How to convert your 110v(120v) DCB115 DeWalt Charger to 220v(240v) 

This charger ru-vid.comUgkxknS1MWclRHOKWekYXnBJz8Ex0rEPnrGF works great with the DCB205 and DCB203, I've charged both a few times without issue. After I'd searched for a while this was the best value charger I found and it's new, boxed up well, and it's built as well as any charger I've had.

well mate you are lucky the capacitor didn't blow up on you, never connect 120 Volts equipment to 220 , especially switch mode power supplies they will cause damage. the capacitor was rated for 200V max and you used on a 230 VAC above the cap range , not safe there is not polarity for the resistors , what you basically did was a voltage divider Vout= Vs X R2 / (R1+R2) , you replaced 2 jumpers with 0.33 ohms resistor per the above formula 220X0.33 = 72.6 , 0.33+0.33= 0.66 Ohms 72.6 / 0.66=110 Volts

BS D Dear Rian Thank you so much for sharing with us your video, I wish you could show us much slower how to complete the work you did , and also maybe a close up for the parts you used. Thank you in advance

Para cuando el 1104, el cargador Dcb 1104 , podrias hacer un video con el dcb1104😢

The grey line marks the negative side of the cap, resistors are not voltage polarity sensitive components. It doesn't matter which load of the resistor goes to the positive or negative due to them literally being a resistive wire.

The fuse on my DCB115 also blew, does anyone know where I can find this 4A250V radial fuse?

Totally wrong about the capacitor and "resistors polarity". And I am against using a gas powered soldering iron for soldering PCBs.

I UNDESTAND THAT IT AN OLD CHARGER,,,,,,,BUT MINE HAS BLOWN THE OSCILATOR CHIP OM THE HIGH SIDE.......CAN YOU GIVE THE NUMBRE? MINE SAYS R695....... BUT ONE DIAGRAM I HVE FOUND SAY THAT ITS THE HP3D6.......CAN YOU GIVE ME TYHE NUMBERS ON YOURS

What do I need to chage to reverse from 220 to 110v ?

He estudiado mucho estos cargadores, tengo de 110 v y 220v originales, de una y dos baterias, carga normal y rapida lo de las resistencias de loza esta bien, mi cargador rapido de 110v es igual al de 220v, lo unico que cambia es el condensador y es verdad que uno lleva unos puentes (110v) y el otro lleva resistencias de loza (las que tiene el mio son de 0.82 ohms 5 watts muchos preguntan que sucede con la frecuencia... bueno para el trabajo que hace un cargador no es problema 50 o 60 hertz, el problema se ocasiona en maquinas que poseen motores, pero este no es el caso Los cargadores dewalt vienen casi listos para usarlos con ambos voltajes, no los fabrican con un interruptor de cambio porque sube los costos de produccion en Tailandia (pais donde los fabrican en su mayoria) Incluso en el caso de Milwaukee es mas facil el cambio (solo se cambia un varistor y se corta una pista en una etapa )

Resistors don't have polarity so it doesn't matter which way you attach it.

Send the part number for resistance

can you make any dewalt charger to work like DCB119 vehicle charger?

Works perfectly... Excellent instructions. Only difficult part was removing the T15 torx screws from case. They have security pin so normal torx T15 wrench will not work easily... You tube using flat head screw driver to remove torx screws with security pin... Simple thereafter. I used the legs snipped off the resistors after mounting on PCB to extend existing legs on capacitor as it's too short and thick with its standard snap-in connectors.

what the resistors are for ?

I did just like you, the charger worked for about an hour fully charged and then turned off. After testing I found out about R3 (270Ω) Found near the replaced capacitor was destroyed. What did I do wrong and why did it happen?

hi you can tell me how to change Ridgid charger R840095 to 220v or anyone have AEG same charger which is 220v ?

Subbed and liked! I have some dewalt cordless battery chargers that are 110 volt. Carrying the large stepdown/step up transformer was a pain. Excellent video! Cheers from Australia 🙂👍👍👍

if I don't add the resistors but I change the capacitor will work perfectly , so my question is why I have to add 2 capacitor of 5 watt 0.33 ohms ?

Why putting resistors in parallel with shortcuts? It basically does nothing, it makes no sense Also, what about the 250v T4AL fuse at the very beginning? Isn't that gonna burn / ruin on 311v peaks?

