Patented · Made to protect
The charging cable with an off-switch for your data.
Lion Cables are switchable charging cables that physically disconnect the data lines while you charge - hardware protection against juice jacking, with a status light that shows your mode at a glance.
One email when cables launch. Nothing else, no spam.

01 - 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 charger uses the data lines to reach into your device. Documented attacks in the wild are rare - but U.S. agencies have warned the public about the risk, because nothing in a standard cable stops it. Read the plain-English guide
02 - 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. Lion 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.
03 - The comparison
A cable - not another dongle to carry
| Capability | Data-blocker dongle | Charge-only cable | Lion Cable |
|---|---|---|---|
| Blocks data at public ports | Yes | Yes | Yes |
| Still syncs when you want it to | Only if you unplug it | Never | Yes - flip the switch |
| Extra piece to carry & lose | Yes | Yes (a second cable) | No |
| Shows protection status | No | No | Yes - illuminated indicator |
Full comparison, including when a simple dongle is the right tool: data blockers vs. switchable cables
04 - The record
Built on granted patents, not marketing claims
The switchable data/power design, the physical disconnection mechanism, and the status illuminator are covered by three granted U.S. utility patents - each one publicly verifiable.

When can I buy one, and what will it cost?
Cables are in final development - pre-launch, with no shipping date or price announced yet. The waitlist is how you hear first, and it's just a notification list: one email address, an email at launch. We'd rather publish tested specifications and a real date than promise either early.
