Multi-port charging

For those of us who have apple everything, we know that keeping everything charged at the same time is quite an effort. So, companies have created multi-port chargers, and I was lucky enough to receive two for Christmas; one from my father, and one from my maternal grandmother, and I though that I would make a few observation that would enable me to return the correct item.

Grandma got me an Anker 5 port wall charger. 40w, all usb, $25.99.
Dad got me a TechMatte 5 port wall charger 50w, all usb, $20.99

So, from what I am able to safely deduce, with the techmatte charger, there are ten more watts for five less dollars.

The choice was obvious. Sorry grandma
