- Although straightforward, you do this conversion at your own risk. The charger has exposed live circuitry inside when open and its main capacitors may hold a modest charge for a while when the unit has been unplugged.
You make this modification entirely at your own risk. I am not liable for any errors on your side or my side.
The components you will require are:-
A suitable replacement transient suppressor (MOV - Metal Oxide Varistor) like this one:-
www.rapidonline.com/joyin-jvr...
And optionally, but recommended, a 220K 1/2W resistor for across each of the two main electrolytic capacitors for balancing.
Like this pack of 100:-
www.rapidonline.com/truohm-cr...
And optionally a new mains voltage two core flex, with a core CSA of at least 0.75mm.
The two most important things in the modification are that the link MUST be cut and the transient suppressor MUST be replaced. Powering the unit up with either of those steps omitted will result in possible damage to the unit.
As always, just take your time with modifications like these, and make sure you are comfortable with what is required before proceeding.
Bonus technical notes... The charger will initially charge the battery at high current and then switch to a lower current to top the cells up to their fully charged state. It then completely disconnects the battery (relay clicks out) and goes into a standby mode dimming the green LED up and down.
I measured the voltage across the two series electrolytic capacitors (fitted with my extra resistors) and the voltage was shared almost equally with just a two volt difference.
The six screws on the PCB do not hold it in. They are for the two heatsink plates and plastic contact support.
The screws that hold the case together are T20 (E4) security bits.
Once converted to 230V operation the unit should not be used on 120V unless the link is replaced, as it would result in unstable operation of the switchmode supply.
The existing fuse is an acceptable value, even if it isn't the recommended ceramic high breaking capacity type.

One of the best no-bullshit clear explanations of a typical mains input circuitry I've ever seen. Thank you sir!
Nice video. I just wish you'd shown us when you modded the charger, not just the end result. For some reason I enjoy looking when others solder.
Another outstanding vid, Clive, you're the man! Your analysis and interesting patter is reminiscent of a few top notch instructors I can still remember as a jeep radar tech while attending basic electronics school at Kessler AFB in 1957. Yep, they actually taught a full years circuit fundamentals back in the day before one ever got into the guts of the "set" he would ultimately learn. It's been a real treat to get an occasional refresher brush up from a genuine pro, these 6 quick decades later....
I went through electronic principles at Keesler about 5 years ago. I think it was 7 weeks at Dolan Hall... barely enough time for the beginners to learn what a capacitor was. The instructors did a good job with the time they were given. There are pictures on the wall there from classes in the 50s!
I literally just bought a Ryobi drill with this One+ battery system. Glad to know BigClive approves!
the MOVs are usually rated with RMS voltage on the package it self. so the MOV should work fine in the UK. Excellent video as usual!
Thanks, Clive! This video is super helpful for me. I moved to Europe a little while back and have been meaning to bring over my Ryobi power tools but stalled on it because I thought I'd have to either bite the bullet and buy those expensive chargers or run them through a step down transformer. Never would have thought it'd be this easy to convert the ones I have (slightly different type but I'll try to figure them out per analogiam).
So yeah, much appreciated content.
A couple of months ago I decided to learn something about electronics. I must be making progress, I almost completely understood this.
I followed your (very clear) recommendations and now have a fully working 'UK' charger.Love the videos and the accent (Edinburgh?). Keep 'em coming Clive.
I watch all you videos, and because of that i was not afraid to buy a bunch of Ryobi tools last week when i was in the US that included this Quick Charger. I have now modified the charger according to you instructions, and it works perfectly! :-)
Thanks Clive for a super TH-cam Channel - keep up the good work!
Greetings from Denmark.
Looks like that pre-exploded power bar came on handy after all ;)
glad i wasnt the only 1 who knew where it was from :)
I'm not going to lie, I looked for it a bit at the end when he started up the charger.. Then it hit me like a ton of bricks. LOL! It's been a while since I watched that one, but man... You might be even sicker than me for noticing that! x3
yeah, I'm kind of a big fan of clive
I wasn't happy with the supplied Ryobi charger. In my mind, the battery should go on the charger, not the charger on the battery!
Whilst in the states I saw this charger and thought I should research if it would work in the UK. Almost instantly I found the link to this video.
