USAMS US-CD92 PD power bank

According to the characteristics, it should be 5V / 3A. Tests for the load of the USB-A port of the bank passed. Charging the phone for a long time did not work, but we managed to get the power bank to charge through the Type-C port Moreover, this is the first generation of USAMS magnetic wires.
At the moment of switching the voltage on the UM25C tester, it determined the protocol as WC3.0, but in the photographs ( when 9 and 12V were selected) the protocol was listed as "unknown". Photographs of the current strength through the magnetic and two simple wires.
Therefore, in my case, it is better to change not the IP5328P chip at first, but the Type-C connector itself. As noted in the comments, https://jiji.co.tz/cars/toyota-rav4-2015 the reason for the port not working may be precisely in the chip, but with additional research and the banal pressing of a prominent loose contact in the port, I managed to force it to charge/s through the USB-C port, but the joy was not long.
Exactly in the same position as in the photo above: we used the TIEGEM Type-C adapter (male) to micro-USB (mother) and only in the position with the inscription down (another adapter, in which instead of micro-USB USB did not charge). We loaded 3A and the bank withstood both 9V / 2.0A and 12V / 1.5A: If you connect to testers at both ends of this network (to track readings), then charging did not go on. The shorter the wire, the greater the current. On magnets, the current is always less.
And the third wire, also from USAMS, 0.25 m, carried current from the power bank to the phone with the highest rate. The power bank was charging.

The magnetic wire (1.2 m) showed the smallest current strength of the three cables. Through it, the current strength increased. Replacing the port, I found out, will cost from 500 to 1000 rubles, but with such a price, the repair of the port does not shine 🙂 The power bank itself practically costs like the upper price of the Type-C replacement interval. These were my first wires from AliExpress. When I had testers and a load, I began to take a more reasonable approach to checking goods from AliExpress. After a long communication with the store, I was lucky to get a power bank from them at a big discount. Perhaps he broke it himself or sent a defective product.
The tester from RD determined the supported current at 2.4A.
The second wire is a 0.3m wire from Tiegem. I have used USAMS wires for a long time.
