DC 5V 5A Power Supply, PHEVOS AC 110/120 to DC 5V Universal Switching Transformer Adapter for Raspberry PI Models, CCTV, Radio, Computer Project, LED Strips Pixel Lights

The voltage is adjustable and has sense leads, so you get 5.1 volts at the load. You will need some USB female connectors if you do not want to hard-wire the power leads to the Pi or shield. You will also need a line cord (and switch so you wont have to unplug from the wall).

Works great on my Voron 2.4 r2. I'd been running off a USB-C adapter for years but with the Pi HQ Cam and Pi 7" touch screen both pulling power, the thing was always under-volting. With this (turned up to 5.08 V) and 18 AWG wire feeding both 5V pins and two GND pins I was finally able to keep the rail at 5 volts! I created an adapter plate to be able to use the meanwell RS-25 DIN mounting clip that the Voron design supplies with this unit's mounting holes. You can find it on Printables if you need it.

I bought this to power an Android TV box with two 5 volt DC USB portable hard drives attached. The power supply that came with it is rated for 2 amps at 5 volts DC and has enough power to run one hard drive but not two. This is just a bare supply with no power cord and no load supply cord or connector which I already had. Another P/S which I got on Amazon is rated for 3 amps at 5 volts DC but the voltage drop with the required load was too great to run the two hard drives. It works fine for less voltage-sensitive loads. This P/S is much physically smaller than I expected but it seems to work well for my needs.

I bought this power supply to supplement the 12 volt supply for my 3D printer. it is tied to the pre-switched AC side of the circuit, just after the fused power switch/inlet. The primary purpose of the unit is to power the Raspberry Pi hosting Octoprint. The Pi + night vision camera really suck a lot of power that no combination of USB cable/wall wart could supply. The unit itself is tiny and after some planning, I chose to mount it under the bed. I ended up designing and printing a bracket to side mount it to the V-slot extrusion of the printer frame. The flap over the screw terminals does a decent job of protecting your hands from accidentally getting shocked, although a piece of electrical tape might help if you're still worried. It has an adjustment pot on the side of the terminals that I used to tune it to 5.1 V which the Pi seems happy with. It also has a little green LED indicating it is energized. Being passively cooled, I was worried it might heat up but I can confirm it stays cool to the touch regardless of what the Pi does. Overall, for about $10, I think it finally solves an issue I've been dealing with for ages with OP. It also gives a bit of headroom if I want to add other 5v accessories like a set of LEDs.

I used this to power my Raspberry Pi with several relays. I needed the higher AMP's that this provides!

No issues as of now. Works just fine.

Convenient and cool! Seems to meet power & voltage ratings, though I haven't tested it under load.

Nice power supply.
