KR808D-1 Auto Battery

When it says it's much less sensitive, is that when your using it or not? My 510 auto batteries don't activate when I use them unless I take a hard drag, will these be harder or easier? Thanks.

Edit: I got a Vapor King with an auto battery and it's much better than my 510 ones. Is this the same?

should be the same exact thing as the vaporking
