Tattoo Power Supply Review Directory - Tattooing 101 (2024)

A tattoo power supply sends electricity into your tattoo machine to make it run. It also allows you to control the voltage, which directly affects the speed and power of your machine.

An experienced tattoo artist will adjust their voltage for different clients and for the specific job they are doing, like lining or shading. Today, we’ll go over everything you need to know about tattoo power supplies and share some recommendations with you.

• Reliability and consistent output
• Which style is right for your machine (RCA, clip cord, wireless, etc.)
• Ease of use

Regarding tattooing power supplies, there are two primary types: wired and wireless. Wired tattoo power supplies represent the traditional approach, where a cable connects the tattoo machine to the power supply.

On the other hand, wireless tattoo power supplies operate differently, as they utilize an RCA connection instead of a cable. This RCA connection enables compatibility with most rotary tattoo machines in the current market.

Chances are you've heard this term in recent years. Specific rotary machines in the market demand a "start-up" capability, meaning they need a higher power output when you first switch on your power supply. (Basically, you might have the power supply on, but until you reach a certain voltage, the machine won’t start moving - it needs a “kick start.”)

Once the machine is moving, it will stabilize shortly afterward. Knowing if this is a requirement for your machine can save you valuable time and frustration while searching for a suitable power supply.

Your tattoo machine will need to be powered via clip cord or through an RCA connection. Coil machines use clip cords. The prongs insert into the back of the machine, and the contact with those prongs helps to conduct the electric current through the machine.

Rotary machines use an RCA connection. You can either get a cord that has an RCA connection or you can get a wireless power supply that is RCA compatible.

Pen tattoo machines will use an RCA connection, though most come with their own battery and can be charged directly, so it’ll seem like you’re charging the tattoo machine instead of a separate piece.

Tattoo power supplies usually provide a voltage range of 4 to 12 volts, catering to various tattoo machines and styles. The general principle is that higher voltage leads to faster machine performance.

However, it's crucial to consider the specific type of tattooing and the level of detail required, as speed doesn't always mean the best results. Some tattoo machines are mechanically tuned for different speeds, and through experience, you'll discover the ideal voltage for your needs.

If you’re not sure where to start with your voltage, start low and then work your way up. Starting off with too high a voltage will tear up the skin. Which voltage is right for your machine will rely on your hand speed. This is why it’s important to experiment and find the voltage that works best for your unique tattooing style and preferences, as there is no “one size fits all” voltage.

The pedal serves as a switch for your power supply and is directly connected to it.

When you press the pedal, the current activates, turning on the tattoo machine. Releasing the pedal cuts the current, turning off the machine. However, it is possible for artists to tattoo without foot switches. If you opt for a wireless power supply setup, the pedal becomes unnecessary. However, if you use cables, it’s highly recommended.

Nevertheless, some tattoo artists use their tattoo machines without a pedal. In this scenario, the machine remains constantly operational, which may sometimes prove inconvenient. Ultimately, the choice depends on your personal preference. As you gain experience, you will likely discover the method that feels most comfortable and natural to you.

Our professional tattoo artists are putting tattoo power supplies to the ultimate test: actual tattooing.

They don't just look at the specs, they complete a full tattoo with the machine, assessing their performance across a range of techniques and skin types. From lining and shading to color packing, we cover it all.

In our reviews, we focus on the key aspects that matter most: reliability, adjustability, comfort, construction quality, and price. We also look at additional features, such as the power supply’s ability to deliver consistent power. (If the power supply is not consistent, it will show up in your machine’s performance through pauses or uneven movement of the needle.)

Below, you'll find our in-depth reviews, where you can find our ratings on each power supply, as well as key takeaways and whether or not we recommend the machine for new tattoo artists.
