Surge protectors are one of those tech accessories that are profoundly unsexy, yet surprisingly important. Without getting too much into the jargon, these devices protect your electronics from a spike in electrical voltage during a power surge; something that happens more often than you might imagine. 

Plugging directly into a wall outlet, most models have several sockets so you can plug in and protect multiple devices at once. If you’d prefer to avoid a hefty bill to replace a fried phone, TV, or laptop (and who wouldn’t?), a surge protector is the way to go.

What to Look for in a Surge Protector

Surge protectors come in a variety of shapes and sizes with a seemingly-endless number of specifications and features. You’ll need to weigh up a few different aspects to find the right choice for your particular needs.

Joule Rating

A joule is a universal measurement for a unit of energy. Every surge protector comes with a joule rating that determines how much electrical energy it can absorb during a power surge.

In simple terms, the higher the joule rating of your surge protector, the more protection you get. Shoot for something with at least 600 joules of protection as your baseline, and the more the better.

Portability

If you’re a traveler, the portability of your gadgets is an essential factor. In this case, you’ll want a surge protector that’s compact, lightweight, and plugs directly into an outlet.

For home use, however, a larger-bodied surge protector is often better. It typically provides a greater level of protection, and provides extra leeway when using bulky plugs. In addition, a home surge protector often has a cord rather than plugging directly into the outlet, so you can place it inconspicuously behind or under furniture.

Number of Sockets

Think about what you’ll plug into the surge protector. Do you have just a phone and a laptop? Or do you need to plug in an entire home theater system? This will make a drastic impact on which surge protector you choose. For more convenience, look for options that combine several outlets with a few USB ports.

Power Strip vs. Surge Protector

The last piece of essential information is sorting out the confusion between a power strip and surge protector.

Power strips simply split one outlet into several, letting you connect multiple devices at once. Most (although not all) consumer surge protectors also split a single outlet, but with the added benefit of safeguarding anything plugged into them from a voltage surge.

So from small, travel-friendly devices to models ideal for the home office or living room, these are our picks for the best surge protectors of 2021.

The final touch to this surge protector is a six-foot cord, which gives you the added convenience of hiding it wherever you need.

Best Budget Surge Protector: Philips 6-Outlet Surge Protector

Philips 6-Outlet Extender Surge Protector, 900 Joules, 3-Prong, Space Saving Design, Protection Indicator LED Light, 1 Pack, Grey, SPP3461GR/37

Philips has a long history of making high-quality equipment, with offerings going back to the late 19th century, and the company’s 6-outlet surge protector is no different. Despite the pedigree, it’s an inexpensive device, and our pick for the best budget surge protector as a result.

With six outlets, good portability, and surge protection up to 900 joules, it has everything you need in one slim, low-cost package. This particular version doesn’t have USB sockets, but there are similar, slightly larger models that also include twoor four USB sockets if you need them.

This model comes comes in five colors to meet your personal tastes (white, black, coral, grey, and teal), and there’s a light on the top that lets you know when surge protection is active.

The only drawback to this device is the plastic stabilizing lug on the back. It’s useful, but using it requires there to be two three-prong outlets, one above the other. That’s not an unusual configuration in most hotels and offices, but it’s worth knowing before you buy.

Pros
  • Plenty of outlets, including models with USB ports
  • Several colors available
  • Light to tell you if surge protection is active
  • Inexpensive
Cons
  • Plugging in the stabilizing lug requires there to be two grounded outlets on top of each other

Best Travel Surge Protector: Accell Power Travel Surge Protector

Accell Power Travel Surge Protector - 3 Outlets, 2 USB Charging Ports (2.1A Output), Folding Plug - Black, 612 Joules, ETL Listed

When you need useful surge protection coupled with a lightweight design appropriate for travel, the Accell Power Travel Surge Protector is an excellent choice. Weighing just 6.4 ounces, this is one of the lightest surge protectors available. It fits easily in a small carry-on bag, helped by the fold-down plug on the top.

It has two USB outlets for phones and smaller electronics, and three outlets that for once are in intelligent locations: one on the front and one on each side. This ensures you can plug in bulkier adapters that often cause you to lose an outlet on other surge protectors.

There’s an LED light to let you know surge protection is active. Maximum protection levels aren’t as high as some other models, but are still adequate at 612 joules. If that’s causing a few second thoughts, don’t stress: Accell backs this product with a five-year limited warranty that provides $100,000 worth of protection if the device doesn’t deliver.

Pros
  • Small and lightweight
  • Light to tell you surge protection is active

Best Compact Surge Protector: Allocacoc PowerCube

USB Wall Plug, Allocacoc PowerCube |Original|, 4 Outlets and 2 USB Ports, Cell Phone Charger, Power Adapter, Surge Protection, Compact for Travel, Home and Office, Space Saving, ETL Certified

The search for a compact surge protector ends with the Allococac PowerCube.

As the name suggests, this surge protector is a simple cube design. Complete with four outlets and two USB ports, you can charge everything you need without taking up much in the way of valuable desk or suitcase space. It’s also pretty inconspicuous, and gives you the ability to plug devices in without a cumbersome housing or a lengthy power cord.

One of the most innovative features of the PowerCube is that multiple units are easily plugged into each other, giving you even more outlets if you desire. In addition, this surge protector also has an extension cord accessory (not included) that gives even better accessibility if the wall socket is behind furniture or otherwise hard to get to.

The only downside is a low 175-joule protection rating. On the bright side, this is still far better than plugging your electronics straight into the wall, but if maximum protection is a priority, you’ll likely need to pick another model.

If a compact and innovative power “strip” with some degree of surge protection is what you’re after, however, the PowerCube should be right near the top of your list.

Pros
  • Small and lightweight
  • Sensible design
  • Multiple units can be stacked together
  • Optional extension cord gives extra flexibility
Cons
  • Low amount of surge protection
