DC-DC step UP (used as a 19V in-car laptop charger)

thingiverse

I had to get a charger for my laptop in the car, so I picked up this standard DC-DC step-up voltage regulator that converts the 12-14 volts from the car into the 19 volts my laptop needs. I kept the heatsinks flush with the outside of the box, which reduces cooling slightly but works fine for me. This also prevents sharp edges on the heatsink from scratching the interior of the car or my own hands. A quick Google search shows this DC-DC converter: https://www.google.com/search?q=dc-dc+boost+converter+150w&tbm=isch Tie the two cables together with cable ties on the inside. If necessary, you can seal the lid tightly by applying a small amount of glue.
