Digital and Electronic Device Design Aurzen Zip Tri Fold Portable Projector by Aurzen Design Team Aurzen Zip is a tri-fold portable projector. The Z-shaped body folds into a compact form measuring 84 by 78 by 26 millimeters, allowing the projector to fit into a handbag or backpack. Two high-strength aluminum hinges let the height and the projection angle be adjusted without a separate stand. One-click screen mirroring works without Wi-Fi and supports iOS, Android, macOS and Windows. Time-of-flight autofocus and vertical keystone correction keep the image sharp. The built-in battery lasts up to 1.5 hours and supports fast charging.
