ELECTOP 2 Pack Male to Female USB Cable with On/Off Switch, USB Extension Inline Rocker Switch for Driving Recorder, LED Desk Lamp, USB Fan, LED Strips

Easy plug an play, works great with my fish aquarium lights

I didn't even know these existed until describing what I needed in the search bar. Very pleased to find exactly what I was looking forI immediately plugged one into the line controlling my gaming console fans and it worked perfectly. No more plugging and unplugging the power cord. The bonus is that you get 2. Great product !

In case anyone is confused what this is for, I figured I would go ahead and leave a review.If you have a USB powered device that is always on when plugged in, you can use this to add a manual on/off switch for the power. Plug this in between the power source (whether that be an outlet or another USB cable), and the device itself, and then you can flip the switch one way to interrupt the power going to the device (turning it off), or flip the switch the other way and allow the power to go to the device (turning it on).This can be handy if your device doesn't have a power switch, or if you otherwise need to control power to the device more manually.In my case, I have a USB powered lamp that has an on/off switch that is difficult for me to reach in normal usage. So now I have the lamp attached to a USB extension cable, with this cable in between the extension cable and the lamp itself. Leaving the lamp's switch in the "on" position, I can now turn it on and off via the switch on this cable instead, which is right at my fingertips. So if you're looking to do something like that, this cable is perfect!As for a review of the specific product itself, there's not too much to say - it does exactly as it says. The plugs are good quality, not too tight or too loose, and the switch itself is sturdy, but easy to press, so no headaches there. It just works. And, as of this writing, you get 2 for $6, which is pretty cool.If I had to say a negative, it would be that the cable is short, but it's meant to be an intermediate cable, so that's to be expected. If you need something longer, I would pair this with a cheap USB extension cable.Also, an important thing to note about this cable - it is strictly for POWER. Data does not transfer through it - only power. So please be aware of that when purchasing - if you need data, this isn't what you need.

it works just as i’d hoped. but there are some odd design choices that make it less than ideal. 1: the switch box itself doesn’t lay flat. it’s curved upwards for some reason on the underside - so it doesn’t sit flat on any surface giving it a wobble. plus if you planned on affixing it to a wall or desk with two sided mounting tape - it won’t stick properly because that requires a flat surface. if this is something you planned on doing, i’d look for one that has a flat bottom instead. 2: it also has very very short cords…so I had to also get a usb extension cord so i could plug into wall outlet. i think it was designed to be plugged into a laptop or docking station - definitely needs other elements to make it convenient. it’s just one piece in a multi part solution.

Purchased these for a USB lamp I bought, that didn't come with a power switch. These work great and solved the issue. They are well made and priced right.

I love this concept! I use a rechargeable lamp on my deck table at my off-grid cabin. But it is getting to be summer and the mosquitos are getting active. I have a few USB mosquito repeller and they work pretty good. But once you plug them in, they stay on constantly. The chemical pad that you insert only last for 4 hours or so, and it doesn't fit into the recessed USB power bank built into the lamp. So I was looking for a short USB extension when I found this. I used some double sided tape to attach the repeller to the top of the lamp and I can just use the switch in the extension to turn it off or on without unplugging anything. It works great! I will be using the second one for a USB fan that I have in the cabin near my bed.

This was purchased to control a string of USB LED lights, which are currently plugged in directly. It did not work. Maybe it's something to do with the power they can pass through? I'd like to know, as I'd like to get a switch that would work.

I have a number of USB powered devices that require occasional power down/poer up resets. These devices eliminate that risk of damage at the often fragile small USB connections into the devices, Note that the cords of these switches are relatively short, but I find that good since I did not want to add cable length.
