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

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

i wouldn't do it myself, but i want to see if it's possible. OP give it a shot, it's only work laptop, not yours, lol

+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.

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.

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

UPDATE: It doesn't work! D'oh
