i was tossing around the idea of getting a small 12v system JUST for the jb3 in long hauls

so all id need to do is crimp that cable and BAM, no voltage regulators or anything, just splice car cable and crimp???

thanks

Radio Shack Adaptaplug cords.  Get a MALE TO MALE and a FEMALE TO FEMALE.  Cut 'em in HALF.  Snip the cig lighter plug OFF the Creative Car Adapter and crimp/shrinkwrap (or e-tape) a FEMALE END on it.  Crimp & shrink/tape a MALE end onto what's left on the Car Adapter.  Crimp & shrink/tape a FEMALE end onto whatever you end up connecting to your battery (I just added it into the XLR/4 end of the cable from my EC-90 to my D-10).

Now you have an INTERCHANGEABLE SYSTEM, and you can use the "Adapta-Plugs" to power OTHER 12V devices off your battery if you want.  But BE CAREFUL that you match the TIP to the CORRECT POLARITY (+) - in the case the the JB3 Car Adapter.  ALSO BE ADVISED that the PLUS WIRE on the JB3 Car Adapter is the one that DOESN'T HAVE THE SILVER WRITING on it.

and get a couple of the RC Battery type plugs.  They come with crimps already on them, and are IDIOT PROOF as long as you WIRE THEM CORRECTLY in the first place...

I used to do this, but I found the RS adaptaplugs so damn finicky - sometimes would plug in securely, often times wouldn't - I bailed and just started hacking my wallwart cables.

Don't wanna be a contrarian here Bri,

There are a number of different connectors that are REAL CLOSE (same outside diameter, different inside diameter, etc.).  I've made that error a couple of times (and PAID for it).  Sony (on thier laptops) are NOTORIOUS for making non-standard size plugs - real hard to find a match that feels perfect.

This (like whether you like the sound of your mikes/preamp/speakers/DIN/NOS.XY/ETC/ETC) - really comes down to personal preference.

I enjoy the versatility of the adaptaplugs and they work for me, others like the snug, secure feeling of slaughtering an innocent wallwart...

They ALL work - do what you feel comfortable with...

Good points, Rick.

If that ^^^ was the case all the time, I wouldn't have bailed on the flexibility of the adaptaplugs.  Besides...I like hearing the wallwart cables scream when I slice 'em!!

Rick, just so Im sure before I do this, if you didnt want the car adaptor on there, you could just hack it off an solder a 4 pin on there and you'd be ready to go for a 12vt sla??? I was just gonna keep my d8 for bonnaroo and sell it after, but if this works I might sell the d8 soon and just take the jb3 to bonnaroo.

Maybe a little late...it was me who played with 4 NiMh cells.  It does work but Brian's memory is correct - when the 4 batteries are fully charged the voltage is just a little too much for the JB3 and it won't power up.  I now just run a halogen bulb for about 30 seconds on the battery pack and it drains enough to work after that.

I've done the 4 x NiMh (using 4/3 A size cells - 3000mAh), a 9.6 NiMh pack regulated to 5V, 9.6 NiMh pack with a car adapter at 4.5V and 12V SLA regulated to 5V.  They all work.  But really, I'd just go with a 2nd Creative battery if I had to do it again.

You don't necessarily have to go for the Creative car kit - any adapter will do if it has a 4.5 or 5 volt setting.   I use one that's switchable from 3 to 12 volts in 1.5v increments and it was  $10 or so.  Save a few bucks!
