What to Look For in a Garage Door Opener Surge Protector

Before purchasing the best surge protector for your garage door opener, there are some factors to pay attention to. We have made a short buying guide to help you choose the product that meets all your requirements.

Joule Rating

An appropriate jolt rating on the surge protector specifies the Joules range the unit can tolerate, and a bigger Joule rating means better protection.

So how many Joules of surge protection do you need? The answer depends upon what you aim to protect. Only the garage door opener or more electronics?

Here are some generic Joule rating standards:

  • 1000 Joules energy rating is more than enough for regular electronics such as laptops, consoles, or CCTV systems.
  • Above 1000 Joules surge protection is fit for workplace equipment and power tools.
  • Anything above 2000 Joules is perfect for expensive electronics.

So if you aim to protect just your garage door opener, a surge protector with a 1000 Joules energy rating would do just fine. If other electronics are involved, it is better to look for something around 2000 Joules or more.

Clamping Voltage

Even though Jouls rating is advertised on the packaging, the clamping voltage is equally important.

Clamping voltage refers to how quickly the surge protector detects the surge and shuts the electronics down.

Typically, the clamping voltage in the U.S. should be close to 110V and as close as 230V in the U.K. The more the clamping voltage varies from the previously mentioned values, the more likely the surge protector will fail to detect a surge.

Safety Rating

There are many different safety standards by a bunch of various companies and companies. It is natural to wonder which of these is applicable to garage door opener surge protectors.

Generally, the UL safety standard is what you should look for. UL is among several companies approved to carry out safety testing by the U.S. federal firm Occupational Safety and Health Administration (OSHA). OSHA has a list of approved testing laboratories, which are recognized as Nationally Recognized Testing Laboratories.

Electrical Testing Laboratory (ETL) is another independent lab that makes sure products meet the minimum safety standards.

Always check whether a garage door opener surge protector passed one of these standards.


It is pretty obvious that you want a more extensive warranty (and higher insurance payout if something goes wrong).

Not just for the apparent factor that if something fails, you’ll have the ability to make a claim, but for the signal that an extended warranty suggests about the quality of the garage door opener surge protector.

So you want to long for more extended service warranties and high insurance coverage payments on your garage door opener surge protector. Look for a business that has been around for more than five years, this being another indicator of the quality.

EMI/RFI Noise Filtering

The EMI (Electromagnetic Interference) and the RFI (Radio Frequency Interference) are other factors to check when buying a garage door opener surge protector.

Although these terms are used interchangeably, they’re technically not the same thing. However, in this context, we can treat them alike.

Many filters (low pass filtershigh pass filters, or bandpass filters) just enable special types of frequencies through, indicating a series of EMI/RFI emissions will be transmitted to the electronic being protected.

Subsequently, specific EMI/RFI emissions will not interfere with the efficiency frequencies of various electric and electronic devices.

To summarize, the objective of EMI/RFI is noise filtering is to remove electromagnetic and radiofrequency disturbance that will hinder the garage door opener surge protection. It is worth checking if the surge protector you want to buy has EMI/RFI noise filtering.

Number of Sockets

Depending on how many electronics you want to protect, the number of sockets is important. It makes the difference between a significant financial loss and saving for the dream car.

If you want to secure only your garage door opener, it is simple. A surge protector with one outlet will do the job. However, in case you need to power up some precious tools also, you need more outlets.

You might opt for a multi-plug extension lead. However, it is more expensive and takes up more locations, which isn’t perfect. Make sure you decide how many sockets are needed before you buy your garage door opener protector. If you need extra sockets for other electronics in your garage – know that upfront.

Diagnostic LEDs

It would be best if you had a way to confirm that your garage door opener surge protector is working. And this is what diagnostic LEDs are for.

Look for garage door opener surge protection that consists of diagnostic LED lights that verify power, protection, and line fault status at a glimpse.
