Topic: jb3 external power II...

[Krispy D]

^^^points 1) and 3) are interconnected.

If you run external power with internalls that are not fully charged the unit will atomatically charge them.  If you run external power with fully charged internalls you should have nothing to worry about.  as well as the confidence that if your externalls run out the jb3 will continue to record powered by the internalls. 

NEVER run externall power with undercharged internalls!

Thanks for the info, and +T to both of you.

I run my NJB3 with internal battery in and charged.

I can get over 12hrs from a 9V, 5400mAh battery (*), running just the NJB3.

(*) 7805 regulator running directly to the internal cells.  Maybe risking a meltdown ala uTrack, but that's what I do.  If I run from the 9V output, the battery cuts out sometimes, probably due to large current draw attempting to charge the internal battery.

Thanks for all of the tips!

Other easier power supplies include a lot of the external batteries for the PSP (PlayStation Portable) as it's also 5V.  I have 3 battery packs, 2 Lion that work great and the one I reeeeeeally wanted to work doesn't.  It's a battery pack that takes 4 AA batteries and is supposed to power the PSP with 5V, but for some reason it doesn't work at all with my CJB3.  I don't have a PSP to figure out if it's a faulty unit or not.  Picked it up in Florida on vacation so I haven't tried to return or exchange it. 

The Lion ones will power the CJB playing about 8 hours, they seem to get between 4 and 6 hours of recording time.  Both that I have are color coded for green (full charge), yellow (half charge), and red (about to die) so they are really handy for recording and if you slap in a battery while in the red, it will continue recording without issue.

This one is my favorite and has a built in flashlight that is super handy in the field!

Does that battery you found on ebay come with a charger or do can you use the wall charger that comes with the JB3? Anyone have any luck with this?

Came to about $26 US with shipping.  Unlike the other AA Battery pack I have, this has the 20cm long plug...looking at the one I have that doesn't work, it's only about 12cm.  It will probably work on a PSP like stated, but didn't work for the CJB3. 

While the Lion batteries are cheaper, I think something like this is a great fallback for festivals where charging it isn't an option...you can buy a bunch of AA batteries for a decent price and have unlimited power with this adapter.

So all of you with a good powering solution...

Wanna Buy an Oade WMod+ UA5 and JB3...

I just ordered the 660! 

[rowjimmy]

hey rowjimmy

this thing still working for you?

I just picked up this : http://www.bixnet.com/hicamiexbapa.html

Has pretty much everything that the Digital concepts product has plus more power (4400mAh @ 5v).

The thing that sold me over the Digital Concepts product is that it was actually instock (i looked everywhere for the other) and i could get it before leaving for vegas.

Sorry I'm so late in replying to this but... Lemmee tell you. this battery still smokes. It ran like a champ at vegoose. I never had to use my two internals (which I had on hand and charged for back-up.) I wouldn't even think of running the jb3 on the internals except as a backup to this battery. Its easy and has terrific capacity. It also powers my m-audio audiophile firewire... (seperately, of course.)
I may buy a second one for the pre that i'm eyeballing...

Thats a real good Idea IMO

ps.
Oysterhead I’m kinda thinking your PSP Batt pack does not work because that it’s not enough mAh.  I've tried a few different Car adaptors for the PSP and the first of 3 different ones have worked.

This is a much better way to power your jb3 $29.99 from Fred Myer comes with the ends to fit almost everything has a 5volt output setting and is rechargable from the wall and from your car.
4000mah lithium-ion with a little meter like the wallyworld battery only smaller.

I'm a little slow so please be bare with me. Can I just plug this in to the JB3, or do I need to sift through ends to find the right one. And what would happen if I chose wrong.

Yes, you have to choose the proper tip and make sure that the polarity is correct.  If you choose the wrong tip it simply will not fit into the jack on the JB3.  If you polarity is wrong it will not power the unit.  You will know if you have it right because as soon as you plug it in the unit boots automagically.  I use one of the PP99 dealios and it rocks. 

I picked up one of these (PP99) and I'm pretty sure I am using the right tip, but its still not powering up... You can't really reverse the polarity on these, right?

hells yeah you can reverse the polarity, thats why there is a POSITIVE (+) end and a NEGATIVE (-) end RESPECTIVELY. You better hope you didnt fry anything Nick

[Jeebas]

Well how can you reverse the polarity then - I thought it was merely done by changing the way the tip was placed onto the cable...? And thats kinda an impossibility with these because of the truncated circle shape the connectors are in

[Jeebas]

Also noted that my JB3's DC IN works fine with an AC adapter plugged in... Maybe its just the cable, I know it needs tip negative but there is no indication of how the cable-adapters are that come with it. And I really have no idea about this stuff.. Any  help would be awesome...

[Jimna]

try a ISO:jb3 power cable in the YS.  see what pops up, lots of folks have old jb3 stuff not being used anymore, might find a cheep solution.

Well I mean I just dropped $30 on this, and Shane has the same exact thing, so it SHOULD work with what it came with. 

Thanks for the advice though
