Mains Powered USB Wall Charger; with Real Time GSM Audio Listening

A great addition to the range of GSM live listening products is this fully functional USB Charger with GSM Listening capability.  Simply connect the USB plug into a mains wall socket to provide power to other USB devices (via USB cable) in the normal manner and also at any time dial the associated SIM card inside the plug to listen into the surrounding environment up to 25 feet away from where the USB plug is situated.

Unlimited standby time - no need for batteries or recharging thus providing long term audio surveillance.

As with all the GSM devices we offer there is no cackling interference and no humming noises associated with inferior devices.

Please Note: We will supply a pre-fitted SIM card however, if you purchase the optional Sound Detection feature which notifys your mobile phone when sound is detected then you will need to top-up the SIM card with credit (or any SIM card you use) in order to use the Sound Detection feature.


We appreciate some customers prefer to insert / remove a SIM card without using a screwdriver or other fiddly methods therefore, the SIM card slot is located at the side of the plug for easy access.


Supplied is a standard USB cable ideal for connecting to the USB plug whilst enhancing the authenticity.  You can of course use any USB cable with this product.


If you wish to record the audio that you hear through the GSM Double Plug Adapter then please consider the iPhone / Smartphone Mobile Call Recorder.

This product syncs with any mobile phone using Bluetooth so that the room environment that you are listening can be recorded onto the device.  It can also record and store both sides of a mobile phone conversation to the devices internal memory.

Simply enable Bluetooth on the Smartphone Call Recorder and enable Bluetooth on your mobile phone and sync both devices together. Now, when you call the USB Charger the call can be recorded.  Likewise, if you wish to make or receive any mobile phone call and record the call/s it is now possible.

The iPhone / Smartphone Recorder can be optionally purchased from the drop down menu above.

The USB GSM Listening Plug provides live audio monitoring of your home, office, portacabin, caravan etc for peace of mind when you are absent.  A consideration for the securirty conscious person.
