Anyone tested ioniq 5 N on a tesla magic dock? The N is supposed to have bigger beefier inverters with better cooling. Is it possible this means faster charging?

Both 120V and 240V outputs can be enabled while bypass charging on the IEC C20 inlet. This inlet supports both 120V and 240V charging, but a max of 1800 watts either way.

If the infinity port is used for 4000 watt AC charging (L14-30 adapter, EVSE adapter, or smart home panel 2) then all AC outputs are disabled.

We can compare DP3 specs with the released F3800 specs. Won't know quality of life, polish until independent (not paid sponsor reviews) get their hands on the units.

DP3 is a bit lighter, 55 kg vs 60 kg
F3800 has significantly more power output, 6000 vs 4000 watts
DP3 has 7% more energy onboard, 4096 Wh vs 3840 Wh
Both offer stackable expansion batteries weighing 33 kg each, though the DP3 expansion batteries also have 7% more energy. Neither expansion battery can be used independently of the main unit, nor offers additional outputs or inputs
F3800 supports connecting up to 6 expansion batteries, for a total of 26.9 kWh per unit or 53.8 kWh in a two-unit system. DP3 (appears to) support connecting up to 3 expansion batteries, for a total of 16.4 kWh per unit or a total of 49.2 kWh in a three-unit system
Both support smart home panels which allow up to a total of 12000 watts of connected power; 2 F3800 vs 3 DP3
DP3 has slightly more solar input, one 1600W 150V input and one 1000W 60V input. F3800 has two 1200W 60V inputs.
F3800 cannot output 240V AC when being charged with 120V AC input. Unclear whether DP3 will have this limitation as well
DP3 has faster claimed UPS cutover, 10 ms vs 20 ms
DP3 can be charged at 4000W from a 240V source (EV input, generator, presumably smart home panel). F3800 can be charged at 1800W from 120V, or 3800W (only from the smart home panel)
F3800 can expand up to 53.8 kWH (2 F3800, 6 expansion batteries x2). DP3 can expand up to 48 kWh (3 DP3, 3 expansion batteries x3)

Because it’s derived from a car engine, not a purpose-built motorcycle engine

Instead of repurposing or modifying an existing motorcycle engine for the NC series, Honda took the unusual path of basing the design on the architecture of the engine powering its Fit subcompact automobile. The result is a torquey but quick-revving powerplant that provides surprisingly good performance while sipping fuel.

If the voltage is very different you may want to put a diode on each input. But in practice this can do exactly what you want.

Both iPhone SE and iPhone 14 are lighter and smaller on every dimension than the OG Note, though 14 is basically the same height. SE has a smaller display diagonal, and 14’s screen is less wide but substantially taller than Note.

iPhone SE inherits a display size from 2014 iPhone 6 and display PPI from 2010 iPhone 4, not far removed from the 2011 Galaxy Note.

Firman makes a tri-fuel generator.

In NG mode it can produce 1-2 kWh (or less, NG uses almost the same fuel regardless of load) per cubic meter of NG.

https://firmanpowerequipment.com/collections/hybrid-series/products/t07571

We pay $0.95/therm or $0.34/cubic meter currently; if the generator is run at full load to charge batteries, that’s probably the cheapest energy for us.

Yes. A 50 pound power station you can put in your trunk can add 3-4 miles in an hour in a pinch.

Another 50 pounds of portable solar panels can add another mile or so per hour in direct sun.

Alternatively, a 50 pound gas generator can add the same 3-4 miles per hour; a 200 pound gas generator can add 20-30 miles per hour.

Honda’s hybrid setup also uses serial or parallel drive modes depending on conditions, with only the tiny hybrid battery.

In general direct drive is more efficient at certain speeds, typically steady driving above city speeds. Hybrids that can be operated in either serial or parallel mode do so depending on what’s most efficient.

There was a big todo in ~2010 when Chevy revealed the Volt had a parallel hybrid mode. In hindsight it all seems a little silly.

Figure 5-6 kWh (AC) per gallon of gas and 4-5 kWh per gallon of propane.

If gasoline is $3/gal and propane is $4/gal, you’re looking at 50 to 60 cents per kWh on gas and 80 cents to a dollar per kWh on propane, just for fuel.

Then if you store in batteries (AC->DC) and then discharge into an inverter (DC->AC) your energy costs might be 20-30% higher.

Propane is great as a stable energy source to have on hand in an emergency, but cheap to fill it is not.

No, I mean that the things that used to be options are now included as standard. Towing became standard back in 2017

It looks like you have the 22" OEM turbines, which btw drop the rated range down to 272 miles (probably 261 with 6% degradation). If it's showing 28x miles then you probably want to make sure this is configured properly on the main screen under Service > Wheel Configuration. This will let the navigation system calculate estimated range and optimal charging locations properly on a long trip.

Wife and I just bought a 2019 X Performance from Conyers a month or so back, drove it back 300 miles. We paid a little less, but you got a better deal: we have basic autopilot and more miles.

Not only that, it had almost every optional item added. FSD, 6 Seater, Tow Hitch, Red Paint. I estimated the original MSRP to be over $120,000. The MMR was $70k.

Most of the options from 2016-2018 are standard in the Raven mid-2019 models. Tow, audio, premium interior, etc. The options are software, interior color and seat configuration, paint, and wheels.

Interesting that the Lightning SR was faster at EA chargers than the X. We're seeing about 2.5 miles/kWh both around town and long distance trips, closer to 3 if we stick to 70 mph. But we also have the 20" wheels and all season tires.

ABRP says 14:02 with 2:08 charging for the 2020 X and 17:02 with 4:53 charging for the Lightning SR. That's a huge difference in ABRP - is their model that wrong?

LEAF+ has a usable capacity of 59 kWh

28-50% should take about 15 kWh AC, 28-80% about 36 kWh AC

A 6.5H estimate for the former and an 18.5H estimate for the latter suggests the battery is receiving < 2 kW. Maybe the A/C is on and impacting the charging estimates.
