Best Surge Protectors and UPS Battery Backups

Updated for 2026 — This article has been reviewed and updated with the latest recommendations.

A power surge can destroy hundreds or thousands of dollars worth of electronics in a fraction of a second. Lightning strikes, utility grid switching, and even large appliances cycling on and off create voltage spikes. A surge protector absorbs that spike before it reaches your equipment. A UPS does the same thing and adds a battery that keeps devices running during outages.

Most people plug their computer into a basic power strip and assume they are protected.

They are not. A power strip adds outlets. A surge protector adds protection. The difference matters.

Surge Protectors vs Power Strips vs UPS

Power strips are just extension cords with multiple outlets. No protection. Surge protectors include Metal Oxide Varistors (MOVs) that absorb excess voltage. Rated in joules. UPS battery backups include surge protection plus a battery for power outages.

Some also condition power to smooth out fluctuations.

Understanding Specs

Joule rating: Total surge energy the protector can absorb. Higher is better. 2,000+ for computers, 3,000+ for home offices. Clamping voltage: Voltage level that activates protection. Lower is better. 400V or less is good. Response time: Under 1 nanosecond is excellent.

When to Replace Your Surge Protector

Replace every three to five years, or immediately after a major surge event. Check the protection indicator light periodically. When the MOVs wear out, the protector becomes a regular power strip.

What Needs Protection

At minimum: computer, monitor, router, and modem on a surge protector. A UPS is worthwhile for computer and router if outages are common. Entertainment systems should be on a surge protector. Kitchen appliances and power tools generally do not need it.

Bottom Line

A quality surge protector is cheap insurance. A UPS adds battery backup for work continuity. The Tripp Lite and APC surge protectors provide excellent protection. The CyberPower CP1500AVRLCD is the best UPS for most home offices. The APC BE600M1 keeps internet running during outages for minimal cost. Protect your gear before something goes wrong, not after.
