When going to different countries, the charging conventions can be a pain. I used to have a travel adapter that let me charge my gadgets anywhere. However, it just let me charge a single gadget at a time, which was tedious.
I recently switched to the A-Clever Travel Adapter and this solves all my pain points.
a) Doesn't have to be disassembled to fit different plug points. Just have to press buttons and slide things around
b) Has female USB charging ports. Can use this to charge my phones/tablets and leave the main adapter for the laptop
c) Used Qualcomm Quick Charge 3.0 so my supported gadgets (like my Android smartphone) now charge a whole lot quicker, as if I was using their stock charger.
