Review on Electop 2 Pack USB Cable with On/Off Switch - Ideal for Driving Recorder, LED Desk Lamp, USB Fan, LED Strips by Demetrius Young

If anyone does not understand what this is for, I decided to give a review. If you have a USB powered device that is always on when plugged in, you can use this to add a manual power switch. Plug it in between a power source (be it an outlet or another USB cable) and the device itself, and then you can flip the switch in one direction to cut power to the device (turn it off), or flip the switch. switch to the other side and turn on the device (by turning it on). This can be useful if your device doesn't have a power button or if you need to manually manage the device's power. For example, I have a USB powered lamp with an on/off switch that I find difficult to reach in normal use. So I now have a lamp connected to a USB extension cord, with that cord between the extension cord and the lamp itself. If I leave the lamp switch in the on position, I can now turn it on and off with the switch on that cord, which is right at my fingertips. So if you want to do something like that, this cable is perfect! There is nothing to say here about the evaluation of the product itself - it works exactly as it is written. The forks are good quality, not too tight and not too loose, and the derailleur itself is solid yet easy to squeeze, so no headaches. It just works. And as of this writing, you get 2 for $6, which is pretty cool. If I had to say negative I would say the cable is short but it is intended to be used as an intermediate cable so that is to be expected. If you need a little longer I would pair it with a cheap USB extension cable. It is also important to note that this cable is for POWER only. No data is transmitted via it, only electricity. So keep this in mind when buying - if you need data, this isn't what you need.
