Good find, very interesting. Obviously a unique special case with controlled conditions, no drop offs here and there, etc. Would be neat to find out what their design restrictions and ideas were. Quite rare overall facility I'm sure.

How then is 24VDC changed into 12VDC if not by a transformer? That was performed on commercial bus's 50 years ago.

The 24V vehicle I had used two 12V batteries. I got 12V by connecting to just one of them.

Note that the Californians don't mind all that water going through turbines on the Columbia river between Washington and Oregon rather than bypassing it. They'd rather kill more salmon as long as they get their electricity for EVs so they can be so green. Amazing. Sorry, I digress. Back to jumper cables.

I have a similar setup on my older F350 - 2/0 all-copper to anderson connectors at the front and rear bumpersView attachment 2100674

can connect winch or jumpers to either end very quickly without looking at a battery.

Very kool.

Personally I feel Jumper cables are a waste of time anymore. I own a pair, Don't even know where they are.

yes they are cheaper, generally but it does require another vehicle or machine be able to get close enough to jump, that doesn't seem to happen for me most times.

lithium based battery jumpers are substantially quicker and easier to use, yes they cost more and you have to watch the charge on them, but unless your planning on cranking for 20s. they seem to be easier.

I want one, but there’s so many choices and conflicting reviews.

I had the big, heavy, old fashioned one that worked on gas engines, but was of little use on bigger diesel engines. Then someone stole it off my truck. Probably did me a favor.

I bought one of those new fangled ones for about $140 about a year and a half ago. It won't touch my diesel, but does start my MIL's Toyota. I use it for lawnmowers and such mostly, and when something else a little bigger around here won't start, I grab my jumper cables and pull the pickup over near it. At 20 foot in length, I can pretty much reach any battery from where I park anything else. However, if I can't..., then I just clamp the two sets of jumper cables together to make 38 foot. Due to the size of that wire, I don't notice any voltage drop, but even if there is some, it still beats having to keep that little electric box charged and hope that it isn't gone off somewhere in the Wife's car when I need it at home!
Jumper cables don't require any maintenance to make sure they are charged in case you need them, but if you go out places where there isn't anyone else around in another vehicle, then a jumpbox might be a good option.

I somewhat agree, BUT, not every vehicle just fires up in the 2.5 seconds the jump packs give, and then it has to sit for like a minute before you try again. I think this is a both, more than an either or

I made a set of jumper cables over 25 years ago using 1/0, fine strand welding cable. The reason for the wire size is that they are long enough so that vehicles can be rear bumper to rear bumper and I made them that long because I had experience with a situation where that was the only way, so that means they are around 30 feet in length. I picked up the wire for free, at the time I was working in a factory that made wire and cable.

I can't remember the last time I used them. I stopped using them after I purchased my first jump starter. But I would never part with those cables.

I have both types of jumper boxes, the compact lithium and the older style with a gel/agm battery in them. Neither of them seem to work well on diesels with manifold heaters or glow plugs. I have used a pair of the older style before at the same time which did work. After a whole bunch of farting around in the cold, it would have been much easier to drive back and get the heavy booster cables and sit in a warm pickup while the other battery is getting charged up.
I also have one set of old heavy welding cable jumpers and a couple of pairs of newer ones that I have received over the years as gifts.
Cold weather diesel starting I don't believe those fancy lithium booster will work worth a damn unless they are very expensive extremely high amp ones.
All the testing I have seen of those compact ones are just turning the starters over in decent weather, I have not seen one being drawn down like glow plugs or manifold heaters would do then cranking a cold engine over.

Edited to add, the good booster cables are not cheaper then the boost packs.
