The battery holder for the cr2032 coin cell was manufactured incorrectly because it had identical contacts touching the bottom side of the coin cell and no contacts touching the top side which is the plus side.
Fortunately, i could bend the contacts on one end of the battery holder to touch the edge of the coin cell instead of the bottom face and restored its function.
You have to make sure that the plus side, which is the upper face of the coin cell, is the set of contacts that you bend. You can see the plus and minus polarity markings on the white silk screen ink on the circuit board.

Love this little device. real useful for testing cables in the field (av work) and great for getting rid of suspected faulty and charge only cables. build quality could be better usb a 2.0 port and lighting both feel low quality. for such a cheap price this item is must get.

Works pretty good with a variety of cables! you can use a cr2025 or a compatible "button" battery as well if you don't have cr2032. unfortuantely the "vin" isn't a usb jack, but some plastic [+,-] plug, so it's not very useful... :(

Arrived on time and well packaged. thank you so much!!!

It works as it should; I was able to test all the connections with this cable tester except for the lighting connection.

I bought this device (and two other testers), which traveled half the world to reach me, but at the end of this process, the Pocztex courier refused to arrive and deliver the package to the address, instead returning it to the sender (in a phone conversation, the reason given was an incorrect address on the package, making delivery impossible). Fortunately, the purchase was a "Choice" item and Aliexpress acted quickly; I received a refund and bought the testers again, this time from an InPost parcel locker (and now I only order this way). This time the device arrived to me, I assembled it and tested it with my working cables - it's in perfect order and works flawlessly (see photo).
C
Worked to check a variety of usb cables i had collected over the years. item arrived in good time and was easy to assemble and use.
T
A very useful device. When i started testing my cables, i was surprised how many of them are only suitable for charging. The tester clearly shows via leds which pins are connected. All pins are labeled on the tester, and there are also exposed test points in case someone wants to probe them with a multimeter.
I recommend the version with the acrylic cover — it makes a pretty nice enclosure
M
It is necessary to know the pinout of the cables in order to interpret them. Useful for determining whether we can use the cables for different functions.

the box 📦 It arrived slightly damaged but the product was intact.
All that's left is to test it; I hope it works perfectly.

Works
O
It works very easily with a battery, you can control many types of USB cables with this, and also the ones you build yourself, which saves you problems and questions;-) LEDs light up well.
P
Works very well within its capabilities. A suggested enclosure would have been helpful.
G
I still don't understand why I bought this gadget.
Judging by the light indicators, you can distinguish a data cable from a charging-only cable.
E
Arrived with the battery slot contacts not bent into the correct positions, which nearly had me refund the tester. After bending the pins correctly, it now functions as intended
J
Would have been even better w a simple user guide how the leds should light up for different cables - with simple pictures or similar
R
It tests cables very well. I recommend it.
