5 Best Pedal Power Supplies In 2021

Best Pedal Power Supply

Building your first pedal board?

Looking for clean, silent power for all of your effects pedals?

Then you need a good pedal power supply.

No matter how many pedals you have in your chain or what level of musician you are, you’re going to need electricity fed to your effects pedals in order for them to operate properly.

But with all these terms like Voltage, Currency, and Isolation, how are you supposed to pick the right power supply for your needs and budget?

These are our top picks for the best pedal power supply in 2021.

Picking a Great Pedal Power Supply That’s Right for Your Board

When picking out the best pedalboard power supply, I kept in mind the following four essential pieces of information:

  • Voltage – Power requirement. Usually 9V, but ranges from 12V, 15V, 18V, even 24V. Minimum power must be met to power your pedal. NEVER add too much voltage –  will damage your pedal.
  • Current – Flow of electrical charge, measured in milliamps (mA). Minimum current is a requirement and exceeding current minimum is ok.
    • Required Current – Rule of Thumb: add up mA requirements of all your pedals and double it. This is what your power supply needs to be rated.
  • Polarity – AC and DC. Most pedals are 9V, DC, Center-Negative
  • Isolation – means each pedal is individually powered, as opposed to daisy chain power. Isolated power is more reliable and reduces unwanted noise due to ground loops.

That Pedal Show refers to these requirements using the acronym VCPI. To learn more, check out their video on power supplies.

My list of the best pedalboard power supplies includes options that addressed the VCPI essentials in a safe and dynamic manner so that a wide array of pedals could be properly powered.

Most notably, every option on this list features isolated power, as this is the best way to power your pedals.

I also kept in mind that doing this can get expensive, so I’ve included some models that power for less, but not at the expense of quality. I also made sure to pick some smaller and rechargeable (battery powered) options for traveling/touring guitarists.

There is no better place to start a list of the pedalboard power supplies than a tried and true staple of the industry. The Power Plus 2 from Voodoo Lab has been the go-to pedal power supply for professional guitarists for over a decade.

The Voodoo Lab Pedal Power 2 Plus is a compact power supply that is built like a tank and utilizes toroidal transformers for low noise. It requires a standard 120V power, so it can be used anywhere in the US. It has eight outputs, each with short circuit protection.

Even if one of your pedals were to go down due to a short circuit, the rest would still be powered. The box comes with all the required connections, including a detachable AC chord.


Each of the Power 2 Plus’s eight outputs are switchable between 9 and 12 volts, giving you greater flexibility for analog pedals. You will need a separate voltage-doubler if you want to power 18V pedals.  Two of the outputs are designed to handle 250 mA of current with the included red cables.

All of the outputs are set for DC, Center Negative polarity and are 100% isolated.

  • Ultra Low Noise
  • Sturdy build ready for the road
  • Can Sag 4V to 9V on last two outputs
  • 250mA max current
  • Bulky, won’t fit under mini pedal boards.

Final Thoughts on the Voodoo Labs Pedal Power 2 Plus

Though not the most versatile pedalboard power supply on the market, the Power 2 Plus is the perfect companion for analog pedal heavy boards. It has a solid construction that will last you a lifetime and is dead quiet. If you need other power requirements that this model doesn’t offer, I highly recommend looking at the rest of the Voodoo Labs power supply line.

Final Thoughts on the JOYO JP02

This is a great option if you are purchasing your first power supply for your pedals, you have a small board, or if you are on a budget. It will power just about any analog pedal but may not be the best option if you have a wide array of high current digital pedals.

  • Universal power from 100-240Vac meaning you can plug it in anywhere in the world

On the surface, the Power Grid 10 is like a Voodoo Lab Power 2 Plus on steroids. It has more inputs, more current potential, and also a larger price tag. In this case, the increase in price is very worth it once you realize what the Power Grid has to offer on the inside.

So it is no surprise that they will also make one of the best pedalboard power supply options ever. This will work for just about any pedal and it is the ultimate defense against noisy pedal boards.

4. Strymon Ojai Pedal Power Supply Review – Best Mini/Best Isolated

If you have a small pedal board, real-estate is at a premium. You can’t afford to waste any space on your board for a pedalboard power supply, but you also need a power supply that can power the most demanding pedals. The Strymon Ojai (pronounced “Oh Hi”) is the most powerful supply in its class.


YouTube video

The Strymon Ojai is a small, powerful wonder of technology. Compared to all the other products on this list, the Ojai boasts big numbers in the currency department, while maintaining a manageable price point and a tiny footprint.

It is fully compatible with the rest of the Strymon power supply family using the 24V thru jack, so you can chain two or more Ojai’s together for larger pedalboards and it will remain low noise and high power. It also has LED’s to indicate which outputs are working.


All five of the outputs on the Strymon Ojai are 9V and a whopping 500mA, meaning that any pedal can be powered by this supply. It can even be used to power modelers like the Line 6 HX Stomp with the right connections. All of the outputs are DC, center negative and are double isolated. This makes this the best isolated pedal power supply on the market.

Final Thoughts on the Strymon Ojai

Finding a powerful, reliable, and quiet power supply for your pedals was a challenge for a long time. Now, the Strymon Ojai has changed everything. This pedalboard power supply will fit under just about any pedalboard. While not the most dynamic in terms of voltage, it’s pretty crazy to think that power supplies twice as big as this can’t power as much as the Ojai.

Once again, JOYO has created a game changing piece of gear at an unbeatable price. This might be the best pedalboard power supply for anyone looking to put together a small rig to take out on the road, or even for gigging musicians that need versatility when it comes to their power supply without breaking the bank.

Find The Right Pedalboard Supply For Your Needs

9V Pedalboard Power Supply with 5 outputs

Doing just a little bit of research about what kind of power your pedals need can go a long way in building your confidence around gear, as well as give you peace of mind knowing that your pedals are operating at their best.

Choosing the best quality pedalboard power supply not only gives you a quieter signal, but it also protects your pedals and ensures that they will work year after year, not matter where you take them.

I’ll be the first to admit that spending money on a power supply for your pedal board isn’t as exciting as buying a great tremolo pedal or a great delay pedal, but you will only be able to get the most out of your pedals if you give them the right power. Thankfully, doing this doesn’t have to break the bank.

It is my hope that this list has helped explain how power supplies work and how you can use that info to make an informed decision about what kind of pedal power supply you need.

Once your pedals are powered, all that’s left to do is play the guitar!
