I would recommend that the product arrived early
Very handy. These will test USB-C to USB-C, USB-C to Lightning, USB-C to USB-micro, USB-A to USB-C, USB-A to Lightning and USB-A to USB-micro. It requires a USB-A to USB-C cable and basic 5 watt USB-A power supply (not included). It tests Data, Data-, VCC, Ground, and C connections. Does not test the extra conductors on Lightning or high speed USB-C cables. Not only does it test conductivity, but I have notice some cables where the VCC LED was weaker indicating a poor quality cable (this could slow charging). So all around a handy device. I have bought 14 so far with only one failure (Banggood replaced the bad one). Thanks for the replacement!
I have been giving these as gifts. Very handy to be able to tell which cables are power only (good for use on public charges to eliminate security concerns). I may see about mounting these in boxes along with a battery.
Rendben, időben megérkezett. Egyelőre megfelelően működik.
awesome product arrive soon and working great!
This product is arrived in good condition and quickly. The quality is good.
Excellent I arrived the day indicated, very practical works to perfection.
Very useful tool to verify continuity of USB cables and also to identify in they are for charging only or also supports data.
The shipment has arrived, the system is working...
