Generally like this for both its charging capabilities and battery. However, a couple of comments to be aware of.
First, when plugged into a US outlet, the unit is vertical and you can't lay the phone on it to use the wireless charger. If you have plugged it into an extension cord or power strip, you can lay it horizontally to use the wireless charging. However, needing a cord kind of defeats the universal nature of this charger.
Secondly, If you leave the USB cable plugged in, but unplug your phone, the USB charger will shut off after a few seconds. Plugging the phone into the loose end of the cable does not turn the charger back on and you need to either press the power button, unplug and replug the USB cable, or unplug the unit from the wall. As I tend to leave the unit plugged into the wall with the USB cable attached, plugging the phone into the end of the USB cable did not turn the charger on and consequently my phone didn't charge overnight. This is different behavior from other chargers I have used where I can leave the charger plugged in with the cable attached and just connect my phone to the end of the cable and have it charge up.
Don't expect to find any helpful information on the web site that describes this behavior or when to use the on/off switch or the meaning of the red/green pilot light.
