A top-notch quality power supply is essential for Ham/CB radio. The poor quality power supply can put the Ham system at risk. With an enormous range of options available, it is really hard to find a top-grade power supply.

Which supply is better, Linear or switch mode?

The switch-mode power supply supplies power by converting AC to DC, and hence the desired voltage is produced.

On the other hand, the linear power supply converts the high voltage of AC into low voltage VC.

The switch-mode supply of power is smaller and lighter as compared to the linear power supply.

However, the switch mode power supply may create high-frequency noise. The linear supply of power is less noisy but it generates more heat than the switch-mode supply of power.

Buying Considerations of Choosing The Best Ham Radio Power Supply

01. Fan Noise

Fan noise is one of the things that people don’t really bother about. However, if you end up getting a Ham radio power supply that is noisy, then you will definitely be annoyed with it.

Most of the cheap power supplies can have very noisy fans. Noisy fans will lead you to a point where you will not be able to bear the noise and then the power supply will become completely useless.

Hence, getting a power supply that has a quiet fan is the best option.

02. Compatibility and size

There are some power supplies that are versatile and they are compatible with various devices such as scanners, sound systems, and even cellular phones along with HAM/CB radios.

However, there are some power supplies that may not even be compatible with all kinds of HAM radios.

So, make sure that you get the power supply that is compatible.

Secondly, Ham radio power supplies come in different sizes and may have varying weights.

The users must figure out their space and then choose the size and weight of the power supply accordingly.

Most of the Ham radio power supplies are lightweight and they don’t occupy much space.

So, people will not really have a problem finding one that suits their space.

03. Durability

Durability solely depends upon the materials used for construction and the build- quality.

Power supplies that are built with cheap plastic will definitely not last for a long period of time because there is a greater chance of them breaking.

On the contrary, some power supplies are made with high-grade and aluminum and some are made high-quality plastic.

So, the better the quality of the material, the longer will the product last.

Instead of buying a cheap power supply with low-grade materials, it is better to opt for the ones that are more on the affordable side.

This way, the investment in power supply will be worthwhile.

04. Display

Some Ham radio power supplies come with displays and then there are some that don’t have displays.

The benefit of having a display is that it provides real-time information on the power supply.

Now, the displays are of two types. One type is the analog display and the other one is a digital display.

Some people prefer analog over digital displays while some prefer digital over analog because digital displays are easier to read.

So, the display is really a personal preference. People can pick the one that they like better.

05. Safety

One of the most important buying considerations is safety. Most of the Ham radio power supplies come with protection features. These features include:

  • Over-voltage protection: In case of an increased supply of the voltage, the device is able to protect the other devices connected to it and is also able to ensure the safety of the users.
  • Short-circuit protection: In electronic devices, there is always a chance of short circuits. A short circuit can end up ruining the devices connected to the power supply and can also be dangerous for the user. So, short-circuit protection is essential.
  • Over-heating protection: Over-heating is also likely in electronic devices and over-heating can also end up causing damage to your devices. Hence, it is important to have a power supply that offers overheating protection.

06. Auto-shutoff protection

The power supply can shut off on its own for various reasons. In this case, to prevent the Ham radio from the damage it is essential to have auto-shut off protection.

All the power supplies that we picked out have safety features that keep the users and the devices safe.

07. Noise elimination

The power supply must provide highly stable and filtrated power so that noise elimination can be achieved.

If the power supply is not stable then there will be interference. Most of the power supplies have to noise offset dials with which the noise can be eliminated.

08. Price

The last buying consideration is the price. Different brands and different models of power supplies have varying prices.

Of course, each individual may not have the same budget. Some may have a high budget while others may have a limited budget but the varying prices allow each individual to get a power supply that suits their budget.

One thing to keep in mind here is that very cheap power supplies are not worthwhile. They may be built with low-quality materials and they may also have a low build quality.

So, spending money on something that will not function well and will not last for a decent period of time is not worth it.

Instead, buying power supplies that may be more on the affordable side is a good idea.

FAQ’s of Ham Radio Power Supply

Can a smartphone be charged with a power supply?

The Ham radio power supply can definitely charge a smartphone but it is only possible if the unit has a USB port. Without a USB port, you will not be able to charge your phone.

If anyone intends to charge their phone with the Ham radio power supply then they should get the one that has a USB port on the unit.

What is a Ham radio for?

Ham radio is a great way of interacting with people. Ham radio allows chatting with strangers and people can just listen to the conversation if they don’t really want to be part of the conversation.

The coolest thing is that the internet is not needed for this interaction. Using a Ham radio can be entertaining and educational at the same time.

It can be used to educate people about various social issues. Also, governments may use Ham radios to spread important information.

Can a Ham radio be powered by other sources instead of a power supply?

Yes, Ham radios can be powered through other ways. However, if there is a large unit then it will definitely need a power supply but when it comes to smaller HAM radios, they can certainly be powered by other sources.

Smaller Ham radios can be connected to cars, trucks, and even RVs. There will obviously be a difference in the power supplied. Instead of 120V AC power, 12V of DC power will be used.

Do all Ham radios require a power supply?

No, not all Ham radios require a power supply. There are handheld radios which come with their own batteries so they don’t need a power supply. The batteries are usually rechargeable. With larger units of Ham radios, the power supply will be needed.

What if the power supplies too much current?

There is no need to worry if the power supply supplies too much current or has a greater capacity because the Ham radio will utilize the current that it needs.

If you have bought a higher-capacity power supply then that’s fine too because you can, later on, find a good deal of a larger radio.

Too much current can be problematic rarely but the safety features protect the devices from damage.

Can Ham power supplies be noisy?

Certainly, some of the Ham radio power supplies can be very noisy. This noise is because of the conversion of AC to DC.

Most of the radios have noise offset dials that help in overcoming the noise. So, make sure that you invest in power supplies that are less noisy.


This article contains the list of the best ham radio power supplies because power supplies are usually underrated.

People invest in low-quality ham radio power supplies and end up damaging their system.
