Product Description
Following the success of our Data Block USB cables launched in 2009, 1st Gen Data Blocker USB Adaptor released in 2013 and 2nd Gen ‘SmartCharge’ Data Blocker released in 2015, we’ve now launched our 3rd Gen range of models. Many alternatives claim to be 3rd or even 4th gen when they’re similar to our 1st or 2nd gen and lacking the feature which truly sets our blocker apart – the fact you can see for yourself that it is physically blocking data.
PortaPow is a UK based company with all our products designed in-house.
The only data blocker you can see working
PortaPow has the only data blocker where the two wires which carry data have been physically removed, so you can be sure it is working. You can see this for yourself just by looking at the male USB-A connector.
SmartCharge
A basic data blocker will send a fixed charging signal, which may result in slower charging. The PortaPow Data Blocker includes our SmartCharge chip which detects and sends the correct signal for your device, compatible with Apple, Universal or Samsung standards. This will prevent slowdown and fix charging issues in some cases – read the reviews for testimonials.
Visible Security
The two data wires have been physically removed from the USB-A connector. You can easily see this through the unique security window cut into the metal.
Laser Etching
‘NO DATA’ and ‘PortaPow’ have been laser etched into the USB-A connector for added confidence you’ve received a genuine PortaPow product.
Compact Size
Measuring just 43x18x11mm (1.7×0.7×0.4″), its a similar size to a cable’s USB connector so won’t block neighboring sockets. Uses 25% less plastic than previous models for a lower environmental impact.
Zero-waste Packaging
The two adaptors arrive in a single bag which can be reused as a no-frills resealable case for the blocker and/or other small parts. The internal size is 60x50mm.
Data Blockers Compared
The creator of the type of hacks that our products defend against has tested our product and many of our rivals. Search for “mg.lol data blocker teardown” to read the verdict.
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.
