Clearly since making this video, I have been notified that I left a few things out.
1. The drill that I was using is a 14v drill from Ryobi. It was picked up from a garage sale for almost nothing, but didn't come with a battery charger. It wasn't worth going out and buying one.
2. The power supply is an old laptop charger. It is 15v and 8 amps.
3. YES I should have used heat shrink instead of electrical tape. I didn't have any lying around and don't want to go get some. I have since added heat shrink.
If you have any other questions, please feel free to leave then down below
@Alex Suero-Amparo Sorry I missed this. The drill still works great today. We use it mostly as a backup when our main drill's battery dies.
Yeah not adding that to the video would make people assume you just used an ac power cord and went directly into the wall outlet. Not good on a 14 volt dc drill lol
@@ernieproductions7354 The drill will burn up and you might get hurt!
@@ernieproductions7354 Answer: What's your favorite flower?
@@JustinLodes So do you use the computer charger as a relay between drill n 110 wall outlet, or is the laptop charger used as a powerbank, n drill will only run until that is dead?.
Always make a knot in the cord on the other side of the hole (inside the casing) to keep your connections from breaking when the cord is tugged, and if you still have the dead battery don't even open the drill at all. Instead, carefully open the battery casing, remove the guts and wire to the casing so that you can have a cord that simply plugs into the drill. Not only is it a cleaner option but you retain the ability to use batteries in the future.
Thanks for the info. One thing though,,if the battery is dead and the charger is OK is there anyway you can connect to make it run on a 110v wall socket..?
Thanks for the tip. Bought a used drill with dead battery and will use your inputs
@@vishnudanraj2570 Not directly to ac, you will need to run it through an ac converter to dc, ac and dc do not mix together !
Nice video couple of pointers 1) use a really small drill bit to start and you will end up in the center then the larger drill bit will follow the smaller one. 2) solder your wires for better contacts. Nicely done
Thanks for the video. Now I can save that old drill, old computer power supply and battery from my junk pile. I think I am going to adapt another battery for wiring into my car's 12v accessory plug.
Thank you , you did great job explanation everything,
Nice job young man.keep it up
Did you remove the small black box from the mains adaptor! I did this conversion and it works ok until I pull the trigger right in when it turns on and off and on and off and I do not know why?
You are a great placed for all kind of great worked. I used to have a little peace but you got a bettered. Thank you
Did you look up the part number for the electric motor inside the dril8l?
Hi, lovely video and some great work. UA-cam find of the week for me. I bought a cordless drill 15.6v with no charger and the battery pack had 11, 1.2v 1500mah batteries Ni-Cd. 3 of the 11 batteries had zero voltage, the rest ranged from 0.2 to 1.1v. I want to convert the cordless drill to corded. Please I have an old laptop adaptor with output rated as 20v and 3.25A, would this be enough to run the drill, or what would be the ideal range of adaptor to use? Kindest regards.
In our experience, drills typically need a lot of currents (6-8 amps). It would also probably be beneficial to try finding an adapter with a voltage closer to the 15.6v spec of your drill, as having too high of a voltage can cause it to burn out.
@@DadandSonDIYHow quickly would the 20V 3.25A adptor burn out the to be corded drill? What old disused electrical product could I harvest a 15V and 8A power supply? Many thanks
@@DadandSonDIY Many thanks for your kind reply. Please I got the cordless drill for pennies without a charger, I do not mind experimenting with the laptop adaptor I already have, what might be the dangers to the adaptor 20V 3.25A or the 15.6Vdrill by pairing them up? Or not bother and wait and see if I find a closer matched laptop adaptor? What electrical items might I be able to harvest a usable power supply for the drill? Great stuff and kind regards.
@@michaelmercury1256 yard sales, that place that resales donated items Goodwill almost couldn't remember the name and of course online sometimes you can pick up a whole bunch of different adapters AC/DC. If you go to online route and you're trying to to do this for several items or to have backup supplies I would buy a assorted group of them in a one-time purchase where you probably get them for a dollar to a piece plus shipping. But you can go ahead and do a quick soldering up of what you have if you're only going to be running the drill briefly and seldom use you probably be just fine but if you plan on using it for several minutes at a time for an afternoon you'd want to make sure that you have something that's going to give you the juice you need(a) and within the usuable (v) spec.
Can I do that to my cordless drill 18volts to 220 outlet? The battery is already destroyed ( not Functioning)
what power supply were you using. Every dongle I've tried has surge protect built in and will not allow the drill to have any torque.
What's the power source at the backend??? A battery/AC DC adopter or some solar panel directly?
