The Trust PW-2770p 230V Car Power Socket Dual voltage converter I tested three weeks Norway. The loading of laptops (MacBook Pro 15 "), photo-cams etc. The heat development must be assessed as rather small, as opened by the upright position in the cup holder in the heat a good "way out". The emergency shutdown at low voltage I tested, involuntarily. On the ferry, the device has obediently turned off and the car (diesel engine) has started properly.
