1, stability
The stability of the power adapter is mostly the same. It is based on the performance of overcurrent protection, EMI radiation, voltage deviation, ripple suppression, cross load, timing, dynamic testing, etc., so as to determine whether the power adapter can be stable for a long time. run.
According to different environments, the data performance is different, and the stability is also different. For example, the domestic mains voltage is 220V, such as Japan, the United States, Canada, etc., the mains voltage is 110V, the stability of the power adapter in these two cases is different, but the power adapter has a voltage fluctuation range of 20%, and it is used abroad. Don’t worry too much.
2, convenience
Convenience is one of the main factors that everyone considers. Electronic products themselves are slowly moving towards a small and exquisite direction because of their convenience. Naturally, the same is true for power adapters. I believe no one would be willing to carry a big one with them. Convenience is based on the measurements, volume, and weight of the power adapter, and the lighter price will naturally be higher.
3, energy saving
Now we are advocating green travel and saving energy. I believe everyone can understand. Power adaption mainly comes from 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 power adapters produced by Green Giant can reach 85%. , This is already very good.
4. Durability
Except for food, the durability of all commodities 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 normal use to connect to the mains and electronic equipment, everyone often takes the power adapter, some bumps are inevitable, and the wire will be frequently flexed, which determines that its aging speed becomes faster. The life span is not that high.
5. Compatibility
Since there is no unified interface standard for power adapters, the products on the market today can be said to be ever-changing in terms of interfaces. Everyone should compare carefully when choosing. Another is that power adapters often have voltage floats. Power adapters with similar voltages can be compatible, as long as they do not exceed the maximum range of electronic products.
