You have a tangle of chargers, a lamp nobody turns off, and a kid who leaves the TV on all night. A smart power strip sounds like the fix, but you are not sure it is worth the money, or whether you should just walk around unplugging things like your parents did.

Here is the honest answer up front: for some households a smart power strip earns its keep, and for plenty of others a plain $10 strip plus a little habit change does the same job for less. The question is which one you are.

The single biggest mistake buyers make is treating a smart power strip like a surge protector. It is not. Most smart strips are rated for a few hundred to about 1,800 watts total, and that ceiling is shared across every outlet. Plug a space heater, a hair dryer, or a microwave into one and you can trip the strip, trip the breaker, or in a bad case melt the housing. Owner reviews are full of people who learned this the hard way. Buy a smart strip for low-draw electronics, not for anything that makes heat.
How easy is it to find replacement parts and filters?
This is where smart strips quietly beat a lot of other gadgets, and it is worth understanding before you spend anything.
A smart power strip has almost no consumables. There is no filter to replace, no cartridge to reorder, no belt or brush to hunt down. The parts that can fail are the strip itself and, if you use one, the Wi-Fi plug modules. Those either work or they do not, and when they fail you replace the whole strip rather than a $30 filter. For a busy parent, that is genuinely appealing: nothing to remember to reorder every three months.
The flip side is repairability. Smart strips are sealed units. There is no user-serviceable fuse in most of them, and once the internal relay or the Wi-Fi radio dies, the strip is done. You cannot buy a replacement relay from the manufacturer. What you can usually find is the same model still in stock, because the popular brands keep their models on shelves for years. That is the real long-term play: buy a model from a brand that has been selling the same line for a while, so that if one dies in two years you can buy the identical thing again and your app, routines, and outlet layout all stay the same.
If replacement parts and filters matter to you, the honest comparison is this. A smart strip has zero filters and zero consumables. A robot vacuum, a humidifier, or a dehumidifier all have filters you will be reordering for as long as you own them. So on the specific question of "what will I have to keep buying," the smart strip is one of the lowest-maintenance purchases in the house.
What it actually costs
First year, all in, typically looks like this.
The strip itself usually runs somewhere in the $20 to $50 range depending on how many outlets it has and whether it includes energy monitoring. A single smart plug, if you would rather start small, is often $8 to $25.
Running cost is the part people forget. The strip itself draws a trickle, usually under 2 watts, which is a few dollars a year at most. But the point of the strip is to cut standby draw from the devices behind it. Televisions, game consoles, and cable boxes together can pull 10 to 30 watts while "off," which can add up to roughly $15 to $40 a year depending on your electric rate and how many devices you have. That is the savings you are chasing.
Consumables: none. No filters, no cartridges, nothing to reorder.
So a realistic first-year picture is $20 to $50 spent, and $15 to $40 potentially saved, meaning the strip pays for itself somewhere in the first year or two in a household with a real standby-load problem, and does not pay for itself at all in a household with two devices plugged in.
What you get for that money
You get scheduling and remote control. Lights and chargers on a timer, the kids' console off at 9 p.m. whether or not you are standing there, and the ability to kill a whole cluster of devices with one tap from your phone.
You get energy monitoring on some models, which is genuinely useful the first month. Seeing that a single old cable box burns more than your fridge is the kind of thing that changes habits. If you want to measure a specific device before committing, the P3 P4460 Kill A Watt EZ is the classic plug-in meter people use for exactly this, and it tells you whether a strip is even worth buying for your setup.
You also get voice control through Alexa or Google, which sounds like a gimmick until you are carrying a sleeping toddler and can turn off the living room with your voice.
For a simple single-outlet start, the Kasa Smart Plug HS103 is one of the most commonly recommended starter plugs, and the two-pack Kasa Smart Plug HS103P2 costs less per plug if you already know you want two. If you would rather stay inside Amazon's own ecosystem, the Amazon Smart Plug sets up in minutes with Alexa. Budget-minded buyers often look at the Wyze Plug and the Govee Smart Plug. If you want a wall-mounted, in-wall look rather than a plug hanging off the outlet, the Leviton Decora Smart Plug is a different form factor worth knowing about.
When it is NOT worth it
Be honest with yourself here, because most people who buy a smart strip did not need one.
Skip it if you have fewer than three devices clustered in one spot. The math does not work. A $30 strip to control a lamp and a phone charger is a $30 lamp timer with extra steps.
Skip it if the devices are high-draw. Heaters, irons, kettles, and anything with a heating element do not belong on a smart strip. If your problem is a cold room, the fix is a heater on its own circuit, not a strip. The Lasko 754200 Ceramic Heater and the Dreo Space Heater are both meant to plug directly into a wall outlet.
Skip it if nobody in the house will actually use the app. A smart strip that nobody schedules is just an expensive strip.
And skip it if your real problem is that you keep buying gadgets. The strip does not fix that.
The cheaper alternative
Two real options that cost less and solve most of the same problem.
The first is a plain mechanical timer, usually $8 to $15, which turns a lamp or a set of lights on and off on a dial. No app, no Wi-Fi, no account. For a single lamp or a holiday light string, this is the right answer and it will outlive most smart plugs.
The second is a basic switched power strip with a physical on/off button, typically $10 to $20. If your habit is simply "I want to kill everything at the TV at bedtime," a strip with a foot switch does that for a third of the price, and there is nothing to set up. Many households that buy a smart strip and then stop using the app would have been perfectly happy with one of these.
The bottom line
Yes, a smart power strip is worth it, but only under one condition: you have three or more low-draw devices clustered in one place, at least one of them draws standby power, and someone in the house will actually use schedules or voice control. Under those conditions it typically pays for itself within a year or two and has no filters or consumables to keep buying.
If any of those three is missing, no. Buy a $10 switched strip or a $12 mechanical timer, walk over, and unplug things. You will save the money and lose nothing.
Frequently Asked Questions
Can I plug a space heater into a smart power strip?
No. Most smart strips are rated for a few hundred to about 1,800 watts total across all outlets, and heaters can exceed that on their own. Plug heaters, irons, and kettles directly into a wall outlet.
Do smart power strips save money on electricity?
They can, if you have devices with real standby draw. Televisions, consoles, and cable boxes together often pull 10 to 30 watts while switched off, which can add up to roughly $15 to $40 a year. With only one or two small devices, the savings will not cover the strip.
Do smart power strips need replacement filters or parts?
No filters, and no consumables at all. The only thing that wears out is the strip itself, and it is a sealed unit that is not user-repairable, so plan to replace the whole strip if it fails.
