De Walt DCB101

Unless it is rated for 220-50/110-60, you will need the converter. Besides the 110V US plugs won't plug into the 200V UK outlets.

Can't say for certain, but there are specific 110V and 220V versions of DCB101.
None are labelled 90-220VAC as would be normal for universal voltage equipment.
If you operate 110V equipment on 220V then you will most likely damage it with overvoltage.
If you operate 220V equipment on 110V then you will most likely damage it in over current or have it simply not work.

It is possible that the charger is universal, just not labelled as such.

Have a look on ebay for cheap converters:

if you need 110V US to 220V UK (6.99):

or 220V UK to 110V US (3.00)

Hope helps

More than likely you fried the boards and even if to change them out ,you still run the risk of electrical shock. My advice is to send it back to the company for repair or get a new one. Plugging a 110 unit into a 220 line has happened to me too! I still feel pretty stupid I did it, but stuff like this happens and it is good that you were not injured.

yes!you need to supply also the 220v the control running in 220v,110v only for the motor/s

It is not feasible to convert it internally.

No you cannot as 220v will damage the 110v the Logitech. You need a stepdown transformer to reduce the voltage from 220v to 110v. and then you can safely plug the Logitech into this stepdown transformer.

That thing is fried.If you can do your own electronic repair,there are a few components where the plug comes in that would be cheap to replace.Without a solder gun and voltage meter though I would replace.

your power supply is shorted.. make sure to connect your new power supply to the actual voltage .. 220V is for 220V input PSU.... if you connect your 110V PSU to 220V outlet... it will fry your power supply..
