The birth of the power adapter is to convert the 100~220V AC voltage of the home mains into the 5V~36V safe voltage of the general small portable equipment.
Adapter is a very important switching device, which can facilitate people to charge electronic products. Many people are not familiar with the nameplate identification and use of power adapters, now we will take examples to answer one by one
There are several items that need to be noted on the label of the power adapter (hereinafter called adapter).
First, it is the model of adapter.
For example, the model of the adapter is CGSW30A-120-2500, which tells us several information, such as the manufacturer’s code, power size, output voltage and output current
1.CGSW: Company code name
2.30A: indicates 30W power
3.120: indicates that the output voltage is 12Vdc
4.2500: Generation output current is 2.5A
Second, it is the adapter INPUT(input).
At present, all JPTPOWER products can use the universal voltage, generally 100-240V~50-60Hz, it can work normally under the voltage of 100V-240V.
Third, it is the OUTPUT of the adapter.
Two numbers can be used to calculate the power of the adapter quickly, i.e., (P=V*I) : 12V*1A=12W(P), indicating that the power supply is the adapter of 12W.Most laptop power adapters are suitable for 100 to 240V AC (50/60Hz). Basically, most laptops have the power supply external, with a power cord connected to the main computer, which can reduce the size and weight of the main computer.You can find that most power adapters are marked with power and input and output voltage.
With so many indicators, which one should users focus on?
Generally speaking, special attention can be paid to the output voltage in the use of the power adapter, because it relates to the working voltage of the power adapter. For example, if the electrical appliance is purchased in a country with a voltage of 110V, it will be burned in the use of the 220V power grid in China.
It is worth mentioning that the power adapters produced by JPTPOWER meet the certification standards of UL/CE/GS/UKCA/PSE and other countries. If you have any questions about the products, please feel free to contact us.
