Do they work as they say 45 amps

Known as a cheater cord. Will trip a GFCI which is a very common 15/20A plug.

For the cheater cord that has 2 30A male plugs it may also overload the neutral depending upon how the 2 pedestal plugs are wired.

There are other potential safety issues and the use of the cheater cord should be avoided.

For various reasons some CG's do not allow it's usage.
