A power adapter plug [ปลั๊กไฟ มาตรฐาน, which is the term in Thai] is a power supply for our gadgets. The adaptors simply plugged into the wall converting AC voltage to a DC voltage. It is also known as an AC adaptor and commonly known as a charger.
Types of Adapters use commercially nowdays:
Approximately 15 different standard systems of plugs are being used around the world, each of which has assigned a letter from A till O. Designs of plugs have gradually developed to reduce the risk of electric shock and fire. Adaptors allow travelers to connect devices to foreign sockets, but that does not change the voltage, you will still need the converter or transformer to avoid any kind of damage.
A charger mostly with usb plugs [ราง ปลั๊กไฟ data, which is the term in Thai] is used to charge our phones and tablets. The USB plug adaptors are a modern invention that is detachable too whereas the normal adaptor plugs are mostly used in household items or with the electrical appliances that needs high power supply to work.
Multi sockets adaptors allow the connections of more than one plug to a single socket. They are generally used for low power devices i.e. to charge phones, for TV, computers, etc. They may lead to severe accidents if overloaded.
How To Choose The Right Adapter?
Check your gadget’s back or read the guide book to know how much power in voltage or mAh/A does your device need to charge or to work. Start looking for adaptors once you figure out the required V or A of your device.
While choosing the adaptor:
The adaptor’s output voltage should match the input voltage of the device.
The adaptor’s output should be greater or equal to your device’s mAh/A.
The adaptor should perfectly fit your device’s power cord.
If you can’t find out the exact figure of voltage and mAh or A, or you are not sure on the pin type, or you want to use the same adaptor for few more different devices, then simply go for universal adaptors with converter or transformer as they directly control the voltage.
