Review: Works great, has an intuitive set of screens and a very clear display - This is an excellent tool to have when you are working with USB-C powered Microcontrollers. I am programming ESP-32 CYD LCD displays which have a battery charging chip in them. This tool lets me see the charge rate of the battery by subtracting the normal operating current from the current the unit reads while the battery is also connected and the USB-C is connected. Very handy. The screen is very clear and readable. There are a number of screens that show various values but for me, the current is the most important.
Review: Good price & functions perfectly! - Nifty & handy little device, works both to insure cables & power bricks & various USB & USB3 are functioning correctly, with all the iPhones, computers & tablets & miscellaneous cables troubleshooting broken devises & cables sure is simple now

### ⭐⭐⭐⭐ Works great
*by D***E on December 14, 2023*

This was delivered on time. I misunderstood a few things in my testing and the manufacturer was quick to respond to my questions. I believe that I tested every J7-c configuration. While I cannot vouch for the accuracy - it did what I needed - I can state that everything worked. There are some limitations in the device, but more on that below. Most of the limitations seem to be due to destination plug standards. USB to J7-c to USB to lightning Input - I tested this with both a powerpack and plugged into the wall charger Output - to a magnetic charger for an Apple Watch Result - perfect USB to J7-c to Type-C to lightning Input - I tested this with both a powerpack and plugged into the wall charger Output - to a iPad Result - perfect Type-C to J7-c to USB to Apple magnetic charger Input - I tested this plugged into the wall charger Output - to a magnetic charger for an Apple Watch Result - no output, however, the manufacturer told me of this limitation: "Apple devices don't support charging like this because Apple’s charging system is strict, it with a charging identification chip. If you use this usb tester to test Apple devices, it only supports Type C-Type C-lightning or USB-USB-lightning or USB-Type C-lightning." Type-C to J7-c to USB to mini Input - I tested this plugged into the wall charger Output - to a Garmin Result - same as last test, probably due to same "standards" limitation Type-C to J7-c to USB to micro Input - I tested this plugged into the wall charger Output - to a powerpack Result - same as last test, probably due to same "standards" limitation Type-C to J7-c to Type-C Input - I tested this plugged into the wall charger Output - to a iPad Result - perfect MicroUSB to J7-c to USB to USB micro to a powerpack Input - I tested this plugged into the wall charger Output - to a powerpack Results - Success MicroUSB to J7-c to USB to Type-C to a magnetic charger for an Apple Watch Input - I tested this plugged into the wall charger Output - to a magnetic charger for an Apple Watch Results - Success MicroUSB to J7-c to USB to USB mini to a Garmin Input - I tested this plugged into the wall charger Output - to a Garmin Results - Success MicroUSB to J7-c to USB to USB mini to a magnetic charger for an Apple Watch Input - I tested this plugged into the wall charger Output - to a Garmin Results - J7-c showed input power level, but no output power created In summary, a) the J7-c with USB input worked great for all output types I tested b) the J7-c with Type-C input worked fine when the output was Type-C c) the J7-c with MicroUSB input d) J7-c use with Apple Lightning can be problematic This fits my needs now that I know the limitations and I recommend this to other users.
