How to Make A Cordless Drill Run Off Of An AC Adapter 

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

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.

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

Thank you , you did great job explanation everything,

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.

Nice job young man.keep it up

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?

Did you look up the part number for the electric motor inside the dril8l?

Any polarity I should watch out for?

Hi, lovely video and some great work. RU-vid 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.

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

What power supply do you use to power up the corded drill?

What's the power source at the backend??? A battery/AC DC adopter or some solar panel directly?

Can I do that to my cordless drill 18volts to 220 outlet? The battery is already destroyed ( not Functioning)

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?

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?

The 18V or 20 V can be done, where did you get such a high current adapter?

What DC adapter did you use,how many volts????

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.

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?

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?

Yes but hiw you conect it

I conected same charger that the drill came with direct to drill .however the drill runs far to slow to be any use ?

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?

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.

wow! beautiful, but the cable connections lost me, how do you know which cable colour goes in what pin?

My cordless drill is 14.4v. How many volts and ampers of adaptor or charger i need to use?

Great tips! Will apply them on a bunch of old drills that I have.

Which adaptor is suitable for 12 volt black and decker drilling machine to work on AC? (Battery 12 v, 1.0 Ah)

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.

What os the power of powersupply? 18v about Amos?

What did you use for a power supply what did you plug the cord into

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.

Keep up the good work, young man...

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..

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?

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.

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?

A/c direct from d/c ??

why is mine tripping the breaker?

The AC Adapter Ampere is?

can i use the own rechargeable adapter ?

can i use 18v battery in 14.4v brushless drill????

Well done mate!

can you do this and still allow for the battery to be used when desired?

You are a champ that was awesome

Why do you not show the connection to the electricity.how you connect.?

Should use a center punch before drilling so the bit stops sliding all over the place.

Nice video, got a similar project I'm involved in now. The power on mine would be from a car 'cigar lighter' power outlet.

Will you explain from where the supply is come for drill and how many volts?

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.

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

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.

But why a cordless use power supply but a corded one is used without a power supply?

Hi would the drills original battery charger unit work as a power supply? Thanks

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.

Good work but mine won’t run

Can I run an 18v drill off an 12v powersupply? If so, what will be the effect of the reduced voltage? Thank you

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

Question...does it matter which is positive and which is negative??

So you mean to tell me you have the drill plugged directly into your home outlet?

Hi again

Please make hand driller charger

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.

Or you could just use the 12 v battery drill to car battery.

So your telling me you just plug that too the wall how you convert it from 110v down to 18v😮

Incomplete, I think, for a beginner. why u didn't show the other side of the connected cable?

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!

Why not soldering wires to the pines ??? Much more safer.

Should have tied a knot so the cord does not pull out from the inside. But still a great video

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!

People are so creative in those developing countries.

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

After checkingued plenty of other nice ones of "so closed" used to changed from battery to real electric used, I am 100: vest is yours to easily done. As the so called "seam" different priced companies and pretendingued onliest when in reality hare just playingued to united when in reality in my finde that basically all can start same thinned system, In my winded you hare the greatest of all showed for most great for those liked me to find the systemingued to dined. Thank you and I (vary "old") called a great smart to wonder always. I say in my word "SHALOM" (in my own)

You are very smart

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!!

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. ru-vid.comUgkxYDKeIjKLOfcwTgdin7TtCutsz4MbIc43 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.
