I bought the voltage converter for my camper. For the charging of my PC, mobile and accus for my camera everything works great. The device hardly heats up. My current voltage converter 150 Watt was very hot and has given up the ghost. I have my hairdryer 1200Watt connected, but to no avail; the converter switched off immediately. Did not matter just a test and for me. Price and achievement are correct. Definitely 5 star.
