NO HEADLINE
Dear Heloise: Through the years, we have purchased many rechargeable or battery appliances and machinery that come with AC adapters. Many have become separated from the device they belong with.
I realize now that I should have labeled the adapters. I do have a universal adapter with a variety of different plug ends. It helps if I cannot find the matching adapter. However, it does not solve the problem of what to do with the mismatched adapters. – Joan Sarver, Lake Forest, Calif.
All you can do is try to match the adapter with the right device and put orphaned adapters in the garage-sale box. – Heloise
