I have the SS331B version. It uses a FSCQ1565RT SMPS controller/driver. This chip is specified to produce 170W for voltages between 85 and 265 VAC. So there's a chance it might work. But there is no gaurantee that the H version is using the same chip, nor that Mr Pros Kit has designed the rest of the circuit for operation at 110V. It's a bit of a gamble!
I've attached the schematic that I reverse engineered from my B version. Beware that I might have made errors in transcription.
