I agree with
@Pugs1957.
you don't have to buy the best charger... but if you don't have already a previous generation Samsung charger, then at least buy something from a reputable company that deals in chargers and batteries.
Companies such as Anker / RavPower have good heritage and knowledge in battery manufacture and charging.
why chance your £1000+ phone with a cheap charger that may not have a good protection circuit.
