This makes no actual sense as a complaint.

The M-series all have chargers with a USB-C socket on them that the cable is plugged in to, so you would have been able to use the PSU from any M-series MacBook - even if they were the models prior to magsafe being re-introduced.

The magsafe in the M-series is not the same as magsafe 1 or 2, so they are not compatible and you would have needed to buy an adapter (and I have no idea if Apple has even made a first party version of this.) So you'd need a new adapter.

On the other hand, any USB-C charger that delivers the right voltage will charge the Neo.
