so I have a Linksys router which I want to power with batteries. so it can be a portable router.
The Original Power supply for the router is rated 12V DC 0.5A MAX.
I've tried powering the router with a 9v alkaline battery and weird things happened. ive expected it to be under powed, by that it won't even turn on or work, but what happened was The * Battery got hot and the* router main chip got really hot.
so my question is why did the Chip and battery get hot, and will it work fine and not get hot if I add two 1.5v batteries and make a total of 12v.
also what are the problems i can face when using batteries, to power an electronic such as this.
