This simple Instructable describes protecting the iPhone power cord with shrink tubing.

Step 1: What You Are Trying To Prevent

The iPhone is a significant investment but the power cord is surprisingly vulnerable to kinks and tears. To protect against this I applied a two inch length of shrink tubing. This serves to reinforce the collar.
really useful tips! Thanks
What is this tubes?<br>Where can I find it ?
<p>You may make it bulkier :) with some hot melt glue under the shinking tube. </p><p>http://www.instructables.com/id/Make-custom-cables-with-hot-glue-and-shrinking-tub/</p>
<p>I missed that image</p>
<p>I always add a spring from a ballpoint pen to stabilize the cable end. Makes it sturdy and stable. (even against cat bites ;) )</p>
<p>what gauge tubing are you using? My yellow from a color coded multi-pak is no where near the correct size.</p>
<p>Am ready..</p>
Hyperlinks1. I don't think so. The duration of heat seems way too short.
<p>This seems like a much better solution than my 3d printed one! I would love to try this, but do I have to worry about the heat gun damaging the charger?</p>
I saw this the day after my girlfriend's power cord broke. Damn! I will buy some heatshrink tube today and make this.
I hope this works for you. Let me know.
Masterleo. Good tip. Thanks
Runswithwolves. Amazon stilocks it. But Harbor Freight and local home stores carry a lot
<p>mabe a great shop you could add to the instructable : </p><p>https://www.sparkfun.com/products/9353</p>
<p>It was also my idea great work for the instructables ! </p><p>I bought mine here : <br><a href="https://www.sparkfun.com/products/9353" rel="nofollow">https://www.sparkfun.com/products/9353</a></p>
<p>WHERE DOES ONE FIND THE THREE MENTIONED PRODUCTS, PLEASE?</p>
<p>I'm fairly sure you can stretch heatshrink so it will fit over larger objects (like the usb plug) and it will still shrink down. Just be careful not to tear it.</p><p>Good 'ible :)</p>
<p>Good information. I'm going to try that to see what the limits are.</p>
Thank you for sharing this. It is such a simple solution to something that has plagued me for years... Using materials that I already have in my shop. Thank you!
<p>Thanks for the feedback and I hope it helps.</p>
This is a great idea! I use sugru when they break, but I don't even use the Apple chargers a lot anymore. This is probably much better than sugru.
<p>Thank you for your comment! I've used Sugru for different things too. I love that stuff. Hopefully this will make using Apple cables a bit less onerous. </p>

<p>It comes in different shrink ratios, ie 2:1, 3:1 etc. May need a higher shrink ratio to get it to fit over the lightning connector yet still shrink down enough to fit the cable snugly. They also make shrink boots- similar product but one end is larger diameter so it could fit over the usb and still fit the cable. Haven't tried yet, but great idea.</p>
<p>Yes. That looks like it would fit well over the usb part. What an interesting looking product. Thanks</p>
I was trying to find a picture of a boot real quick to show what one looks like. Turns out that is just regular shrink tubing with one end 'shrunk', but you get the idea. A good place for the hobbyist to get electronic parts and hardware is digikey.com.
<p>I have thought of this years ago for my iPhone cable but the phone plug part and the USB plug part are too big. I have used the paint on &quot;electrical tape&quot; or Plasti-dip to coat the cable. <br>http://www.plastidip.com/home_solutions/Plasti_Dip</p>
<p>there was an interesting comment in this thread made by Wekiva about a product that looks almost like a usb slipcover. I thought that was a good solusion.</p>
<p>For plugs that are too big for the heat shrink to fit over you can use SUGRU as well. You use it like model clay and it turns overnight into flexible and durable plastic. </p>
<p>Sugru is awesome. I used it to fix my running watch. I love that stuff.</p>
<p>Nice work. One way to strain relief the collar. I'm familiar with shrink tubing but never thought about it. One thing I'm afraid of is you got to have the right size to fit over your plug first. If your tubing is too big it won't shrink down far enough to snugly fit your cable and by that time the heat will soften your cable might affect its integrity/characteristics. Just some thought.</p>
<p>Yes. Good point. With shrink tube assortment kits you are almost sure to find a diameter that is the best compromise. I think it makes sense to avoid using sources of heat that are either so prolonged or intense that they compromise the integrity of the cable.</p>
<p>I do that trick when they are a little damaged, good idea for prevention</p><p>I bought a set of shrink tubing of various sizes in the banggood.com and I think i will not spend them in all my life.</p>
<p>I'm with you on that. I have this big box of shrink tubes and sometimes wonder what it would look like if I just hit it all with the heat gun at one time.</p>
The only downside that i've seen using this technique, since i did this a few times in the past few years, for the exact same reasons (repairs, as well as preventative), is that the wires can sometimes start bending &amp; kinking at the end thats away from the pins/connecting end... Idk how to thwart that, if that starts happening, since i tend to coil up my cords &amp; put them in my pocket, possibly in comprimising positions.
<p>Perhaps if you stiffen the collar more by using two layers of tubing or putting something like a spring from a pen or even a hard collar like a conduit. I think something like a spring might be better because if it was a hard conduit you might just have the same problem a bit further up on the cord. </p>
<p>I'm unfamiliar with shrink tubing. Where do I buy it?</p>
If there's one around your area, there is even some decent stuff from Harbor Freight Tools, which has at least two different kinds, one being marine grade, where the inner insulation melts and oozes into the small areas where air would normally still be trapped (since it doesnt always (or isn't always able to) hug to whatever it is, w/an air/watertight seal
<p>This is a great suggestion. I didn't know about marine grade and I will definitely use this for these projects in the future. There is a Harbor Freight about 5 miles away from me. Thanks! This is what I love about Instructables,by the way. You get great comments from people that are familiar with their stuff.</p>
Any home improvement store like Lowe's or Home Depot
<p>I got mine here: http://www.amazon.com/gp/product/B000FIDTYG?psc=1&amp;redirect=true&amp;ref_=oh_aui_search_detailpage</p>
<p>Mouser Electronics (Mouser.com) has some great adhesive lined shrink that grips awesome - EPS-300 series by 3M specialty. and choose diameter as needed, 1 tip using needle nose you can stretch open tubing further before heating if needed </p>
<p>Nice. A lot of people have asked this and this is a good suggestion.</p>
<p>Thank you!!!</p>
<p>All of my chargers split at the point of connection to the plug. I have been using tape by Gorilla. This sound better. Thanks.</p>
<p>Gorilla tape seems also a good solution but this might ultimately look a bit neater. Good idea</p>
<p>I've also used shrink wrap tubing to repair the &quot;rubber ducky&quot; antenna on a portable 2-way radio. </p>
<p>Brilliant. </p>
<p>Thank you, this was very helpful Grunambulax.</p>
<p>Hey. Thanks!</p>
