Cable Cord Cylinders
What exactly is that cylindrical lump at the end of your power cord? We want you to know that they are called ferrite chokes or cores. They come with magnetic iron oxide, which prevents high-frequency electromagnetic interference. If the phone is too close to a speaker, weird noses will be transmitted during the call. These features will prevent those interruptions from happening in the first place!

Apple Power Cord Wings
If you own a MacBook, there is a chance that you have always wondered why they added wings to the adapter. There is no need to worry about them. In reality, you can just pull them up and then wrap the cord all over them. This way, you can avoid making a mess out of your cord! What a nifty little feature.
