I’ve been using ‘magnetic tip cables’, including Apple’s laptop MagSafe and old USB-A magnetic tip cables from generic brands, not knowing the full risks of what they entail. Before I get into the story, I do want to make one thing clear: Apple’s MagSafe is safe. It’s not the reason why I am writing this piece, but there are products advertised to mimic MagSafe for laptops, so do watch out.
