Maker Slurpburgers built Slurptop around a Ryzen 7 7730U mini PC with 64GB of memory, a 14-inch display, a mechanical keyboard, and a trackball. A buck-boost circuit adapts a 24V power-tool battery to the PC’s supply voltage, while a UPS switching module transfers between battery and external power. The enclosure uses 3D-printed parts and aluminum reinforcement. The maker reported more than four hours of light work on a 4Ah battery; approximately five hours is an estimate. Charging requires a separate charger, and batteries are not hot-swappable, so external power is needed to keep running during a swap.
