Easy setup and just works
I was skeptical when reading about this unit. I set it up as soon as I received and it was really simple and straightforward. Added to Apple Homekit and Google Home quickly and without issues. It just works. The only thing I would change would be to have all 6 outlets WiFi enabled instead of just 3.

It really works!
I’m always afraid I can’t get stuff like this to connect, but I set it up fast and it works great! I like the night light feature an the fact that you can control 3 of the outlets individually (plus the usb??, not sure what to do with that).

Modern designe works well.
I recently purchased this item and loved it! The design is excellent, itâs easy to set up, and it looks very pretty. I especially love the built-in night lightâitâs a great feature. However, I didnât pay close enough attention to the description, which clearly states that it includes 3 individual smart plugs, not a set of 3 with two smart plugs each as I had initially assumed. This misunderstanding was my fault, but please note that the other three outlets on the right are regular plugs. Having only 3 smart plugs does make the product feel a bit expensive compared to other similar options.

Provides Automation, Tames a Crowded Outlet, and More!
I got started with home automation last year after went shopping for a conventional lamp timer and found that when purchased in multi-packs, TP-Link Kasa smart plugs actually cost less apiece. I came to appreciate the relative ease of use, versatility and accuracy of the smart plugs, so when the need arose for another timer of some sort, I went shopping for more smart plugs, either Kasa or Tapo, since both work with the Tapo app on my phone. That’s when Amazon’s AI offered what turned out to be a brilliant suggestion – this smart six-outlet extender, with 3 smart plugs, smart USB charge ports and even a night light. It cost more than I had originally planned to spend, but the moment I saw it, I started thinking about the crowded outlet next to my bed, where I had a couple of outlet splitters to accommodate a window fan, an air conditioner, a cell phone charger and more. I thought of how nice it would be to lose the flimsy outlet splitters, tame all those plugs, free up the smartphone wall wart, provide a little nighttime safety when it gets dark outside before I have a chance to run upstairs and turn the lights on, and save some money by having some of those items on timers. I already had one smart plug in that outlet, and that smart plug would go where I originally thought to put the new timer. This turned out to be a terrific plan. Some of the published specifications are a bit vague, though, so part of what I hope to accomplish in this review is to answer some of the questions that I could only get answered by buying my outlet extender.Let’s start with how this extender fastens to the outlet. I do recommend that you fasten it to the outlet, if at all possible, because the extender is large and relatively heavy, and with up to six typical electrical appliances plus USB cables plugged in, there will be a fair amount of force trying to pull this extender out of the wall outlet. If you have a standard wall outlet, the most secure way to install the extender is to use the provided replacement for the center screw that holds the outlet cover on. If you have a Decora style outlet, you will have to rely on the provided ground stud, which is removable and adjustable so you can make it reach the second outlet’s ground hole.Each smart plug/device on this outlet extender can be controlled and scheduled separately in the Tapo app, so you can automate up to 7 devices. Three standard electrical outlets on one side of the extender are smart, all three USB ports (two USB type A, one USB type C) are smart, and the night light is smart. Note that the USB ports are controlled together; you can schedule them separately from the smart plugs and the night light, but all three USB ports go on and off together; you can’t program them separately. The remaining three standard outlets, on the opposite side of the extender, are always-on. Everything on this extender is protected against surges. The smart outlets have manual switch buttons that let you turn them on or off at unscheduled times.The smart plugs in this extender are even smarter than the individual Kasa smart plugs that I bought last year. For example, my Kasa smart plugs can be set to go on or off up to 59 minutes before or after sunrise or sunset. The smart plugs, USB ports and night light on this extender can be scheduled to go on or off up to 5 hours and 59 minutes before or after sunrise or sunset. That can be very convenient for fine-tuning control of appliances that you want to go on or off based on when it gets light in the morning or dark in the evening. The extender gets the time of day, as well as the time of sunrise and sunset, from TP-Link’s Tapo cloud on the Internet, which presumably determines this based on the location of your cell phone at the time you set your Kasa and Tapo devices up.The USB ports support fast charging at up to 18W for devices that support it. That should be compatible with most cell phones, tablets and other small USB-powered items, but it will not charge your USB-C charged laptop.The night light is the most interesting, as well as the trickiest, to program. As the specifications say, you can set the night light to switch on at dusk and off at dawn, based on the ambient light level in the room, and you can specify what that ambient light level is, anywhere from 0 lux (completely dark) to 160 lux. You can also schedule when the night light will go on and off, and you can base that schedule on specific times or base it on sunrise and sunset (the exact time of sunrise and sunset, or up to 5 hours and 59 minutes before or after). You can also set the brightness level of the night light for each block of time that it’s on. However, you cannot mix the dawn/dusk sensor control of the night light with scheduling. If you want to mix those functionalities, use the scheduling feature instead of the Smart Control feature (setting a schedule will automatically disable the Smart Control feature), and schedule on and off times based on sunrise and sunset, along with any other times you want your night light to be on or off. I made use of all this as follows: I set my night light to go on at sunset at 100% brightness, off when my wife usually goes to sleep, on at 25% brightness a little later, when I usually start getting ready for bed, I turn it off manually (with with the app) when I get into bed, on at 100% when my alarm sounds in the morning, and off about an hour later.The outlet extender is rated at up to 1850W, which is the maximum draw of a 15A wall outlet. It should be able to control an air conditioner or a space heater, but those are high-draw devices, so be judicious. A 500 BTU room air conditioner can draw 720W all by itself, and might spike a little higher when the compressor kicks in, so I wouldn’t recommend trying to control more than one such high-draw appliance with this outlet extender.Finally, a few shortcomings:- As mentioned above, there are manual override buttons for the three smart outlets, but none for the USB ports and the night light. I really wish there was one for the night light, as it’s a bit inconvenient to turn the night light off with the app.- There are white LEDs next to each programmable item on the extender – the three smart outlets and the USB ports – although not next to the night light, because that IS a light. It would be nice if those could be set to shut off when the room is dark, as these LEDs are rather bright and may make it difficult for some people to sleep. The extender already has an ambient light sensor for the night light, so it shouldn’t be that hard to add this feature.- The outlets are spaced 1.57″ apart, 3 on one side and 3 on the other, in perfect symmetry, and that is a potential problem. Power bricks are insidious, but they’re part of everybody’s life in 2024. Alas, there is no standard for their size, shape and plug orientation, so even with the relatively wide spacing, a long, thin or bulky power brick may still block an outlet adjacent to the one it’s plugged into. It might help if the outlet orientation and placement could be varied or staggered a bit.However, these are very minor shortcomings, at least for me. I’m very happy with my outlet extender, and I’m eyeing another one for a living room outlet that could use some taming.

