It’s easy to spot the similarities between this and Stephill’s SHX1000. Both are based around a quality Honda engine and use inverter technology to smooth the output. The main difference we could find is that this one comes with a plug-in 12-volt charge lead for batteries – the Stephill has two screw terminals.
