Description
This product does the opposite of our data blocker – it leaves the D+ and D- and ground (0V) lines untouched so that data can pass through, while blocking the 5V line which would normally provide power. It is useful for specialist applications such as some 3D printers where providing power results in undesirable effects.
Note that data transfer will not be possible with a power blocker in many cases, eg for smartphones, KVMs, USB sound cards etc. You can read through reviews on Amazon USA to get an idea of whether it will work for you.
This version supports USB 2.0 transfer. We do not offer a USB-C version since our testing shows it did not work with most devices.
This can also be purchased from Amazon UK here, and EU customers may purchase here.
