Hi! I have a camcorder that I need an AC adapter for, and I found a
universal AC adapter at BestBuy that should do the trick accept for one
thing: the voltage needed by the camera is 7.9v at 1.4amps. The
universal adapter has two voltage settings that are close, but not
exact. The adapter will supply enough current, so I know I'm fine
there. One's 6.5v and the next one is 8.4v. So..if it seems to run ok
at 8.4 volts am I ok?? I mean, do I run the risk of frying my
Camcorder b/c I'm pumping too much voltage through it? Half a volt
doesn't seem like a lot, but I thought I'd ask to be safe. The
instructions for the adapter say "[this device] is fully regulated
using high efficiency switching technology and features overload and
short circuit protection."

You should be fine .. that voltage is probably sent through some kind
of regulator inside the camcorder anyway. (probably 6vdc circuitry
inside).

If you are really paranoid, just get yourself a 3amp silicon switching
diode (1N4001), and break the + line, and feed through the diode.
When you draw current through the diode, you will get a .5 to .6
voltage drop, putting you right around the 7.9vdc you were looking
for.
