Specifications
The Vodasafe P28 is built to excel in every technical aspect, ensuring consistent and powerful jamming capabilities across all bands. Below is a detailed breakdown of its specifications:

Unmatched Advantages: Why Choose SZ Vodasafe P28
The Vodasafe P28 stands out from conventional signal jammers with a range of innovative features and benefits, designed to meet the demands of modern civilian security and privacy needs:
1. Global First: 28-Band Portable Design
As the world's first portable 28-band jammer, the P28 covers more signal types than any other device in its class. It uniquely blocks FM radio and Wi-Fi 6E (the latest WiFi standard), ensuring it stays ahead of evolving wireless technology and addresses emerging civilian jamming needs.
2. Customizable Jamming with DIP Switch
The side-mounted DIP switch allows independent control of each band. Users can easily toggle bands on/off (default: all bands ON) without affecting other channels - perfect for civilian scenarios where only specific signals need to be blocked (e.g., disabling GPS jamming in areas where civilian navigation is required).
3. Versatile Power Options
With AC, car, and battery power support, the P28 is adaptable to any civilian environment:
AC Power: Ideal for fixed civilian locations like offices, meeting rooms, or museums.
Car Charger: Perfect for civilian in-vehicle security (prevents GPS tracking on private cars, trucks, or recreational boats).
Built-in Battery: Enables portable use in civilian areas without power access (e.g., outdoor events or temporary private security zones).
4. Advanced Cooling & Durability
The combination of 3 cooling fans and an aluminum alloy radiator ensures the device operates at a safe temperature (≤60°C) even during long hours of civilian use, preventing overheating and extending the product lifespan. The sturdy construction and compact design also make it resistant to minor impacts during civilian transport.
5. User-Friendly Features
LCD Display: Real-time monitoring of battery life, voltage, and current eliminates guesswork about device status for civilian users.
Omni Antennas: 2.0dBi gain antennas provide 360° jamming coverage, ensuring no blind spots in civilian spaces.
Nylon Cover & Safe Case: The included nylon cover protects the device during handheld civilian use, while the optional safe case offers secure storage and transportation for personal or corporate use.
6. Long-Lasting Battery
The 7.4V/12000mAh Ni-MH rechargeable battery supports up to 80 minutes of continuous civilian operation and can be recharged up to 500 times - a cost-effective and eco-friendly solution for long-term civilian use.
Applicable Scenarios: Where Civilian Security Meets Silence
The SZ Vodasafe P28 is designed to thrive in a wide range of civilian environments, providing tailored security and privacy solutions for both commercial and personal use:
Quiet & Confidential Civilian Spaces
Meeting/Conference Rooms: Eliminate mobile phone distractions and prevent unauthorized recording of confidential corporate discussions.
Museums/Galleries/Theatres: Maintain a quiet atmosphere for visitors and protect artworks/exhibits from signal interference in public cultural spaces.
Churches/Temples: Ensure a peaceful environment for worship without disruptions from phone calls or messages in religious venues.
Classrooms/Training Centers: Help students and trainees focus by blocking mobile and WiFi signals (where permitted by local civilian regulations).
Security-Critical Civilian Locations
Banks/Financial Institutions: Protect sensitive financial data from wireless eavesdropping or unauthorized signal-based attacks in civilian financial facilities.
Hospitals: (Note: Conduct field tests first!) Block non-essential signals to prevent interference with medical equipment, ensuring patient safety in civilian healthcare settings.
Factories/Industrial Zones: Prevent signal interference with machinery and protect proprietary production data in civilian manufacturing facilities.
Civilian Vehicle Security
Cars/Trucks/Buses/Boats: Block GPS tracking signals to prevent unauthorized monitoring of vehicle location, ideal for civilian fleet management or transport of high-value personal/corporate cargo.

Important Usage Notes: Ensure Safe & Effective Civilian Operation
To maximize the performance and lifespan of your SZ Vodasafe P28 for civilian use, please adhere to the following guidelines:
Antenna Installation: Always connect all antennas (one-by-one) before powering on the device. Incorrect or missing antenna connections will severely reduce jamming coverage and may damage the device.
Charging Precautions:
Charge the battery for at least 8 hours before first civilian use.
Turn off the power switch before charging. The charging indicator will glow RED (charging) and turn GREEN (fully charged).
Do not use the device while charging - this may cause overheating (up to 75°C) and damage the charger or jammer.
Temperature Control: If the device temperature exceeds 60°C, turn it off immediately and contact your local SZ Vodasafe agent for assistance.
Interference Avoidance: Keep the device away from civilian electronic devices (computers, notebooks, televisions, audio equipment, and AM/FM radios) when powered on to prevent signal interference.
Battery Maintenance: The Ni-MH battery has a lifespan of approximately 500 recharge cycles. If the battery no longer holds a charge, contact a local agent for replacement.
Regulatory Compliance: Ensure the use of the P28 complies with local laws and regulations regarding signal jamming for civilian purposes. SZ Vodasafe is not liable for improper use violating regional civilian rules.
