The Best Ham Radio Power Supply (Linear and Switching)

Writen by Edwin Jones

Fact checked by Andrew Wright

best ham radio power supply

A radio is a good mode of communication, especially during disasters. When cellular reception is unavailable, it connects you to others, even in a far-away land. Not to mention, it is your source of the latest weather alerts and other emergency warnings. However, it is useless without the best ham radio power supply.

Without an inverter or internal transformer, DC power is essential. It does not directly plug into an AC outlet. DC power performs better than batteries and will feed the voltage that a system needs. With this, the ham power supply is the blood that keeps a radio working.

The options are plenty, but it does not mean that they are all equal. To help you narrow down your choices, below are some of the important considerations:

  • Type: You will find two main types of power supplies – linear and switching. The main difference lies in how they work and directly influence the noise that they generate when operating. The specific type also affects their price and efficiency.
  • Safety: Consider the different safety features for your peace of mind. The best ones have protection against overheating, overloading, and short circuits. They will also help in minimizing damage.
  • Compatibility: Match the power supply to the requirements of your ham radio. From the voltage to the amperage, go through the technical details. Otherwise, you might end up under-powering your communication system.

Clueless about what to buy? Read on as I walk you through some of the top power supplies worth considering.

What to Look for When Buying Ham Radio Power Supply


With too many options for ham radio power supplies, deciding what to buy is an overwhelming task. Make things easier by considering the things I will talk about below.

  • Price

Most people will consider price as a primary factor. Do not buy a product only because it is cheap. Quality is more important. If you want to save money, consider a used ham radio power supply. Nonetheless, make sure to ask around and buy only from trusted sellers to enjoy the best bang for the buck.

  • Type of Power Supply

Linear power supplies are common if you are looking for low-noise output. The absence of high-frequency switching eliminates buzzing and static. It is a common choice in situations when you need low ripple or when there is excellent regulation.

On the other hand, a switch mode power supply delivers a higher efficiency despite being compact. It has a regulator that efficiently converts electrical power. It is also a good choice if you are looking for a more affordable alternative.

  • Construction

Look at the material, which is indicative of the quality of the construction. Steel is the most common material that you will find in a 12-volt power supply for ham radios. Stay away from those that are made of cheap plastic. More than being durable, see to it that it is lightweight, so you can bring it easily anywhere it is needed. The knobs and the buttons should also have solid construction.

  • Safety

Power supplies have different safety features for your peace of mind. Most of them can handle overheating, overloading, and short circuits. In most instances, the unit will automatically turn off before reaching the threshold. This will prevent fire and other hazards.

  • Ease of Use

Especially if you are a beginner, it is important to choose a power supply with a simple user interface. It is good to have a few buttons, which will minimize complications. It should also come with detailed instructions. The installation should also be a breeze. Look for one that is inclusive of the mounting brackets that you need for quick assembly.

  • Cooling System

A built-in fan is another must-have feature. It delivers effective temperature management, preventing the unit from getting too hot. More so, there should be a heatsink or vents in the body for better air circulation. The cooling system should adjust accordingly depending on the load. The fan, however, should be powerful without making a loud noise.

  • Compatibility

If the power supply does not match the technical requirements of the ham radio, it is useless. It will not provide the needed power. Match the voltage and the amperage, among other technical specs. Some of the products I mentioned above are adjustable, so you can use them in different situations.

Additionally, being compatible means matching it to the environment where you will use the radio. For instance, if you are installing it on a boat, then you will need a marine radio power supply, which is designed for outdoor use and to handle water.

  • Battery

This is one feature that is more common in higher-end products. A ham radio power supply with battery backup is good if there is no electricity. This way, the radio will continue operating. Although, it can add to its overall weight and size.

  • Reviews

It is good to read ham radio power supply reviews and learn from the real-life experiences of other people. Pay attention to what others are saying about the durability and performance of a specific product.

What Size Power Supply Do I Need for Ham Radio


When looking for a power supply, size is one of the most important considerations. It affects not just the price but also the overall performance. Picking the wrong size means that you are compromising functionality. It will be under-powered.

Most of the radios will have a 20-amp requirement. While you can choose to match it, a better idea is to find one with a larger output. In this case, a 50-amp ham radio power supply may seem to be too large, but it is a good size if you want to be sure. Generally, however, a power supply with 30 to 35 amps will suffice.

Can I Use a Computer Power Supply on a Ham Radio

Yes, you can use a computer power supply in a ham radio, but with a few conversions. Otherwise, it can be prone to noise and interference, among other things that will negatively impact audio quality. Honestly, however, I believe that doing these tweaks are not worth the time. It is better to look for a product that is specifically designed for radio.

How Do You Hook Up a Power Supply to a Car Radio

Hooking up a car radio to a power supply is a straightforward process. First, you need to make sure that they are compatible with each other. Check the technical details, including voltage and amperage. When you are ready, fix the wires of the radio to the power supply. Pay attention to connecting the right colors to the proper terminals. Finally, plug it into the source of power.


The best ham radio power supply provides the necessary voltage. It converts AC to DC, optimizing the best possible performance. While the options are plenty, they are not all the same. From the input and output to the cooling system, several factors will differentiate one model from the other.
