I found this tubular heater, i think it would work great in the tent cause my temps have been anywhere from 45-60 degrees F....!
the power plug has a funny looking one on it, like most of the tubular heaters ive found actually.
is there a way to convert these?... its a 3 pin it looks weird like ( '_' ) instead of ( '.' )
maybe reccommend some tubular heaters that have US sockets?!! thanks.fast replies accepted!

bump, i need answers is anybody out there..

I use a small tiny room heater. It stands maybe 8 inches at most with a 4 inch fan and can get a bedroom HOT. Has different settings on it and heat levels. Really quiet too. Plus since its moving air it has that as a slight benefit

try omega.com, they have 120 - 240 volt i believe...peace

bullyrocka, whats the Watts on it tho? & amps if possible? im on a budget with the electric

its very minimal, off the top of my head im unsure. headed to work. trust me, my wife dont like the electric bills either.
