Rumor has it that they had to truck it back to Fremont to recharge it. It is supposed to return to SLO for the Sunday rush.

Tesla Mobile Supercharger - Battery and Pedestals on Trailer
- Thread starter Remonster
- Start date
In the other thread on this thing, someone said that they got a starting charge rate of 120 kW. So, while it clearly uses the urban posts, it's not limited to the urban power rating. IIRC, the Teslarati article said that they thought it would be capable of charging 100 cars before needing to recharge the batteries. For 3 MWh of battery, that's only 30 kWh per car. That seems low for this particular usage case. For things like temporary placement in areas affected by widespread utility blackouts, that might be a more reasonable number if the goal is mostly just to get people out of the affected region and to the next open charger.

That is how Tesla handles adversity, like this earlier in the day.

While you're doing admin duties Bruce, do you mind editing the title to say "3MWh"?
Done!

This time they charged it off the local Superchargers.

If true that’s so dumb, might as well have a diesel powered generator charging the batteries instead of trucking it back and forth
Apparently Tesla brought one of their Megapacks to the Thunderhill Raceway in Willows CA for some testing reported by Salomondrin on YT.

That's not a Megapack. Significantly fewer batteries on this one than the Megapack one. That looks like a smaller, cobbled together set-up consisting of just a few Powerpack batteries, an inverter, and a mobile supercharger pallet. The Megapack version also had a bunch more charging posts on it.
That’s an odd reasoning. Just because the appearance is different doesn’t mean the concept is as well. The Megapack is still charged at an existing Supercharger location to obtain the power it needs to then Supercharge other vehicles. I don’t if anyone actually saw under that white box on the trailer so I can’t say we know what’s under there for sure (unless I’m wrong).
The charging ports argument is also completely irrelevant, just like that. Sorry, but that’s like saying a 2-stall Supercharger isn’t a Supercharger because it doesn’t have 8 stalls.
Anyway... I’m past my bedtime, so that’s probably why I’m a bit cranky. Good night...
Of course it's the same concept--batteries powering a temporary charging station. My point is only that this isn't Megapack-based. Megapack is a 3 MWh battery system. The one shown in these pictures is capable of storing less than 1 MWh. I don't know whether the big mobile charger system that was debuted over Thanksgiving had the full 3 MWh or not, but it clearly was much larger than this one in terms of form factor. Also, the chargers were hardwired to the set-up, as opposed to being independent mobile pallet superchargers that are wired to draw electricity from the battery system.
Same general idea, but different implementations.
