DEWALT DCB112 charger

[buchman]

Hi,
I have this charger and I want to convert it from 110 to 220 AC.
I can't find the conversion instructions over the internet for this model.
I know that I need to replace the capacitor, add a varistor and a thermistor.
I know how to replace the capacitor and where to add the varistor but I don't know where to add the thermistor.
Someone can help me with this please?
Photos attached.
Thanks in advance.

just put a 400v cap in it and try it.
these things are so cheap i'm surprised there isnt more info online.

btw, that american power cord isnt legal or safe in europe - you need a double-insulated cable.

Thank you for your reply. I am going to replace the power chord of course but I want to add the thermistor to eliminate sparks when I plug it to the wall socket.

i dont think 100uf is going to cause much inrush

What is the P/N as printed on top of the SMPS IC1? It may need more than just capacitor Voltage rating change.
