The UK's consumer protection group, the Chartered Trading Standards Institute, recently purchased 400 counterfeit chargers online as part of an investigation into their safety.
Of that 400, the CTSI says that 397 "failed a basic safety test".
The CTSI explains how it tested the chargers, which were bought from eight countries around the globe:
Several tests were conducted including an electrical strength test in which high voltages are applied to the units to see how much voltage will flow between the input and output. If the current is above the threshold the unit is determined to have insufficient isolation with potential for electric shock. Only three of the 400 passed.
Earlier this year, Apple performed similar checks after purchasing chargers marked as being made by Apple from Amazon. In Apple's case, more than 90 per cent of the items purchased were fake. As a result, Apple filed a lawsuit against Mobile Star LLC, a company selling those fake chargers as real. In the lawsuit, Apple cited the UL who called some of the adapters "so poorly designed and constructed that they posed a risk of lethal electrocution to the user".
Even knowing this, it's striking to see that 99 per cent of counterfeit chargers couldn't even pass a basic safety test. This is undoubtedly one of the reasons Amazon is reportedly finally cracking down on fake products; these are fake products that could put people in actual danger.
I'll reiterate what I wrote back in October: Spending $45 on a charger can feel ridiculous (and yes, it is!), but its the one area where you really should be buying directly from the manufacturer or from a UL-certified third-party. Don't put yourself or your gadget in danger just to save a few dollars.
