Switchable between 15v and 18v - the 15v setting works with a lot of Xotic's own pedals including BB, AC, RC and variants.
With my BBMB, besides making it louder and reducing the gain slightly, it's also given it more clarity and tightened up the response - you can really hear the clean under the drive. With a boost pedal in front of it there's noticeably more definition and headroom where previously it would just saturate and compress rather than get noticeably louder, so now it definitely cuts through better.
The effect on my Liquid Sunshine at 18v is even more pronounced - all of the above applies but it really emphasises the tweedy growl, and you really can leave the pedal on and work the dynamics and volume control.
Obviously the voltage doubler will be irrelevant for folks who already have isolated power supplies with switchable outputs, but for those of us on daisychains it's a reasonably affordable way of expanding the options of some OD pedals.

Diago also make a voltage doubler cable that you can use on a daisy chain. Not sure how it compares in price though.
Some pedals will blow up if you feed them much more than 9V.
It's well worth being absolutely sure that your pedal can handle 18V safely.

Most Fulltone drive pedals can run at 18V as well. I think that is normally shown on the pedal though:
It probably should be said though. It's fairly common to see threads like this one where people talk about how great their pedals sound when they run them with 12V or 18V instead of 9V, so anyone in a moment of brain-fartery might assume that any 9VDC powered pedal can be improved by upping the voltage. Next thing you know, you've gone and let the black mojo smoke escape.
I find it really odd that Xotic sell a voltage doubler when not all their pedals can tolerate 18V up them. People who've spent quite a lot of money on their gear are also just one brain fart away from a potentially expensive repair.
