As we all know about the merits and demerits of corded and cordless tools. Both are versatile in different circumstances. Again, both have few disadvantages too in terms of power supply, portability, convenience, heavy or light duty features and some occupational hazards.

However, when questions are raised regarding technicality for making a cordless tool to corded tool, I can say from my personal experience, it’s pretty easy to convert your cordless to corded tool and vice versa following a few simple steps. Moreover, it neither costs much nor consumes time. It’s all about your convenience as to which model you would feel comfortable to work with and why.  

As we know cordless tools have some limitations. Then why should you take so much stress with its battery life, charge level and/ or charging battery postponing your work? Also its heavy battery pack could cause you extreme hand fatigue and boredom. 

Considering all these aspects I have designed my article on how to make a cordless tool to corded. You just need five minutes to finish reading this article.

Steps for Converting a Cord Tool to Corded

The first step is to define the voltage (V) and current (mAh) of the tool you are converting from battery mode to a power adaptor. It can be called conversion of cordless tool to corded tool. All you need is to assign the power adaptor to the slot of the battery where batteries contact inside the tool. Let’s go through the process to understand the conversion from cordless to corded tool. Don’t worry. It’s a pretty simple process and almost a zero cost project. 

Things You Need for Conversion

  • Adapter;
  • Electric tape; 
  • Multi-meter; 
  • Extension cord;
  • Pocket knife;
  • Wire strippers;
  • Electric tape;
  • Aluminum foil or other conductive, flexible material (Optional); 
  • Drill (Optional)

Determine Volts of Your Tool Estimate

The first thing you have to do is to check out the number of batteries used for your tool. Standard dry-cell round battery AAA, C or D etc. is of 1.5 volts. Now you just multiply the number of batteries with the volt 1.5 to get the value of volts you need for your AC adaptor before conversion. If the number of batteries is 4, it means the total volts your device uses is 6. In the case of 6 batteries, just calculate it the following way. Again, for six batteries the total volts will be 1.5 volt x 6 batteries is 9. 

Determine MAH or Current Rating

You can find the current rating somewhere printed on the body of your tool or in the user’s instruction manual. The adapter you are going to use for conversion needs to be matched with the battery operated current ratings. It won’t matter if the rating of the adapter is higher than the value of the battery operated tool as the converted tool will use the current from the adapter as it requires. 

Get an AC Adapter as Per Voltage and Current Ratings Measured

Get an AC adapter if you have extra at your home or buy one from the market based on the value you have already determined in terms of volt and mAh

Quick Task at Battery Chamber

In this step, you just disconnect the low-voltage connector located at the end of the adapter’s wires. Take out around a half inch of insulation from the last point of the wire and separate the wires about four inches to five inches. 

Connect Adapter’s Wires Inside the Battery Chamber

Now the time is to connect the adapter’s wire for replacing the wireless mode. To do so, you first have to find the neutral wire of the adaptor. Neutral wire can be recognized by its white stripe or raised strip located in one of the wires. However, with any electric tape or solder connect the neutral wire to the negative slot located inside the battery chamber. Just remember, connect the wire on the slot of the battery chamber where the two wires are separate that you already checked out in the previous step. 

Now take the positive wire from the adapter and join it with the connector located inside the battery chamber where the nub of the battery or wire can smoothly enter. Again, join the wire of the adaptor to the side of the battery chamber where the two connectors are separate as you did earlier.  

Test the Conversion and Wrap Up Your Work

After completing the conversion process, check out all connections, test your tool with the multimeter to ensure that the conversion is done successfully. You also use extension cord to test the proper power supply into your device through it. 

Additional Tips

Wear your safety gears like hand gloves, boots, goggles, jackets, ear gear, etc. as appropriate to avoid injuries and workplace hazards. 

Visit different sites, read articles, watch videos related to your project to accomplish your work more efficiently and advance your learning.  Get associated with professionals in the power tool industry, clubs and training institutes to continue your learning and sharpen your skills.  

Final Notes

Though it’s a pretty simple job to convert your cordless tool to corded tool, as it deals with electric work, you must wear all safety gears to prevent accidents that may occur from electric short circuits. 

I hope you will enjoy reading this simple, short and precise article. You may try this project at home or workplace on your own to learn by doing. Always get associated with professionals who work with the power tools to advance your knowledge and expertise. 

I would love your comments and feedback so as to be able to serve you in a more efficient and effective way in the coming days. One more request, please share this article and our site with your family and friends so that we can optimize our services to meet their needs and expectations. 

Good luck for all of you and stay safe during these corona pandemic days. Maintain safety protocol to be protected from all kinds of health hazards and encourage others to do so.
