Arrived in an antistatic bag. I didn't notice overheating when using it for long periods of time. In general, the soldering on the PCB is excellent. I powered the module with a laboratory power supply to run tests on it. The connecnors are solid and well made. Works fine from 12V or 30V input and running cold under max loads. There is a convenient connector 5.5 x 2.5 for powering the module. It fast charges the smart phones and any other USB device I connected. According to my protocol detector tests the supported output protocols for the two USB-A ports are: Apple 5V/2.4A, Samsung 5V/2A, BC1.2 DCP 5V/1.5A, Vivo Dual Flash 12V, Qualcomm QC2.0/3.0 12V, Samsung AFC 9V and Huawei FCP 9V. Both ports support a total of 3A 11.8V output. In QC3.0 I measured a max output of 1.5A 11.8V for each one of the ports. Only drawback is that the edges of the USB connectors are at the same level with the PCB which makes difficult the USB connectors to stick out seperately from a casing.
