Our technical assessment

The EXTREMPOWER is consistently focused on maximum operating duration within our long-term GSM devices designed. Its particular strength therefore does not lie in the smallest possible dimensions, but in the exceptionally high battery capacity of 78,200 mAh. If a device is to remain operational for very long periods and regular recharging is not practical, this model offers a significant advantage over more compact GSM listening devices.

The design in the power bank style is technically sensible: the large battery can be housed in an everyday casing without the high capacity being immediately noticeable. For short-term applications or situations where minimal dimensions are crucial, smaller GSM models are the better choice. However, if the focus is on long-term operation, high energy reserve, and as little maintenance as possible, the EXTREMPOWER is among the most powerful solutions in this device class.

Typical application scenarios:

• Private investigations and investigative research – securing evidence, documenting conversations
• Observation of remote properties such as vacation homes or hunting lodges
• Monitoring of boats, yachts, or RVs during longer absences
• Securing depots, warehouses, or outposts
• Journalistic investigations that require covert audio recordings
