Might be 300W but how high does the thermostat go? These baby bottle
warmers 
are just that, 'warmers'. Might require some tinkering with the
thermostat or 
whatever to get correct temperature, depending on what you are using of
course.

I have been using ammonium persulphate which requires the 60 to 70
degress 
celcius range. I havent used ferric chloride in a long time.

I ended up buying a bubble tank from the local Tandy store (about
AU$20). 
Connected an old fish tank air pump I had lying around. I found a
container 
that it would stand in so that I could pour hot water around the inner
bubble 
tank. Once it reached correct temp range I start etching and just top up
the 
hot water to keep it correct. I found a 'candy making' thermometer that
I use 
to monitor temperature (about AU$6). All in all a pretty cheap exercise.
