I’ve purchased a PowerCurl for every Mac laptop I’ve had over the past few years. I’ve always hated trying to coil up the adapter and power cord neatly since they stay the way I want for about .68 seconds before uncoiling into their natural state of complete disarray. While the PowerCurl isn’t the most svelte accessory, it keeps my power cord and adapter organized and I can put it exactly where I want without it uncoiling and ruining my attempts at keeping some semblance of order within my bag. If you’re looking for something to magically make your power adapter and cord take up less room, this is not it. The PowerCurl’s purpose is to keep it all organized and let you set the adapter upright to improve air flow around it to keep it cooler.Note that Quirky has “updated” the PowerCurl to a new design. I use quotation marks because I really don’t think it’s an update since the new design doesn’t seem to be any improvement over the original. The new design packs the adapter portion into a circular holder and you wrap the cord around that but from what I’ve seen and read online, it’s incredibly difficult to wrap the cord tightly enough so it stays put in the new version. I intentionally looked for the original version here on Amazon since I knew that it would work well for me given my previous experiences. I didn’t get the color I wanted (gray) and had to settle for blue instead, but I’m happy I could still get the original version at such a great price.The PowerCurl comes in multiple sizes to fit the different power adapter sizes that come with the different Apple laptop models. If you don’t know what adapter you have, just read the text printed on the adapter itself – you will see right there with your very own eyes which one you have so you can order the correct PowerCurl. There’s really no need to ask complete strangers on the internet which PowerCurl you need as long as you can pick up your own power adapter and read what it says.
