The likelihood is that if you’re sorting out the electronics in your home, you’re going to come across an AC adapter at some point. But, many of us aren;t exactly sure what an AC adapter is, and how it works too.
Fortunately, it’s pretty easy to understand and differentiate an AC adapter from the other parts of your accessories, like the charging cable or the ports that you’re using with it. So, let’s look closer at AC adapters and how they work.
What is an AC adapter?
An AC adapter is simply a type of power converter that we can use to power electrical devices around our homes. They can be used to deliver charge into these devices that don’t have the ability to recharge themselves.
One of the most common misunderstandings about an AC adapter is likely because of it’s name – people think that the “adapter” means that it’s more connecting two different style devices together. Sort of like a HDMI adapter, which could connect a HDMI port with another type of port.
But an AC adapter is called such because it literally adapts the type of current that’s used to charge your laptop or device. It coverts the current from an AC (alternating current) to a DC (direct current).
AC vs DC
Many people wonder about what the actual difference between AC and DC even is in the first place, and why it needs to be adapted. In an AC setup, the direction that the current is flowing can change periodically, which is down to the construction of the generator that’s used with it. However, DC is only flowing in one direction.
Essentially, you home is going to use AC running through it. But, the majority of tech devices that we use around the house are actually going to need to use DC instead. So, how can we get the AC “adapted” over to DC? Yep – a good AC adapter should be able to do the trick.
Why are AC adapters used?
If you’re still wondering why AC adapters are even used, then there are several reasons for using them. Here’s just a few of the main reasons why we stick with using AC adapters;
AC Adapters vs Chargers
Generally, we can definitively separate chargers and AC adapters from one another, even though you might have both of them combined into one plug or device.
Whilst an AC adapter specifically refers to the part of the charger that’s going to convert the energy current over, the charger is actually the parts that’s doing the.. well, charging!
A good example of this is with a power bank, which we typically think of as a charger. However, really a power bank is converting the charge from the lithium batteries in the device, so a power bank is also made up of an adapter as well as the batteries, which are the charge.
Are AC adapters universal?
Another very common question about AC adapters is whether they’re universal, and whether they can be used interchangeably on a variety of different devices.
The truth is that with this, it really depends on the adapter and charger that you’re using. This will come down to the voltage and amperage that’s listed on your adapter as well. Ideally, you want to use as close to the original as possible in this case if you want to use a different adapter with your device.
So, if you can make sure that the voltage is the same on both, then you can use a different AC adapter with a different device that it’s original companion.
All in all, AC adapters provide a pretty essential function that most of us need on a day to day basis. The ability to switch or convert the current of our electricity is a necessity, and a good AC adapter is the perfect way to do this. So, they’re an important part of your home setup.
