2014 power adapter extension cable compatible with 70W USB-C Power Adapter

Hi there. I just got the new 2023 macbook Air 13 inch M2 chip. It came with the 70W USB-C Power Adapter and USB-C to MagSafe 3 Cable. Unfortunately no extension cable was provided.

My old MacBook Air (2014) came with a 45W MagSafe Power Adapter with MagSafe 2 style connector and power adapter extension cable.

Can I use the old power adapter extension cable with my new 70W usb-c power adapter/usbc to MagSafe 3 cable?

The Apple website does not specify whether this is okay to do.

Thanks so much.

MacBook Air, macOS 14.2

You can use the older extension cord. It is more than adequate for 70 watts.

Also see the following from Power Adapter Extension Cable - Apple

The 1.8-meter Power Adapter Extension Cable is an AC extension lead that provides extra length for your Apple power adapter. Use it with MagSafe and MagSafe 2 power adapters, 10W and 12W USB-A power adapters and 29W, 30W, 61W, 67W, 87W, 96W, and 140W USB-C power adapters.
