Product as advertised, did not test fully yet.
Very fast delivery to Poland - took 2 weeks. I had no need to contact with the seller. Has short circuit protection. Cable is rated only 24AWG but gives 2 Amps when charging. When idle gives stable 8.4 Volts. Does not generate too much heat. Cable length is 85 cm . The LED turns from red to green when current drops to 225 mA and charging still goes by.
