Good Morning Everyone!
Hopefully someone will be able to help, We're looking to try and get the garage keyfobs (3 simple button fob) that open and close the Garage door but have it as a perm item powered by the cigarette lighter. It's hard to explain exactly so i've included below a link to an item very similar (sadly it wont work with our Mhz gagage door)
https://www.ebay.co.uk/i/1822862577...=9045311&device=c&campaignid=857333952&crdt=0
Would there be a way to take the internals of a current keyfob and convert it to be powered via the cigarette lighter? I was possibly thinking down the route of an USB end to the battery sections of the internals of the current normal fob however i'm worried about amp-age etc (the fob runs off on a A27 battery) which i believe only about 25 mamp but 12V - A USB would be 5V and 500mamp, Not enough voltage to power but enough amps to most like damage the circuits.
Any ideas on how i can convert this keyfob to be powered of either USB (can then just connect to a USB lighter socket bit) or any other ways?
