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.

SmartChargeA 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 SecurityThe 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 SizeMeasuring just 43x18x11mm (1.7x0.7x0.4"), 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 PackagingThe 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 ComparedThe 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.

Yet you must avoid overexpecting. USB charging has become a surprisingly complex situation over the years, with various only partially-compatible standards vying for prominence. Given the complexity, the PortaPow manages to likely provide a.) charging instead of nothing and b.) for advanced devices sporting high-rate charge capability, some charge rate _between_ the maximum the device would negotiate with a compatible charger and the mere 500 mA of original USB.
To check the above, I selected a Quick Charge 2.0 compatible phone for which I already had various charge rate data and compared those data to observations using the PortaPow Data Blocker. With the phone starting somewhat below half charge, charge rates via a PortaPow Data Blocker from a "Smart 2.4 A" USB port and a Quick Charge 3.0 port were a bit below and a bit above 30 %pt/hr (percentage points per hour), respectively. Good, but of course less than the 56 %pt/hr I've observed with direct connection to a Quick Charge 2.0 charger. Charge rate through the PortaPow data blocker proved similar to wireless charging of the same phone.
For another view, I collected a range of Garmin GPS units and observed simple usability. Garmin Nuvi models tend to switch to data transfer mode when connected to anything that seems unlike a Garmin power cable. This prevents user operation unless one works around that tendency (some models will time out and restart in operation mode, the simplest workaround). With the PortaPow data blocker between a notebook computer and each Garmin, only the oldest, a Nuvi 200W, switched to data transfer mode; all the later models I checked simply continued operating as usual. So, if you want a handy way to operate your Garmin Nuvi GPS from external power without being in a vehicle, the PortaPow data blocker may do the job without the bulk of an additional Garmin-specific charger. You'll lack traffic reception, of course, unless using a smartphone for that.
Charging performance of Garmin Nuvi models through a Portapow Data Blocker may be more interesting. Recent models reported "Suspend" or "Unknown" as their input current limit setting, while an older model reported 1 A. Starting near half charge and operating your individual unit for a while via a PortaPow Data Blocker would be the way to assess whether it charges (adequately) or at least doesn't discharge while you're operating it.
I needed a way to prevent the rider from connecting to my car's radio.
This worked perfect!

Une mesure simple d’hygiène numérique.
Questo oggetto é privo dei contatti per la trasmissione dati, quindi una volta inserito nella presa usb e collegato a lui il cavo originale del telefono, verranno collegati solo i due contatti che servono a ricaricare il telefono.
Un semplice sistema che ci protegge.
