high voltages on usb to TTY UART?

Hi, Any1 have experience with this usb to TTL 6 pin converters? I just want to know if I have a dodgy one that I bought from Ali or normal behaviour.

Doesnt seem right. I have it plugged to a powerbank, following voltages read from pinout, without any jumper link.

5v = 5.3 Vcc = 3.9v 3.3 = 3.2v Tx RX = 3.9v

If I use jumper link from 5v to VCC, then tx RX = 5.3v, if I jumper link VCC and 3.3, RX and tx = 3.9v.

Thanks for reading

(Solved) How to save URL to homescreen? It doesn't keep the link! Grrr

Hi all, so as per title, when I use browser app to make a pwa or 'add to homescreen' it works, but then opens the home page not the actual link I had created. From memory there was a hack where you would put your phone offline, airplane mode I think' and then it would save the link. But doesn't work anymore. Any1 have any solutions? Tx
