Waveshare 5V/4A Power Supply for Jetson Nano and Other Electronics

I purchased this pulg from the load test review it was 5.24 volts and has worked find on a expensive dj Controller

Works as expected so there's no real problem with it

Waveshare 5V/4A Power Supply for Jetson Nano and Other Electronics*Appears to be a good PSU.Did a load test, using an 'Atorch AD18' load meter (the standard UD18 meter + load)The results were as follows:0A / 0W (no load) 5.23v1A / 5.19W 5.18V2A / 10.28W 5.13V3A / 15.28W 5.07V4A / 20.37W 5.02V4.5A / 22.50W 4.99VThe 4A load was run for 30 mins.The 4.5A load was run for 25 mins.I didn't run it at the maximum 5A load because the load could only go up to 4.9V, so I chose 4.5A as the maximum.As can be seen from the figures, there is little voltage drop between 0 and 4.5A. This is good. Even at 4,5A load, the voltage was still just about 5v.Generally, it is not recommended to run a PSU at its maximum stated Amps. Poor (and usually extra cheap) PSUs will often struggle if the load is at maximum, possibly resulting in a large voltage drop, restricted power, poor performance, or even dying.There should be no problems with this PSU. It ran flawlessly at the 4.5A load. Although this was just on a load test, I see no reason why it shouldn't work OK with any suitable 5v equipment.The PSU ran hot on the 4.5A load, but that was expected due to the high load and the smallness of the PSU. Measuring with a point and measure thermometer on the top of the case, the temperature was approximately 65C nearest the cable end, reducing to around 38C at the bottom end.

Just what I needed! It's a plug so there's not much you can say about it other than it's great quality and works perfectly, what more could you ask for?!
