What I really like about these colorful little charging blocks is that they are a way for people to know “that's not mine”. My mom takes her charger that came with her iPhone and a cable with her every time she is at dialysis. When she is done, her tech for the day puts her stuff away in her backpack on her wheelchair. When she got home, her charging block and the cable weren't in the backpack. She called dialysis, told them that her tech didn't get her charger and cable in her bag, and would they see if it was back by her seat. They found out! and put it in the reception office for the next time mom had her next appt. When mom got to the clinic, her cable was there but the block was gone. With it being all white there wouldn't be any positive way of proving the charging cube was hers. This is why I bought her these colored charging cubes. No one else has a colored charging cube in that building!!! It's a definite way to prove it belongs to her. They work great. Another plus is that they don't take up a lot of room in her purse or backpack.
