We seem to have a lot of problems with genuine Apple power supplies for our MacBooks failing at the spot where the cable enters the case. So I've got some questions:
Suggestions for best practices for keeping the power supplies alive?
Are there alternative power supplies that are either more robust or more repairable (either from Apple or from third parties – for example are the original MagSafe supplies more durable than the MagSafe 2, or vice versa)?
I'm getting tired of replacing these technological wonders…
Our failures are worse than shown in How to fix a frayed cable on a MagSafe Power Adapter? when we notice them… The current one is at the point where I can't reliably get the cable into a position where it works – which is what I think it would take for the methods suggested in the answers to this question to work.
