standard for power adapters, products on the market can be said to be changing with each passing day in terms of interfaces. When you choose, you should compare them carefully. The other is that the power adapter often has a voltage floating value. Power adapters with similar voltages are compatible as long as it does not exceed the maximum range of electronic products.
