It’s late, the lights are already out, and you realize you didn’t plug in your phone to charge. Avoid in-the-dark fumbling by using felt to give your charging cord a tactile right-side-up marker.
Some charging cords have distinct markings you can feel with your fingers–the USB symbol on the top side of many cords, for example, is imprinted deep enough to easily feel–other cords have no marking or markings that are so light as to be difficult to feel in the dark. Electronics and DIY blog Unpluggd shares a simple hack: attach a little felt disk, used for protecting tables tops from the bottom of decorative items, to the side that goes up. In the middle of the night you can feel the correct side and plug it in without a problem.
If you’re not a fan of putting a little fuzzy felt disk on the charger you could always substitute in something else that is equally as tactile, say, a triangle of skateboard grip tape. Hit up the link below for more photos.
