[Elecraft] Battery Charging

[Don Wilhelm]

Ed,

I am not sure why you chose the Elecraft reflector to ask a non-radio 
related question, but here is my 2 cents worth (and it may be worth no 
more than that since it is a SWAG)

More information needed.  Chargers that have linear power sources may 
have a problem - the transformers are designed for 50 or 60 Hz current, 
so the voltage out may not be as expected.

However, many of the cellphone and camera battery chargers use switching 
circuitry, so my guess is that all may be well.

BUT, don't take my word for it, contact the supplier(s) of your charging 
devices and ask what power line frequencies are acceptable for the 
device in question.  If their technical staff cannot answer the 
question, I suspect they have not tested it under those conditions.

73,
