Crooked Finger Designs has a long history of designing and installing off-grid electrical systems for rigs. We do large systems, and small systems, but our specialty has always been systems for the rigs that go the distance: westfalia’s loaded for full time living, beefy land cruisers and compact overland rigs, vehicles where performance is paramount, and every square inch of space counts.
After years of designing and installing custom systems for dozens of customers and rigs, we took on the challenge of distilling these systems down into the best possible system, in the smallest footprint we could manage.
The Box is more than just a mobile charging station for your phone and fridge, this is a fully functional 12V auxiliary power system for your vehicle or camper, built to the same high standards we utilize for our custom installs. It includes a top-of-the-line lithium battery plus all the charging, monitoring, and fusing that we typically install in a custom installation.
The crooked box is built in a tough powder-coated aluminum box with aircraft grade hardware and an easily removable access panel making the entire system serviceable.
