I'm always a little surprised that France never took the next step of the Messmer plan by electrifying road transport earlier. But I suppose it's so contingent on the 21st century battery tech.

Even 20 years ago batteries were advancing at a plodding pace. Things were just changing enough that you could build a smart phone, but battery life was by today’s standards low and charger anxiety was a real issue.

Nowadays I rarely carry a charger. On the either hand I am carrying several devices that are right on the knife edge of catching fire at any time

I’m honestly amazed airlines have not outright banned power banks given the risks. Like the Samsung Note that had a propensity for fires, and power banks seem universally less rigorously engineered.

I think people would just pack them into their checked luggage, where a fire could be much more dangerous.

I guess they'd lose customers if they banned Li batteries as almost everyone seems to carry them.

They do seem to have limits on their capacity.
