Very good powerbank - I tested for 2 weeks. QC2.0, QC3.0 control on USB A output is working properly, PD USB-C control 5V (5.3V), 9V (9.4V), 12V (12.5V), 15V (15.5V), 20V (20.4V) without load switches correctly. Load at the output 5.2 - 19.7V6.11A = 120.37W. In my opinion, the efficiency of the device is too low - I used 20 NCR18650B 3.7v 3100mAh batteries soldered with 8x0.15mm nickel-plated tape. The measurement table is attached. Very good contact with the seller, he answered several questions - thank you very much :) I recommend the powerbank and the seller.
This product is for mid and high level people with some electric knowledge. The connection must be clearly understandable in your head. Good soldering skills and quality cables needed make connection. It can charge the 65W lenovo carbon laptop easily. I used 2500Mah batteries. The product case really quick. I had to wait for welding machine to try it. The inside space can be exended with some sandpapering but becarefull to buy correct sized batteries. I suggest you test all batteries with discharge test to make a quality long lasting power bank. The connections from The power board to LCD screen connection is very bad. In several tests the silicone was teared and the LCD button cable has been split. I had to solder it againand used silicone fix it but the led panel is not working with full light power. Thats why I gave 4. As I observed I could get the batteries charged up to 4.1 volts with 12V 2A adapter. If there is a better adapter for it please advice.
