Just a final thoughton powering, if you haven't thrown away the power unit, the
info you
need as to voltage, current and plarity should be written clearly on the power
unit.

George is right to point to the manual or whatever documentation you have Ian,
and there's a
fair chance you could find details on line, although not necessarily in an
accessable
format.
I'd say though that if you have to work it out for yourself then you will need
a magnifier
or a pair of eyes to assertain:
1. Voltage and current requirements. Voltage should be fairly easy as it must
be at least
the same as the total voltage of the batteries the equipment takes. Current
might be
indicated in writing near the DC socket, otherwise you have to er a bit on the
high side of
an estimated current consumption.
2. Polarity. This is VERY important. You have to find out whether the centre
pin is
positive or negative, and this is where sight could be invaluable.
there are some flexible mains power units about which allow of switching
polarity either on
the power unit, or turning around an adaptor at the end of the lead to match
polarity.
Maplin do such units.
OH yes! There's the size of the socket too. They can vary and there are at
least half a
dozen different physical dimensions for these. Again, many of the universal
power units
come with a bundle of adapters.
So, if you don't regard yourself as very tech savvy, get some help from someone
you trust is
up to scratch on these things.

Ian,
Do you have the make and model of the main piece of kit?
One can often trace what's required by way of power supply
from there.

Hello all,
Over Christmas the mains power unit to one of my pieces of
kit broke
when the earth pin snapped off. Sadly, the broken unit has
been chucked
and I didn't have an opportunity to record its particulars.
Is it
possible to deduce from the battery power required what I
should be
looking for in terms of voltage output etc? And what might
be the other
things I need to ensure are compatible?
With thanks.
Ian
