I had a 1978 MG that had a starting threshold of 18 degrees F. Any temperature below that and it wouldn't start.
Worst choice in automobiles I ever made considering I live in Michigan with winters.......
12 minutes approaches being tolerable. Pull up at a highway rest station, plug in, use the rest room, grab a coffee, and head back out.
I wonder how many charge cycles before the battery needs replacing?
Not a funny video...but still pretty incredible...
There are plenty of “mobile device sized” solar chargers available.
The problem is most are too small, and regularly exposed to insufficient light, to charge a phone.
I do keep this in my backpack at all times, solar charging the pack when prolonged direct sunlight is available, and for emergencies where other options simply don’t exist:

4 AA rechargeable batteries (for flexibility), enough power to fully charge most phones at least once, small enough to easily keep in a backpack, large enough to charge in direct sunlight in a few hours, can connect phone directly if needed.
(Anything smaller than this is a novelty that will frustrate you.)
“I had a 1978 MG...”
Reminds me of the Austin Healey 3000’s that I owned. If it rained...you got wet; in the summer...you roasted. Of course, the heat output was great in the winter if you could handle the frigid cross breezes from the clattering slider windows.
But then...they were classics.
This is a point that most EV-naysayers don’t grasp: yes, charge times still don’t compete head-to-head with refilling a tank of gasoline, but battery technology is improving that recharge time substantially. Gas refill takes about 5 minutes; >15 for EV is basically the break-even point, considering that most of the time you’ll have it fully recharged every morning (charging overnight at home) - I’ll put up with a 15 min “refill” if I don’t have to do it nearly as often as a gas car.
Apple will come out with this in a few years and then sue Samsung.
I've used the Nektek extensively over the past 1 1/2 year for Garmin GPS, camera batteries, cell phone and small tablet as well as other devices in the field. At $50, a bargain. Can charge cell phone and Amazon Fire 7 directly, but most effective charging a power bank like any of the Anker 10,000 mAh USB battery units over the course of the day. Available about $40 or more depending on unit. That way you provide a steady charging current independent of the vagaries of solar source, clouds etc.

Anything less than 20W at 5V is a waste of money. BTW, nearly all of the tiny solar/crank radio units have woefully inadequate NiCads and produce just barely enough energy to provide only a few minutes of telephone time for cells. Radio reception lasts a bit longer but expect weak reception.
No, in fact I never heard of one till you mentioned it.
In my pants pocket?
One-two
One-two-three uh!
Hot pants, hey hot pants uh! Smokin'
Hot pants, smokin' that, hot pants …
In Winnipeg it gets so cold lots of cars have block heaters that they plug in at home. I read somewhere that they have power sources for block heaters on parking meters so that if you try to park for free or your time expires for long enough -— hey, frozen motor, eh?
I always wondered if he got a negligent driving citation for that; the lack of care seems to fit the charge.
My Buell would take a comparatively glacial 3.4 to get to 60, but even I know you don’t do a burn out on a pro-stock class bike except on a prepared drag strip just as though you were going the full quarter mile. And racing suit and helmet helps.
I think the bike zoomed forward with sudden traction and he inadvertently rolled the throttle on with the Gs of acceleration.
The video has been out a couple of years, but it’s stuck with me. The wreck was horrible, but the power of that bike blew my mind.
Since it was a British crap car, I suspect it was the battery’s fault since I would have to get a jump start to get going.........Whatever, it was a piece of crap........
Based on the SEM image, I’d guess that the improvement is attributable to vastly increased anode surface area...
Discharge rate is generally gated by the impedance of the device ("load") drawing current from the battery -- not the battery itself.
Cost?
