The [FIT0537](https://www.digikey.com/en/products/detail/dfrobot/FIT0537/9490135) Magnetic Mixer from [DFRobot](https://www.digikey.com/en/supplier-centers/dfrobot) does not include any power supply. Per the datasheet, the recommended power supply is “Wall Adapter Power Supply 12VDC, 1A (American Standard)”, but no plug dimension details are given.

Confirmed by DFRobot, the DC plug dimension is 5.5mm x 2.1mm (0.22x0.08"), with positive center.
