And you don’t have to wonder whether it’s still doing its job, because once its protection has worn out, it safely cuts the power, so you know it’s time to get a replacement. It offers great protection against household surges that come from other equipment in your home or fluctuations from the power company.

However, it features prominent LEDs indicating a wiring problem, and it has just as many AC outlets as our Trip Lite top pick. In our testing, it clamped down on surges as hard as the Trip Lite 12-Outlet did, and its joule rating is about 30% higher (meaning it’s designed to last longer, but that’s just an estimate).

The APC’s shorter (6-foot) cord means you’ll have a harder time reaching faraway outlets, but we think it’s still plenty long enough for most people. It offers two USB ports and six AC outlets in a round package that’s smaller than a dinner plate.

It has an auto-shutoff mechanism, making it one of the few three-outlet options we’ve found that will disconnect power when the surge protection wears out. It performed well compared with other small options we’ve tested, blocking almost as many volts as larger models.

The PST-8 actually let less voltage through in our tests than high-end series mode surge eliminators that can cost hundreds more. Collapse all To separate fact from fiction about surge protectors, we reached out to experts in multiple fields while writing the original version of this guide.

We emailed with Jack Lucknow, an insurance pro who has been in the industry since the 1960s, and got advice on what part homeowner’s and renter’s policies play in protecting your technology investments. There’s little reason for anyone to leave their office, den, or home theater unprotected, or to hang on to old, worn-out surge protectors.

And if your home is subject to frequent brownouts or blackouts, you might want to replace your surge protectors as often as every two years. If you have a cheap, basic power strip (or the kind of multiport adapter that plugs right into a wall outlet), it most likely never had worthwhile surge -protection capabilities to begin with.

But you should replace these subpar options as soon as possible and be thankful that they didn’t catch fire or damage your electronics (PDF). That’s why we suggest looking for a surge protector with an auto-shutoff feature, which stops the device from conveying power when the protection wears out.

They can also protect against occasional surges from your utility company and are especially worth having in areas with unreliable power grids. Finally, if you want to protect equipment that could be damaged by a sudden loss of power, a hard disk drive that’s susceptible to data corruption, or critical gear that can’t ever go down (such as a CPAP machine to treat sleep apnea), you shouldn’t be looking at a surge protector at all.

Photo: Sarah Loose started our research by scanning the top results on Amazon, Google Shopping, and retailers like Walmart and Home Depot, as well as the websites of well-known brands such as Trip Lite, Ac cell, and Welkin, to compile a list of models. For our top picks, we knew we wanted something heavy-duty for use with home theater gear and game consoles in a living room (or computer equipment in an office).

We also looked at smaller units designed for kitchen outlets or bedside tables, as well as series mode and hybrid models for people who want the highest level of surge defense. Otherwise, we required, at minimum, an indicator light that will notify you when items plugged into the unit are no longer protected against surges.

In a previous round of testing in 2017, our engineer dismantled each surge protector in order to assess the components and construction. Video: Lee Johnson the next phase of our reporting, we tested some claims each company made.

According to the Institute of Electrical and Electronics Engineers, no home would ever experience a power surge over 6,000 volts (PDF), and most don’t even come close. The major exception to this would be direct lightning strikes, but considering that a bolt means upwards of 1 billion volts, no home surge protector is going to save your TV from one of those.

He compared the thickness of the wiring, the size and arrangement of the Move, whether any filters or capacitors were incorporated into the designs, and the overall construction quality. For reputable brands selling surge protectors in the $15 to $50 range, the guts were so similar that the dissection yielded no useful information, so we haven’t torn down the models we’ve tested since.

To further demonstrate the importance of using a surge protector, Johnson subjected a (very old) Dell LCD monitor to a 5,000-volt surge, both with and without protection. In contrast, when he funneled 5,000 volts directly into the unprotected monitor, it promptly cried out in pain, never to turn on again.

The internal designs of the Surge (left) and ZeroS urge models (right) we tested in 2017 were very similar, including these sealed metal boxes. But when we tested several models previously (the Surge SA-15, the ZeroS urge 2R15W, and the Furman Power Station 8), we put them through the same paces as their less expensive and more common Bio-based counterparts.