I ordered the parts and received a 14N431K instead of the suggested 14D471K. Fitted it, cut the link, added the 4 resistors and the charger worked first time.
Thanks for making this video.
I just bought one of these chargers from someone for spares or repairs and I knew instantly what had happened as I know you cant get these chargers in the uk so I got it for a good price opened it up and instantly noticed the fuse was disintegrated and the move was blown to bits straight away I knew someone had plugged this charger into 240v so I replaced all the components and did the 240v conversion on it and I've got it working thanks clive
One of the best video i have ever seen on youtube!
Thank you so much for your explanations!
Just pulled out the only traced cct I could find of a PSU using this 120/240V switching (a 200W PC PSU traced in '93) and it had 120k ½W balancing resistors across 470u caps, so your 220k across 220u looks spot on.
This charger th-cam.com/users/postUgkxknS1MWclRHOKWekYXnBJz8Ex0rEPnrGF 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.
Thank you, this is a very important video, so that companies don't keep thinking they can sell their stuff cheap in one part of the world and rip off customers in another part.
Ryobi sells cheap stuff and crappy design stuff at a high price in all parts of the World.
@@BTW... LMAO
Another excellent video Clive :) Please keep them coming.
Thank you very much bigclive! This type of hack/conversion is great, and so satisfying to do.
I was just thinking about it the other day, how the standard one+ dual chemistry charger takes a couple of hours to charge even the small (but good capacity actually) 2.5Ah battery. That one is charging at up to 1.8A according to specs. In Europe we get the RC18150 5A charger, which looks similar to the 3A P117. I have to do some price checking now! :)
If I can salvage and reuse the parts needed for the conversion, I will save the equivalent of £10-15 on a P117 off eBay, compared to buying the RC18150 here in Norway.
Thanks.. today I converted my P117 charger to 230V and so far it's working fine (no magic smoke nor fireworks). My only problem was to find the right screwdriver to remove those 4 fu.. tamper proof screws (I think they're called torx internal tamper proof screws).. It take a lot but at the end I found a bit that came on a set I bought several years ago and I've never used... until today.
I would have been tempted to try removing the varistor and also tempted to see if the series cap's balanced themselves, or used a zener diode on the output, but I don't know, so bow to your greater knowledge Sir Clive....
Nice work as usual its very educational watching your channel some time i think i am beginning to learn a little bit of how electronics work. Just enough to be dangerous
Congratulations on the successful conversion. I did kinda want a kablooie!, though.
Thanks Clive job done as you showed us I used the 220k resisters works well Jeff.
Nice Video Clive!
Good explanation, great video. Thanks for all you do.
Very nice...
Like this video..... Very much!
It would be very interesting to see the other way around too, ie. LED stuff from 240 to 120.
THANK YOU. I was very surprised when I bought this think in the US that it wasn't universal voltage.
The regulations are requiring the stuff to 'be green' and waste less power. So they put the jumper or for the PC power supplies they put a 120 / 240 switch.
Clive is there a way to convert a battery operated drill or tool into a wired form? As you know the batteries die and it's often cheaper or more practical to just buy another drill.
Is there anyway to utilize these drills that are mechanically fine but have no battery packs? or do you have another suggestion?
Possibly an idea for a video?
It reminds me of a Roomba power supply that I converted to 230V - It was even simplier: Replace MOV and one capacitor and you are good to go, all other circuits are common with EU version :)
You wouldn't need the R's if it's only intended for 120v use. .. useful video thanks!
One thing to also look at is the voltage rating of the fuse - in the USA fuses may have been used that are only rated for use with 125VAC.
The voltage rating is a separate matter from the max current rating, in case you think I am confused …
I was just looking to change the brake light bulb...
Then I found this. Awesome and scary.
Thank you, it worked for my P117. I also tried P118 - didn't work.
I once plugged a 120VAC power strip with surge protection into a 240VAC outlet. BANG! instant removal of the MOVs! It rattled a bit from the pieces inside. ☹️
excellent, now i got to figure out the ridgid charger...moving to Philippines need 220v my charger is 110v
Should one replace the fuse with one of half the current as well? With the change of current would the in rush device also need to be changed to be complete? Why not replace the two caps with a single one or two in parallel?
