That’s exactly the one I used in the Philippines (and many other countries), it’s a Swiss brand with excellent built quality and overcharge protection, unlike many of the no name China things you find on Amazon. It’s compatible with all plug types from A through G, and with the 2 USB sockets you can actually charge 3 devices at once.
For the devices you listed, no transformer is needed, correct.
Hair dryers are btw. the most common single-voltage appliances that cause issues, so don’t bring one of those…
