AC Adapter Manufacturer

With all the certifications UL, ETL, FCC, CE, CB, GS, CCC, CQC, PSE, KC, KCC, SAA, RCM, etc.

In recent years, there have been a lot of charging safety accidents, many of which are caused by the use of poor-quality chargers. Although low-quality chargers are sold at a cheap price, but because the product design is often defective, while those power adapter manufacturers like to cut corners. Therefore, in addition to not being able to work stably, it is also easy to burn out, which is a great safety hazard. So how do we go about recognizing the quality of a charger?

1. Observe the charger above the nameplate, labeling. Regular charger above the general text to indicate the origin, model, safety indicators, parameters, 3C certification mark and so on and the text layout in order, clear printing. And low-quality chargers are not so much to pay attention to, the parameters above are often not standard, layout confusion, printing is often not very clear, there are some low-quality chargers will be printed on the top of the English to confuse consumers.

2. Look at the shell of the charger. Genuine charger in the shell material selection requirements, the regular power adapter manufacturers are generally fire-retardant fire-retardant materials, the use of ultrasonic technology can do seamless integration, the shell is tight, sturdy. The poor quality charger shell is often not fireproof, shell gaps are large, and is not drop-resistant.

3. Look at the USB interface. Genuine charger USB interface is clean, neat, tight dimensions, the head of the data cable will be very tightly inserted. The low-quality charger due to the lower precision of the injection mold. In order to prevent the insertion and extraction of misalignment, often larger than normal size, so the data cable head sometimes can not be completely inserted, and sometimes inserted crooked.

Use genuine chargers to protect the safety of electricity.

Eahunt power supply manufacturers, do power supply we are serious, the selection of high-quality components:
Capacitors, resistors, transformers, PCB circuit boards, PC flame-retardant shells, etc., with solid material is not ambiguous. And there are some brand power supply is not necessarily. Although the power is the same, but the shell selection of poor materials, the internal also has no intelligent protection chip, charging process current and voltage instability.