I've been waiting for the Usb C PD adapter for my Ryobi batteries for several years in Canada. I have the normal inverter but going from DC to DC is much preferred. I hope they release this soon so I can charge and use my Ryobi batteries with USB C chargers and devices.
You should have included the de-soldering and soldering part. We all love watching your soldering.
Such a great explanation. So great that I'm somehow understanding everything. Your fabulous accent is just a bonus, where is that from? =)
+Ace Futura Scottish accent.
I thought so! But my friend who lived in newcastle was like "no, he's english" (we're Icelanders, and not versed in your island's many many accents)
Big Clive and his teacher voice love watching these videos just needs a tweed jacket and elbow patches
No no no, Clive's too trashy for that.
He'd come in to lectures with sweatpants on and an orange jacket.
I'd come to those lectures even if they were at 8am. But knowing Clive they'd be anytime between 10pm and 4am.
It's OK. There'd be a bar and hot snacks.
That's more @ralphydotcom 's gimmick.
@@bigclivedotcom can I do this with the P118 the black charger.
Thank you Big Clive!
great explanation. but not sure I understand, the second transformer need not to be replaced since the original design using only half of the sin wave? does it mean that after the conversion the output will be twice?
My guess (based on the odd placement) is that they will use a single 400V rated capacitor instead of the two 200V ones so they do not need those balancing resistors.
Correct. Optimally when used in the voltage doubler configuration there's no need for resistors and when used at EU mains one single capacitor would be used.
18:10 those two contacts are bridged together by the battery, and that's how the charger determines when a battery is present. I bridged them with a screwdriver for no good reason and the red LED started flashing as it does when it's analyzing a battery
Hi Clive, Do you know if you can do the same thing with the P118 PSU? As you say tools from the states are much cheaper but the kit of tools I'm looking at comes with the older P118 PSU. Many thanks.
Thank you for this.. I think you should have done this a month ago.. I could have used in converting the Milwaukee 110V charger. I did change the caps, and the clamp, but still might have burned it :(. With your suggestion I need to check the link from AC to the middle of the two series caps.
wow, so simple to convert us/chinese/taiwan voltage power supplies to UK/Aus rating :D. i'll keep this in mind if i find something i want to bring home and its a switch mode power supply.
It's not always as simple as this. They clearly designed this PCB to accommodate both markets.
My mods are not to the supply but to the tool/battery interface. Using a 3D printer to make adaptors for my old cordless tools. Using black and decker batteries in a dewalt for instance
Hey Clive you can buy these 30 mins chargers here from sweden aswell also Roybi im guessing its cheaper in shipping
Have you tried RS components?
They do free mainland shipping for any sized order. No idea what their IOM surcharge is (if any), but it has to be less than Rapid.
Thank you bigclive for sharing this video. What about the fuse dose it need changing ?
The fuse should be fine. It would only blow in the event of catastrophic electronic failure anyway.
YEAH... SUCCESS !! Very POSH Sir Clive :)
Thank you, I find it straight forward and I think even I could do it. There is but… the video was made about 4 years ago and now this charger has been replaced by Ryobi P118. Can you please describe main defences between two and see if that conversion would also work on P118.
Thank you ;)
I found out the wire with markings on it is the neg or blue for uk plug.
you should make a video about how to safely discharge large capacitors
Just put high value resistor to slowly discharge capacitor with small current
Clive, you'd be able to add a switch where that link was right? Then you'd be able to change between the two supply voltages right?
You could probably use a 2 pole 2 throw switch to also select between the two voltage dependent resistors too.
The same MOV would suit both. the risk of the voltage switch is that if it gets used frequently, then one day the unit will be powered with 240 while set to 120 and suffer damage.
Good explanation. I had a 110V Ryobi charger connected it via a Voltage converter. The converted was capable of converting in both direction. Unfortunately I missed to select the output voltage to 110V and killed the charger with a 240V input. What component might have been damaged?
thanks for this useful video
Another great and very interesting video! Thanks, Clive! :)
It may have been a bit cleaner to replace the two capacitors in series, with a single 100 uf 450 V Capacitor, and leave out the balancing resistors. Nice explanation.
+John Coops a) a cap like that is a lot more expensive than a couple resistors b) the whole point of the link is to make it a nearly-dual voltage standard supply. No need to make it difficult to convert back.
