A step above the RTS adapter is the Cable World universal adapter. It includes dual USB ports capable of supplying current up to 1A 10W. Other than that, it’s capable of accepting plugs from up to 150 countries including China, Singapore, Dubai, France, Switzerland, etc.
This one too comes with a built-in surge protector and safety shutters and supports a variety of devices like phones, laptops, cameras, etc.
A tad up the ladder is the VCoo travel adapter. This isn’t an Indian product, so you might have to shell out extra bucks for this one. It includes two USB ports for charging smartphones and music players.
Similar to most of the adapters, it also comes with a built-in fuse protection and safety shutters. However, it can’t support appliances over 1300 watts. So it won’t work on hair dryers or iron.
