It would take more research, but perhaps Jackery is doing the very same tests and Dometic is just better at writing manuals? Obviously nothing can get moved without certain certifications.

That's what I first thought but I don't have the actual UN 38.3 but Intertek (the company Dometic even lists as doing it in their manual) says about it. UN 38.3 It is important to note that lithium batteries have been identified as a Class 9 dangerous good during transport. To be safely...

Indeed I had a typo. I noticed that UN 38.3 in their manual and found it interesting. MIL-STD-810 (in the U.S.) would be beyond that in some ways but very similar in concept. It's actually what I had in mind some pages ago when I mentioned that going from no design or test standard for...

Rim offset definitely has an affect on geometry, specifically the scrub radius and inclination angle. Adding offset (e.g moving the tire out) will change the center of the tire contact patch out relative to the pivot point. Going out makes scrub less negative and potentially go positive, which...

A nice thing to see is that the Dometic tests to UN 38.3, which is a standard for transport of lithium batteries. It would nice to know for sure that means the unit itself and that it was all the tests. There are eight - shock, vibe, impact being important here - but also overcharge, thermal, etc.

Fitting the connector housing is to some extent the quality of the cable itself. Some manufacturers will use very thick insulation to give the cable a substantial feeling or, worse, not actually be 10AWG conductors and use extra thick insulation to make it seem like a heavier cable that it is...

Updating this thread since I've had a Connect Systems CS800D dual band VHF/UHF for a couple of years now. It works fine, no major issues. Small firmware glitches that get fixed pretty quick but like many things cheap (although I'd suggest moderately priced in this case) Chinese radio the major...

With old, rusty Toyotas that's usually correct, though. Maybe not so easy on the Jackery to blame rotten bolts in the frame and what not.

@Martinjmpr, you could substitute that story for just about anything. Just this week I helped my neighbor turn on her swamp cooler and deal with her overheated car. She's probably no different than most people who have no idea how things work and rely so very heavily on specialists...

It works both ways. In competitive markets if the consumer demands honesty they get it. You and I live in a place where price mainly drives the bus so we get a race to the bottom for the most part. But there still exists a small market segment for things described accurately and completely...

As far as I can tell it's not possible to use Gaia in real time on my Mac using a USB dongle. The limitation is with Gaia. It's running on a website, not an native application, and while the browser (for example Safari) could I suppose use Location Services the Gaia web app doesn't attempt to...

When you watch tear down videos of these Jackery devices they do look to me to be built reasonably well. They are not military grade and are obviously not ruggedized as such (e.g. not conformally coated, no real attempt to protect from shock, vibe or anything). But they don't look particularly...

I meant it's a curse carried by us (some anyway) as a desire for correct terminology. We're not robots (yet) so each individual professional will of course have a different tolerance to a layperson using a term casually. And you're right about amateurs sometimes besting pros. Not having...

Those portable power boxes use lithium batteries that aren't necessarily directly compatible with things designed to plug into 12V vehicle stuff. I'm pretty sure Jackery is using lithium-ion cells to make up a battery which will either be too low (around 11V) or too high (around 15V) to use...

I'm curious, too. The only thing I can remember Gaia using from ESRI was their shaded relief overlay and that's been a few years ago. There could be unknown subscriber layers, though.

The only reason I can see is if the battery didn't happen to have a compatible chemistry or management system and was thus unregulated with an excessively high voltage. But that won't be the case with a LiFePO4 Battle Born. You will need a 12V-5V USB adapter, though.

@OllieChristopher, it's the curse of STEM to be sticklers for terminology. If you have to keep starting at zero defining terms you never get anything done. Still, the beginning of a technical paper or book will contain a list of terms and abbreviations because, you know, can't ever be too...

The regular old Gaia Topo usually with the USFS 2016 turned on. Living in the desert with BLM land all around that's the best option I find. Gaia's map pulls in OSM data, which is usually about as accurate as anything.

Having portable 12V power is handy. I usually have a couple of extra batteries around just for stuff like that, which are bigger and heavier than a pack like this. I can totally see the utility. I have dual batteries in the truck and probably wouldn't drag a portable pack over a few extension...

Oh, yeah, I know it's a business decision mostly and could be consumer-friendly. The oil change interval on my Tacoma is 5,000 miles before the "maintenance required" light illuminates. It requires holding the odometer trip reset down when you turn the key to on and letting odometer read out...
