Are you tired of unwanted cellular signals invading your space or compromising your privacy? Say hello to the T-US-004 4 Bands 2G 3G Cellular Blocker Jammer with Car Charger (10W)—a powerhouse designed for high-intensity, long-term use. Priced at just $337.45, this cutting-edge device delivers seamless signal blocking for 2G and 3G networks, whether you’re indoors or on the move. With a coverage range of up to 30 meters and a versatile dual-mode power supply, the T-US-004 is your go-to solution for taking charge of your wireless environment.
Engineered for Excellence
The T-US-004 isn’t just another mainstream cell phone frequency jammer—it’s a precision tool built to perform. Unlike typical "band-mixing" jammers that struggle with signal overlap, this device features modular frequency isolation technology. Each of its four bands—CDMA (851-894 MHz), GSM (925-960 MHz), PCS (1920-1990 MHz), and 3G (2110-2170 MHz)—operates independently with its own cavity and RF path. This eliminates crosstalk and ensures powerful, consistent blocking across all targeted frequencies.
With a robust 10W total power output and a shielding radius of up to 30 meters (signal strength ≤ -75 dBm), the T-US-004 is perfect for small to medium-sized spaces. Whether you’re securing a meeting room, maintaining focus in a classroom, or ensuring privacy in a vehicle, this jammer delivers unmatched reliability.
Built to Last with Intelligent Design
Continuous operation is no challenge for the T-US-004. Designed for 7×24 hours of uninterrupted use, it features an intelligent temperature control system. Encased in a durable aluminum alloy shell, the device includes an automatic speed-control fan that activates and adjusts dynamically when temperatures rise. This prevents overheating, signal drift, or frequency reduction, ensuring stable performance you can depend on.
Weighing only 1.5 kg and measuring 26.5 x 11.5 x 5 cm, the T-US-004 is compact and portable. Its sleek black design, complete with four detachable antennas, blends functionality with style, making it easy to deploy anywhere.
Versatility at Your Fingertips
What makes the T-US-004 truly stand out is its dual-mode power supply. Use the AC 100-240V adapter for indoor setups or the included DC12V car charger for plug-and-play convenience in your vehicle. With a power consumption of just 36W and a 3A current, it’s energy-efficient yet powerful enough to handle any scenario.
Imagine this: You’re driving to a confidential meeting and need to block all cellular signals in your car—simply plug the T-US-004 into your cigarette lighter, and you’re set. Or perhaps you’re managing an exam hall where distractions must be eliminated—just position the device indoors, and let it work its magic.
Simple Setup, Instant Results
Getting started with the T-US-004 is effortless:
- Tighten the four marked antennas into their designated ports.
- Place the jammer in an optimal spot—ideally at a height of about 2 meters.
- Connect the power supply (AC for indoors or DC for vehicles).
- Watch it work automatically—no complicated settings required.
The front panel’s indicator lights (red, green, blue, and yellow) confirm that all four bands are actively blocked, giving you peace of mind at a glance.
