How it works
Protection at the physical layer — where software can't be fooled
Juice-jacking defenses that rely on software prompts depend on you tapping the right button every time. Lion Cables take the decision out of software entirely: if the data lines aren't connected, there's nothing to exploit.
- 01
Every USB cable carries power and data
Inside a standard USB cable, separate wires carry electrical current and data signals. Any port you plug into can, in principle, use the data wires — that's what makes public charging a security question in the first place.
- 02
The switch physically disconnects data
Lion Cables put a toggle on the cable itself. In protected mode the data lines are physically disconnected — not filtered, not managed by software, simply not connected. Power still flows at full charging capability, but there is no data path for anything to travel over.
- 03
The status light removes the guesswork
An illuminated indicator on the cable shows its mode in real time: protected (charge-only) or data-enabled. Security you can confirm with a glance, before you plug in — no app, no settings menu, no trusting a sticker.
- 04
Flip it back when you want data
Unlike charge-only cables or blocker dongles, the same Lion Cable syncs files, connects CarPlay or Android Auto, and moves photos when you choose to allow it. One cable covers both jobs — protection in public, full function at home.
Protected mode
Data lines physically disconnected. Charging works everywhere — airport kiosks, hotel lamps, rental cars, borrowed chargers — while your photos, messages, and credentials stay unreachable.
Data mode
You flipped the switch on purpose: sync, transfer files, connect to your car. The illuminated indicator makes the mode unmistakable, so data is never on by accident.
Designed for the ports you actually use
The patented switching design applies across USB cable types — past, present, and future connectors — so protection doesn't depend on which devices you own. Details on connector coverage will be published with launch specifications. USB types, explained →
