Counterattacking the counterfeit

February 10, 2017

Everyone loves a bargain, so I am sure from time to time; we have all bought a cheaper version phone charger for your mobile. However a massive problem nowadays is counterfeit chargers for portable electronic devices. At the end of last year, Apple claimed that of 100 Apple-branded charging accessories it bought on Amazon, 90 were counterfeits. Around the same time, Britain’s Chartered Trading Standards Institute reported that of 400…
