Do you panic about leaving a phone charger behind in a hotel room? Do your hands get clammy when you have a jumble of chargers cords in your carry-on bag, but can't find the right one? I solved the tangled cord problem by using colored twist ties, electrical tape, or sticky labels.
I save twist ties from bags of bread/bagels in a small ZipLoc bag in my silverware drawer in the kitchen. As I buy cell phones, I label the phone charger cables with a twist tie. My phone has a red twist tie while my husband's phone has a green one. My teen's charger cord is yellow while the tween's is blue. When we arrive at a hotel, I will unravel the charger cables we need, so the phone can be placed on the desk in the hotel room while charging. I use the twist tie to secure the remaining charger cable to prevent the phone from slipping to the floor. At the end of our trip, the charger cables are easy to spot because of the colored twist tie.
For larger charger cables, such as though for digital/video cameras and laptops, I use a piece of colored electrical tape or a sticky label. I buy electrical tape, which is about 0.5" wide and is red or blue. I write the name of the device on the label on the charger cable. Many laptop charger cables come with an attached velcro or plastic tie, which helps to prevent tangled cords in a carry-on bag.
