The proper way to wrap a Mac power cable Posted on Thursday, December 12th, 2013 at 7:18 am. PTWritten by Dave Mark Are you kidding me? All these years and I never knew that this was the way it should be done. Genius. Paulo Clayton O.OBRILLIANT gjgustav Just don’t bend the small wire too much. That will break it really fast. I’d modify that technique a bit to have the small wire come straight through and then wrap around. drkhrse definitely have frayed the small wire wrapping it tightly. they should really do something about the connection there. gjgustav Yep – they need a longer and much more more flexible strain relief. Though, I really wish they’d put magsafe at both ends. Then if you break it, you can just replace the wire for $10 – $20. Not the entire adapter. macyourday Don’t wrap it tightly. Not necessary. Mark Thomson It’s mind blowing, isn’t it! The question I now have is, was it deigned like that, or is it a happy accident? Darcy Fitzpatrick Happy accident.http://support.apple.com/kb/HT1630?viewlocale=en_US&locale=en_USThe sheer volume of don’ts on this thing should tell Apple they have a problem on their hands with these cables… Mark Thomson Good point! danvrussell I’ve modified the design slightly so 85W adapters don’t have strain on the back power converter tip. https://alpha.app.net/danv2/post/17181510/photo/1 Darcy Fitzpatrick Truth be told, I usually just stuff the cable, unwrapped, in my bag to avoid getting my hands covered in floor filth. I keep my home and office clean, but that cable still manages to get grimier and grimier as time goes by. macyourday You’re probably the only one here not destroying their cables. Mi55 Been doing this for years – and yes, you should leave a slack loop (relief) where the small wire comes out of the brick so it doesn’t bend too sharply. Quick and tidy! And geeky! Steven Fisher I just bought an adapter for both end points. When I upgraded my display, I ended up with a spare adapter… which I use with the flip plug. It goes in my bag. Doug Adams I hate to be the old fogey in the room, but I knew this. It used to be in the little “Hello” booklet you’d get with your notebook. macyourday That’s only ok if you unroll the cables in one direction. If the cables are allowed to fall off the adapter in the uni-directional loops that they appear to have been wound on, twists in the cable will build up over a relatively short period and will cause the shielding, the internal wires and joins at either end to weaken and fail. For unidentifiable reasons, people get OC about their stupid leads and end up destroying them (this includes earphones). For a start, you don’t need the fat power cable that comes with the power adapters. All that’s required is a twin core power lead with he “figure 8″ end (shaver/VHS/DVD etc). It takes up less space, is much cheaper, lighter and easier to replace if lost or damaged. This type of cable works in all apple power adapters (iPhone/pad as well) and gives you a very handy extra 2 metres or so reach. Having worked with audio/video/power leads in television and radio for 35 years, I was taught early on not to wind cables in one direction, unless of course it’s wound onto a drum or reel, as it will get twisted and fail. For shortish leads, less than 20-30 metres, they should be wound in a figure eight pattern to even out the stresses. This can actually be done as loops in the hand by making one ordinary loop, then an “opposite” or inside loop where the lead comes out from the inside of your new loop rather than the outside the way people usually bunch their cables. This will prevent the stresses on the cable that cause it to fail. For the laptop cable, gently folding it in half, then half again and sticking the loops through an elastic band on the power brick, taking care not to strain the join at the brick, should give a lifetime of trouble free use. I still have an undamaged five year old 85 watt adapter that is used every day. The elastic band/s also help stop scratches on the power brick. For people who work with mic or other long audio leads (or even power cables), this winding method allows you to throw the lead (one end) towards the desk or equipment without kinks or loops or having to lay it out loop by loop.
