HKJ, do you have any plans to test some USB C devices?
My new laptop charges by USB C which is great, obviously it came with a wall wart charger but I’d be interested in getting a few others.
The USB C also allows me to power the laptop by my power banks, however at present I only have old USB outputs so it is a very slow charge. Some USB C power banks would be very interesting.
USB-C can be very complex. The problem is when communication is required, I do not have anything to do that yet.
I have made test equipment to handle more simple USB-C devices and are working on a power bank with USB-C at the moment.
There’s a somewhat recent USB tester on the market, model J7-t. It comes in two flavors, with the markings “USB safety (or security) tester” and “QC2.0/3.0/MTK-PE Trigger”. The safety tester supports QC voltage ranges and the “trigger” variant claims to support putting the power supply in QC mode (and many sellers warn against connecting a normal device when QC is triggered). It’d be nice if you could test either of them since they’re a cheap alternative to the XYZ Studio testers.
I think you are talking about the one I have. Mine is marked as Security tester…
I can not do a review as HKJ, because I dont have the knowledgements and the equipment to do reviews and tests as HKJ,… but… I did 2 videos showing it.
The first “problem” with it is that the screen is a bit difficult to read specially in high light conditions… but… about current and voltage readings it seems ok
I asked Franky if he’s ever going to sell these, but he said that the ones with batteries are almost impossible because of Li-Ion restrictions. And the empty housings are probably a bit too difficult for most people, because the latest versions require soldering or spot welding to form the 4P/8P battery packs. Earlier ones were also available with spring terminals.
