12V to 5V Converter – Everything you need to know in 2023

Many appliances rely on a 5 volt power supply. For example, any piece of equipment that gets its charge from a USB cable is likely to use 5 volts. If you attempt to put 12 volts through the device you are likely to blow the capacitors and could even cause your device to burst into flames. Yes, that includes your cell phone.

In short, if it is designed to handle 5 volts, you need to make sure it is getting 5 volts. Of course, the domestic supply is different depending on where you are in the world. The US and Canada have 120 volts. In contrast, the UK uses 230 volts. 

Regardless of where you live, this voltage is too high and you’ll need to plug in a 5 volt adapter to get the right power for your device.

However, what if you have a 12 volt power supply available? There are plenty of batteries that offer just 12 volts and you can even get transformers that reduce your home supply to 12 volts. The good news is that you can get a 12V to 5V converter, you simply need to choose the right one.

Things To Consider When Choosing A 12V to 5V Converter

In order to get a good 12V to 5V converter, you need to think about several factors first. This will help to ensure you get one that will last.

  • Manufacturer

Perhaps the most important element in your decision process is who made the converter and who is supplying it. In a perfect world, you will have heard of both the supplier and the manufacturer. You may even have personal experience with both of them. This will give you the confidence to buy their products.

However, in the real world, this is not always the case. Instead of knowing the supplier and manufacturer, you need to discuss them with your family and friends. They may have personal experience that can be beneficial to you.  

If this isn’t an option then you should take a look at social media and online forums. There are plenty of people online willing to share their experiences. This can help you to make the right decision regarding the best 12V to 5V converter. 

  • Stability of Supply

A high-quality 12V to 5V converter will be able to stabilize the power transformation. A lower quality unit will not. Unfortunately, this means the power supply will fluctuate and these small power surges can be enough to damage your equipment.

Of course, you may struggle to prove this is the case, leaving you without a device or a power supply converter.

In general, it should be noted that the cheaper the product the more likely it is to be of poor quality.  You should consider your budget and stretch it as much as possible to get the best possible converter. 

  • Type of Converter

You can make a 12V to 5V converter yourself. This isn’t advisable unless you know what you are doing. The alternative is to buy one. But, there are many different styles available. It’s important you choose a type that suits your needs.

In other words, you need to choose how neat the converter will be based on where it is situated and what it will be powering. 

Final Thoughts on 12V to 5V Converters

Whatever you intend to use your 12V to 5V converter for, you can be certain that it needs to be reliable and durable. That allows you to put it into the system and leave it in place, knowing it will do its job.
