Protected by three granted U.S. utility patents

Charge Power. Block Data.

A patented switchable USB cable that physically disconnects the data lines while you charge — hardware protection against juice jacking, with a status light that shows your mode at a glance.

The problem

Public charging is convenient. It’s also a data port.

Every USB connector carries power and data. ‘Juice jacking’ is the risk that a compromised public port or borrowed cable uses those data lines to reach into your device. Attacks can be devastating and the FBI and FCC have both warned travelers about the risk — because a standard cable has no way to stop it.

Lions Cables is engineered with a built-in security feature that detects unauthorized or suspicious data activity. If a potential data intrusion is detected, the security feature automatically disables the cable, helping prevent further data transfer and protect the connected device.

The mechanism

Security you can hold - and see

Software can be fooled – in 2025, peer-reviewed “ChoiceJacking” research defeated the USB trust prompts on devices from eight vendors, including the top six by market share. Lions Cables protect at the physical layer: when the switch is off, the data lines simply aren’t connected.

Flip the switch, cut the data

A physical switch on the cable disconnects the data lines while power keeps flowing. Charge on the road - airport, hotel, rental car - without exposing your device.

See your protection

An illuminated status indicator shows the cable's mode in real time. Green means charge-only. You never have to guess whether data transfer is possible.

One cable for everything

Turn data back on when you actually want it - syncing, file transfer, CarPlay or Android Auto. No dongles to carry, lose, or forget.
