For items that don't require alot of juice like my wife's hair straightener, this is a great adapter. we used this daily to charge a variety of different electrons including her Thinkpad laptop, a Nintendo Switch, Amazon Fire Kindle, iPad mini, a small video camera used to record webinars, and both our cell phones. No items were damage by the different voltage and the adapter never overloaded when charging multiple items at once. It is even useful at home in the states if you're on the go and need an adapter with several USB ports at once
