Connector for standard 405 nm laser plug?

[mrsinbad]

Hi all. Kinda a newb to lasers and I was looking for some info for my 5o mw 405 nm UV laser pointer. Sorry I can’t post a pic as the file size is too large to upload. Anyway, the plug looks like it’s a std male plug with a center pin about 3mm diam (+) and an outer perimeter tube about 8mm (-). Wut I’m looking for is an adapter with female plug on one end and a make USB type A to plug into my power bank acting as my power supply.

I hope this is an easy question for u folks, but I dunno what to call these adapters and where to look to buy one. Can u help? Got a pic?

Thanks so much in advance.

Oh, I thought of another way of describing the plug…. It looks more like an RCA plug but with a much shorter center pin. Hope that helps.

Google IrfanView App for manipulating image sizes, etc. It's a free program, it works very well, and I have used it for close to 20 years.
