That "to a point" can be significant, though probably not for computer peripherals that need the supply connected all of the time. There are devices with an internal rechargeable battery that depend on the current limit of the wall wart. There is a danger of charging a battery so fast that it overheats and fails when a wall wart with too high a current limit is used. Yeah, I know that the current limit ought to be built into the device, but that takes two transistors and a resistor and that most important design criterion remains - cheap. And while I'm at it there are too many of those cylindrical connectors in the world. The plus and minus leads are often not specified and you may not know if a device needs positive on the center or the outside. There is also a pair, 3.2 mm comes to mind, where there are two different designs that have different diameters for the inside pin. If you have the wrong one it can seem to fit but the pin carefully fails to contact the inside sleeve of the mate. It's a good thing I don't have much hair on top or I would have pulled it all out the last time I got hit by that one. -- -> The US of A is getting pelloreid <- -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
