Expert Verdict: Kasa HS300 Smart Power Strip 6 Outlets + USB
Kasa HS300 Smart Power Strip 6 Outlets + USB
The HS300 earns its price through per-outlet energy monitoring and zero-hub setup – two features competitors routinely charge more for or omit entirely. The 15A shared limit rules out running multiple high-draw appliances, but for a home office or media shelf full of TVs, streaming sticks, and lamps, it handles the job cleanly. At this price, it's a straightforward buy.
Buying Guide
How to choose the smart power strip
Smart power strips let you control individual outlets remotely, schedule devices, and monitor energy usage from your phone. Before you buy, there are five decisions that will determine whether a strip actually fits your setup or ends up collecting dust behind a desk.
-
1
Count Your Outlets
Most smart power strips offer between 4 and 8 individually controlled outlets, plus 2 to 4 USB ports. Map out exactly how many devices you need to control separately, because buying a 4-outlet strip for a 6-device entertainment center means some plugs stay dumb.
-
2
Pick Your Smart Platform
Smart power strips run on Alexa, Google Home, HomeKit, or their own proprietary app, and mixing ecosystems creates friction fast. If you already own Alexa devices, confirm the strip carries the Works with Alexa badge rather than relying on a workaround integration.
-
3
Check the Amperage Rating
A strip rated at 15A total shared across all outlets will throttle if you plug in a space heater and a monitor simultaneously. For high-draw devices like gaming PCs or kitchen appliances, look for strips that state per-outlet amperage limits, not just a combined total.
-
4
Verify Surge Protection Rating
Surge protection is measured in joules, and strips below 1000 joules offer marginal protection for expensive electronics. A rating between 1500 and 2000 joules is a practical minimum if the strip is protecting a TV, gaming console, or desktop computer.
-
5
Review the Energy Monitoring Detail
Some strips show total wattage draw for the whole unit, while others report consumption per outlet in real time, which is the more useful feature for identifying energy-hungry devices. Check whether historical usage data is stored in the app or only displayed live, since stored data lets you track patterns over weeks rather than just the current moment.
How We Tested
We installed each of the five smart power strips in a home office environment and ran them continuously for three weeks, testing app control, energy monitoring accuracy, and outlet independence using a mix of desktop PCs, monitors, and small appliances.
- Per-outlet on/off response time via app
- Energy monitoring accuracy against a calibrated meter
- Surge protection joule rating and UL certification
- App setup time and Wi-Fi connection reliability
- USB charging output measured under full load
Frequently Asked Questions
Individual outlet control lets you schedule, monitor, and cut power to each device separately, which is essential if you want accurate per-device energy data or want to kill standby draw on a specific appliance without cutting everything else. Whole-strip control is simpler and cheaper but gives you only aggregate wattage readings, making it nearly useless for pinpointing energy hogs. If energy monitoring is a priority, pay the extra $10 – $20 for per-outlet switching.
If you're managing home office equipment or an entertainment center where you suspect high standby consumption, energy monitoring pays for itself by identifying which devices are drawing phantom load around the clock. Strips with monitoring typically cost $40 – $70 versus $20 – $35 for basic app-controlled models. For a single lamp or phone charger, the basic model is sufficient; for anything with multiple always-on electronics, the monitoring tier makes sense.
Outlet count matters less than outlet spacing – a 12-outlet strip with standard 1-inch spacing will still block half its ports if you're plugging in wall-wart adapters, while a 6-outlet strip with wide-spaced or rotating outlets can accommodate all six cleanly. Measure the plugs on your existing devices before buying, and prioritize strips that list plug spacing in millimeters or specifically call out 'wide-spaced' or 'transformer-friendly' layouts. More outlets on paper frequently means fewer usable outlets in practice.
Many smart power strips list a joule rating on the packaging – 900J or 2160J are common – but some budget models include a MOV (metal oxide varistor) component that degrades after absorbing one or two surges and provides no indication it has failed. A joule rating tells you the theoretical capacity, not whether the protection is still active; strips with a surge protection indicator light or automatic shutoff are the only reliable way to know the MOV is still functional. Buying a strip based on joule count alone without checking for a protection-status indicator is one of the most common oversights in this category.
Most smart power strips are rated for 15 amps at 120V, meaning the strip itself becomes the limiting factor even on a 20-amp circuit – running more than 1,800 watts continuously through a 15-amp strip risks tripping the internal breaker or causing heat buildup. Check the strip's amperage label on the housing rather than the outlet rating, and add up the wattage of everything plugged in at peak use to stay below that ceiling. Space heaters, air fryers, and hair dryers routinely exceed what any smart power strip is designed to handle safely.
The mechanical relay switches used for individual outlet control typically last 10,000 – 100,000 switching cycles depending on build quality, which translates to several years of normal use but can shorten significantly if you're automating frequent on/off schedules throughout the day. The surge protection component (MOV) is usually the first to degrade, often silently, after absorbing large spikes. Most manufacturers offer a one- to three-year warranty on the electronics, but few cover connected equipment damage unless the strip is specifically marketed as an equipment protection guarantee product.
