Stupid question: How can I use this nice device with USB-A ports (both in and out)? Can I use adapters (USB-A to USB-C, microUSB to USB-C) or is it not recommended to use adapters? Will adapters have any influence on the results measured by this device? Thanks for your feedback!
Using any kind of cables/adapters can certainly increase resistance and impact readings. If you want to avoid having to use those, for USB-A, look at the UM25C:
RD Technology also sell adjustable DC power supplies but you need buy case in their store and build up by yourself, It is 328 festival so you can buy that at a inexpensive price,just have a look at RD technology or other stores, buy the one fits you. :sunglasses:
you can use adapters but it will influence the accuracy of the result because of its resistance, the Micro-USB port of TC66C is used for independently charging, so this device is designed for Type-c port. hope it helps you :student:
they give me a product , then I test it and write an article so that I can get this beta TC66C for free, :laughing: you can just have a look at their eshop,they have their own factory. https://rdtech.aliexpress.com/store/923042
“For CC drop-down:PD stipulate that type-c interface has no output by default. When there is a drop down on the CC line (pin in the Type-c interface), PD charger thinks that the load is connected and then starts the 5V output. Therefore, it is normal for the tester to plug directly into the PD charger and not light. if CC drop down is enabled in the setting of TC66, when you plug TC66, it will automatically brighten the screen after it is set as enabled, but it may affect the normal charging process. If protocol detection and trigger are to be carried out, CC drop down must be enabled, and the back end shall not be connected with any load. If it is set to be off, the charging of PD charger will not brighten the screen, and the charging process will not be affected. Please first plug the tester into the charger and then insert the load.”
