Attention: the Power Supply Jack is a 5.5mm x 2.5mm type. So you need a power supply with 5.5mm x 2.5mm plug too (a 2.1mm variant which is also often sold wont fit). Ideally search for following term on amazon or ebay: "12v power supply 2.5mm barrel plug" or "12v power supply 2.5mm barrel connector"

This is a 3D printed 20V and 1A laboratory power supply.

I made it because i needed a very lightweight and portable power supply and maybe you need one too.

It is special because it is 3D printed and uses a SMPS instead of an iron core transformer, which makes it weigh only 0.3 kilograms.

PRODUCT PARAMETERS: Maximum allowed output voltage: 20V Maximum allowed output current: 1A Size in mm: 92x81x67

This power supply is based on the ZK-4KX power supply module. In its current configuration the power supply can supply 20V and 1A, even though the ZK-4KX module itself could deliver higher voltages and currents (it would need a huge heatsink for that). I have set the current and voltage limits to 20V/1A and tested the unit with these settings, do not change the limits to higher values than that!
