18v drill battery to 5v regulator??
Hi I have been doing a bit of research but am still a little unsure,
I am trying to charge an iPhone from a dewalt drill battery,
What I have so far is that the iPhone is a 5v 1000ma supply
And the dewalt battery is 18v lithium ion
Can I use a 7805 regulator or will I have to use a 7812 regulator first?
Also what heat sinks etc would I need
Thanks for any help
Sorry not up on the electronics ! Ha
