ATORCH DL24 / DL24P Power Delivery Power Supply Testing

This is the sixth video in a series on the ATORCH DL24 / DL24P electronic load and capacity tester. The DL24 can be used to test power supplies. In this instalment I test a pair of power delivery (PD) power supplies to show how to test them (trigger required), what happens when we go past their designed operating parameters and the difference between a high quality name brand PSU and a budget PSU.
This is the last planned video for the DL24 / DL24P, however, if there is some other type of testing you would like to see if used for please write into the comments below.

I have 3 variations of these testers: DL24, DL24P and DL24MP (compact, with the display on top of the fan). All 3 exhibit the same problem with the USB C connector on the little adapter board. The tester detects the source voltage (and the little blue LED on the board lights up) only in one direction of the USB C connector. If I flip the connector it no longer detects the voltage. Same thing happens if I turn the cable around, with the other end plugged into the adapter board. If I flip the connector plugged into the source there is no problem.
Since this happens with all 3 adapter boards and several cables, I believe they did not wire the USB C connector to the little board fully.

Hello sir can you use this tester to discharge a single cell lifepo4 3.2v 280Ah? Thank you

It kind of depends. The typical discharge current for this sort of cell is 140A (448 Watts). The DL24 has a maximum current setting of 30A (96 Watts). If you wanted to do a capacity test at the 30A level that would work as 96 Watts is well within the power handling capacity of the unit. However, if you wanted to do a test at the typical 140A level you would not be able to.
