What is the difference between an AC adapter and A DC adapter?
An AC adapter (or AC-DC converter) converts Alternating Current (AC) electrical power from the mains to a lower voltage Direct Current (DC). AC is the type of electrical power that is used in most homes and is derived from the power source.
An AC adapter typically includes a transformer and rectifier circuit to convert the AC electrical power to a lower DC voltage.
A DC adapter (or DC-DC converter) is used to step down the voltage from one DC source to a lower voltage DC source. This type of adapter is typically used to power small electronics from larger batteries, such as your smartphone from a laptop battery.
DC adapters are also used to convert different types of DC voltages, such as 12V to 5V in order to power small electronic devices.
How do I know what size adapter I need?
To determine which size adapter you need, you should measure the threads of the device or appliance you are connecting to. It is best to start by measuring the outside diameter of the male thread and the thread fit.
The outside diameter of the male thread is the distance across a circle formed by the outside of the threads, and the thread fit describes whether the threads are tapered, straight, or parallel. Once you have determined the outside diameter and thread fit, you can then determine what size adapter you need by finding adapters that match the thread measurements.
It is important to note that some of the most common thread measurements used in adapters are 3/8” or 1/2”. Once you have determined the size adapter you need, you should double check your measurements and make sure the adapter thread size is an exact match.
What are the different types of AC adapters?
