Where can I now find a "snuglet" for my MacBooks (Pro & Air)?

Some of the the devices you posted were MagSafe 1 to MagSafe-2 adapters, that allowed old power adapters to be used with MagSafe-2 devices.

The MagSafe used on modern MacBook Pro is MagSafe-3, and there is NO adapters from older adapters to MagSafe-3, because the handshake protocol is different.

However, as IdrisSeabright observed, most Macs that feature MagSafe-3 can also be charged with the right USB-C cords, BUT: Choose carefully!

Standard USB-C cord can charge at 60 Watts power level, whcih may not be quite enough for a 15-in or larger MacBook Pro. Premium USB-C cable may be rated for 100 Watts power, and super-premium cables for up to 240 Watts power.

Isn't that the whole point of the magnetic connector? It's supposed to detach easily so that your computer doesn't get dragged off onto the floor if the cable is pulled on?

I've never heard of a "snuglet" before so, unfortunately, I can't give you suggestions on where to find something like that.

Credit goes to leroydouglas. I learned something new!

Thanks for clearing that up.

At least one of the links in the OLD discussion posted was a MagSafe-1 to MagSafe-2 adapter available from OWC/MacSales, currently out-of-stock

Never having experienced any shortcomings of MagSafe connections of any kind, I assumed ALL were those MgSafe 1 to magSafe-2 adapters.

I stand corrected again.

My hat's off to you again!

The MacBook Pro was purchased new, this March, from Apple. Would it not come with the proper charging cable?

It did come with a proper cable, just not the one you prefer.

I stand corrected.

kudos to leroydouglas for pointing that out!

i remember something historically... there was some slop in the old connection somewhere along the line
