Yes, Thats is one type but not at that price......
I'm sorry that I cannot remember where I purchased the last one which was under $25.00 and is the KILL O WATT.
The one I use (along with everyone else who gets their hands on it) has the frequency, Amps, Watts along with the voltage output and other doo-dads
One thing for sure...Once your gen is setup your good to go for a long time.
