Protect your data

SyncStop prevents accidental data exchange when your device is plugged into someone else’s computer or a public charging station. SyncStop achieves this by blocking the data pins on any USB cable and allowing only power to flow through. This minimizes opportunities to steal your data or install malware on your mobile device.

SyncStop is the 'cased' version of the original USB Condom. We listened and spent some time designing and manufacturing our own enclosure.

SyncStop works with any mobile device:

"So if you're often charging on the go, and you don't truly know whether a given port is safe or not, it's time to think about a [SyncStop]."


Many public locations now offer USB charging stations, but it's a trivial task to modify one of these to allow an attacker to access your data. [SyncStop] device cuts off access to the data transfer pins on the USB port, while still permitting access to the power supply.

Some phones may be more susceptible to data theft and malware than others, but what is certain is that by breaking the data connection, [SyncStop] removes all doubt.

The backstory...

We originally built the first version of SyncStop (called USB Condom) to scratch our own itch. We wanted to minimize risks of charging our mobile devices in public areas. In late 2013 we tweeted about our work and the next morning flooded with emails and calls; we realized we were on to something. Our first production run sold out in a few days and even spawned copycat devices.

As a small independent information security firm, we’ve realized that too often information security is limited to those with deep pockets. Syncstop is our small way of bringing data security to a device we can't live without.

We hope you enjoy using it.
