USB Extension Cable with Data/Charge Sync Switch

Your cell phone charges off of USB, but can you really trust that charging station at the airport? Now you can control when to allow data in or out of your device with this little USB extension cable. You can plug it onto the end of any USB data/sync cable you have: mini-USB, micro-USB, Apple Lightning, or any other proprietary type. Voila! Your cable's data lines can now be switched on or off.
