BEWARE !
This spring (2016), Dutch authorities have tested 230V USB chargers for electronic devices like iPhones and iPads. And the results are alarming : of the 41 chargers tested, 10 have tested ‘high risk of fire, explosion and injury’ (most of these were cheap unbranded USB-chargers) and another 14 have tested ‘dangerous because of missing safety documentation’ (these even included USB-chargers by Sony, Samsung, Huawei and Nokia). All these 24 USB-chargers have been banned from the Dutch market immediately, and selling these is now prohibited.
PLEASE BEWARE !
As you may already have purchased one of these dangerous USB-chargers, be sure to check the list below and compare with the USB-chargers within your household. If you find one, stop using it immediately !
The full list [with pictures] of USB-chargers tested can be found here (Google-translated into English) :
GREEN label = tested okay (no safety risk)
YELLOW label = dangerous because of missing documentation (safety risk)
RED label = hazardous (high safety risk)
