I am still trying to figure out whether or not I can use one of my power
adapters on my PowerCD. Someone posted the numbers from his PowerCD adapter
as follows:
Straight from my PowerCD AC Adapter:
Class 2 Power Supply
P4824-1010-DC
Model No. H0037
Input: AC 120V 60Hz 22W
Output: DC 10V , 1.0A (-)--C--(+)
The adapter I'm hoping to use has the right polarity (-___C___+), but the
numbers are a bit different:
Plug in Class 2 Transformer
INPUT: 120V 60Hz 25W
OUTPUT: 12VDC 800mA
Do the input and output numbers have to match exactly? Are some more
important than others? Should I just resign myself to buying batteries
because it's too complicated for me to understand?
Thanks,
Janice
Sorry, Janice, but you have to dredge up a 10V adaptor. I can't understand
the polarity indicators, the way you show them, but I know it's hard to
reproduce this in typing. The polarity is important: the little diagram
tells you how it's set up on that particular adaptor. The (-) symbol will
have a line connecting it to either a dot or the ring surrounding it. These
represent the center pin (or hole on the end of the plug), and the collar
(or metal shaft on the plug, with a plastic insulating collar at the tip,
separating it electrically from the hole). If the center dot is positive on
your ORIGINAL PowerCD wall transformer, then you must use a power adaptor
with a positive center contact (the hole in the center of the plug), and
of course the outside shaft (the metal barrel of the plug) is negative.
And you can't use a 12VDC power adaptor to run a device that requires 10VDC.
You need to find a 10VDC adaptor, rated at 1 Amp or more (1000 mA or more).
I've often found orphaned power adaptors at Value Village and places like
that, usually pretty cheap. Garage sales and secondhand stores are also a
good bet. If you're really stuck, Radio Shack might have one, and they can
help you match the exact power plug diameter and length, neither of which are
standard, and which must both be right for the plug to fit properly. If the
barrel is just a couple of mm too short, the darn thing will keep popping out,
it's a pain.
You're on the right track, and I know you'll find one if you keep hunting.
I'd carry the old PowerCD adaptor in the car with you, so if you find a
likely replacement, you can confirm the plug size and so on. If you find one
that has the right rating (10VDC @ 1 Amp), but the plug isn't right, buy it
anyway: it's easy to cut your old plug off the (presumably dead) old adaptor
and splice it to the new one. You can reverse the polarity at that time, if
you need to. Anyone even casually into electronics can do this, and should
confirm the polarity BEFORE plugging it into your PowerCD.
The good news is that your PowerCD doesn't need a special supply, so you can
use one from anywhere, as long as the output is right. You can't do this with
your PowerBook, for example, as most adaptors can't output anywhere near the
current a PowerBook requires.
Good luck in your search.
