I have recently purchased a 18v liion makita cordless tool kit and would like to have the charger reworked to suit 240 volt
Don't go buying more stuff when you can fix the problem yourself without buying any converter. The modification required to do it is very easy and most people wont have any problem following it.
You can go to this webpage where a detailed walkthrough is given (with pictures):

Some of the post are in norwegian but the walkthrough is in english.
Good luck and happy moding :)
P.S.
For those of you that have "blowed up" a makita charger 110v on a 220v, don't throw it away!
If you are lucky you have only blowed up the fuse and the varistor, which are easy to replace, and if you follow up the walkthrough you might even go all the way a mod the charger to 220v.
I know, I have already manage to "save" a blowed up charger.
Hi all,
I added another HowTo page for modding the DC18RA from 110V to 220V , you can find it here
Have fun and good luck

sorry for your lose
In my mod page it says you might also need to replace the MOSFET
this is not always necessary as some users reported it works w/o replacing it. In addition, did you replace 1 or 2 capacitors ? I was experiencing the same issue and thus wrote 2 capacitors needs to be replaced.
As for the cost, please note that someone is making a profit from you, it should not cost that much ;-(
Hope this helps

Avi - How do I mod a USA bought Makita DC18RC charger to work on 220V overseas?

I purchased a new capacitor, varistor, fuse and a new plug and carefully soldered in the new parts. I connected a battery and with a long extension lead stood back. As soon as i flicked the switch on a tiny puff of smoke and a small pop came from the charger. I have spent hours trying to work out what went wrong. $40 in parts and it destroyed a perfectly new battery. Big disappointment.
'Tis not so easy as it would require a different transformer. Praying that the stock transformer would support both 240/120 might be hoping for a bit much. Aplliances that support both voltages (such as computer power supplies) usually have a switch on them for doing so.
One option might be a voltage converter, theyre relatively cheap... see these:

There are several revisions of this charger, and the physical layout is different. I've seen two sets of instructions for converting from 110 to 220 on the net for the S and T versions.
For the S version: http://www.byggebolig.no/index.php/topic,5572.msg49030.html#msg49030
For the T version: http://www.schneordesign.com/Avi/Makita/makita_mod1.htm
There are different components to change in each version, so you need to use the right instructions. In the T version, the existing Mosfet seems to be able to handle the higher voltage, but Makita uses a 900v Mosfet in its real 220v version. If you want to be cheap, you can use the existing one.
I have a Makita DC18RA Li-Ion 18V Battery Charger
it was from america i bought a converter and plugged it in to 240v not knowing it was 120v it went bang is it knackered??
I don't know how much you destroyed by plugging it in to the wrong voltage. Very likely the varistor, fuse, 2 input capacitors and power switch are burned out, but I'd have to see it. I think the parts cost is more than a new charger would cost, so for your budget and your safety I suggest buying a new one.

Will the same solution required to convert the Makita dc1439 from 110 to 220 volts?

Usually answered in minutes!
the charger is 120 volt im hoping that an easy modification is possible
Will it required the same procedure to convert the Makita dc 1439 from 110v to 220v?
