What is Power Supply Adapter

AC / DC adapter AC adapter (AC adapter) (Japanese AC アダプター) (AC / DC converter), AC means alternating current, and AC adapter is AC power supply. Many electrical appliances use AC adapters. The name of AC Adaper is only used in commercial products. In fact, it is an AC power supply. In the industrial field, we call it switching power supply, but there is a little difference in appearance.

How to purchase AC/DC Adapter?

  1. Be sure to know the input voltage range of your power adapter. It’s best to use the world-wide AC100-240V voltage input, so that your computer can’t be used abroad, or it will smoke when you connect AC220V when you return home from abroad.
  2. Be sure to know the output voltage and current of your power adapter!

It is better to be completely consistent with the nominal voltage and current of your power supply. As for the brand, there is little difference in the quality of different brands, because many brands of power supply may come from the same power supply manufacturer and be OEM.

Although the output voltage and current of the power supply have a small variation range, the over-current and over-voltage protection points are accurately tested and set by the manufacturer. The load resistance values of different computers are different. Once some circuit faults occur in the computer, the power adapter can play a protective role. If the power adapter with non nominal voltage and current is selected, it may not protect the computer because its overvoltage and overcurrent protection point settings are different.

  1. Be clear about the aperture size of the DC output line end of your power adapter and the difference between positive and negative inside and outside. Don’t buy it home and find that it can’t be plugged in.

What does customer say about FBELE Company


Our company has just started to import Chinese products from this year and is not very familiar with customs declaration and transportation. FBELE has taken the trouble to help us handle the import, which has solved our worries at home. Very very very good service.


We choose FBELE as our partner because FBELE has its own plastic mold factory, which can help us customize products and provide prototypes, which provides a strong guarantee for us to design new products.
