Where can I find a Razer blade charger that works

I have a 2019 Razer Blade that I am trying to keep alive for as long as possible. Unfortunately, in the time I have had the laptop, the charger has become seriously frayed where the bend next to the block is (stupid design imo) - with wires now being visible.

I have previously bought an unofficial charger because it was such a hassle going directly through razer themselves and the prices were steep. However, the one I bought off amazon is dreadful with constant connection issues and overheating.

Has anyone had success either repairing the charger if this has happened to you, or found a suitable alternative that works well?

Thank you
