The set I bought for use in mounting car. The decisive factor here was the right long USB charging cable (5). The connector now hold almost 4 weeks and there are no signs of wear visible (5). The car charger adapter charges my phone reliably and completely (5). The car power supply has stable contact and firmly seated in the car jack (5). The 230V power supply, however, hums questionable (0) and manages to not even my wireless mouse fully charge (0). Fear the house could burn if you leave it unattended has compelled me throw it away (0). The manufacturer would do well to the 230V power supply did not deliver until, because it harms the overall product more. Average rating 2.85 star but because I have the set actually ordered only for the car 4 stars.
