Sorry, no.
Safety costs money. The fuses and microprocessors that prevent the thing from sparking or trying to charge a shorted circuit increase the cost of a device. So the cheap knock off manufacturer is always going to leave as much of that stuff out as they can get away with. And China doesn’t give a shit about regulating their industries, they only care about supressing dissent.
Sure, you could make a safe knock off charger for say $20, but then you’d be competing against the unsafe knock offs selling for $10, nobody would buy your safe ones, and you’d go bankrupt.
