Glad to hear that phones and computers are ok. I would hate to fry them!
Our room clock ran slow this past trip also. We had a CD player fry 3 years ago on the first night. I was able to change the square box on the cord and now it works again. Only thing I know about AC current is DONT MESS WITH IT LOL.
Our electric clock would always run slow and lose time. We now pack a battery operated one...so nice to know what time it is if I wake up during the night. I also ALWAYS use a surge protector when the laptop is plugged in. No problems.
