So I purchased a clone no name plug in rda. I didn't realize that it didn't come with a regular 510 pin and that it only came with a squonk pin. So I'm wondering like how interchangeable are 510 pins and squonk pins if it didn't come with the device is it likely that I'll be able to find a 510 that fits or is it sort of like I'm out of luck because nothing came with the device?
