The GSM Bug in Power Extension - USB Version - is a fully functioning power extension cord with an integrated GSM Bug module.

The power extension cord also offers USB charging docs in addition to the standard outlets. 

It is the same bug module as used in the bestselling Longlife 60URP GSM Pro K+, and Vario Pro K+. The power cord itself can be found on the European market, and comes in the original cable box, with the standard power cord user manual. Instructions on how to set up the device are available on this product page, below. 

The device delivers crisp sound in a 7-meter radius with a high-end omnidirectional Knowles microphone, which is as we found more than enough for home and office spaces. Moreover, it can be used in most warehouses in a specific location for audio monitoring.
The voice activation function offers further flexibility when using the device, as you can call in and listen, as well as get a call from the device once the audio is detected in the area. Because it is powered from the cord and does not have an internal battery, it offers unlimited listening time. 
As far as covert devices go, this one makes it virtually impossible to get spotted with the naked eye or by chance. There is no lid to be removed, or microphone to be seen. One would have to break or disassemble (everything is screwed in) the device before looking for the SIM cardholder or the hidden module. 
The device comes with the screws packed separately, which enables fast and easy access to the SIM card slot, and a faster installation process.
