Whether you’re a beginner or professional tattoo artist, you realize the importance of a tattoo power supply—after all, without one, your tattoo machine won’t work. 

That being said, choosing the right and best tattoo power supply can be tricky. In this article, we will teach you everything you need to know to make the right choice. We will also share with you the best tattoo power supply units on the market currently. 

So, let’s get to it! 

Tattoo Power Supply: All You Need to Know

When you create a list of everything you need to create your tattoo kit, a power supply should be second in order of importance. It is one of the most essential parts of any tattoo studio. It provides your tattoo machine with all the electrical energy it needs to do its job. 

Considering the importance of a tattoo power supply, it makes sense that buying the cheapest option may not be the best decision—you need a device that is reliable and trustworthy and has a steady output of power. 

In the past, tattoo artists had a tricky time when it came to powering their setup. They often had to use different types of power supplies that weren’t always considered safe. Luckily, things have changed and tattoo artists can now buy power supplies made specifically for the task at hand: tattooing. Of course, with the increase of options on the market comes a lot of confusion and it’s not as if tattoo power supply units on their own don’t trigger a lot of scratched heads, to begin with.  

To help you navigate these waters somewhat, here are the basics of how tattoo power supply units work. 


The first thing to understand is the types of power supply. You get analog and digital types. 

Digital tattoo power supply units are the more professional option since they’re considered more accurate when it comes to checking the power and voltage. You also have the option of checking the values while your tattoo machine is off. Digital units are also more user-friendly and don’t require a lot of experience using. These power supplies nowadays have a touch LCD screen making them much more intuitive than outdated models. 

You can also choose between unregulated and regulated tattoo power supply units. It is recommended that you purchase a regulated model to ensure you get an even more accurate reading of the voltage while you’re working. You’ll, however, have to save up a little longer as these machines run on the expensive side. 

That being said, analog tattoo power supply units shouldn’t be pushed to the side entirely. They’re known for providing steady reading output to tattoo machines.  

Besides the analog and digital options, you can now go wireless. These wireless tattoo power supply units are especially useful if you tend to get tangled up in wires as you work due to limited space. It also looks neater. 

For pure professionals, there’s the choice of dual power supply. These units can support more than one machine. They’re expensive but the ability to plug in a liner and shader and effortlessly switching between the two makes the high price tag worth it. 


The voltage a tattoo power supply uses is super important as it determines how much power your tattoo machine will have. Also, the higher the voltage, the more machines you can hook to one tattoo power supply. The strongest power supply will run around 18 to 20 volts. Of course, if you don’t plan on linking more than one machine to your tattoo power supply, you won’t need such a powerful voltage. 

That being said, you should never choose a tattoo power supply that runs under 8 volts. That is because shading should happen between 8 and 10 volts, while lining runs between 4 and 10, sometimes 12 volts. 


A quick search and you’ll see that some tattoo power supply units cost as little as $25 and others a whopping $500. Considering the different types of power supply units, especially unregulated and regulated devices, it makes sense that the price difference is so huge. 

Unregulated devices won’t eat up all your money but they’re not as safe and reliable as the regulated types. Regulated tattoo power supply units help control power fluctuations, which means you can count on consistent supply. This is good news, especially when running at a high voltage since it’s easy for clients to feel the tiniest of change or malfunction then. If you can afford it, go the regulated route. Heck, why not save a little longer and buy the best right off the bat. 

Now that we’ve got that covered, let’s discuss the best tattoo power supply units on the market.

After testing it, it became clear that it struggled to keep up with the power of coil tattoo machines, so we thought it best to remove coils from the mix entirely. That being said, you can plug in both your rotary liner and shader at once IF your machine isn’t too powerful. In that case, you’ll only be able to run one at a time. 

The foot pedal is covered with stainless steel, a welcome change that will contribute to its durability.
