First, ensure you have turned on the power outlet button and the charging cable isn't loosely connected. Alternatively, use a different power outlet and see if it works.

Why does the Magic Mouse 2 have a charger on the bottom?

I get why Apple decided to place the charging port on the bottom of the mouse. There simply wasn't enough room to place it on the front of the mouse and still maintain the current design. For me, the Magic Mouse has a perfect design; I simply love this thing.
