Your kidding right? Did you read the first post? The company, Streamlight, told me that using the 120v plug in a 230v socket with an adaptor is safe and would work. I checked this out with them more then once to make sure. I was told ALL the plugs step down the voltage to 12v and the only difference was the plug shape. No user error but rather very bad and dangerous information relayed from the manufacturer.
Yes I read your post. I don't think however that is all the facts.
And sorry, no 'plug' anywhere in the world steps the voltage down to 12v. If you believe that you shouldn't be using any electric items ever FFS.
What is likely the case is, the charger only uses 12 volts, but has some kind of transformer that will step the mains voltage down to this level. Everything in the EU/UK will state it's operating voltage and I'm pretty sure this is true in the USA too...
Many items retailed outside of the USA will work on 230-110 volts. But many US items are only rated to 120v or so.
As for outdated tech, go check out battery university and read up on the different battery chemistries, or even goggle search this forum for comparisons between the batteries. You'll see that although Nicd is an older tech it's still preferred over Nimh and even li-ion in some regards.
Quite aware of battery chemistries thanks. And the only reason to use NiCd is for poor performance, poor runtimes and battery memory reducing capacity further.
BTW - I'm not trying to have a direct go at you. But are you able to provide a picture of the unit you plugged in? Lets see what it's rated specs are, if it says on it that it doesn't support the voltage you plugged it into, then........
