Of course, if you are really looking for the absolute fastest battery charge...this is it

Wireless requires turning on battery before charging, making it slower than plugging in USBNo way to line up phone easily to align wireless charging (I learned where to set my Note on it)Overall it is a pretty nice battery with a reasonable capacity.

I always said I wish iPhones allowed you to buy extra batteries for it like the Star Tac used to (long time ago)

So this battery is pretty awesome with all of its perks.

This wireless battery is great

First it's a good size battery that'll allow you to charge more than one thing at a time--though you'll have to choose which port to use, since one sends a bigger charge than the other

The edges are rounded and curved making it easy to hold and the display gives a clear readout of your available battery power

Battery is slick.

So, I thought to myself that it would be best to try to kill two birds with one stone and attempt to find a portable battery pack that also did wireless charging

These are minor issues for most and I would still recommend this back up battery.

As is usual, there is no "real" equivalent on the iPhone X, but it also appeared to charge on this port as fast as I could expect
