I still have an old TI calculator somewhere (red LED, with a bubble lens over each digit). That thing would churn through batteries pretty fast, but has a port for an AC/DC adapter (wall wart). It was my main calculator in the shop for a while. :D

I remember my first Texas Instrument electronic calculator - an SR-10. It cost about $100, got it at Sears, had the four basic functions, sqrt, 1/x, etc. - about the same as what you give $1.99 for at the Dollar Store today.
I still have my first calculator that did more than simple math. Haven't used it in 30 years. Went out to the shop, got it and it came on! That's one heck of a battery.

I had the plastic pencil case with sharpener,,,
It had a sliding view-port that revealed the multiplication table in it up to 10 times 10.

It helped me memorize the table in record time.

My first electronic calculator was bought at the Shepard AFB BX in 1971,,,
Texas Instrument SR-7 (slide rule seven function) for $119.95,,,
It had a power cord and voltage adapter (no battery).

There's one on my desk right now that has all those functions as well as Memory +-,,,
Solar powered that has lasted me over ten years,,,
Bought it for a buck at Wal Mart.

The Air Force tech training taught me how to use a slide rule,,,
But after tech school I never touched one again.