I Like It
Itâs a pretty useful device. Previously I had a power strip with a couple devices plugged into smart plugs. This allowed me to simplify those connections and clean up my wiring. I didnât know the USB connections were smart controlled also which was a nice surprise. It would be even better if those could be individually controlled which would add some flexibility to my connections but itâs not a huge deal. Setup was quick and easy with no issues adding it to Apple Home.

Soooo much better than a power strip
This nifty little gadget offers lots of control in a small package, and I love that I can turn off the USB ports!A few months ago, I bought some Kasa smart plugs. I’m kinda paranoid about things like forgetting to unplug the toaster, like it’s going to turn itself on and burn the place down while I’m at work. Smart plugs ease that anxiety, but they also make a lot of other things much simpler. I soon had smart plugs controlling lamps and fans through Alexa and running my little tabletop dehumidifiers on a schedule. But when I found yet another use for smart plugs, I ran into a little problem. Even Kasa Mini smartplugs are bulky, and with as many (low-power) things as I have plugged in, there just wasn’t room to smarten-up any more devices. So I went looking for a power strip with individually controlled outlets, and that’s when I came across this Tapo outlet extender. It solved all my problems at once!First, it’s easy to anchor this directly to the outlet with the included screw, so no risk of knocking it loose or having a couple of heavy plugs slowly pull it out. The 6 outlets on it are sideways and widely spaced, which made it easy to plug in two 15w square-ish adapters right next to each other. Of those 6 outlets, only 3 are smart, but that’s exactly what I needed. Plus, the 3 USB ports on the side (2 USB-A & 1 USB-C) are also smart, which isn’t too common with devices like this one. THat was actually a huge selling point for me, since one of the things I hate to leave on all the time is my phone charger. Now I can skip the brick, plug it directly into the USB-C, and I don’t have to unplug it to turn it off.Everything is controlled through the Tapo app, which I already use for some of my wifi cameras. Set-up was simple, and connectivity has been great. When I first set up my little individual Kasa smart plugs, it took 2 or 3 tries each to get them paired and connected, but I had no such problems with this Tapo device. And it certainly doesn’t hurt that the Alexa app was quick to recognize it.Overall, this is an awesome device. I love having more smart plugs without all the bulk, and being able to control the USB ports is awesome. I was able to ditch the big power strip and plug in and control everything I need to without bigger plugs overlapping some of the outlets. This outlet extender was exactly the solution I needed.

Soy cliente de la marca TP-Link y muy satisfecho con ella, pero a la vez exigente, tengo red de malla Deco y varios dispositivos Kasa, en esta ocasión tuve una pequeña dificultad al configurar el enchufe tapo por medio de la app de tapo ya que no se podia conectar a mi red Deco, solo lo intente una vez y al realizarlo por la app de Deco se instalo a la primera, que paso no sé pero lo bueno es que hay alternativas.El enchufe es excelente, salvo la luz noctura que al configurar el modo de control inteligente hay veces que se prenden aunque el nivel ambiental en Lux es mayor al nivel de activación configurado, todo lo demas funciona de manera normal para la calidad de la marca, algo que se podria mejorar es que se habilite el poder controlar todas las funciones desde la app de Deco ya que por el momento solo esta habilitada desde la app de Tapo, lo cual es molesto estarse teniendo que cambiar de applicacion.
