    DEWALT DCB112 charger

    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.

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

                          Lenovo T460 Only Charges on One Charger

                          Laptop Question
                          Hello,
                          I'm working on a Lenovo T460 that has been having trouble charging as of late. Its worked well since I've owned it for a few years. When I went to use it the other day it was dead and wouldn't turn on (was sitting on an Anker 65W GaN charger). After some fiddling with the charger I got it to turn on and start charging, but seemed like the charger was not working as it should (took a few plug and unplug cycles to get it to start charging).

                          A day later it was dead again and wouldn't boot/charge no matter what I did. No lights or anything when...

                          The ISL88739 & ISL88739AHRZ are a highly versatile combo battery charger
                          configurable for operating as either a Hybrid Power Boost (HPB)
                          charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or
                          4-cell batteries. Both configurations allow the battery to work with
                          the adapter together to supply the system load when it exceeds
                          the adapter capability, referred to as system Turbo mode. HPB
                          charger configuration reverse-boosts battery energy to the system
                          bus to help the adapter provide the system power in Turbo mode.

                          Dell Inspiron 7567 LA-D993P odd charger issue
                          by Johndill
                          Hi, I have a Dell Inspiron 7567 LA-D993P that I've just got running.
                          There was corrosion around PU1503 which shorted PC1518 & blew PL1504. (Reference pictures attached)
                          I've replaced PC1518 & PL1504 & the laptop is now running however I now have another issue.

                          Here are the tested scenarios:

                          1. With the laptop running on battery, I plug in the 150W charger & the charger shuts off (no LED, protection mode) but the laptop remains running on battery.

                          2. With the laptop off, plug in charger (LED says on) & the front charging...

                          Hello guys, this autoclave running with 2 thermistors already connected TH1 and TH3(on CN1,CN2 sockets). One for the water temperture and second one for chamber temperature. But there is another emtpy socket for optional third thermistor CN2 wich is for TH2 for object temperature. I wanna add the third thermistor TH2 to CN2 socket. But i can't figure what model/brand/value i need to use. In manual document, there is no info about TH1 and TH3 model number...

                          Highly Integrated Narrow VDC Battery Charger for Notebook Computers

                          The ISL6257HRZ ISL6257HRZ-T is a highly integrated battery charger controller
                          for Li-Ion/Li-Ion polymer batteries. ISL6257 is designed for
                          Narrow VDC applications where the system power source is
                          either the battery pack or the regulated output of the charger.
                          This makes the max voltage to the system equal to the max
                          battery voltage instead of the max adapter voltage. Operating
                          at lower system voltage can improve...
