Gofer said:Dear members,
During a visit in the US I purchased a couple of X2X wrist watch 2-way
radios, including the adapter. I enjoyed the product very much. When I
returned to Israel, where I live, I tried to recharge the batteries, and I
used 200-to-110V adapter, to which I plugged the original XA10 adapter.
Unfortunately, due to malfunction of the down-converter, the XA10 adapter
burned out. I want now to buy a transformer, here in Israel, and to use it
directly as the adapter for charging my X2X batteries. I understand that the
adapter output should be rated 9VDC @100mA (2.2W). I need only information
regarding the plug that goes to the wrist-watch. It looks like
stereo-headphones plug- and I need to know the polarity of the voltage,
namely, on the three terminals, which is the positive, the negative, and
what is the third one. Please help me with it. I want to enjoy the 2-way
radio here, just like I did in the US.
Thank you in advance,
Dr.Y. Gofer
Hi...
You're surely going to get far better info than I can
give you (old, long retired) but maybe get you at least
started.
First suggestion is that it's highly unlikely that the
power adapter plug is really "like a stereo headphone
jack" (that would necessitate shorting it at least
momentarily as it was inserted/removed) So, respectfully,
are you sure?
Second would be that you examine the connector with both
your reading glasses and the biggest magnifying glass you
can get ahold of. Standard practice is to mark polarity
on such jacks; but on a wristwatch size device it will be
very tiny.
Third, 100 mils at 9 volts seems an awful lot for any
battery that could be put into a wristwatch. That spec
may be correct, but there must be some current limiting
resistor in series.
Just a start.