Did you need to match the positive/negative sides of the drill with the positive/negative sides of the adapter or is that not something that needs to be done?
reversing the connections flips the reverse switch. You'd just check that the rotation is consistent with the reverse switch when connecting.
I have ryobi one + impact wrench 18 v ...battery's are expired..now i want to run on supply which have 20.8 v 14 amp..can i use this supply without any risk?
Any polarity I should watch out for?
What power supply do you use to power up the corded drill?
i have a drill the battery is dead and i want to fix it like u by cable,mine is 20v 1.3 amp.how can i do it?
Thank you about this video. You are the best. I have one question. I have a cordless drill 12 V. Can I use a Power supply unit (atx) from old desktop PC for power supply? It has an output for 12 v, but I don't know if there will be enough amperes?
If you can't find any markings simply look up a comparable power supply unit with the same wattage from the same time period online and that should give you some specifications
You are a champ that was awesome
The 18V or 20 V can be done, where did you get such a high current adapter?
T Singh it is 15 volts 8 amps. It is an old laptop changer we had laying around.
@@DadandSonDIY You should have shown that in the video. Until I saw this answer, i thought you were using a 110 volt cord plugged directly into the wall, which would have smoked your drill and probably caused a fire! Perhaps even electrocuted the user!
many laptop adapters are 19 volts: Perfect size.
@@quicksilverhorseman2 Oh, come one man !!!
What DC adapter did you use,how many volts????
It has to be a DC adapter that has either the same specifications as the drill or tools or a little higher... If your drill says it needs 14Volts at 6Amps to run nicely, look for a DC adapter that may have 14,18, or 20 volts at 6amps... just avoid using anything way higher on amps because it will overheat your drill.. so look for something about the same Amps..
Personally, I would get a AC->18V adapter and then wire it to an expired battery. Result? You can plug this "battery" into all compatible tools.
That's a great way to do it. We didn't do that for this one because this drill was the only one using the type of battery. Looking back, there is much that could/should have been added to the video.
Keep up the good work, young man...
Thanks!
I tried this with DC adapter of 5V 2A and it didn't work. Batteries inside the device were 3 prices of 1.2V each, 1800mAh. No idea what kind of DC adapter I need but the one I tried didn't work.
As I saw your video it came to mind.. what if an old battery can be the one getting modified to the laptop adapter so you can use it in other cordless ROIBY gadgets.. because i have a ROIBY drill, 2 impact drills, a saw blade, a radio and a flash light... and they all use the same battery.. thanks for the video too man.. great one.
That's an interesting approach to this. It would allow the adapter to work with multiple tools. Thanks for the support.
@@DadandSonDIY you are welcome man. I just thought this may make it easier to swap the devices sharing the same input. If possible consider explaining a little bit about why the laptop charger and its specifications so they stop asking questions.. hehe and how the voltage and amperage are related to the tools you want..
Which adaptor is suitable for 12 volt black and decker drilling machine to work on AC? (Battery 12 v, 1.0 Ah)
You need 12-14v at 8amps
hiii good video! but u should explain what ac to dc power supply adopter should be use for 7.2v 14v or 18v cordless drill machine..
om jat Just try to get a power supply that provides the closest to the amount of volts to your drill requirements. It gave be a few volts off. Just make Shure it provides a minimum of 6 amps. The more amps it provides, the better. Good luck👍🏽
Well done mate!
Thanks, Benjamin!
How to find out the drill specifications can you give us an example? In this vdo you did not mention wat type of ac adaptor you used and wat is the output amperage how many amps do we need to run a drill?
dude, you can always check your drill specifications in google. make sure you type the make and model number of your drill. 👌
Im currently attempting to revive an obsolete ryobi 14.4v. Ive done a lot of my homework and searching around for others who have tried as well (and there weren't many!) To not blow anything and to have decent torque, Ill try using a 12v (goes up to 14.5v adjustable) power supply 30a thats used in cctv, led lighting, and other general purpose stuff, and put a 20amp fuse to keep things from blowing up.
Ive encountered a video where someone used the same technique but on his 18v dewalt drill, and safe to say he did not blow his 15a fuse.
@@amielrumbaua8387 find a power source that is the same as your drill ( 14.4v ), then add full bridge rectifier to avoid current loss.
or
you can just build a powerbank for your tool using 18650 + bms
Nice video... Thanks for making it. I have that same drill, except the battery is 18V. Can this conversion be done with a regular power cord, like a light duty extension cord rated @120v , 13 amps?
CATHERINE JONES definitely not. 120 colds will completely destroy the circuit and is dangerous. I used an laptop charger because it changes the voltage from 120 volts to 15. You will need some type of adapter for your drill
@@DadandSonDIY Mahalo! Keep up the good work!
