The 3 Best Surge Protectors of 2025

This is not a comprehensive list of every surge protector we’ve tested. We’ve removed models that no longer meet our requirements or are discontinued.

The 12-outlet Anker 351 Power Strip performed dreadfully in our testing, offering no surge protection whatsoever.

The 12-outlet APC Performance SurgeArrest P12U2 has an auto-shutoff feature that kicks in only when the main (L-N) leg wears out. This means that if either of its other two legs (L-G or N-G) breaks down first, it will continue to send power to your devices, which could be unsafe.

Like our top pick, the 12-outlet Belkin BE112234-10 performed well in our surge tests and is UL listed. It also has surge-protection and ground/fault indicator lights, three telephone ports, two coaxial connectors, a long cord, a lifetime warranty, and a great joule rating. However, it lacks auto-shutoff capabilities, so you have to check the indicator lights regularly to know when the surge-protection components are worn out.

The 12-outlet Belkin SRA007p12tt6 has as many outlets as our top pick, and it also adds USB ports (two USB-A and one USB-C), has a higher joule rating (3,480 joules), and costs a bit less ($40 at this writing). However, it performed worse in our surge tests, it isn’t UL listed, it forgoes an auto-shutoff mechanism, and it lacks telephone and coaxial connectors.

Although the 12-outlet CyberPower P1004UC has as many outlets as our top pick and adds a USB-A port and USB-C port, we dismissed it because it shut down permanently after being zapped with 1,800 volts in our surge tests.

The 12-outlet Tripp Lite Protect It TLP128TTUSBB failed to measure up to our top pick during testing, letting more than twice as many volts slip through.

The 10-outlet Tripp Lite Protect It TLP1008TEL has many of the same key features as our top pick, but it has two fewer outlets and lets through more volts in our surge tests.

We tested the eight-outlet Elac Protek PB-82S, eight-outlet Furman PST-2+6, and 10-outlet Tripp Lite Isobar HT10DBS against our upgrade pick, but they don’t offer the same combination of surge protection, cord length, and rugged build as that model.

The seven-outlet Tripp Lite SUPER725B performed well in our surge tests. It’s also UL-listed, and it has an auto-shutoff feature, surge-protection and ground/fault indicator lights, a 25-foot cord, a lifetime warranty, and a great joule rating. However, it isn’t as compact as other contenders with fewer than eight outlets, and it has an awkward shape that doesn’t allow it to sit flat on the floor.

The six-outlet Amazon Basics SMD607, Belkin BP106000, and Belkin BSV602tt have twice as many outlets as our wall-mounted pick, and like that model they have two USB-A ports and can be safely mounted to a wall with screws. However, they all suffer from being less compact or having fewer safety certifications than that model.

We tested the cheapest surge protector we could find at a local Walmart, the six-outlet Hyper Tough PS682B_B, to see how it would fare against our top contenders, and it failed spectacularly in pretty much every way.

The six-outlet Tripp-Lite TLP66USBR has four USB ports—most other models have two at most—but we found that it offered less-than-stellar surge protection. Plus, its extendable USB-hub feature is hard to maneuver and not that useful.

The six-outlet Utilitech 78613 has a bulky, unappealing shape and a flimsier build quality than otherwise comparable models.

The nearly identical three-outlet CyberPower CSP300WUR1 and CyberPower P300WURC2 performed relatively well in our surge tests, blocking all but 282 and 226.8 volts, respectively, of the thousands we threw at them. However, they have a bit more bulk than our wall-mounted pick, and a shorter, one-year warranty.
