You know those little square black power transformers that come with nearly every new electronic you get? We call them “Wall Warts”. The problem is that they often don’t have written down on them which device it charges. That’s why every single new adapter that comes into Adam’s house gets a small label made for it, describing exactly what electronic thing it belongs to. These label makers can make very small labels (Adam puts his name on all camera equipment in unobtrusive spots) or larger and colorful labels depending on the make and model you want to invest in.
