About this product
An unregulated AC-to-DC adapter with a 100-240 V mains input and selectable outputs from 1.5 V to 12 V at up to 1200 mA. It includes five interchangeable connector tips and selectable polarity, making it suitable for small appliances, toys and hobby electronics. Because it is unregulated, the output voltage changes with the load.

Frequently asked questions
Can I use this adapter for sensitive electronics?
Not directly. The output is not regulated, so its voltage rises at light load and drops under heavy load. For microcontrollers or sensitive circuits, add a regulator module after the adapter.
How do I choose the correct polarity and voltage?
Check the label on the device for its required voltage and the polarity of its barrel connector, then match both before connecting. Connecting the wrong polarity can damage the device.