I know this is an old post. But, we have a Kyobi and a Kawasaki that showed 18v and 19v on the power drills respectively. I hooked them up to a 12v, 6a car charger to see if they would still work. They had no problem going full tilt. So, a 12v power supply will be sufficient. However, the video says AC adapter, which means that it's going through a power conversion from AC to DC. This is because cordless drills are designed to work off of batteries that are well under 120 volts. As for amps, that gets drawn to the electrical device as opposed to volts that get pushed. As such, you can go as high as you want on the amperes. But, I wouldn't go any lower than 4 amps or your drill will struggle on tough jobs.
wow! beautiful, but the cable connections lost me, how do you know which cable colour goes in what pin?
Use a multimeter to determine which pin on the battery is positive and which is negative. If the polarity is reversed you’ll get a -18v dc or -12v dc reading
I conected same charger that the drill came with direct to drill .however the drill runs far to slow to be any use ?
You need to check the amount of volts and amps that the charger provides. It needs to have at least 6 amps to be of any use and should provide a voltage similar to what the drill is rated for.
The charger just trickles electricity into the battery, it can't supply enough to power it, check the amp rating of the power supply. when freewheeling the drill pulls about 3 amps and when working it can pull up to 10.
My cordless drill is 14.4v. How many volts and ampers of adaptor or charger i need to use?
You will need an adapter that can output around 14.4 volts (+/- 2-3 volts should be fine) and around 6-8 amps.
Great tips! Will apply them on a bunch of old drills that I have.
Thanks. Happy to help.
Are you still there bro. One thing, if the battery charger is OK which output 24v can it work to run the drill which is 18v
Thank you very much for the vid.
Nice video, got a similar project I'm involved in now. The power on mine would be from a car 'cigar lighter' power outlet.
U may want to run straight from battery as the circuit for the lighter might overheat and or blow fuses
How many amps do i need if my battery specs are 18v and 1.3 ah? Also where can i find a charger with that hight voltage?
read the label on the rechargeable battery or take a photo and search on google what adapters deliver that current. Then if its something accessible you can probably go to like a Goodwill or Thrift Stores and check their cables bin maybe you may find something to what you need.
A/c direct from d/c ??
What os the power of powersupply? 18v about Amos?
It is 15v and 8 amps. The drill ran off of 14v batteries.
What did you use for a power supply what did you plug the cord into
its a laptop charger. It plugs directly into the wall.
advise full specs of your laptop charger.amperage,AC input voltage,DC output voltage etc...full specs of your laptop charger please. Thanks.
You can send your full spec of the laptop charger to my email..jenjubo@gmail.com..Thanks.
@@DadandSonDIY when i do this my motors just pulse please help lol
reikhavok you need to increase the amount of amps it receives. Most drills require 6-10 amps. I went with 8 amps.
Mine just started skipping. It turns a bit approximately every second.
I'm using a tesco drill and a 12v 2amp laptop charger. The original battery was 1000mAh.
Any suggestions?
I would replace the current laptop charger with one that can output more amps. I had that issue when I first used a 4 amp charger and increasing it to 8 solved the issue.
@@DadandSonDIY you were right. I replaced the 2 amp laptop charger to a 10 amp car battery charger. Now it drills like crazy.
Thank you! 😁
@@r3unite749 My pleasure!
can i use 18v battery in 14.4v brushless drill????
It definitely isn't recommended. Doing so can kill the drill or at the very least reduce its lifespan. In the video, I used a 15v adapter for a 14v drill, so they matched up pretty well.
On a different note for those of you who don't mind conversions, is a process that could be used on devices that would typically require two or more AA, AAA,C,D, etc batteries. For instance, I have a multi LED round riser that I think was originally for Illuminating a little toy from the bottom side up and I wanted to use it on the bottom of one of my fiber optic Christmas trees for which the original motor and color wheel with halogen bulb has gone missing. But battery's probably won't last but a few hours in it and you can get expensive to swap them out and very time-consuming to constantly be charging them up even if I did have a good Supply. All you have to do is take the number of cells and if they're 1.5 volts and in this instance I'm looking at 6 volts DC(4×1.5) and knowing it's just for some low wattage LEDs I'll just take one of my AC/DC adapters( and I keep all my old ones even for items that quit working) and I'll find something between 5-7 1/2 volts DC at probably 500 milliamps plus or minus to power it and it'll be soldered in at the two main leads off the battery box or I'll just remove the leads from the box and go off of that and then you just plug it in when you don't want it unplug it and you don't have to worry about it
Yes but hiw you conect it
Will you explain from where the supply is come for drill and how many volts?
