Universal Power Supply Goobay 53997

The Goobay Universal Power Supply 53997 from WENTRONIC is an indoor AC-to-DC adapter that delivers selectable output voltages between 3 V and 12 V with a maximum output power of 18 W (1.5 A). Designed for compatibility with a wide range of small electronic devices, the unit includes one USB port and eight interchangeable DC adapters, a 1.8 m cable and a compact black housing measuring 51 mm in width and 82 mm in depth. The wide input range of 100–240 V AC makes it suitable for use in different countries without additional converters.

Advantages

The universal adapter supports multiple voltage settings to match various device requirements and includes a set of DC tips to avoid the need for separate power bricks. Its integrated USB port adds flexibility for charging or powering USB-powered devices. The compact dimensions and 1.8 m cable simplify placement and cable routing while the enclosed design provides a neat, single-supply solution for desks, audio equipment, routers, small appliances and other low-power electronics.

How to use

Choose the DC tip that fits the device input barrel or connect via the USB port for USB-powered devices. Set the output voltage to the required level within the 3–12 V range before connecting the device. Plug the adapter into an appropriate 100–240 V AC mains socket and verify correct polarity and voltage on the target device. Ensure the device’s current draw does not exceed 1.5 A and avoid prolonged operation near the adapter’s maximum load without adequate ventilation.

Usage recommendations

Select the exact voltage matching the device label and double-check the tip polarity. For devices that require more than 1.5 A or have sensitive electronics, consult the device documentation and consider a dedicated power supply. Keep the adapter in a ventilated location and disconnect from mains during extended inactivity or maintenance.
