I'm confused about what I'm supposed to use/do so that I can power the webplayer in my car. Can someone please tell me the least expensive way or the simplest way of doing it? Am I correct in guessing i'd be needing to find a power supply of some sort that has 5VAC @ 5A with and 50+ watts? I'm not exactly eletrically-savvy, but I do know people who are, if I do NEED to go that route. So please help me out. :\
Is the DC-DC adapter the only thing I would need? Because I am about to get my hands on an already modded webplayer, but it doesn't come with a power adapter of any kind. So I was trying to find out the most direct way of hooking it up to the car. I tried looking around the net for a car power adapter (the ones that plug right into the cigarette lighter), but none of them provide 5v/5a/25w. What do you guys think?
The cheapers and best way is building your own step-down converter
The only expensive part you need to do this is a 5A Step-Down, PWM, Switch-Mode DC-DC Regulators
