Hi, I am trying to replace a DC adaptor:
Original adaptor from U.S.:
input 110v AC
Cycles????? unknown
The part above is of no meaning. The input side is a non-issue, aside
from considerations about what kind of socket it will be plugged into.
Obviously, an adapter made to work in the USA, with 110-120 volts at the
socket, isn't going to be happy if plugged into a 220 volts outlet, but
that's not particularly important.
output 5.8v DC with 1amp(1000ma)
THAT is the critical information. Regardless of what goes in, what comes
out *MUST* be 5.8 volts of DC, at 1 amp. It doesn't matter if the input
is designed for 110, 220, or 500KVolts - the output side is the critical
factor.
I own a current DC adaptor which is for Japan:
input 100v AC 11VA Cycles 50-60Hz
output 5.8v DC 730ma
Is the difference in amps going to be a big problem?
Perhaps not a *BIG* problem, but it will definitely be a problem. Exact
how much of one is something that I can't predict without a whole lot
more information than what you've offered. (information that you're
probably not going to be able to supply from the other side of an ocean
anyway...)
The think is basically only charging 1.2recharge batteries.
What it's doing with the juice is irrelevant. The only important factors
are the voltage/current/polarity the device wants. Everything else is
distraction that has no bearing on your question. No, that's not a
"chewing out" - just an attempt at education.
Now, having covere those preliminaries...
The 730 mA one you have will probably cook itself in fairly short order.
Your application needs (or at least, your old adapter supplied) 1 amp at
5.8 volts. When looking for a replacement, you *MUST* match or exceed
the amperage rating of the original. Using a supply with a lower output
will almost certainly burn it up, and may do so quite quickly, and with
a large amount of damge to the surrounding area. If you're lucky, it
will "hold you over" until you can get a proper one in place, but don't
count on it lasting any significant amount of time. Find an adapter
wired for your location's (Japan, US, Britain, whatever) AC system that
puts out 5.8 volts of DC at 1 amp or more, with a plug that puts the
proper polarity on the proper terminal of your device. Only then will
you have the "right" adapter.
Anything else is, at best, going to "smoke-test" itself as it tries
valiantly (but in vain) to supply what your device wants. At worst, it
will not only burn itself up, but possibly take along you, your
house/apartment building, maybe your wife and kids and/or neighbors, etc.