We also tore apart each unit and found similar designs and construction, with only minor differences in the visible components. We’ve tested dozens of surge protectors and are confident that the Trip Lite 12-Outlet SurgeProtector (TLP1208TELTV) is the best one to use with typical living room or office equipment.

Photo: Sarah Soothe Trip Lite 12-Outlet also has dual coaxial connectors, so you can hook up your cable box, plus three telephone ports. If you’re setting up a media center with equipment that requires a coaxial or telephone connection, these extra ports are nice to have.

But since this type of surge protector commonly sits out of reach (behind a couch, desk, or TV stand) and is designed for more heavy-duty usage, we don’t think USB ports are all that important. Unlike with your run-of-the-mill power strips (or even the Hyper Tough surge protector we considered in a previous round of testing), its veneer seems built to stand up to most minor scratches and scuffs.

It’s compact enough to slide under a bed or entertainment center, and a set of holes on the back gives you the option to mount it on a baseboard. Its thick, rubberized, 8-foot cord is 2 feet longer than the one on the , making it more convenient to run underneath bookshelves and couches.

The joule rating tells you how much the surge protector can take before it’s worn out, so our top pick is unlikely to last as long as the APC model. It has just as many AC outlets as our pick, it recorded roughly the same average output and let-through voltage in our testing, and its joule rating is almost twice as high.

It lacks telephone and coaxial connectors, which might be an inconvenience if you want to hook up your landline phone, dial-up internet, or cable box through your surge protector. These aren’t super useful for a media center but are nice for a home office or anywhere you have devices that can charge directly over USB.

Like our top pick, the Power Air safely shuts down once it can no longer protect your electronics, so you’ll know when you need to replace it. And despite its smaller size, the Power Air was able to suppress the most common surges about as well as larger models.

Its 6-foot cord is thick, flexible, and durable, and its outlets are spaced generously around the top of the unit, giving you full access to all of them. Lastly, its blue and green LEDs (which let you know, respectively, if the unit is powered on and protective) are well-marked and clearly visible on top.

In our full guide to small power strips for travel, we recommend models with as many as four AC outlets and up to two USB ports. It has a three-prong plug, as well as a plastic rod that fits into the bottom hole of the second outlet, ensuring a snug connection.

Most people don’t need this degree of protection, but the Furman Power Station 8 (PST-8) offers the strongest surge protection of the dozens of models we’ve tested, besting even high-end series mode surge protectors that cost hundreds more. Instead of relying on standard Move to absorb the entire surge, Furman adds extra protection: Once a surge goes over 137 volts, the entire unit shuts down to protect itself and any connected equipment (switching the unit on and off resets it).

Any surge that gets through before the shutdown passes through a series of capacitors as well as a large inductor meant to filter the extra power. The large MOVE, similar to those found in less-expensive units, sacrifices only part of itself as a last resort after the filtering stage.

The Welkin Surplus USB Swivel Charger (BST300bg) was by far the worst performer in our latest round of testing, letting through more than 800 of the 5,000 volts we threw at it. The Trip Lite Sinecure used to be our also-great pick for light use and travel, but unlike our, it doesn’t have an auto-shutoff feature, nor does it have USB ports.

When we tested them in previous years, both performed worse than our current pick in terms of let-through voltage. We bought the cheapest surge protector we could find at a local Walmart (the Hyper Tough 6-Outlet PS682B_B) for a previous round of testing, and it failed spectacularly in pretty much every way.

Plus, our from Furman, which is less expensive than true series mode protection, provided similar performance in our tests. Always replace your surge protectors after any large event (such as a lightning strike down the block or multiple outages in rapid succession), and if you’re plugging in new gear, check each outlet for burn marks or any sign of damage.

If your protector delivers power even after its Move have failed, plan to replace it anytime you have a major electronics upgrade, or at least every three to five years. The extra connections and cord length of a surge protector also add resistance that can allow heat to build up, potentially catching fire or otherwise damaging the device.
