If only he had put a hat on it like mine ,or at lease vaseline or something over the screws {Just had to replace my charger as the old Ohme was faulty. Little tip cover the hole at the top with something as the screw rusts really bad. I had to bend the whole unit and crack the plastic to remove from the bracket as I couldn’t get the screw out due to rusting.}
Your not having much luck with chargers buddy lol.
I fill the rawl plug with silicone then silicone over the screw hole to make watertight and then put a neat bead of silicone along the top and sids of charger. Never had an issue 🙂
