Hello and thanks for your time reading my post.
I've my router connected with its adapter and a battery for backup. Details: The adapter output 15V and 0.4A The battery output 12V and 12A The router needs: 9V and 0.6A (I've a regulater to minimize 12V to 9V to fit router needs).
Now, if I connect the router's adapter with battery then to the router, the router will take power from where? The adapter or the battery?
Thanks.
