Powering GH2

Alfi666

Yes, I have the same battery holder now ;) ... I managed to put the DC-DC converter to DC coupler... so now I just directly connect the Sony battery.

I got the step up - down converter module. Amazing DC2.8V-32V input very stable output. Waiting for some more parts than will put a video tutorial.

Tested, this step up down converter works OK but it gets hot ... even on low consumption ...

@feha: I have the battery holder from ebay.. but now I'm already using one which is meant for liliput monitor... it has a locking pin, so battery is safely held and have some mounting options too.

@feha @ptchaw seems content with them. I have yet to run a shoot on them. But they took 2 weeks from China to Germany and arrived fully loaded.

feha

@JackBayer, thank you, that is the fastest (chipest) solution. Just wonder about the quality of the cells, do they hold ?

@feha

I have tried it and so did @ptchaw

And just a few posts up I have posted the link to an ebay store with the correct adapter plug.

feha

@Alfi666 where did you got that box for NP battery, from charger ? Link ?

@PixCanFly

Those Chineese copies have not same diameter as the original DC-coupler ...

feha

Have anyone tried this kind of battery ? http://www.ebay.ie/itm/Portable-12V-9V-5V-Li-ion-Rechargeable-Battery-Pack-Cam-/260908805712

I think 9V would be OK for DC coupler ?

@JackBayer Thanks for the help.

So the 3rd party DC coupler take 1.7mm (inner diameter) and 4.75mm (outer diameter) plug like the original? I'm thinking of connecting the 3rd party DC Coupler with the Switronix cable which is 1.7mm (inner diameter) and 4.75mm (outer diameter)

The Switronix GH2 cable

Here´s the correct plug adapter to use with the DC coupler and the 5V 9V 12V battery: http://www.ebay.de/itm/230489661142?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

It´s a thight fit and works perfectly. I am still looking for the right adapter to connect the H4n also.

Is Panasonic killing the DMW-DCC8 coupler? It's insane that everywhere has no stock for the longest time. Are they forcing us to use their over-priced battery?

Anyway, anyone knows whether this 3rd party coupler uses the same plug like the original, as in 1.7mm (inner diameter) and 4.75mm (outer diameter).

I have ordered this one: http://www.ebay.com/itm/150657732239 DC/DC Converter Regulator Step up & Step down 2 in 1 This allows any input to proper adjustable output, will test it when i get it ... Below is image of DC coupler polarity ... sorry for blurry image ...

Just to x-post the info, 3rd party DECODED 1600mah batteries have begun to pop up on the web. They seem to be sold out now, but they'll probably pop back up soon.

feha

@PixCanFly , yes.

PixCanFly

Just to confirm, the outer sleeve of the coupler plug is negative and the tip is positive right?

feha

OK, i have verified the DC-Coupler connector (jack), there is nothing "oposite" at least the original one. The male jack, pin is + (positive), the DC coupler has not any regulator or protection whatsoever, it will just pass any input voltage so be careful.

@redpaw - thanks!

feha

@redpaw , thank you, that helps a lot ...

I will be using this Sony battery plate ... I need some male connector information same from the jack of DC coupler and to the cable jack into battery plate ... between i would put a DC up converter without cutting cables ...

redpaw

got mine from the same seller that @feha. and yes, i'm pretty sure there was something wrong with the polarity ;) the easiest way (what we did) was to use multimeter - before putting in the coupler into the camera compare the polarity with the battery's output - that way you can be sure

feha

@PixCanFly

i'm still waiting for some components, DC step up converter ... will be using sony batteries NP970 7.2 V. Will post a tutorial when ready ... As for polarity, would like to ask if someone owns a AC Adaptor DMW-AC8, if possible check with voltmeter ?! on the jack ...

PixCanFly

@feha what did you use for external power? btw, how should one check the polarity is correct for the coupler? I heard the Panasonic coupler has reverse polarity or something.

feha

Hmm, here i bought mine, genuine: http://www.ebay.ie/itm/190613633995 I'm not sure if he sells outside of EU ...

PixCanFly

Anyone using this 3rd party panasonic coupler? http://goo.gl/uydda

It's impossible to buy the original panasonic DMW-DCC8 in the market. I need to use the coupler with Switronix V mount solution http://goo.gl/Gc829

redpaw

@mrbill - sorry for the delay, just got the links from the guy who did the job for me. here it is: http://www.ebay.ie/itm/3pcs-2-5mm-DC-Power-Jack-Socket-Panel-Mount-Connector-/320743000585?pt=LH_DefaultDomain_3&hash=item4aadc5ca09

hope that helps

Howdy, Stranger!
