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 100% sure it is working. You can see this for yourself just by looking at the USB connector.



Visible Security

Visible Security




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, no other data blocker has this.

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.

Which Data Blocker Do I Need?

This depends on the shape of the cable you use to charge your device, and the shape of the socket you want to charge from. 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 just need our USB-A to A data blocker, which is the one on this page. This is the most common scenario.

But if your cable is USB-C, then you need to also convert the shape to charge from public sockets. Our USB-A to C blocker does that. See below for our full range.
