 In order to maximize customer convenience and cost, many of RadioShack's power conversion devices feature changeable tips called Adaptaplugs.
The image at right shows one of these plugs; explanations of the different parts can be seen by hovering the mouse over the image. Adaptaplugs can be described in several ways: by color, by letter, by the EIAJ plug type, and the dimensions of the barrel (ID and OD, or inner diameter and outer diameter). Occasionally, the barrel will also have an inner pin; this is indicated in the next-to-the-last column, "Other".
If you are not sure what plug size you need and the information is not available in the user's manual or reference information for your product, you should contact the device's manufacturer for assistance. Use of the incorrect size of plug can cause damage to the plug, the adapter and/or the attached device.
If you have a RadioShack adaptaplug and are not sure what size it is, you can look up the possible sizes by the color of the ring on our Adaptaplug Color Cross-reference Chart.
The chart below provides a cross-refererence to these various descriptions.
