Buyer's Guide

A power conditioner is a device that processes, stabilizes, and cleans up the voltage coming out of an AC wall outlet. The power that power companies send out of AC outlets can vary— it can range in voltage as low as 80 or 90 volts or as high as 130 volts. Large surges in power can seriously damage your gear.

Every electrical device we use has a preference of what voltage it prefers. When it receives its preferred amount of volts, it will perform at its best. A power conditioner, depending on the model, provides a constant voltage output. One would improve the function of electrical instruments or a home theater system. The applications are endless.

To keep the performance of your devices at a high level, you should invest in a power conditioner. To help you choose the best one, we have provided advice on what features you should look for.

What does a power conditioner do?

A power conditioner goes through several phases to create a steady energy output with less radio and electromagnetic interference.


A power conditioner provides extensive filtering to remove noise and other artifacts from the power to provide clean AC to your devices.

Surge protection

Some power conditioners also offer surge protection. This will protect your devices from any powerful power surges. However, it is important to note that the amount of surge protection a device receives is not limitless, and the manufacturer will be able to tell you how much power it can take.

Voltage regulator

A voltage regulator is a high-level power conditioner and uses transformers and other technologies to maintain a regular 120-volt output. This takes AC power from the wall and will knock it down or bump it up accordingly.

Helps your gear

A power conditioner will improve the sound quality of digital devices, extend the life of your devices, and generally help your devices perform well.

Things to consider when buying a power conditioner

When choosing the best power conditioner for your needs, you should consider the following factors and features.

EMI filter

EMI filters protect against impacts of electromagnetic interference that can cause unwanted noise in electric instruments. As a result, unwanted electromagnetic noise gets diverted from the device and to the ground. This is sometimes called radio or electromagnetic filtering.

Voltage stabilization

Not all power conditioners stabilize the voltage to a set amount; however, these types of conditioners are undoubtedly more reliable and of higher quality.

Amount of outlets

Ideally, you want to be able to use your power conditioner on many devices at once. For this reason, you should choose one with at least 10 outlets.


If you get a power conditioner with a screen showing the output voltage, you will see that it is working properly and get the right voltage for your devices.


Make sure the line readings can be calibrated so you get an accurate reading of the voltage output.


To save confusion, you can buy a power conditioner that is clearly labeled with what each outlet does: analog filter, digital filter, and video filter.

Amp capacity

The amp capacity tells you how much power the power conditioner can absorb and transmit. The higher the number, the better. It needs to be able to handle the power that the device you plan to use it for runs on.

Series multi-stage protection

Series multi-stage protection protects your equipment from energy spikes. Never assume a power conditioner has this feature. Instead, always look for Series multi-stage protection (SMP).

Protect or disconnect

Look for “protect or disconnect” technology. This means if your device cannot diverge a power surge away from your device, it will automatically disconnect it from the power source.


You might want to look for a power conditioner with a USB outlet so that you can charge your devices with an added sense of security.

Length of cable

Unless you are happy to spend extra money on a suitable cable length, make sure that the cable is the right length for your needs. Similarly, make sure the plug is the right one for your socket. For example, if you live in the US and buy a device made in Europe, you may need to buy a plug adapter.

Amount of independent banks

Each bank electrically isolates gear. Therefore, it is recommended that you keep analog gear electronically separate from digital gear. The more independent banks your device has, the more electrical separation you can create between your devices.

Response time

If you use a power conditioner for use with musical instruments, the response time is significant. Ideally, you want as low a response time as possible.


Make sure your device has a warranty for at least one year, preferably longer. If you buy a device that will protect other pieces of expensive equipment, you will want some compensation if it doesn’t perform and they are damaged.

Customer reviews

When buying any product, always read customer reviews. This will give you a good idea of how well the product will perform in the long term. With any kind of tech such as this, there are many online forums to ask around about the device you want to buy.

Power conditioner price range

A power conditioner can cost as little as $100 and as much as $1000. There are more on the market above this price range, but it is probably not necessary to pay more than this.


Q. What is the difference between a surge protector and a power conditioner?

A. A surge protector will protect equipment from power surges, and that is all. A Power conditioner prevents voltage and electromagnetic fluctuations from causing problems by reducing noise and interference. However, a power conditioner can also come with the added feature of acting as a surge protector.

Q. Where should I place my power conditioner?

A. You should place a power conditioner on the ground. Do not put it on top of or near audio equipment as it creates electromagnetic fields that can interfere with the sound. You can still plug your amp into the conditioner providing the cable is long enough, and the power conditioner itself is far away enough.

Q. What is dirty power?

A. Dirty power is an abnormality in the quality of power that is being delivered to a device. This can include voltage variations, low power factors, frequency variations, and power surges.
