Introduction: Power Supply for My Cordless Tools.

It happens that there is very little left to do, but the battery died . Waiting for charging could take half an hour or even longer . This is why I made an additional power supply for my cordless tools

Parts List

NEUTRIK NAC3MPX

NEUTRIK NAC3FX-W

AC/DC power supply 90V~260V AC Input, Single Output 500w 18v

Tool Box

DC 0-30V 0-50A Red Blue Dual LED Digital Voltmeter Ammeter Voltage + Shunt

Plastic Case For DeWALT 18V Battery DC9096

If I to change anything about this set up it is the size of the tool box.
The one I got is 6.5" x 7" x 15" and it is a little crowded with the 18' long power cord coiled up inside of it

and possibly splice the power cord with a power connector right at the battery, so if I need to power up a 12V tool I could simply swap a battery with a step down housed inside of the battery/adapter case. The hardest part of the whole project is the search for the 18V power supply which can produce 20A +

A simple change to the power supply makes it usable across the full range of 18V power (cordless) tools https://www.youtube.com/watch?v=lD69XLxYX_k

Where did you buy the AC 220 to DC 18 volt 20amp inverter & the cost?

Thanks

got it from http://www.aliexpress.com/

A fantastic video and instructable. The perfect example of why I love this site. Thank you.

Very cool. Thank you for sharing your video (and for including translated subtitles!)

Thank you! I'm glad you like this solution.

Great upgrade. This would come in handy for long jobs that require a lot of tool use. How long is the cord that goes from the power supply to the drill?

I use some of this cable to do the wiring inside of the tool box. So the total length is 18' from the tool box to the power tool
