Power supply and overseas travel

Hi. So I'm currently going to be going overseas and I'm taking my board with me. I have separate 9 volts but they're American. Where I'm going uses European outlets so I decided to buy an adaptor that had step down functionality. Well. I saw it only can convert up to 200 watts. Not even enough for a hairdryer. My 9v have 6.5W on them so I am wondering will this adaptor be enough? That seems like a small amount of wattage to power a few pedals.
 
200W should be enough for I think any pedalboard as long as it's not super uber huge. 200W/9v = 22A, so should be enough for approx 200 pedals each using 100mA...

What I don't know is how your PS is going to handle the different frequency (it's 50Hz and not 60Hz) but it will probably be just fine.

Disclaimer: I have no experience with this, just some general background in electronics.
 
I moved from US to Spain early last year and brought most of my gear with me. I did not get a voltage transformer.

I dumped my voodoo supplies as they are fixed at 110 volts input. Picked up a TRex for my smaller board and Cioks for the larger as they have selectable input voltage 110-220 volt. As a backup, I also brought my 1Spot and Godlyke Powerall, which are suitable for 110-220 volt, only need an adapter plug so that it can be used in the European socket. The adapter plug is much more convenient than a voltage transformer.

For most DC powered gear, including guitar effects, computers, cell phones, etc., voltage transformers are not really necessary as the power adapters are generally capable of supporting input voltage 100-240 volts. 50/60 Hz is generally not an issue. Only thing necessary is the correct plug end.

If you can get away with a 1spot or similar switcmode supply, this would be the best most cost effective external power supply option.

Of course, the easiest solution would be battery power, but that may not be an option for you...

ya. I don't know about the frequency issue either but 200w is a shedload of power. Think about how much heat comes off your pedals vs even a 40w lightbulb.
