30 amp variac instead of an autoformer?
Hi, I've been looking for a 30 amp autoformer for some time. I wonder if this item would "fill the bill". 30 amp variac $169 Here is the company listing: variable ac transformer

Are variacs capable of increasing low voltage?
Yes, but within a input voltage range.
Variacs are a "buck/boost" transformer, windings are continuous from zero to 130V AC for the output for a given input voltage which I will assume should be about 110 or 115..
One major issue to note is this is NOT LINE ISOLATED IN ANY WAY SHAPE OR FORM..
These are typically used in trouble shooting electric equipment that are having issues at full line voltage but can be used other applications like a huge inefficient light dimmer or a small boost or even buck to line voltage that is a little low or a little high..
A major downside to this device is it is NOT AUTOMATICALLY "regulated" what so ever, so if line voltage increases so doe the output voltage.. If the input voltage decreases so doe the output voltage..
Misuse of this device may result in you accidentally smoking your stuff instead of saving it..
