That unit looks interesting.
I’d be interested in anyone’s practical experience in rough conditions.

Does anyone know how to charge Nikon batteries using a USB connector? When I'm camping in campgrounds with no AC hookups or remote locations I try to bring enough batteries to last me the trip but that is not always practical. I know I can bring a converter that I can convert to AC from my car battery but that means bring another piece of equipment. Is there a way I can use my USB ports in my car or a battery pack to run a battery charger?

I purchased 2 baggies with a USB charger from a company called Small Rig thru Amazon. They work with my D850 although they're third party.

USB-C charging mandate in EU active from 28th Dec 2024

www.theverge.com

The USB-C charging mandate arrives in the EU — here’s what that means

The direct aims to reduce e-waste and solve market fragmentation.
www.theverge.com www.theverge.com

"....An interesting wrinkle in this regulation is the EU hasn’t actually banned proprietary charging ports. Instead, hardware just needs the ability to charge via USB-C. ..."

Older cameras are presumably exempt, given the following exemption? :- " There are exceptions to this though. When it comes to products that are already in circulation, devices without USB-C ports that are placed on the market for the first time before December 28th can still be sold within the EU."

"....Another important, but less well-known, aspect of the common charging directive is around the unification of fast charging. The EU’s goal being the simplification of this oft-confusing practice. The governing body defines fast charging as anything that can be recharged via a wire with “voltages higher than 5 volts, currents higher than 3 amperes, or powers higher than 15 watts.”

"When devices hit this threshold, they must work with USB Power Delivery (USB PD), a charging protocol that enables devices to transfer power over USB in addition to data.... "

"...The elephant in the room is how the common charging solution is actually enforced. This will be down to the member states themselves, as they’re responsible for performing market surveillance...."