Is there any problem if I use 5w 0.27 ohm

thanks your video and try it last week but no light on so i don't know what happen and didn't changed another components. (exchange 1 cap and two resistor only according your information)

Thank you very much for the video I want to convert another Devolt charger, its model DCB 107. Do you have a video?

Does this modification allow charger to work on 50Hz instead of 60Hz ?

Dear Riaan I am really excited to find your channel. I have a question about this article . I plugged my 110v dewalt charger to 220v ,and suddenly remembered it is 110 .After that , when I unplugged it and plugged to a 110v source ,it worked fine , but the charging process took just 30 minutes for a 2ah battery .Do you think its normal or it is damaged ? Best regards

What is max drain-source voltage of mosfet? You changed switching voltage 156V DC to 320V DC. Mosfet drain-source voltage must be min 600V. Otherwise will burn/short circuit.

Hello, nice video! if I have this DCB112 charger and I would like to use it on 220V outlet, can I use a 220v to 110v transformer? the transformers are 300watt, 400watt, 500watt max. Is its going to work with a transformer like this?

hi everyone! i'm about to do the same. its been awhile since you guys converted your units... how does it fare now? still good? thanks!

Hi Riaan can you help me? How i convert dewalt dcb095 to 22v, thanks.

I think you have mistaken to say that the white line in capacitor is positive. It is not positive. Also the 5watts resistor. There are no polarity on that resistor. Just to correct the misleading information.

Im trying to do this the other way around

What’s the difference between DCB112 and DCB115?? Will this procedure work on DCB112 as well? Thanks guys

Capacitor 450v 100u It is good?

Although it charging,this is imperfect solution,since it's overheating and ends on Hot/Cold delay (both lamps blinking)

Hi, this is awesome! I am need to convert my DCB1106 - It pumps 6A. Can I make use of the same goods?

, thank you for this video thank you so much my friend

Thank you Riaan. From the Philippines.

It works

Can you make a same video for Black&Decker inflator BDINF20C? I want to convert it from 110V to 220v but dont know how.

HOW TO CONVERT Noco Genius G7200 110v TO 220V? Tank you very much!

I put 0.39 resistors, also works great. Like!

Thanks for this video Very helpful I also just received DCB205 from the US and did not think about the voltage Will have to ask someone to do it for me as I don’t trust myself to do it alone

Hello Riaan! my dewalt 110v charger was accidentally plugged in to a 220v, what are the possible compents that have broken. as of the moment when you plug it in 110v the red light is just flickering.

hi Riaan I have DC9310 the capacitor is 560uf 200v what do you recommend as a replacement ? 220uf 450v / 150uf 400v / 100uf 450v or something else? thanks

Hi Riaan, I watched in some videos which do same job by adding a varistor at the ac input, and a thermistor and changing the capacitor. What do you think ? Which way is better ?

Becareful! This guy clearly has no idea what he is doing. Resistor have polarity? The white minus lines on the capacitor indicate the positive side? Really??

How the output voltage remains the same when we increase the input voltage. Why does the output voltage not increase as the input voltage increases? E.g. for 110V the output is 20V and for 220V the output should be 40V.

Hello I bought greenworks drill and impact with fast charger 110v How i replace to 220v?what i need to buy?can u send links? Thanks

Hey! Are you Afrikaans!?

thank you. it's work!

please make a clear schematic, I still don't understand

Thank you Riaan Keyser ! As an Electrical engineering student (2nd year) I would love to understand more about the way the resistors you installed helps in this circuit. And why is the new capacitor needed ? Thank you

Hi Riaan . What about the jumper ,do you remove it for instal the resistor? Thank you

Very useful video. Thank you very much for sharing.

Thank you so very much, a question regarding the resistors, my charger is DCB112 so it has a different circuitry so could you help with the jumper location please?

So today I did the convertion on my charger and it works,but the light for fully charged is not working. the battery get's charged but when fully the light is blinking one short and one abit longer blinking. but it's get the job done I suppose.

Do I need to change the Diode bridge as well?

The capacitor is used to filter out ripple voltage from a bridge rectifier (converts the incoming AC voltage to DC voltage), if anyone is curious. The reason why the capacitor needs to be rated for 400 volts or greater is because the DC voltage is way too high. Consider that your country uses AC voltage ranging from 220vac to 250vac. Remember, that is the RMS voltage. Multiply the RMS voltage by the square root of 2 (1.414). Once the AC voltage is rectified, your DC voltage will be 311-353.5 volts. Now, put that voltage through an electrolytic capacitor rated for 200 volts and...pop!

