USB C Port Blockers 5 Pack, Stainless Steel Security Locks with Key
- STOPS JUICE JACKING: Physically seals USB-C ports so employees, visitors, and strangers cannot charge personal phones, sync thumb drives, or transfer data through your laptop, workstation, or kiosk without permission

- PROFESSIONAL AND PERSONAL USE: Trusted by IT professionals, business travelers, small business owners, and families, securing devices in offices, coworking spaces, reception desks, training rooms, and shared home computers

Secure Your Devices Against Juice Jacking and Data Theft
An employee plugs their personal phone into a company laptop to grab a quick charge. A stranger at a shared desk slips a thumb drive into an unattended workstation. A kid at home connects an unknown device to the family computer. Every open USB-C port is an invitation, and PortPlugs USB-C Port Blockers close it. Designed for offices, home setups, public environments, and everyday travel, these locks turn an open attack surface into a physically sealed port.
Durable SUS304 Stainless Steel, Built for Heat and Wear
High-strength SUS304 stainless steel with nickel plating resists corrosion, heat, and the daily wear that cracks plastic alternatives. The precision-engineered metal key engages the internal latch, releases the lock, and removes the blocker cleanly without scratching or damaging the port, avoiding the stripped-latch failures common in cheaper designs. RoHS compliant and designed for long-term use.
Universal USB-C and Thunderbolt Compatibility
PortPlugs fit standard USB-C and Thunderbolt 3 and 4 ports across MacBooks, Windows laptops, Chromebooks, tablets, gaming handhelds, and desktop workstations. Use them with confidence in offices, coworking spaces, reception desks, training rooms, hotels, coffee shops, and any public setting where your device might be left unattended.
Shoppers Often Ask
Does this prevent juice jacking? Yes, by physically blocking the port it stops both public-charging-station attacks on personal laptops and unauthorized personal-device charging on company computers. Does the key come with it? Yes, every 5-pack ships in a reusable pouch with one matching steel key included. Will it damage my laptop port? No, the SUS304 stainless steel body is sized to USB-C tolerances and the key-driven removal avoids the latch-stripping issue common with plastic blockers. Is this good for a small business? Yes, the 5-pack secures a primary workstation plus spares, with larger pack sizes available for bigger deployments.
