I generally get well more than eight hours overnight while away on expeditions, last year I followed the Scottish Six Day Trail for two days and took a lot of exposures with the D3 using four batteries. In car charging would have been a boon. I don't trust inverters, especially cheap ones when it comes to expensive camera and computer gear.  So for me at least, the ability to charge a camera battery from the car would be welcome.  Meanwhile one of my D3 batteries had died.

I had planned to repeat the trip and get four days of the trial this year but covid19 got in the way, maybe next year?

I suppose that is fair enough but that wouldn't be charging in your car would it?

As soon as there is more than one battery involved I would prefer to use a separate charger. Charging a battery in the camera overnight would probably work with the Z6 or Z7 if the external charger has only one slot, one charging in the camera and one in the charger to start the day with two fully charged. The D3, and later, SLRs have two slot chargers allowing one to start the day with two fully charged batteries and no need to use the camera.

It is possible these days to buy a third party charger for Nikon batteries (I have an MH26 equivalent) and some come with adaptor plates to allow both EN-EL18 and EN-EL4 batteries to be charged. I haven't tried one with an inverter but I have used an inverter with computers without problems.

I have several ExPro EN-EL4a batteries and I can't fault them and they ate 1/3 the price of a Nikon original.

I am still looking for a dual battery charger that charges both/two EN-EL15 batteries simultaneously rather than sequentially.  This is a design item not an electronics limitation.

Nikon dont make a two EN-EL15 battery charger but there are chinese variants that offer this but they run on 5v USB charging which takes forever to charge two batteries.

Wow.  So exchange the plates for different batteries at approx £5 each!

Well spotted JK, nice one.

What I need is an external power source for the D800, I ran a time lapse yesterday for 5 hours continuous, I used a battery base screwed to the bottom of the D800 with a second EN-EL 15.  It just managed the 5 hours, I doubt it would have done 6 hours.  What I would much prefer would be to be able to plug a large capacity battery into the DC input port.  For time lapse and astro, compact and built in don't count highly.  Long, uninterrupted running time is paramount.

Unless you want to operate remotely from mains power this is what Nikon offer EH-5c/EH-5b AC adapter; requires EP-5B power connector (available separately). However, I suspect the EP-5B is rather overpriced (£40 on Amazon).

I have had the EH6, originally for the D2, for many years but the adaptor to use it with the D4 is more than I paid for the power supply, around £150 when I last looked.

I have a mains PSU for the D3 and one for the D300, not sure that either of these will fit the D800, I will check.  My plan was to find a (relatively) large capacity battery and cut an appropriate plug off of a mains PSU to provide the connection to the camera, I can use an appropriate plug and socket to allow the lead to be re-attached to the appropriate PSU.

However that is a winter project...

I would guess 90% of my time lapse or interval photography is remote from the mains.

It is completely beyond me why you would charge via USB when the charger does it in 90ish minutes compared with overnight (approx. 8 hours).

'Raises hand' ... so I pretty much exclusively charge my Z6 batteries via USB C.

The answer? Convenience. 

I pretty much exclusively use the camera with the MB-N10 grip, so have 2 EN-EL15b batteries inside it. I do carry a couple of EN-EL15a spares if I expect to be doing a lot of filming, but mostly the two in the grip are just fine.

I have a lot of tech so the main chargers I use are fast USB-C PD ones, and they are always plugged in, I don't keep chargers like the dedicated Nikon one plugged in. So at the end of the day, I plug the camera into a USB C charger, leave it overnight, and both batteries are good to go the next day. If moving between locations and expecting a long day of shooting, I'll plug in a USB C cable from my backpack that I have a powerbank in too, giving me a nice little boost if needed.

Well there you go......
Just proves the point that not all/some features are useless even if we dont use them as somebody else may have found it useful.
:applause:
