I had a convo today with Quantum Instruments about using one of their Turbo batteries to power a D4.

Might be a workaround for the reduced capacity of the new D4 battery (introduced I understand because of new regulations in Japan) compared to the D3/D3s, which some of us have got used to and may still need in some circumstances.

However Quantum are still waiting to get their hands on a D4 so cannot recommend anything yet.

I see that the D4 does not have an external DC-in plug which the D3s/D3/D3x have.
Nikon's own external supply for the D4 consists of a new EP-6 power connector which fits into the battery chamber, and EH-6b AC adapter which plugs into EP-6 one end and the wall supply the other. Hopefully Quantum can work with the EP-6...

Nikon's own website says that the old EH-6 power supply is compatible with the D4: http://www.nikonusa.com/Nikon-Products/Product-Archive/Power-Adapters/25282/EH-6-AC-Adapter.html#tab-ProductDetail-ProductTabs-CompatibleWith

Maybe that needs the EP-6 as well.

Update
======

There's a photo of the EP-6 on Nikon UK's website: http://www.europe-nikon.com/en_GB/product/accessories/slr/slr-power/ac-adaptors/ac-power-connector-ep-6

I suspect the hidden end of it has the standard Nikon socket for the EH-6 or EH-6b.

Yeah, but the point is that by using the Quantum you are not tied to a wall socket - its a battery pack. EH-6[b]+EP-6 doesn't give you that. On other websites there are discussions about the possibility of third party battery manufacturers supplying high-capacity batteries for the D4 (which of course could not be sold in Japan). The advantage over the Quantum is that they would be internal.

My (badly-made) point was that it looks as if the EP-6 has the same power connector as D3s etc, so existing Quantum cable would work.

By the way, my power pack is as follows
- Car battery
- 110V inverter
- EH-6

Not very efficient, nor portable, but lasts for ever.

Hey dormant - I realised what you were getting at after I pushed "post" ;) - sorry was on a do 10 things at once at full speed kind of day ;0
So, yes in theory it should work, still waiting to hear from Quantum...

Cheers

dormant, re your power pack - I'd find it hard to get it past security at events, but I like your style ;)

I guess a diesel generator as backup would make some impact too

Lol, that brings new meaning to the term "Drive through shooting"!
