Brought it along for a trip to Spain. The USB ports work great. Unfortunately I made the mistake of connecting a small 3 prong extension to it the first night and tripped the breaker. Not sure if this adapter simply can't handle a US plug with a ground, or if it's because the extension had its own surge protector, or if I got a defective unit. I wasn't able to get the fuse door open to check the internal fuse or replace it. I'll check when I'm home.Regardless, I tossed the extension and won't make that mistake again.The plug connection no longer works.Good news is that the 4 USB connections still work beautifully. So that was a plus.
