KOOBOOK 1Set CH341A 24 25 Series EEPROM Flash BIOS USB Programmer+SOIC8 SOP8 Test Clip+SPI Flash 1.8V Adapter+SOP8 SOIC8 to DIP8 Adapter Socket Converter

I'm entirely convinced that people have never actually tested this device while in use then state you should convert it to 3.3v. While flashing it is the correct 3.3v but when it's not it will show what is perceived to be "incorrect" voltages. this is the intended function of the device and works flawlessly. Yes the device the device doesn't come with instructions or software but if you're buying one of these you should already have enough knowledge where this would never be an issue. Great product that does exactly what it needs to do.

I didn't bother trying the programmer. The accessories - the clip, adapters, and sockets - work great with my Batronix programmer, though.

I was confused at first as it's my first time using it, but with a quick YouTube video I was able to figure it out and crossflash my 7900XTX to a new higher power VBIOS!

It worked great to backup/restore BIOS on 1.8v winbond 25q64fw for a Lenovo Ideapad 330s-15arr. Laptop would not post, black screen, fans running, LED light on. Used the CH341 to read/backup current corrupt state of BIOS and then using the backup to find and copy important information. Lastly inserted the copied information into clean BIOS before writing back to chip. I had to reposition the clip a few times as it was not seated properly and my application would not detect the chip but once the connection was established it worked fine.

Zero clue what it does or what the point of it is, but my son asked for and is thrilled and said it's allowing him to do what is needed between his two laptops...
