I had a terrible experience with this adapter, when adapter was connected to power and loaded it with 4A to test it, it simply stopped working after few minutes and my central fuse discovered the power for half of my house, I was lucky I didn't burn my home and no fire came out of it, I would advise you to avoid this product at any cost if you don't want to burn your family, interesting was that Seller tried to do all to make me lose my money, they claimed adapter was tested before it was delivered and that I should pay transport of died adapter back to China with signed letter that costs more than adapter price, terrible shopping experience, good news is, no damage was done to my home or my family
The product works very well.
