T-US-004 – 4 bands 2G 3G Cellular Blocker Jammer with Car Charger (10W)

Take a look at this 2G 3G Cellular Blocker Jammer designed for high-intensity, long-term use. It supports continuous 7×24 hours of uninterrupted operation, with a coverage range of up to 30 meters. The equipped car charger makes its mobile deployment more flexible than other fixed devices.

Unlike most “band-mixing” jammers on the market, the device uses modular frequency isolation technology internally. Each jammer channel is equipped with an independent cavity and RF path to prevent crosstalk, overlap or weakening of the 4 bands.

At the same time, the whole machine is equipped with an intelligent temperature control system, an integrated aluminum alloy shell and an automatic speed control fan. When the operating temperature reaches a certain threshold, the system automatically starts the cooling fan and dynamically adjusts the speed according to the temperature to avoid signal drift or frequency reduction due to overheating, and achieve stable output.

Usage demonstration:

• Tighten the 4 antennas in place (the interface is marked)
• Place in a suitable position
• Connect the power supply (or the vehicle power supply)
• The device works automatically, no settings are required

🔌 Power supply method

• Indoor use: supports AC100-240V wide voltage power input
• In-vehicle use: equipped with a DC12V cigarette lighter plug, plug and play

Working frequency band:

CDMA: 851-894 MHz

GSM: 925-960 MHz

PCS: 1920-1990 MHz

3G: 2110-2170 MHz

Additional information: This device mainly covers the 2G/3G frequency band and is suitable for scenarios that have not yet fully entered the 4G/5G area. But if you need it, we also provide upgraded models with optional coverage:

4G LTE (P-US-08)

5G (P-US-014-1)

Precautions

1. The interference range will be affected by the local environment (such as signal tower distance, wall thickness, etc.), which is a normal physical characteristic. Please deploy it reasonably according to the actual scenario.

2. When the device is working, please try to place it in a higher position (recommended height is about 2M) to optimize the shielding effect.

3. Do not place the device near electronic devices such as computers, TVs, speakers, radios, etc. to avoid accidental interference.

4. To avoid loss of device function, please keep away from metal materials as much as possible.