The white lines indicate the negative pin. Thats why there are also minuses on it ;)

Hi Riaan. I don't understand why you don't change the capacitor of 220uF/200V for one of 220uF/400V. And you say than the ideal is 150uF. Could you explain it please? Thanks

Hi Riaan, just subscribed, How can I convert a battery charger of Input 110 volts out put 24 volts 25Amps to 220-240 Volts Input, 24Volts output, 15Amps, charger is Copper coil type.

Thank you it's Wooork!!!!

thank you, i did it and it works very nice i just used 450 instead of 400

I recently purchase "Dewalt DCB115 230v @ 50 hertz" battery charger in UAE by mistake. And I am using this in Philippines which is using 60 hertz not 50 hertz. My question is, is it ok to use it in Philippines?

Can i useing this component ceramic resistor value 5v/0.22ohm or 0.33ohm what is the best way tell me

I did what you did on this video and my charger seems to heat up a little bit more than usual. Is this normal or did I do something wrong?

Hello, does it still work? because soon I will make the modification

Can I replace 5w 0.47 ohms?

Hello Friend. How many AH does the battery charge, how long does it take?

Hi Riaan. Waar het jy die cap en die resistors gekoop? Ek is in Noordwes en kry nie plekke wat daai spesifieke komponente aanhou nie. Sal enige raad waardeer.

Resistors are not polar. You can put either lead in either hole.

THat was great thanks!

Thank you for the tutorial, very good

Good afternoon Riaan, I ask you a question given your experience, I connected one of these chargers without noticing that it was 110v to a 220v network, it obviously flew, but when disassembling it I only see a fuse at the entrance that measures it has continuity, and the capacitor that burst. The question is, will I be in time to make the change that is recommended in the video?

Where did you get the components? I need to do exactly the same surgery on 2 Dewalt chargers.

thanks for the video, im unable to find the 0.33ohm resister, can i use 0.22ohm ones?

I need to do the opposite, I have a European charger 220v and I need to use it in America 110v, can you please explain me how can I do this? Thanks

resistors doesnt have a polarity

Better you sold this in US and could’ve bought a 220v charger in local store

Kogan has a sweet little step-down transformer with twin 110v outlets for $20 AUD.

your charger DCB115 have humming sound (noise)?

Hello, could you please check what is the symbol of MOSFET used in DCB115 (black element screwed to upper radiator)? I am trying to convert DCB118 from 110V to 220V, but I heard, MOSFET used originally in DCB118 110V does not work for 220V - it burns. So I tried to verify how it was done in DCB115. Thanks in advance

Is there a problem in merely using a step down voltage converter instead of converting the components? I've been running my old style Dewalt 18v XRP charger on a converter for about 10 years but my 2nd set of batteries just died. Curious whether it is due to the use of a step down converter or that's the lifetime of these batteries. Also, the charger is 110v 60 Hz and we have 50 Hz here. Thanks!

GRAZIE !!!! PER LA TUA SCUOLA ++++

Hi Riaan, I have a Bosch WC18C charger I got in the States and have the same problem (in SA) - do you have any info on converting this?

Hy sir y have the same charger 220 its not charge not led its ded YOU now its have a fuse And were it iz

Anybody knows if it can be done on the 4 ports charger dcb 104 ?It was launched in US two years ago and still cannot be found in Europe. There are many for sale on Ebay,but they're for 110V. Thanks.

god job !

Riaan does your charger still work and batteries are still ok? Looking in doing the exact same thing.

Does the quality of the capacitor important. There are capacitors from $1 to > $15

could you please convert dcb101 to 220V?

I want to do the opposite with a different brand charger. But I am not sure what needs to be swapped if only the capacitor or anything else.

Hey Riaan, 3 Questions: 1) Why didn't you put a 400v220uf? will it be better than 100uf? 2) Should I put a fan? 3) Did you cut and replaced the cable to Europe plug cable?

what will happen if charger 220v plug to 110v?

Hi, can I use larger values for resistor?

Instant sub

What is the voltage that should be in the port after the change?

Hello, Since the video is now some month old, is it still working and did you checked the voltage on the battery connector pins ? The led can come out and blink .. but the voltage can be wrong. Cause i can't see how a capacitor swap can solve that 110V difference.

Can I use 5w 0.22 or 0.5 instead of the 0.33?
