12V Outlet with LTC3780 boost buck converter for camper

thingiverse

This nifty gadget is a versatile power adapter and outlet combo. It's a straightforward 3D printed case that accommodates a LTC3780 module, a toggle switch, and a standard car or marine power outlet - also known as a cigarette lighter socket. Its design allows it to be printed in three parts and mounted on a wooden panel. The concept is to utilize this setup to power your electronic devices instead of an inverter. Employing DC voltage is more efficient than AC when the appliances you want to use only require below 30v DC. Why incorporate a LTC3780 module? This module functions as a buck boost converter, capable of regulating voltage both upwards and downwards. This means that if the source voltage varies - such as when a solar panel charges a battery or an engine recharges one - the voltage can spike to 14v+ or dip below 12v, potentially causing issues with small appliances that won't tolerate these fluctuations.
