POWER long-term GSM listening device

POWER GSM eavesdropping device – 10,000 mAh battery for covert operations

POWER GSM eavesdropping device combines compact dimensions with a significantly higher energy reserve than typical mini GSM modules. The integrated 10,000 mAh lithium battery enables up to 100 days standby or up to 50 days operating time in eavesdropping mode. Direct audio access is via the mobile network – a call is enough to hear the room acoustics live at the deployment site.

Your advantages for long-term operations:

• Worldwide audio access – über das GSM-Mobilfunknetz unabhängig von der Entfernung erreichbar
• Up to 100 days standby – hohe Energiereserve für längerfristige Anwendungen
• Sensitive microphone – akustische Erfassung in einem Bereich von ca. 8–12 Metern
• Unobtrusive power bank design – alltägliche Bauform mit zusätzlicher Ladefunktion
• Easy handling – Betrieb mit geeigneten handelsüblichen SIM-Karten
• Optional voice activation – automatischer Rückruf bei erkannter Geräuschaktivität

Our technical assessment

The POWER model represents a particularly interesting compromise between dimensions and battery capacity within our long-term GSM devices. With 10,000 mAh, it already has a significantly larger energy reserve than classic mini GSM listening devices, without reaching the dimensions of the particularly powerful HIGHPOWER or EXTREMPOWER models.

This makes the device particularly suitable for applications where regular recharging should be avoided, while still placing value on a comparatively compact and unobtrusive design. The power bank housing offers an additional practical advantage: the required battery capacity can be accommodated in an everyday device form without the housing appearing unusual.

When maximum operating time is the most important selection criterion, HIGHPOWER and especially EXTREMPOWER offer significantly more reserves with their larger batteries. For short-term operations where the smallest possible dimensions are crucial, compact mini GSM devices are more suitable. The POWER positions itself exactly between these two device classes and is therefore particularly interesting when long runtime, manageable size, and flexible placement are to be combined.

Typical application scenarios:

• Long-term acoustic control without permanent mains power supply
• Applications where regular recharging of a smaller battery device should be avoided
• Vacation properties, boats, motorhomes, or other temporarily unattended areas
• Depots, warehouses, or branches with existing mobile network reception
• Mobile applications where a large emergency power reserve is more important than minimal dimensions

Technical data:

• Dimensions: 80 × 80 × 25 mm
• Battery capacity: 10,000 mAh
• Standby time: up to 100 days
• Listening mode: up to 50 days
• Microphone range: approx. 8–12 m
• Spatial range: independent of distance via the mobile network
• GSM frequencies: 850/900/1800/1900 MHz
• Network standards: 2G, 3G

Scope of delivery:

• POWER long-term GSM transmitter
• USB charging cable
• User manual

POWER GSM eavesdropping device combines a high battery capacity with relatively compact dimensions. It is therefore particularly suitable for long-term applications where a small mini-module offers too little energy reserve, but the extreme runtimes and larger dimensions of an EXTREMPOWER model are not required.