These capacitors can get somewhat expensive. And it may be difficult to get a matching quality one like those in a top-notch power supply.
I would personally leave the resistors out, or use 1M resistors like the computer PSUs have. The capacitors don't really need balancing because they have extremely high internal resistance and that resistance tends to go lower with voltage creating negative feedback. I've been running several for over a year without an issue. No balancing needed. They only put the resistors in there to reduce the risk of shock.
In some cases, such as older and/or cheapo computer PSUs which employ a half-bridge topology, that's not really an option, since the center tap of the transformer goes to the mid-point of the high-voltage DC rail.
Not in this case here, since it's a "lowly" flyback, but "just sayin' "... :)
That being said though, i shudder at the sight of CapXon capacitors >_< Preeeetty sure the 200v ones are KM's.
Jeez, if you don't even like capxons, you've got real high standards.
Jasper Janssen You're almost making it sound like that's a bad thing :P
Thing is, CapXons **WILL** fail, same as Fuhjyyu, and countless other chinese (off-)brands.
Let me put it this way - i trust the USED japanese caps i've reclaimed from various gear i've torn down & gutted for parts, than any of these crap brands, even if new.
And in the next video - an autopsy of a slightly melted Ryobi battery charger hehe
Slow clap. He knows what he's doing. You don't because you weren't even able to recognize his knowledge.
The use of kapton tape, the MOV that's really gilding the lily in terms of reliability... Something else might fail, but not the components he has replaced!
zwz • zdenek You missed the joke of it - I have watched enough of Clive's work to know he is very skilled with electronics, but that does not preclude some friendly ribbing!
Paul Roberts
Ok.
Weird request. The UK has a super fast charger not available in the US. Any chance of showing how to make that one work on the US grid?
Intelligent. Very nice.
Clive, you did *not* lose the little green MOV. It stole the show from 14:23 right to the end of the video!
hello i have an hilt c4/36 CPC is in 110v and i put a 220v electric plug, but green light is blinking like temperature problème, and battery don't charge there is something more to do?
BR
i think the circuitry for operating without the relay engaged is for a pre charge function, for when the battery is under voltage, but i might be wrong
Hi Clive what fuse should I use a 3amp or 13 for 3 pin plug thanks again for your time learning all the time. Jeff
+Jeffery x 3A is recommended.
Thanks Jeff.
really enjoyed this one, but wished you had zoomed in on some of the smaller details.
Hi, we are moving back to the UK with a bunch of Ridgid lithium battery tools. The charger states that it is 110V ~ 60Hz. I know that I can get a step-down transformer to supply the charger, but do j need to worry about the differing frequencies? Ryobi and Ridgid are pretty interchangeable here, and you don't mention the frequency compensation in this video so I was hoping that it was a non-issue. Any help would be appreciated.
There is another garden tool company, Greenworks, that make products much cheaper for Brits to ship from USA and have the same unavailability of 240 volt AC input for chargers of 40 volt output and 80 volt output. Be great to see mods of those, particularly the 80 volt, if they come your way.
Thank you, this was very interesting. Wondering what do you call that terminal used to plug in the stripped wires with the red hinged cover at 18:42? I would love to purchase one of those thingamajiggers for my projects. Thanks again.
It's a Cliff Quicktest.
@@bigclivedotcom Thanks again. :)
Hello, i was wondering if i you can help me converting a Ridgid charger to accept 220vac model(R86092), currently the charger accepts only 120vac, thanks
Are the class Y capacitors rated for the higher voltage?
hey i accidently left my love 120volt charger as show in this video plugged in and applied 240volt to it. now it doesnt work. what do you thinkni blew in it. fuse looks good
What about the switching MOSFET voltage rating???
What about a UK plug charger in america?? I got the bosch mini chainsaw and need to convert it to US.. the bottom of the charger only says 220-240 50/60.. but the caps and everything inside is 250v :/
Huh, I was also kinda confused about the absence of resistors to discharge the capacitors separately. They are only discharged in series, but discharging them in series and possibly reverse charging one of them is generally the problem, not charging them in series. So yeah, rather strange. I quite like the way they stepped up the voltage though.
