Hi there 👋,

A few months ago, I transformed a 22 amp car battery charger into a compact custom-built charger inside a Festool Systainer T-LOC !
I created a small youtube video out of it to show the build process. Feedback would be very welcome from Festool owners fans 😉

Here is the video:


And some pictures attached in bonus.

I watched the video mainly because I find the phenomenon of the Systainer very interesting.

There are probably 8 or 10 manufacturers out there that have jumped on the Systainer bandwagon.  Milwaukee, Craftsman, Kobalt, Stanley and Rigid come to mind, and I am sure that there are others out there.  They make a good stab at matching the Systainer’s functionality, but they fail to generate the passion and ingenuity that Systainers engender.

I have been watching videos (like this one) for clues to what sets the Systainer apart from the rest of the pack (pun intended).  I have not found it yet.

I was never going to replicate this charger-in-a-Systainer project, but found it interesting.

I would make a few observations, only the first references functionality.

You have provided far less ventilation than the original did.  I do know that my charger can get rather warm.  I am concerned about the adequacy of the ventilation and possible overheating.  A simple way to address this is to add a computer cooling fan (generally under 5 watts draw, and virtually silent) to the inlet, and providing an outlet vent across from the inlet.  I would not want to drill so many holes as to compromise the strength of the Systainer.

I would note that a brad point bit would be ideal for this type of drilling as they do not drift, though you did a commendable job maintaining spacing with the conventional bits.

I would note that I received a Bosch conventional drill bit this morning from Amazon.com and the packaging listed that it would not wander (“No skate tip”) and examination of the tip shows that it comes to a point instead of the typical flat.

A few notes on the video itself.  The video imaging seems highly professional.  I would add a preface showing a list of tools, especially specialized tools like the 3D printer.  Also, specialized skills like drafting for the drilling patterns.

And finally, I would challenge you to more tightly edit this video.  I think you can edit out 4 minutes of video without compromising the clarity.  For example, you could show one screw being removed and then show a pile of removed screws rather than showing each screw being removed.

I doubt that any owners of the other brands of “Systainers” would have endeavored to take on a project like this.  I am still trying to understand why Systainers command this elevated interest and none of the other brands seem to manage that. 

In any case, a clever idea and nicely executed.  A quality video too.
 
I keep my car battery charger in a systainer aswell, but I just put the whole thing in there  [big grin]

The outside looks very nice, it would really finish it off if you could make a shelf/cover, so you can store the cables under the lid without  them being in between the components.

Or cord spools that latch onto a stud inside.  A very tidy package.
