Hi all ;
I am planning a vacation to Ireland and shopping for a travel adaptor.
All the ones that I find online state that they do not convert the
voltage - which is OK for the laptop converter - which will accept
240 volts 50 - 60 hertz ; and OK for USB charging ;
- but what about other 120 volt devices like my camera battery
charger - that are 120 volt input ?
Are there better adaptors available that reduce the voltage ?
or some other option ?

First be sure that your other chargers are not 120/240. Usually if
they are big clunky things they have a transformer in them and they
are single voltage. The smaller, lighter ones are "wide mouth".
I would also look to see how many of these things charge with 5v or
12v. There are plenty of wide mouth supplies that output 5 or 12v.
When we went to New Zealand I went through all of my chargers and all
of the equipment I was taking and found I could run everything from
230v with something I had.
I left all of the 120 only chargers at home. Then I got the right plug
adapter and I took a couple cube taps so I had plenty of 5-15
receptacles available.