I also like that it's essentially possible to convert it by simply cutting a wire and removing the metal oxide varistor (which isn't really necessary for normal operation). Although I would also feel better at least adding the resistors, just to be safe.
Could I insert a switch between the rectifier and the capacitors instead of cutting the link, to make the charger switchable between 110V and 240V, or would the threshold of the varistor be too high in 110V mode?
They are a lot better than any other tool at this price. And the batteries hold up 10 times longer than Dewalt NiCads.
Instead of the resistors on the capacitors, could you just remove the caps and replace them with one single "uk compliant" capacitor?
Question re capacitor X2 (100nf 275V).
Would that survive the 240V input (~330V peak) or should that also be replaced with a 400V capacitor?
A 275 AC capacitor is rated to handle the peak voltage of the AC supply.
Any hints how to charge such battery with RC charger? I give 5S rated voltage on + and - terminals and after some time I get broken connection error (somehow BMS disconnects battery).
That bit with the link is the exact position of the 110/220 switch in just about every PC power supply that I've torn apart. I have a number of those switches around if anybody wants one.
isn't the diode at the bottom supposed to be conducting effectively shorting the bottom capacitor?
Hi there, How to check the electronic parts of the Ryobi P117, and Discover the problem
Hi Clive I thought I let you know they are £47 all in from USA no better then UK now got one coming got parts ready to fit you said the red wire goes to live in plug the cord looks black in video thanks for your help with this. Jeff
I made this conversation to use my US charger in the UK (240V). I did not add the registers. It turns on but when I put a battery in to charge it the testing indicator (flashing red led) comes on and remains flashing; it never switches to the charging indicator.
The battery is a good, working battery, nearly new and charges normally on my son's UK charger, which switches from testing to charging almost instantly.
I don't know if it is actually charging on my modified charger; I didn't want to leave it flashing 'testing' for long in case it was somehow damaging the battery.
Thanks Clive for a crystal clear explanation. I used this video to convert this charger 3 years ago. I recently bought another one as a backup and to increase charging capability. The new one (still P117) seems to have a slightly different circuitry. I'm no electrical/electronics engineer and so I'm stumped!! Got any tips on converting the new version (Made in Vietnam, previous was in China)? Not sure if it is possible for me to share photos/video.
I've not seen the new one.
Old video but can you use one leg of the 240? And a neutral to make the 120? Like we do in the US.
We just have neutral and 240V. If we went across 2 phases it would be 415V.
What was your setup for the camera sir?
Hi Clive! After removing that link, will the MOV replacement (14d471k) work for 220v? Or should I find a smaller one?
A 471 (470V) MOV should be OK as is.
Great post Clive, I have a question. Having rushed back from the states and plugged it into the 240 outlet of a duel transformer in haste I've blown both capacitors! What is your recommendation - try to source the same two US spec or replace with a UK spec resistor or resistors ?
I would imagine UK spec ? If so can you clarify if one or two and the exact specification please.
Many thanks again
You may have caused more damage than just the capacitors. You could try swapping the capacitors and maybe the transient suppressor too if its been damaged.
@@bigclivedotcom Thanks Clive appreciate the response. Im about to transfer the new Capicators today as described in the video. Will let you know how it goes
No Joy Clive - Will try the transient suppressor once Ive found out what Im looking for ...
How about the P118 Ryobi Black charger.
How did you exactly cut the link?
How about a video to convert my 120v ryobi 40v charger to operate under 12v dc from my solar system
Clive, are you aware that RS is now free shipping. I am not sure if this covers IoM but is worth a look. I have switched to using RS more for oddball items because of this.
Hmm I would also recomend that the Inrush Current suppressor is changed as well as it draws the same power rating in watts but as voltage is doubled the amps is halved so inrush supp resistance needs increasing. Also fuse rating will need to change as half current. Maybe Im wrong but food for thought...George
Now all Clive needs to do is show us a left hand drive to right hand drive car conversion and we will have the US market all set,,.. 😜
Hi , thanks for the video , I'm not from UK and I would like to follow that video and convert my charger from 120V to 230V . Can you provide ebay link for the parts required . I cannot order it from this British site.
I don’t understand which link did u cut. I see the link still there.
Has anyone done the reverse? I have a Ryobi BCL14183H 220V charger and I'm wondering how difficult it would be to convert it to a 110V charger?
