In somewhat greater detail:
The CE mark on it because the ink is not worth it. There are also no "CE certification" as it says in the article text, since CE is a manufacturer's declaration. Ie as certified checks and no one but the manufacturers themselves. Or maybe not.
This device would never pass an EMC test. The conducted emission was measured in the laboratory with a broadband 25 dB above the limit, which is much higher. That way, together with all devices of this kind that I had been in the fingers, and is also to be expected in a switching power supply without any suppression measures.
Buy this device if you want to annoy your shortwave neighbors. Do not buy it dear, if you want to transfer from your current network data (Powerline).
An insulation test 5kV would certainly not survive.
It may be sufficient, on the same network on or off a few fluorescent tubes that wind Ingen SMD capacitors disconnect the USB side of the network, by beating and bears full mains voltage to the USB port.
Instead of actually required capacitors class Y2 namely standard MLCCs are used. Cheap but not permitted for good reason.
The mains supply is internally isolated or insufficiently protected against breakage.
After all, it provides actually as indicated 1000mA power (strictly speaking: 950mA at 4.75V), even for several hours, without heating up excessively, it has other power supplies of its kind ahead.
And there's actually a whole lot worse built copies. One of them has adopted the same day the test after 10 minutes with a loud bang. That came to 1.35 on eBay directly from China.
Conclusion: not everything from the outside looks like the Apple original is also so good. That, incidentally, holds the EMC limits a loose and is perfectly insulated and secure. Where there is nothing to complain about.
Addendum: A whatsoever "overcharge protection" as it says in the description, the device has not.
Can it not, because it provides a power supply just 5V and 1A, so long and so much want the connected device. This could be a great battery overcharge to the final Exitus.
There is a power supply, no charger, as it should have as an overcharge protection. The actual charging technology is in the cell phone. If anything has an overcharge protection, this charge circuit or the battery itself.
This applies to all USB power supplies. Even for Apple.
