Quick & Easy IPod Charger / Portable DC Accessory Jack





Introduction: Quick & Easy IPod Charger / Portable DC Accessory Jack

This is a S U P E R simple design that will allow you to run many different DC accessories off a simple battery pack.

Step 1: Obtain the Parts

1 ea - DC Accessory Jack
1 ea - Battery Holder (x8 AA)
1ea - 9V Accessory Lead
8 ea - AA Batteries
1 ea - Velcro Cable Wrap
1 ea - Car iPod Charger (optional)

Step 2: Make Your Power Connection

I hard-soldered the 9V accessory plug to the DC accessory jack and used a bit of heat shrink to make it look nice. Once you've made a good connection, the jack and cable shouldn't be very much longer than your battery pack.

Step 3: Put It All Together...

Take the velcro cable wrap and secure the accessory jack to the battery holder... and there you go! Instant portable DC accessory jack.

This jack with my Maxell 12V charger will charge my iPod from dead to fully charged in just under 2 hours. It is also useful for cell phones, pda, PSP, portable DVD player, and most any mp3 player, cd player, or tape player.

    Clever idea. It's one of those things I don't really have a use for, but would keep in my glove box in case the opportunity ever arises where I need a portable 12v DC jack. One idea i just had is to make it work with rechargeable AA batteries and make it so you can run a cable with a diode from your car DC jack to the battery DC jack. Then when the batteries are dead you can recharge it in your car.

    the current supplied by your car battery will fry your battery!


    I was under the impression that devices only draw as much current as they need. But you wouldn't want to run 12v straight through the battery. You would drop it to 2 or 3volts and charge it more slowly.

    well, do this, drain a ni-cad batttery, so the voltage Stays 0 now take an ohm meter and measure the resistance, you will find it relatively low you car battery can supply 1000A, no problem, your batteries shouldn't be charged with more then 500Ma/h

    I bought a car power converter so the ciggeret lighters are like the power outlets in your house. do you think you could step it up a bit and and have a portible house outlet in your back pack or somtin?

    Won't work, not enough power

    This is cool, but a bit unnecessary... Most 12 volt charges have some sort of step down inside them... So you a re wasting a lot of energy here. You are going from high to low when you can simply go from low to low voltage. Cool idea though! If I saw this in stores, I would probably buy it.
