You could easily to up to 9 volts and 300-350 mA without over charging.

Forgot to add-- make sure the polarity (i.e., is the center positive or
negative) matches and is correct or you'll fry it in a heartbeat....

No. An adapter with more than 200mA is like a bigger glass of water
than one asks for. The battery will only use as much as it wants.

OTOH, I would hesitate to use a higher voltage than recommended.

And polarity is important, essential. I bought as a spare to use for
other things a universal (multi-voltage, multi-plug) power supply
adpater for digital video cameras. Other than cutting and reconnecting
the wires, it has no way to reverse the polarity and for all the
things I have, none of them video cameras, the polarity is backwards.
I haven't been able to find out if digital video cameras actually have
that polarity, or maybe that's why the charger were sold from a shlock
outlet and not at video stores.

You need the same voltage, same voltage type (DC vs. AC) and at least as much
current. Having an adapter that can do more than 200ma is a good thing.

Hi,
If you have removable batteris, charge them with the battery charger RS
sells. Having two sets of batteries will work better.

I hate it when I accidentally hook up an AC charger to a DC battery.

I hate it even worse when I don't check the polarity first. :-p

Douglas Adams did a piece called "war on dongly things" complaining about having
boxes full of AC adapters. He had it worse as he'd buy products overseas and
then have to get a new adapter to handle the AC power and plug used in the UK.

I used to hate RS232 because there were about ten thousand ways to configure it
(DCE/DTE, h/w or s/w handshaking, what kind of h/w handshaking, bit rate,
# bits, # stop bits, parity type, gender of plug, 9 or 25 pin)

AC adapters are worse and they worsened in recent years as the product makers
no longer put their brand name on the AC adapter.

I'm seeing a trend to using USB for power. USB has power limitations but
for many devices that isn't a problem. I now have a pile of USB cables,
each going to a proprietary connector (phone, ipod, etc.) Some devices simply
have a micro-usb socket for their power. I can then plug the other end into
an AC adapter, computer, or cigarette lighter style car plug.

The 200ma ought to be a minimum value. Of course it is possible that the
charging circuit is so cheesey that the impedance of the dongle is
actually what limits the charging current, in which chase the battery
could overheat and leak, or even explode. So try it. If it works, you
will have achieved frugality. If it doesn't, the thing was a piece of
crap, anyhow.

What I really meant to say was that I hate it when I hook up a DC
charger to an AC battery. I was poking a bit of fun at the fact that you
apparently missed that the OP said his device had a rechargeable
battery, so obviously he's after a DC output.

When I store such a device, I made it a point to wrap the power cord around the
device so that it won't get separated from it's ac adapter.

There's no correlation. A device with a DC circuitry (just about everything)
and a device with a DC battery are the same. The device can just as easily
have the rectification in the device instead of the AC adapter and have an
AC input.

Rueful chuckle. At this point, I have a couple cubic feet of 'wall wart'

when I find some new toy at a store that turns out to not include a

it is about 50-50 odds that I have one in stock that will work. I have

Contrary to what others have said the voltage present at the
radio could be critical. It depends on what is in the radio. Some IC's
have voltage maximums that may be reached by some 7.5 volt poorly
regulated adaptors.

A rechargeable battery should not be overcharged. Heat from
overcharging/overvoltage will damage the battery. 7.35 charging
volts is maximum.

A well regulated 6 or 7.5 volt DC adaptor of any current rating
of 200 ma or above will work as far as the radio is concerned, but if
you run into a poorly regulated adaptor the voltage could be 1.414
times higher than what the adaptor is rated.

If you have a few spare adaptors laying around first check that the
marked ratings are at least what the radio calls for. Then measure
the no load voltage to make sure it is under 8 volts for the radio or
under 7.35 for the batteries. Even some 6 volt adaptors can measure
more than 8 volts with no load.

If you're recharging internal battery, the value might be important. Depends
on the design of the radio. The 200 mA limit may limit how fast the
batteries get charged.

If you're using the AC plug to run the radio (play music and news; not
charging internal battery) then higher mA won't hurt anything. mA is power
available, not necessarily power used. For example, you can plug a 1 amp
table lamp into a 20 amp socket, and the lamp uses what it needs.
