It was purchased for about 14 euros for simultaneous charging with a total cumulative power of 40W and above for two Xiaomi Poco and iPhone mobiles or, if applicable, two Powerbanks, one Xiaomi 10000 mAh with 18 Watts and Baseus 20000 mAh with 20 Watts.
In combination with high-quality Baseus cables, one from USB 2.0 Type C to USB Type 2.0 C 3A and the other from USB 2.0 Type A to USB 2.0 Type C, it delivers all its power simultaneously without interruptions during simultaneous charging, and just as fast as the genuine Xiaomi and Apple chargers.
Initially tested on two Xiaomi mobiles, both charged quickly with the double lightning symbol. The same goes for a Xiaomi mobile and a Baseus 20000 mAh Powerbank, both charging at maximum speed with the double lightning symbol, and the Powerbank with the red lightning symbol.

It supports 2 charging ports and 2 common charging protocols together.
From the USB Type C port, it supports the Power Delivery 3.0 protocol, which is one of the most common and supported protocols in almost all mobile phone, powerbank, tablet, and laptop manufacturers' fast charging standards. This means it can charge iPhone 8 and above with a Type C to Lightning cable, Xiaomi, Samsung, Huawei, OnePlus mobiles, iPhone 15, Powerbanks, tablets, laptops, etc. with a USB Type C port, with a power of 25 Watts and variable voltages and currents ranging from 3.3V to 12V.

From the classic USB Type A port, which is green in color, it has a power of up to 18 Watts and supports the equally famous Qualcomm Quick Charge 3.0 protocol, which is supported by older and current mobiles with Snapdragon/Samsung and Xiaomi processors, as well as a multitude of devices and Powerbanks, EXCEPT for devices that support ONLY Power Delivery. This means that if you have an iPhone, a laptop with Type C, or even a 65 Watt charger, if it has an output of the classic USB Type A to Type C, it will not provide all the Watts but only from 2.5 to 5 Watts. Power Delivery requires a Type C to Type C or Type C to Lightning cable for iPhone 14 and older to work at maximum capacity. Qualcomm Quick Charge 3.0, on the other hand, provides variable voltages and currents of 5V, 9V, and 12V, and the corresponding currents of up to 18 Watts from the classic USB Type A.

It appears to be of high quality at first glance, with embossed certifications on it. Satisfied with the purchase, it is really worth it for about 14 euros, as it is like having two fast chargers in one. It gets quite warm at full load (43W) of simultaneous charging (iPhone Type C 25W + Baseus Powerbank Type A 18W), but it consistently and correctly delivers the charges. You can charge two mobiles or a mobile and a powerbank simultaneously and quickly without any issues, which is perfect for vacations or outings.
