Built for How Business Buys.
PortaPow are the original data blocking company, starting with our first model in 2009 and now offering the widest range of products including a variety of colors, connectors, and even a transparent 'Pure' USB-A version so you can look inside the blocker. See some of our other products below.
Which Data Blocker Do I Need?
Check the end of your cable that plugs into a charger (not the end which plugs into your device!) and match it to the image on the left, Most public chargers use a USB-A shape socket, so if your cable is also USB-A then you need our USB-A to A data blocker.
But if your cable is USB-C and you want to charge from a USB-A shape socket, then you need to also convert the shape to charge from public sockets. Our USB-A to C blocker does that.
There are now also many USB-C public chargers, if you'd like to charge from these then you need our USB-C to A blocker or our USB-C to C blocker depending on the shape of your cable's connector. See below for our full range.
