Can I retrofit old Dell AC Power block with a USB-C tip for my new Lenovo?

My work gave me a Lenovo T480s laptop which charges via a 65W AC Adapter which has a USB-C tip. I need extra chargers - home, office, car... can i take my old Dell 65w chargers and just cut and tape/solder on a USB-C tip? It's a shame to waste the older chargers and pay for ones

you also need to compare all the voltages not just 65watts to see if it will be compatible.

+1. I wouldn't risk it. Just ask office to order 1 more charger. I had 2 when I got my work laptop. My boss ordered 1 extra for us.
I hate to speculate. I hate to forecast. I am just proactive.

A lot more than just the physical tip goes into what you are thinking can be done. There's a lot of circuitry for USB-C to work so that it can be multi-use.

If you are set on re-using those old DELL chargers, I would look for a USB-C power supply circuit board or kit that doesn't provide a power source and then see if your existing DELL power bricks can supply power to that USB-C circuit.

Something like this - https://www.coolgear.com/product/usb-ca ... pcb-ccg3pa - may be suitable for your purposes.

Question: Are you asking because "common sense" is suggesting that it may be plausible since they both are laptop adapters and both rated @ 65 watts?

This.
Notebooks have a wide variety of ranges of voltages that they operate on and don't like what they weren't designed for.
This will be a much bigger battle than it seems.
Do you not have anything else to do rather than argue with strangers on the internet
Nope. That's why I'm on the internet arguing with strangers. If I had anything better to do I'd probably be doing it.

I assume that since the wattage, volts and amps are the same, that it's just the tip and splicing two wires together
