USB Data Blocker LATENIS – Safe Charging at Any Public USB Port
Juice Jacking Is Real – The USB Data Blocker LATENIS Eliminates the Risk
“Juice jacking” is the practice of using a compromised USB charging port or cable to steal data from or install malware on a connected device. Public USB charging stations — at airports, hotels, conference venues, cafés, and shopping centres — can be modified by attackers to exploit the data-transfer capability built into every standard USB connection.
The attack is invisible. You plug in to charge. The port delivers power as expected. But simultaneously, it can extract your contacts, photos, documents, authentication tokens, and session cookies — or silently install spyware that persists after you disconnect. The entire attack takes seconds.
The USB Data Blocker LATENIS eliminates this attack vector entirely. By physically removing the data pins from the USB connection while leaving only the power pins connected, the USB Data Blocker LATENIS makes data transfer physically impossible — regardless of what the charging station attempts. You charge safely. Your data stays yours.
USB Data Blocker LATENIS – Key Features
🔌 Data Pins Physically Removed
Standard USB connections use four pins: two for power (VBUS and GND) and two for data (D+ and D−). The USB Data Blocker LATENIS physically removes the D+ and D− connections. This is not a software block, not a firewall, and not a filter — the data pathway simply does not exist when the USB Data Blocker LATENIS is in use. No data can flow in either direction.
⚡ 100W Power Delivery Compatible
Removing the data pins does not limit charging speed in standard charging mode. The USB Data Blocker LATENIS supports USB Power Delivery up to 100W and Qualcomm Quick Charge up to 36W. Your LATENIS privacy phone charges at full speed — safely.
🔑 Keyring-Sized for Every Journey
The USB Data Blocker LATENIS measures just 25mm × 15mm × 8mm and weighs 5 grams. Attach it to your keyring, slip it in your travel bag, or keep it in your laptop case. It is available whenever you need a public USB port, with no setup required.
🏗️ Aluminium Body & Gold-Plated Connectors
The USB Data Blocker LATENIS is built from anodised aluminium with gold-plated USB connectors. This construction ensures reliable conductivity, resistance to corrosion, and durability through thousands of insertions and removals — it is a travel companion built to last.
💡 LED Charging Indicator
A discreet LED indicator on the USB Data Blocker LATENIS confirms that power is flowing to your device. You know immediately that you are charging safely — not being silently exploited.
🔄 USB-A and USB-C Versions
The USB Data Blocker LATENIS is available in two connector versions: USB-A (female) to USB-C (male) for standard wall sockets and older charging stations, and USB-C (female) to USB-C (male) for modern USB-C stations. Both versions provide identical data-blocking protection.
How the USB Data Blocker LATENIS Works
A standard USB cable contains four wires: VBUS (+5V power), GND (ground), D+ (data positive), and D− (data negative). Juice jacking attacks operate through the D+ and D− lines. To execute a successful attack, the USB station must have a physical data connection to your device.
The USB Data Blocker LATENIS is a pass-through adapter where the D+ and D− pins on the station-facing connector are not wired to the device-facing connector. The internal circuit connects only VBUS to VBUS and GND to GND. Plug the USB Data Blocker LATENIS into any USB port, then plug your charging cable into the USB Data Blocker LATENIS. Power flows freely. Data cannot.
This approach is more robust than software-level USB data blocking (such as “USB Restricted Mode” on iOS or USB charging-only mode on Android), because it operates at the physical layer and cannot be bypassed by any software exploit targeting the device’s USB controller.
Combined with a LATENIS privacy phone running GrapheneOS — which includes granular USB connection permissions — the USB Data Blocker LATENIS provides defence-in-depth against all known USB-based attack vectors.

Frequently Asked Questions – USB Data Blocker LATENIS
Will the USB Data Blocker LATENIS slow down my charging speed?
No. The USB Data Blocker LATENIS supports up to 100W USB Power Delivery and 36W Qualcomm Quick Charge. Charging speed is not limited by the data blocker itself — it is limited by the power output of the charging station. In our testing, devices charge at exactly the same speed with or without the USB Data Blocker LATENIS in line.
Does the USB Data Blocker LATENIS prevent all types of USB attacks?
The USB Data Blocker LATENIS prevents all attacks that require a data connection between the charging station and your device. This includes juice jacking, BadUSB attacks, and malware injection via USB. It does not protect against attacks delivered through the power lines (such as “power line” side-channel attacks, which are extremely rare and require sophisticated equipment). For comprehensive protection, combine the USB Data Blocker LATENIS with a LATENIS privacy phone running GrapheneOS, which provides additional USB connection controls.
Which version of the USB Data Blocker LATENIS do I need?
Choose based on the charging stations you most frequently use. If you mostly use traditional USB-A charging ports (the rectangular plugs found in older charging stations, hotel rooms, and aircraft), choose the USB-A (female) → USB-C (male) version. If you use modern USB-C-only charging stations, choose USB-C (female) → USB-C (male). Many travellers purchase both versions to ensure coverage in all situations.
Is juice jacking actually a widespread threat?
Documented juice jacking attacks have been confirmed in multiple countries. The FBI and US Cybersecurity & Infrastructure Security Agency (CISA) have both issued public advisories recommending the use of USB data blockers at public charging stations. The European Union Agency for Cybersecurity (ENISA) includes public USB charging station avoidance in its recommended security practices. The USB Data Blocker LATENIS addresses exactly the attack vector described in these advisories.
Can I use the USB Data Blocker LATENIS with wireless charging pads?
The USB Data Blocker LATENIS is designed for wired USB charging connections and is not used with Qi wireless charging pads. For wireless charging, no data connection is established — wireless charging pads are inherently data-isolated. Use the USB Data Blocker LATENIS specifically when you need to use a public wired USB charging port.
Legal Notice: The USB Data Blocker LATENIS is a passive hardware device designed to prevent USB data transfer. LATENIS makes no warranty that it will prevent all forms of cyberattack or data breach. Users are responsible for evaluating their individual security requirements. USB Power Delivery compatibility depends on the charging station’s supported protocols. “Juice jacking” references are based on publicly documented security research and government agency advisories.
