The portable version is ideal for smaller spaces such as an office. If a mass event is planned, there is a risk that one of your employees is “cooperating” with competitors; you should stock up on a portable jammer. Its range is up to 40 meters. Even air temperatures down to -400C will not allow equipment to fail and unreliable persons to find out secret information;

Working frequency

Cell phone jammers by Jammer Master are multi-frequency. With their help, you can temporarily “disable” devices and gadgets operating in the GSM, DCS, 3G, 4G, wifi, and GPS. You can clarify information regarding a particular type of phone, or eavesdropping device, from the store’s consultants;


The portable jammer can be recharged or operated continuously from stationary sockets 110-220 V or a car charger 12-36 V. The stationary version works with a constant connection to a 220 V outlet.

Power surges in the range of 160-240 V will not disable the equipment and will not lead to the shutdown of the jammer.

Fact check for portable jammer

  • The distance between the jammer and the cell tower can affect the jamming result, especially for the low-power portable jammer. You can’t expect to jam the phone completely while staying next to the cell tower.
  • Wall thickness and cladding material can also affect the jamming result. If a portable jammer is intended for several rooms at once, the result will be worse in the most remote;
  • The pocket or portable jammer is not enough for a large office or conference room because most of them are low-power.
  • Battery charge (for portable versions). Planning a long meeting or a serious conversation? It is better to prepare for it in advance and charge the battery.
  • Each jammer is equipped with several antennas designed for a specific frequency range. For example, our portable cell phone jammers can also block wifi simultaneously. If all you want to jam is a mobile communication and leave the wifi signal, you should remove the antennas blocking wifi.
  • Signal jammers do not make any sounds themselves; the operation is silent. They do not interfere with washing machines or dishwashers. Even a laptop with a computer will not turn off unexpectedly. It will not be possible to go online or send an e-mail if the necessary frequencies are blocked.
