BS!
And you know this is "BS!" exactly how? Did you test all 400 of the ones that the British Consumer Safety Organization tested? Here's another report:
UL safety testing shows 95 percent of counterfeit iPhone chargers lack safeguards, are unsafe

AppleInsider, December 2, 2016A commissioned report of 400 fake Apple chargers bought from all over the world found that 99 percent of them were unsafe, and didn't have sufficient safeguards to protect users and plugged-in devices.
According to BBC News, Underwriters Laboratories (UL) applied high voltage to the chargers to test for sufficient insulation and other safeguards. As a result of the testing, the agency concluded that unknown chargers purchased online were an "unknown entity" and hazardous.
The chargers were purchased from vendors in Australia, China, and the U.S.
In October, Apple started stemming the tide of counterfeit chargers, and sued vendor Mobile Star, accusing it of violating copyrights and trademarks by selling counterfeit accessories on Amazon and Groupon. The suit specifically targets 5-watt USB power adapters and Lightning-to-USB cables sold by Mobile Star, the same as those cited in the BBC News report.
Apple said that it discovered the issue with Mobile Star's gear as part of its regular efforts to combat fake accessories.The company notes that in nine months, it bought "well over 100 iPhone devices, Apple power products, and Lightning cables sold as genuine" through Amazon's "Fulfillment by Amazon" program, and found that almost 90 percent of them were inauthentic.
In 2012, engineer Ken Shirriff examined Apple's chargers, and found them to include better and safer components than knock-offs. A year later, Apple implemented a fake charger buy-back program, which appears to still be operating.
That's the Underwriters Labs (UL) weighing in on the same issue in the US. Now, are you STILL going to cry "BS!"?
I’ve had a crappy experience using the knockoffs. Usually it’s the wiring getting frayed at the connector end and eventually not working. It’s much more expensive getting the genuine Apple charger but they never have a problem (except getting lost).
