Nice! which one did you get?The USB load tester came in today, and it’s pretty sweet. I hooked it to the back of my USB meter, cranked it down, and hooked the USB meter into a spare 1A USB wall wart. At first I thought it was a 300mA wall wart, and I was impressed when it didn’t skip a beat, maintaining a little over 5V steadily without issue. Until I hit right around 1A, and then it fell on its face, dropping voltage off a cliff. I looked at the label again and realized I had glanced at the input amperage rather than the output. It provided up to 1A faithfully but no more.
I’m looking forward to getting those hardwire 12V USB power supplies in to see how far I can take them. In theory the dummy load should run out of additional headroom about the same time the power supplies do. If it keeps up all the way to 3A I’ll be duly impressed. If it actually keeps that up for years, I’ll be delighted
