Driver station power

However I agree this seems extreme and of course rules change. Those flashlights would not exceed the driver's station dimensions but we scraped it early on. It was for a camera tracking system we did not need.

Considering that a laptop charger is usually < 150W and < 30V.
I do not understand why anyone would need the sorts of current listed at the link.
If you must charge a laptop from a battery why not get a universal laptop car charger and put an Anderson Power connector on the end for a FIRST approved robot battery?
At least then you should have plenty of opportunities to charge that robot battery.
Plus handling the robot batteries is typical for this competition.
Plus a laptop charger meant to work in the car will not put out wall socket voltages.
So there's much less risk of some unusual accident.
Plus 150W max is no worse that 2 CIMs dragging on that battery.
Finally the custom electronics power supply on the robot would work at the driver's station (with less issues).

Course again it is entirely at FIRST's discretion if they allow this in future years.

I will also add that in past years while in various volunteer positions I've had the crazed experience of trying to help a team find a replacement laptop battery at a competition (laptop batteries are not cheap and the software just takes hours to install). Lucky for those that got one I have several friends with computer stores and piles of questionable laptops they can part for a used spare. Usually my friends have been good enough to just give them the battery which is generous considering it's a zero notice demand and sometimes they've even delivered it (hey that was not 30 minutes or less ).

I myself have a universal car charger with an Anderson power connector and a few tails just in case something like this happens. I come prepared (I even lately bring a spare dual core laptop suitable as a driver's station with most of the software and updates installed) and the mess stops with me. However I would never offer this up as a solution without confirming with the field crew they understand what is going on (even if the rules might allow it in any given year).
