Today's capitalist society is filled with many electronic products that make use of AC adapters, e.g. digital cameras, cell phones, cd players, laptop, video game console, speakers, battery rechargers, and clocks.
Surprisingly, there is not much standardization in this department. Each product
comes with its own AC adapter (or worse, sold as a separate item), and other AC adapters, despite having the same voltage output, will not physically fit (according to radioshack).
A plethora of AC adapters can quickly accumulate within a household with each new purchase of electronics. To cut back on redunant hardwares and unnecessary expenditures, and to reduce the cost of each AC adapter by allowing greater competition, a government mandated AC adapter standard can help the consumers like it did when batteries, screws, nuts and bolts were standardized.

I wouldn't mess with Radio Shack if I were you. They are a powerful cartel of villains. With this idea, you're liable to wake up and find yourself dead, strangled with a cheap coaxial cable, your mouth stuffed full of rechargable NiCad batteries, and your genitals covered in alligator clips. |

[ninja] ouch! Well I think it's a good idea. If it reduces the number of dang cords in my house I'm for it. |
|
| |
Ummm - a tad ironic that I purchased my universal adapter from Radio Shack. |
|
| |
Ha, I forgot about that. I remember that all you have to do is to buy the right adaptaplug that fits between the product and the universal adapter. |

All devices list the voltage, plug size, and polarity on a label, usually on the bottom or back. You'd be surprised how many similar adapters there are. By the way, [link]. I (ahem) thought it was appropriate. |
|
| |
Hehe! [tong], mine is even older than that. All the plugs are built into the cord. |
|
| |
Well, I'm still going to need _alot_ of these adapters. They're powering many of the devices in my home. I can't unplug my cordless phone to plug in the cable modem, and then unplug it to plug in my computer speakers, can I? |

If there were one common adapter for all the items I needed, it would have to supply about 3 amps of power. It's a very large, floor-type adapter. I don't want (or want to pay for) 20 of these in my house. |

I have one with a switch to control the output |

One approach I've thought would be interesting would be a standard three-pin wall-wart connector. The third pin would be used to provide voltage feedback control to the power supply. Such a system would have some advantages, especially in cases where a device's voltage demand could vary. For example, a device that runs on a four-cell NiCd battery could operate itself on 4.8 volts but would use a higher voltage to charge the batteries. By switching a wall-wart supply between 4.8 volts and about 6 volts, the device could control battery charging without having to have bulky switching stuff on-board. |
