AC Adapter Voltage Issue

[MC]

I have an AC Adapter that lets you select voltage from 3-12 in 1.5
increments. The problem is some of my devices (actually, the adapter
tha came with them) call for 5 volts. Can I safely use 4.5 or 6? I
generally travel with 3 or 4 original AC Adapters and am trying to
carry only 1.

Most "5 volt" devices will work on 4.5 volts. If the device runs from alkaline
batteries, it either uses 3 (4.5 volts) or 4 (6 volts). If the device has a
rechargeable battery, you probably should use the original adapter/charger.

Depends on what the device is that needs 5VDC. If it's a device that
has TTL logic chips, then the chips are good only down to 4.75VDC. If
it's a different logic family, it might tolerate lower voltages. And
another point that you have to adrdress is how much curent the adapter
can supply, and how well regulated it is, i.e. does the voltage drop
under heavy load. So maybe you could get some good info from the thread
I started a week or so ago about dropping 6V down to 5V.
