SunPak universal travel adapter convenient but lacking
If you're going to be in an area where they have is grounded outlets, you may be better served finding a grounded adapter to save frustration with improper charging. It’s also a bit limiting with the USB port especially if you need specialty or universal ports for any type of USB2, USB3 or Mini USB. I could see this particular device being handy if you were backpacking for months on end and planning to travel to numerous regions using four or more different types of plugs, otherwise you are better off just bringing individual adapters as they tend to be smaller and lighter.
