Review on Magnadyne WC-USB-B 12V Wall-Mounted USB Charging Station with 4 Ports, Universal 12-16V DC Input, and Included Wall Plate by Ross Bagby

Connected to 12V with mains fuse. Worked fine yesterday. This morning we found that none of the connected devices were working and the cables were no longer carrying power. That outlet blew our system and our POS card reader has no screen and our Apple cables don't charge the devices either. WTF We have a mobile store and now we don't have a working POS credit card reader, everything is manual now and we have to buy new cables to charge our scanner, iPad and mobile phones. Battery power to fuse box. OK, but the USB wall mount doesn't work. Therefore, something in it is shorted out, and everything that was connected at the time of the short circuit no longer works. I'm angry, to put it politely. This box fried over $150 worth of electronics!
