Great, I'll use my old MacBook charger.
Oh no! it's a MagSafe 1.
I guess I'll get the slightly newer MacBook charger.
Oh no! It's a MagSafe 2.
I guess I'll use the MagSafe 3 that came with the new laptop.
Oh no! It's not there.

Those that bought a laptop with MagSafe 2 could use their MagSafe 1 chargers with an adapter. That was also something like 15 years ago since the change to MagSafe 2. Who is still using their Magsafe 1 charger besides me?

MagSafe 2 died about 10 years ago, and maxed out at 85 watts when newer Apple laptops started to use USB-C and come with 96 watt power supplies. The first Apple USB-C chargers were sized for something like 60 and 85 watts (same or similar to MagSafe 2 chargers) but they were replaced wit

I've been through the Lenovo series of connectors. I worked at Intel for 21 years and they were a Thinkpad/Lenovo house. I got my mother a Lenovo on the grounds they're a bit less prone to fall apart than other brands. Macs weren't in the running because she uses windows specific software. I have my yellow tipped barrel connector adaptor secreted in box for when the occasion to use it arises.
The (quite new) MacBook Air I'm typing on has 2 USB-C and one Magsafe 3. The real issue is I have only a single Magsafe 3 cable while I've got lots of USB-C chargers and cables so when the other ports are occupied, I'm schlepping off to find the one single cable. I tend to run lots of CPU heavy jobs, so it's the higher power brick for me.
But that ARM CPU. Ugh. I've hated the ARM instruction set since the Archimedes. It's not got better. They messed up the RNG instructions ( https://developer.arm.com/docu... [arm.com] ) stipulating 90C-RBG3(RS) structure which is the wrong choice for an instruction-as-full-entropy-source (Like RdSeed on Intel). The 90C-RBG3(XOR) is the right one since the RBG3 doesn't block the RBG2 with the XOR construction. RISC-V made the same mistake in their drafts, but they listened to my arguments and fixed it. ARM wouldn't give me the time of day and so here we are with broken specs for ARM. I wouldn't care if engineering RNG things wasn't what I did most of the time.
There's always the Framework running Linux when I want to retreat to my happy place. 6 ports, all configurable, X86 CPU and das blinken lights on the keyboard.

Great, then perhaps you could verify that I'm not hallucinating that when Lenovo switched to their "slim tip" power connector they were rated for 19 volts like the older "round tip" connector. Then would be the matter on if there was a difference in amperage ratings. I do not recall a "round tip" power supply rated for more than 65 watts, but higher power "slim tip" power supplies were in an abundance. Adapters existed between the two so something was keeping people from trying to use a 65 watt power sup

Yes. 19V. Like every other barrel connector powered laptop.

I've seen laptops with barrel connectors that used 12 volts, 15 volts, and other voltages. Maybe that's a matter of the laptops using older technology than lithium but not all laptops used 19 volts.
