Here's how to get the power from your car battery or another direct current (DC) power source to your 18 volt Dewalt power tool. Please keep in mind that my reason for even doing this was due to the times my battery died when I had no way of charging it while out on a job in the middle of nowhere. With this technique, you can use any extension cord but the thicker the wire the better - a contractor type cord is best. Just don't plug your cordless power tool into 110 volts by mistake! Always install a fuse as close to the battery as possible to prevent damage from short circuits. The extension cord system shown also has many other uses allowing you to bring 12 volts anywhere you want and limited only to the length of your extension cord.

  • correct me if im wrong but isnt the NATO adaptor on that truck 24 volt? it looks like a CUCV if im not mistaken

  • @kcanifuku Yes you are correct on both areas. The truck is a 1986 M1008A1 CUCV with the 24 volt NATO Plug on the front. When using a long extension cord, the voltage drops down because of "resistance" and the voltage is perfect to run my 18 volt Dewalt tools.

  • the drill isnt running slower because of the long cord, its because its an 18v drill and you're feeding it only 12v

  • Right you are! Most of the time I hook into my NATO plug that you see in the front of the grill and the drill runs considerably faster. When I made this video I had not finished making my "cheater cord" for the NATO plug but in one of my other videos you will see it in action.

  • I thought about doing this to an old 12V power drill where the batteries were failing. I was gonna completely gut one of the batteries and wire up a thick 12V car lighter cord with maybe a 30 amp fuse or whatever and the result would be a cord running out of the drill battery and you just plug that into a jumpstarters 12V port or a car lighter port and then you have unlimited power for the drill. sadly I didnt do this and just got a RYOBI 18 volt.

  • The 12 volt batteries that I have for my Dewalt cordless tools are hermetically sealed shut - not like the 14.4 and 18 volt units that "unscrew" to access the cells inside so I have not attempted to convert one of the 12 volt batteries just yet. Interesting enough, the 12 volt batteries seem to be made better and outlast the larger voltage ones for some reason. I had a totally dead 12 volt battery that took on a full charge after sitting for years without use.

  • @bernard240vdc While that would work, motorcycle batteries make a poor choice as they do not hold up to repeated discharging. In fact, in my experience after 2-3 discharges they are typically ruined. Now one could watch the voltage and make sure they are not discharged but that would be annoying or use something like a gel battery that can withstand that type of work.

  • Good luck not blowing yourself up. Make sure you make a video every time you do this cause I want to see you learn your lesson.

  • @WhatM3Worry How could you make your own packs for drills? I worked on a shed last year and could've used that trick. Thanks for the tip in any case.

  • along with this good setup one could use motorcycle batteries one 12v plus one 6v in series for 18v along with a short cord and you can bring the motorcycle batteries along with you since they are not too big and heavy and i think they are not expensive as those dewalt ones

  • Is that UTP cable you're using to create the high resistance in the wire? It hasn't burnt out from the high current?

  • @aboonski Hello and regards from Germany..You should tell in your video that you have 24 volts in your car.People might think they could recharge their 18 volt batteries from an ordinary 12 volt car battery. Stefan
