The standard length for charging cables is 3 feet, but when I buy new cables I often choose long ones – at least 6 feet and often 10.
Because standard cables are often too short to be useful.
The 3-foot charging cable by our living room couch, for example, is good only for the person sitting right next to the outlet, and even then the cable stretches only to the armrest. If I try to move my iPhone to my lap, it comes unplugged.
So now I have long cables in the house, car, office and travel bag.
A long cable is especially handy when traveling, especially if you need to plug in at the airport or a coffee shop and there’s no outlet near your seat or table.
