A new programmable adapter is allowing tech enthusiasts to power legacy electronics using modern USB-C batteries and chargers. The device, called the VFLEX and made by Werewolf, functions as a small dongle that bridges older barrel jack power ports to contemporary USB-C standards without requiring any physical modifications to the vintage equipment.
The adapter works through a simple process: users connect it to their smartphone to configure the appropriate voltage level, then attach a barrel jack tip suited to their specific device. Once programmed, the VFLEX can draw power from any USB-C source, from portable batteries to wall chargers. This approach enables users to power everything from classic gaming consoles to professional recording equipment and desktop monitors using the same modern power infrastructure.
The practical advantages are substantial. A single portable battery paired with multiple VFLEX adapters can simultaneously power several older gadgets for extended periods. Because vintage electronics typically consume minimal power compared to modern devices, even compact USB-C batteries can run them for many hours. The system negotiates appropriate voltage levels automatically, allowing users to safely mix devices with different power requirements.
The VFLEX costs approximately eight dollars per unit, with additional barrel jack tips available for four dollars each. Users must program each adapter before use to prevent accidentally supplying incorrect voltage to sensitive historical equipment, though the device stores these settings in permanent memory for future use.
