A low-quality AC adapter holds the power to ruin the most expensive gadgets at your home. To prevent such an ordeal, join us as we take you through this comprehensive buyer's guide and teach you exactly how to buy these adapters.
AC stands for alternating current, and DC stands for direct current. We use both these types of current in our everyday life. While the power from your wall socket is AC, the power used in devices such as computers is DC. An adapter helps us convert AC to DC to power up our devices.
A barrel connector is a type of output connector you will find in most AC adapters. It comes in many variations, but the most commonly used one is the DC plug. A barrel connector plug is shaped like a hollow tube, and while its socket is also similar-looking it has a metal pin inside.
The first thing you want to check when buying an AC adapter is what output plug it uses. Most adapters use a barrel connector plug or some type of USB plug. Even if the adapter you want does not come with a compatible output plug type, you can usually find converters that can be attached to it to make it compatible.
Voltage is another important factor to consider when figuring out the compatibility of an adapter, so it is best to go for an input voltage of 100V-240V. You also need to check the DC output voltage of an adapter to ensure it matches the input DC voltage of the device you want to connect with it.
An adapter's input and output voltages can be found in the product description, and the input DC voltage of most devices can be found in their user manual or product label. You can also use online guides to walk you through the process of checking voltage compatibility.
You should look for features such as overcurrent and short-circuit protection in an AC adapter. This will ensure your device’s safety, potentially saving you a lot of money in repairs. You can see what protection features an adapter has by going through its product description.
It is best to measure the cable length you need before buying an adapter. When picking an AC adapter, ensure the cable length is slightly longer than what you measured. This way, setting up the adapter will be much easier. You can usually find the cable length in the product description.
We only chose compact AC adapters for our list. This way, portability and ease of storage are ensured. You can check the compactness of an AC adapter by looking at its product description, where the dimensions are usually stated.
All of the products on our list are very easy to use and require next to no setup. This will save you time and effort in the long run. The adjustable SHNITPWR AC adapter from our list even has a knob controller and an LCD to make it easier to use. You can get a good idea of how easy to use your new AC adapter is by sorting through customer reviews.
