Dangerous USB phone chargers 5 (Quick 18W QC 3.0)

Another collection of dodgy USB phone chargers from eBay. This time a quick charger edition. Three cheap USB chargers that support 18W QC3.0 charging and they can supply 5V 3A, 9V 2A or 12V . Some of those cheap chargers may not comply with safety regulations and they may cause an electric shock or fire. They also tend to have a non-existent interference suppression, poor output voltage regulation and a fake current rating. Please support my channel on Patreon:
