9 Best Single Outlet Surge Protector Reviews in 2021

People spend thousands of dollars on electronics and home. No matter how top of the line any product is, it is susceptible to damage in cases of high power surges. A good surge protector will absorb the spike in voltage and protect the devices from frying and housefires.

The latest surge protectors come with multiple outlets so that you can connect many equipment simultaneously. However, they won’t suit heavy appliances as they consume high energy.

The single outlet surge protectors have higher surge protection ratings which allows them to protect heavy electrical appliances. The surge protection rating differs from one surge protector to another. Besides, you should also ensure the surge protector’s clamp voltage can handle the socket’s output voltage.

Below are the primary features you should check before purchasing the perfect Single Outlet Surge Protector

Surge Protection Rating: The ratings are measured in joules. The greater the joule rating the better the protection. For smaller gadgets like phones, headphones etc, a protector of around 1000 Joules is enough. For bigger equipment, select a protector within the range of 1000-2000 Joules. Protectors with more than 2000 joules are ideal for home theatre, gaming consoles and PCS.

Clamp Voltage: It is the maximum charge of voltage that a surge protector will absorb during a spike before cutting off electricity to the device. Before buying your surge protector check the optimum rated voltage of your outlet. Make sure that the protector’s clamping voltage is lower than the maximum voltage that can be safely drawn out of your socket.

Warranty: Although a common factor in any purchase, its importance is compounded when buying a surge protector. In cases where the protector fails to cut the surge in power supply and destroys any equipment, the warranty will ensure an easier claim for the damage done. Most brands offer a lifetime warranty on their surge protectors. We recommend you get a surge protector backed by at least a 1-year warranty.

Your search for the perfect single outlet surge protector doesn’t end here. There are several other secondary features you need to consider to ensure that your needs are met. You can find the complete list of such features in the Buying Guide section of our article. But, before heading to that, please check out our curated list of the Best Single Outlet Surge Protectors 2021

Factors to check Before Purchasing the Best Single Outlet Surge Protector

Apart from the primary features, a few other things to keep in mind are the clapping voltage, maximum amperage, and safety rating. Other features might seem secondary but would matter depending on the usage of the protector. Below is a complete list of features you to check before choosing the perfect Single Outlet Surge Protector

Noise Filtering

Surge protectors often come with a label mentioning EMI/RFI noise filtering. EI stands for Electromagnetic Interference and RFI for Radiofrequency Interference. In single outlet surge protection jargon both these terms are treated equally but for all other purposes, they aren’t used interchangeably.

Protectors come with varying filters like low pass, high pass and bandpass filters. The purpose is similar, that of restricting unwanted frequencies and letting only the useful one pass. Not all EMI or RFI emissions affect the protectors’ performance. The noise filtering system figures this out and doesn’t stop every interference. So having this noise filtering function in your surge protector is an added advantage.

Safety Rating

There aren’t set guidelines or commonly accepted security standards by any organization that benchmarks safety rating power surges. Experts have urged buyers to consider UL ratings before going for a purchase. Previously known as Underwriters Laboratories, they are a global safety leader that test, inspect and certify products and set market standards.

The OSHA’s (Occupation Safety and Health Administration) approves product testing and UL is one among the many that have got the certification to give a safety rating. For Surge Protectors, the safety benchmark is UL 1499. Check the rating before buying one.


Diagnostic LEDs are a way for you to make sure that your surge protector is working. Surge protectors with a single LED display will keep lighting till it’s working and go off once the protection wears off. The most common LED setup is the traditional red-green lights. The green implying that everything is fine and the red prompting you to buy a new protector. Few of the higher end surge protectors will have extra LEDs to provide one-glance information about your device. More LEDs would also mean a bigger protector that occupies more space.

Size and Weight

Depending on what and how you are using the protector either both or one of the factors becomes essential. A General concern among buyers is about the design efficiency of the protector. Some protectors have extra non-functional space that might cover the adjacent sockets which make plugging in little devices on one board difficult. This could be a hindrance for users that have arrangements like console setups.

Safety Alarm

The LEDs are a useful hint to evaluate the working of your surge protector. But this also requires constant monitoring and could also result in negligence leading to damage to the appliances. To cover this, some protectors come with inbuilt alarms that go off whenever the protector stops functioning. With this feature, you can take a back seat and wait for the alarm to ring and immediately replace it with a new one.
