Mean Well 5V 4A 20W Power Supply (GST25A05-P1J)

This is a 5V 20-watt power supply, providing a 5V 4A output via a 2.1mm DC barrel jack connector (centre positive). It is part of the latest GST range from Mean Well, improving on the previous GS range and now meeting Energy Level VI requirements, Datasheet available here.

Ideal for providing a solid 5V power source for your projects, you can easily break out the connector using a Barrel Jack to terminal block adapter, power your Pi Zero 2 with our Barrel Jack to Micro-USB adapter, or even a Raspberry Pi 4 using our Barrel Jack to USB-C adapter. The generous 4A output makes it ideal for all of these scenarios.

The unit has a standard IEC ('kettle style') input. An IEC cable is not included with the power supply but we offer a range of options in the store:

• UK IEC Cable
• EU IEC Cable
• US IEC Cable
