Adaptors: Exceeding the specified current by 600mA

[Robert]

We use a Panasonic TC1464 cordless phone (9V DC, 200mA), but we have the
problem that its present adaptor doesn't work in countries that use ~220V. I
have another adaptor that has the same output voltage, but a higher current
(800mA).

Could the phone withstand that difference, or is it crucial that the
specified amount of current is respected?

Thank you in advance.

Nothing to 'withstand' with current. That number
specifys the MAXIMUM current that it will supply while
still maintaining the specified voltage, 9V in this case.

or is it crucial that the specified
amount of current is respected?

Nope, just that the specified current
is higher than the device needs.

The short story is that the other one will be fine.

It will *probably* be ok. It's excessive voltage, not current
capability, that might damage your device. I said probably,
because most adapters make a higher voltage than what's written
on them, and a higher-current adapter will need more load to
pull the voltage down to the nominal rating, so the resultant
voltage may be higher than what's expected from the proper adapter.
But if the unit was made to run from a cheap adapter, it'll
probably deal with that just fine. If not, I'm sure Rod will fix
it for you .