Francis Xavier Fernandes the power comes from an old laptop charger. I cut off the end of it. It provides 15 volts, and the drill needs 14. If you also try to use a laptop charger or something similar, make sure that it provides 4-8 amps because most drills demand it. Good luck👍.
The AC Adapter Ampere is?
can i use the own rechargeable adapter ?
I don't think so, rechargers charge batteries at a higher voltage than the battery. So if you have a 12 volt battery, to charge it would require a higher voltage.
can you do this and still allow for the battery to be used when desired?
Not the way I did it.
@@DadandSonDIY yeah, not the way you did it but it could be done right and shouldn't have any problem? I'm thinking about getting a battery powered miter saw for those times I don't have AC but I'd like to make it a corded saw too
@@MysteryScienceGaming You could build an adapter that fits into the saw the same way the batteries do. That way, you don't have to modify the tool and can switch between running the saw off batteries or a cord.
@@DadandSonDIY good idea, do you think I should take battery I have that is broken and use it as my adapter?
@@MysteryScienceGaming If you have a broken battery, that would be a great way to do it!
Why do you not show the connection to the electricity.how you connect.?
Tried Toshiba power supply 15v 5amp to run a Skill 14.4 and it ran very slow. Put on a 12v car battery with car running and ran faster with no loss of tourqe. Must have been to old a power supply.
Hmm, that's interesting. Glad it worked out though!
A 12v car battery can output on average 40 amp hours or more which is why the battery worked better.
Should use a center punch before drilling so the bit stops sliding all over the place.
I agree
or just solder it to it.
I used a 12v 12ah battery out of my childs ride on car (actually just a 12v golf buggy/mobility scooter battery) to power a bosch drill in a fix. Just used crocodile clips on each end. A bit sketchy, but it worked great. That's another option, carry a bigger battery with you and wire that into your drill. If you can wire it into an existing battery, even better!
wait so I need a drill to fix my drill ^^
xzibit would be proud
warping wire and taping is ok for testing , but final solution should be soldered or crimped , and a knot should have been tied on lead before it came out of drill for strain relief
But why a cordless use power supply but a corded one is used without a power supply?
If the cordless tool is for example 400 W 20V batery, this means a power adapter that outputs this power is 20 V, 20 A, because 20Ax20V=400W.
That would be a very powerful tool. Our drill was only 14v and ~8amp. I'll let you do the multiplication ;)
@@DadandSonDIY Usually cordless tools are not so powerful to spend energy. Actually manufacturers don't let we know what power they need to get working, so we need to open the tool and read the motor specs or find their default power consumption on internet. My example was only to make sense. So when a motor works it consumes more power if the power adapter can supply it. The voltage of the adapter should match the battery requirement, but it can provide more power, the motor will take no more power that it needs, if it is used correctly. If the motor is under pressure it can consume more power and to burn out. The upper limit of the adapter's power is for security reason, because users sometimes don't use the tools correctly.
This also works if you want to try out whether your cordless drill works IF you have dead batteries. Connect just as the kid did here (Caucasian to Native-American & African-American to African-American). Put some electrical tape on the connections, fit the trigger in back into the plastic harnesses so you can try it out to see if the motor works.
🤔🤔🤔🤔🤔🤔

Begin drilling your hole then add oil to avoid slipping and getting a wonky hole, also use a centre punch and hammer they are cheaply available and will up your quality in your work.
Your commentary instead of being a suggestion of improving the work shown here, rater it seems a caustic negative opinion. This guy tries to show an idea that in my point of view is very good. In my opinion, I would remove the battery pack from the case , and I would use the battery case. I would sold the adapter's wire to the connector terminals of the battery case. then, I would install the power directly like the drill has the battery. I wouldn't open the drill. I think he shows a good idea and my battery charger and batteries are broken.
Hi would the drills original battery charger unit work as a power supply?
Thanks
It might. You will have to check the voltage. In out case, the charger wasn't able to supply the right amount.
Thanks for reply unfortunately in my case the charger wasn’t up to the job tried a 12 volt car battery charger (6 amp) which did work but as drill is 18 volt lacked a bit of umph although it only drew 3 amps from the charger. Pity there isn’t an easily available 18 volt power supply that could deliver the required amperage, any suggestions?
Anyway thanks again and keep those videos coming like the Dad and Son concept by the way!
I have found lots of 19.6 volt laptop chargers. I know that's a little bit more than what you are looking for, but it should be close enough.
Hi I’ve found a 20v 4.5amp laptop charger on eBay so will give that a try!ill let u know how I get on thanks again.
