The Air India clock was made for automotive use. That's why it could run on a 12-volt lantern battery.

You got a link for this? I read somewhere that the Air India clock was a Micronta like the Texas kid's. And aren't most lantern batteries 6V?

It was. But it was a different type than Ahmed's.

They are. But 12-volt lantern batteries are easy enough to come by.

$10.84 at Zoro.com (cheaper than Amazon). 5.25" high by 4.875" wide by 2.875" deep — a bit bulky for Ahmed's Walmart pencil case, I'd say.
