Hey everyone,

I just noticed my WF-188 seems to run pretty hot. I opened it up, cut a hole in the top drilled some air vents and stuck a heatsink on the transformer with some heatsink tape. The heatsink gets really hot. Too hot to keep your finger on it for too long. Is this normal? I'll take some pics when I get the chance.

Mine doesn't get hot. Strange. I'm on 230V, maybe that has some influence?

I have one, and it does get a bit warm... The good thing is it terminates at 4.18v every time, and can charge lifep04's.

Mine dosen't get more than slightly warm either, most odd.
