I'm new to circuit board engineering, and I would like to make an external battery pack for my consumer electronics.
I would like to have a battery pack that runs on AA's that I can use to charge multiple devices(mp3 player,cell phone, portable DVD player, etc..).
I can use both a dc plug(the kind that plugs into a car) or an ac plug. (would prefer that it used ac if possible).
I would seperately charge the AA's.
Can I just hook up a dc outlet directly to the batteries, because the dc plugs have transformers built in, or do I need to do more?
Are there any links to sites that would help or can you guys tell me what to do?
Thanks.
