Hi, thanks for looking at my post.
The Rice cooker in question is from China where they use 220 volt 50
hertz. I want to hook it up to 220 volt 60 hertz.
In case you've never seen a rice cooker, it has a paddle switch that

DC voltage?
Is it possible? Will capacitors and coils be able to multiply/step up
voltages?

    I have the offer of Compter Speakers from a relative in Canada. Given
the different Volatges and Frequencies between the two countries. Is it
possible to get a transformer/adpapter to use them in the UK?
Thanks

Seems to me like about 100 years ago, a car battery gave you plenty of
warning before it died.  Slow cranking etc..
These days, batteries die when one tries to crank and the output drops
to zero (not the 5-7 volts that told you the battery needed
