Another calculator I have, is Casio FX-4500P. Havent used it long time, might be better to find new owner for it... Needs battery replacement, othervise ok (does not have plastic flip covers)

2 kW? Seems reasonable for a decent server.

If you type those formulas into the address bar of Safari or Chrome you'll see the answer live-updating as you type, with a delay of maybe 100 - 200 ms. So 2 kW for that time is 4000 J of 0.001 kWh (both answers obtained by live typing in my Chrome address bar). So that's something like a fortieth of fiftieth of a cent.

I'll take it.

Hah, I think it is changed since I last time used it, now with drop down menus and everything .. and it seems to be a local process, not a server side functionality.  |O I did pull the plug to see.  ;D

My only complaint about the HP48g and HP50g is that using them with hexadecimal is a pain.  I would not mind a more programmer oriented version.

At some point I had a TI-55-II which I replaced during early high school with a TI-66 which I still have.  Then Casio's FX-7000G came out which led to a funny story.  My friend Mike made me aware of it and I thought, "I have got to get that."  So that night I arranged to travel across town to BEST to buy the last one they had.  The next morning Mike tells me that he had planned on picking up the last FX-7000G available locally but some jerk beat him to BEST by about half an hour.

Later I moved to the HP48g with RPN and never looked back although I still have my TI-66 and a couple of LCD TI-35 derivatives stored with my slide rules for emergencies.

The TI-NSpire has good Hex and other non 10 based decimals options. Worth spending 10 minutes leaning how it's done.
As for the Google option, it's nice when you have it, but on site, with dodgy internet, not so good.
And if management caught us doing work calculations (fuel usage, fill rate, efficiency of x etc) on something that is not secure, like Google, not so good...

I still wish a manufacturer had an "unlimited version" of their top of the range CAS calculators with none of the educational shackles left. I think the HP 50g was the last of those.
Personally, while I do have a CAS app on my Iphone, I do find that a single purpose tool works better for me, less farting around.

Anything remote like Google or Wolfram Alpha is too slow and getting slower all the time.  I get by with Mathematica sometimes but that is local and even that is too slow unless it is already open and ready.

Plus RPN has a time saving stack.
