The thing is made in Germany and originally made for a European market.
They simply didn't update the specs. If the plug is the standard North
American plug it's 120..230 looks very different. You may have seen
conversion travel kits for this very thing (convert your 120 shaver to 230
when you visit Europe)..because the plugs are different. Plug the thing in
and go...
I've been using mine for a month now...got rid of the DIY stuff...I love it.
My plants also are enjoying the c02.

Relax and enjoy the results.

I just got this unit from LFS. The store told me it run at 110V (the
normal voltage in USA). However, the manual says it runs at 230V. Who
should I trust? Anyone tried this in US?
