SZ Vodasafe VS-PJ18 High-Power Suitcase Portable Multi-Band Signal Jammer
SZ Vodasafe VS-PJ18 is a heavy-duty suitcase-type portable full-frequency signal jammer independently developed by SZ Vodasafe, rebranded from the original Vodasafe PJ18 model. It is a professional high-power wireless signal shielding solution built for confidential security scenarios requiring full-spectrum signal isolation. This unit integrates 18 independent RF jamming channels, delivering a total output power of 113W, and can simultaneously block mainstream wireless signals including 2G/3G/4G/5G cellular networks, dual-band Wi-Fi, multi-band GPS, LOJACK, VHF/UHF remote control signals, and RF remote frequency bands such as 315MHz & 433MHz.
The whole machine adopts a rugged portable hard suitcase housing design for convenient mobile deployment, with a built-in 24V high-capacity lithium battery to support standalone field operation without fixed mains power. Meanwhile, it reserves an external power interface to extend continuous working duration.
Customization service for drone defense enhanced version is available, which is equipped with 4–6 extra dedicated anti-UAV antennas to realize full interception of mainstream consumer drones like DJI Phantom 3/4 series and Inspire series.
The product shell is matte black engineering plastic with shockproof, dustproof and waterproof performance, adapting to complex outdoor and indoor harsh working environments, with a wide operating temperature range of -30℃ to 60℃. It comes with a complete set of supporting accessories for one-time unpacking and deployment, and enjoys a 1-year official factory warranty counted from the delivery date.
Core Frequency Band Coverage & Power Configuration
VS-PJ18 contains 18 fully separated jamming channels, each channel supports stepless power adjustment from maximum output to complete shutdown, allowing users to independently enable or disable specific frequency bands as needed without mutual interference between different signal modules. The detailed frequency coverage and single-channel average output power are as follows:

Channel 8 (4G 2600): 2500–2690MHz, 8W (39dBm), shields high-frequency 4G LTE global mainstream bands.
Channel 9 (VHF / LOJACK): 135–175MHz, 5W (37dBm), blocks VHF radio frequency and LOJACK vehicle tracking signals.
Channel 10 (GPS L1): 1570–1610MHz, 5W (37dBm), core GPS positioning signal shielding channel.
Channel 11 (RC 315): 315MHz, 5W (37dBm), interferes with 315MHz remote control signals for vehicles, alarms and small wireless devices.
Channel 12 (DCS / PCS): 1805–2000MHz, 8W (39dBm), blocks 2G DCS and PCS mobile communication bands.
Channel 13 (GSM / CDMA): 850–960MHz, 10W (40dBm), covers classic 2G GSM and CDMA cellular low-frequency bands.
Channel 14 (RC 433): 433MHz, 5W (37dBm), shields universal 433MHz industrial and civil remote control signals.
Channel 15 (Wi-Fi 2.4G / 4G 2300): 2300–2500MHz, 8W (39dBm), blocks 2.4GHz Wi-Fi and 2300MHz 4G supplementary bands.
Channel 16 (Wi-Fi 5.8G): 5500–5900MHz, 3W (35dBm), interferes with 5.8GHz high-speed wireless network signals.
Channel 17 (5G 3700): 3600–3900MHz, 5W (37dBm), covers extended 5G high-frequency communication bands.
Channel 18 (3G 2100): 2110–2180MHz, 8W (39dBm), shields global WCDMA 3G core frequency band.
The single-channel power output ranges from 3W to 10W, with a total aggregate power of 113W, realizing high-efficiency full-spectrum signal suppression.
Shielding Range Performance
Under standard signal strength environment (-75dBm reference signal), the effective shielding radius of VS-PJ18 ranges from 10 meters to 80 meters. The actual coverage distance will fluctuate based on local surrounding base station signal density, building wall structure, and wireless signal power in the site. It is worth noting that the effective shielding distance of low-frequency VHF and UHF signals is shorter than that of cellular mobile communication signals, which is determined by the propagation characteristics of radio waves.
Power Supply & Continuous Working Capacity
VS-PJ18 supports dual power supply modes for flexible indoor and outdoor use:
Built-in power system: Equipped with a built-in 24V 10Ah lithium battery pack, which can continuously work for 60–90 minutes (1.5 hours) under full-power operation. An LED status screen is reserved on the front panel to real-time display remaining battery power and charging status data, allowing operators to check power conditions at a glance. The machine also supports matching external extended batteries to extend working time for long-duration field tasks.
Mains power supply: Matched with an AC 110–220V universal power adapter, converting alternating current to DC24V to supply power for the host. The adapter supports 50/60Hz global grid frequency, compatible with power grids in most countries and regions worldwide. When connected to mains power, the built-in cooling system can run stably without power limit.
High-Efficiency Heat Dissipation System
Long-term full-power operation of high-power jamming modules will generate a large amount of heat, so VS-PJ18 is equipped with a professional active heat dissipation structure to avoid overheating failure:
High-density aluminum alloy integral radiator, which quickly conducts heat generated by each RF power amplifier module;
Three built-in high-speed silent cooling fans, which continuously circulate air inside the suitcase to take away heat;
The combined heat dissipation design ensures the machine can maintain stable full-power operation for a long time without thermal protection shutdown, greatly improving equipment reliability during long-time shielding tasks.
