Glad to hear it works. BTW what was your typical 24-hour VD prior to this experiment? And did you have proximity lock/unlock and gear guard etc enabled?
You may want to post links to the products you used and which thread/post you're referring to. Also pictures of what your charger and setup looks like when it's all connected like might help. Without any of that, the only thing that comes to mind is possibly the wrong polarity being applied...
Very interesting, how did you get this data? So the 1.5/5.1 amps is coming out of the HV, correct? That would put it at roughly 2 kW (assuming 400V nominal for the pack) for running the HVAC (along with others), and roughly 600W without the HVAC. That sounds about right, and I assume a big chunk...
I don't understand why RANs and other charging spots don't also put a second sign plate in red lettering that says something like "EVs while charging only. $150 fine for violations. Towing Enforced". Why just use a carrot when you can use both a carrot and a stick?
To each their own, obviously. From my experience those who are bothered by vampire drain are typically bothered due to one or more of the following:
A. Camping out in the boonies for a week or two, and losing 6 mpd can mean the difference between making or not making it to the nearest charger...
Solar panel connects to OBD adapter via built-in SAE quick connects. No need for any other component. The Battery Tender was only mentioned as a separate indoor/plug-in option. There's an MPPT charge controller built into the solar panel that should regulate voltage.
The 12V systems can't be drawing 135 amps all the time, right? I assume you're referring to the maximum rating or something like CCA? My question was more along the lines of the actual/typical power usage when screens and HVAC are running. I'd have expected that to be something around a few...
Primary reason was efficiency, as has also been answered by others above. In my experience, it's been significantly more efficient to directly charge the 12V as opposed to energy going first into the HV and then DC-DC converted to the 12V. An order of magnitude (like 10x) difference in power...
Out of curiosity, does anyone have numbers for what the typical power draw (in Watts) is out of the 12V for various scenarios such as while it is idle or when HVAC /screens are running, with and without Gear Guard etc etc?
I went with the 3A just to buy myself enough headroom. The 30W solar panel is effectively a 2.5A charger under ideal conditions, so I figured a plugged in wall charger ought to have at least that much. I'm not sure when I'll use any of that extra capacity though, may be in cases where I need to...
My solar panel is rated for 30W, but it seemed to keep the 12V topped up during a mostly cloudy day, through a tinted windshield. So I imagine 18 watts might be more than enough, especially at night, when the vehicle is expected to be mostly left alone. If I can cut VD even by a half during long...

My name is blah-blah-blah and I suffer from VD (Vampire Drain, not the other kind thankfully :)), on my late-2022 Gen 1 R1T.
A few months ago I was facing 15-16 miles lost per day (despite Gear Guard being disabled and proximity set to Lock Only at home) at one point. The service center...
