The voltage transformer has done exactly what I expected from him. A dispenser connected battery of 50 Ah and he has endured a hair dryer. Level 1 (600 W) without problems 25 minutes and level 2 (1260 W) for 5 minutes, however, with a warning. The battery power has decreased after this time only by a third. The product I can only recommend. I need this for the caravans in Norway because as the campsites are represented fortunately not so lush.
