Agreed.Aside from the "odd" application such as **cough** flashlights? Nope. Mention 510 connector and it's pretty much a given you're talking about vaping equipment as that's the common use for that designation.
I am not sure but,as far as i can tell a 510 connector has only one use.
(modding it for a flashlight doesn't count.)
When one google's 510 connector the results show a ton of sources from vape supply vendors.
When one google's electronic connectors and then checks companies like Digi-key,Mouser, or ,
Allied,etc, one can not find such a connector in general use. Molex makes a connector with 510
in the part number. No picture is available. I don't think it's what one would think of as a 510
connector.
I had never heard the term 510 connector prior to vaping. Since then I have never heard the
term 510 connector used other than to refer to a connector used in vaping devices. I believe
@ENAUD is on the right track. If the parts are allowed to maintain their status as tobacco
products one will have to fabricate there own hardware in a worse case scenario. On the bright
side there a probably so many of these sitting in bins of vaper stores everywhere availability
will be more of a long term issue. The only reason I am mentioning this is seems that common
wisdom in the vaping community says they (the powers that be),can't regulate a connector.
Well it's a proprietor connector not in general use. This could be one of the reasons the FDA
wants their hands on the hardware.
