The first cord protector to be tested over 20,000 bends
I personally have never had a phone connector last longer than a few months before ripping and tearing. I have 3D printed parts that allow this cord to last longer, but it is an inevitability that the cord will eventually tear.
According to Echo Products, cables are not expected to last longer than a year. That is why they have tested theirs to withstand over 20,000 bends.
The stress and bends put on your cell phones from charging 1-2 times per day will bring down just about any cord. With kevlar braided cable and TensileTubing, you will not need to replace the IronWire until the new version of the cord is invented and used on cell phones.
How it was made
The first production prototype they tested out using a spring over the connector end, but they wanted something that had more strength.
The redesign saw them introducing an extended plastic tubing passing through the connector joint and over the cable. This was significantly tougher and allows for some flexibility to take away from the stress on the connector joints.
The final product is a silver kevlar and nylon braid with a 3cm extra tubing protection which passes right through the connector joint for maximum protection.