How did it work Paul? I have a 12 volt drill and when I connected it to a 12 volt transformer with low amperage the drill pulses under load. I think it needs more amps. B.L. Alley (above) is recommending up to 10 amps minimum. Does 4.5 amps provide enough?
Can I run an 18v drill off an 12v powersupply?
If so, what will be the effect of the reduced voltage?
Thank you
It will be much weaker basically. Maybe, very maybe, it will draw more current and burn up? But I think likely it's just gonna be weaker.
@@millanferende6723 thank you, much appreciated
@@tonysicily2687 No problem! Just to clarify myself because otherwise I will feel stupid:
99% chance it will just be much weaker.
@@millanferende6723 You have been very kind
I have converted several 18V tools to run off 12V without any loss of torque. The unloaded speed is a little slower, but not enough to notice. The reason it works is that I'm using a regulated 12V high current (30A) supply. Battery voltage sags under heavy load anyway, so 12V is plenty. I measured tool current and voltage under load before and after battery elimination.
Good work but mine won’t run
So your telling me you just plug that too the wall how you convert it from 110v down to 18v😮
Should have tied a knot so the cord does not pull out from the inside. But still a great video
Hi again
So you mean to tell me you have the drill plugged directly into your home outlet?
No, there is a laptop charger that we used as an adapter. DO NOT plug the drill directly into an outlet as the drill isn't meant to run on 120v AC.
@@DadandSonDIY: Let him plug it in to the AC. Some of the queries to your excellent post are from people that should not be playing with AC/DC in the first place.
Please make hand driller charger
Please
Question...does it matter which is positive and which is negative??
It does most of the time, but for the drill, it probably doesn’t since it will just make the motor run in reverse.
Observe polarity.
Of course it does, in DC world - / + are very important !!!
Or you could just use the 12 v battery drill to car battery.
I tried it, but my arm got so tired with the car battery taped to the bottom of the drill...
@@markm8188 Great comeback!! This comment made my day, Thanks for the laugh :)
Incomplete, I think, for a beginner. why u didn't show the other side of the connected cable?
I was young when I made the video. Looking back, there is a lot I would change in the project. Still some cool ideas there though!
@@DadandSonDIY oh. I see. Could you share those recent ideas? I have one, don't want to throw.
@@p.c.rpendyala9044 Instead of attaching the wire to the drill, modifying the tool, you could attach it to the battery connecter, removing the old batteries, so then the old battery housing is essentially an adapter for all the tools you have.
@@DadandSonDIY Tks. Let me try. .... I am not a techie. Trying to understand this reply.... I yet to start my exploration....I was thinking if using so many old adapters, lying around... Can I cut the charger adapter connection at the battery holder and connect the ends as suggested in the video. My understanding this is what u are suggesting now.
Nice but you should explain what ac to dc power supply adapters should be used. you won't want some idiot to just put a plug on and plug it in. Please think it through!
Why not soldering wires to the pines ??? Much more safer.
Back when I made this video I didn't have a soldering iron. You are right, soldering would result in a much better connection.
People are so creative in those developing countries.
Since when is America a developing country?

Thank you and I (vary "old") called a great smart to wonder always. I say in my word "SHALOM" (in my own)
This is the easiest part you literally just get a power supply and put it around the contacts. This is t the problem people are having. The problem people are having is getting the/a power supply with high enough amps without paying more that a brand new drill
You’d have to be brain dead to not know how to do what you did
I didn't know and I am not brain dead, I just not into electric parts and this advice was gold to me. I use a drill once a year, my work is into the accounting field I know nothing about connections.
you don't even show what power supply you connect it to... won't work under 6-8amps under load.... so this vid is prolly bs.
Why are all you drill converters so dumb? Just remove the battery, put it in a drawer and forget about it and attach the wires to the terminals up inside the handle, job done and in half the time!!
If you think you're so smart and everyone else is dumb, you're probably the one thats dumb.
Hey Genius. You left out the most important part of the conversion - the POWER SOURCE. Unbelievable that no one has commented on that here. I'm really concerned about the young generation these days. sad.
My partner has a lot of tools, so when he needed a circular saw, I ordered this one for him as a Christmas gift. ua-cam.com/users/postUgkxYDKeIjKLOfcwTgdin7TtCutsz4MbIc43 He is incredibly happy with the purchase. He stated that he likes that it is powerful, but still easy to use and cuts very well. He mentioned that it is important to know the right tools for the job at hand, and this compact saw has been exactly what he needed for a variety of projects at his rental properties and renovations. He also appreciates the battery packs, as stated, he owns a lot of DEWALT tools, so he is able to always keep batteries charged as needed.
