Earlier in 2016 I showed you how to create a little USB condom using a few simple components. Well I'm back with an updated version, which has a much cleaner design.

Like the previous version, it combines a full size male USB plug, with a USB female port. The 2 middle data pins from the components have been physically removed, meaning only power can travel through it.

You simply plug this in between your standard USB cables and ports, then you can charge or power your devices as usual.

This version now comes with a really tactile hard rubber grip, making it much less fiddly to use.

There's also a keychain clip on this, making it easy to carry with you, so you always have it when you need it.


As the name suggests, this is meant to protect your electronic devices so you can charge or power them safely in any USB port.

For example, it's potentially dangerous to charge your devices at a public charging port, like on a plane, train, at a library or school. If you don't know or trust the port, then there's a chance it could be doing shady things like syphoning your data, or installing malware.

It's worth noting that this won't work on iphone/ipad lightning connectors, but it should work fine for all other standard USB cables.

I've been carrying mine with my keys for the past year, and it has come in handy many times.


If you don't want to mess around making your own, you can pick one up at the NODE shop. I've made this batch by hand, and will post to most places around the world.

Alright, thanks for watching, and check back for more videos soon.
