Now you can conveniently charge your Nexus 4, Nexus 5, Nexus 6, or Nexus 7 without plugging a cable into your device. All of these devices have built-in wireless charging capability. The only thing you need is a Nexus Wireless Charger or any Qi wireless charger.
The straight face Nexus wireless charger is specifically designed to magnetically latch onto the Nexus phones and Tabs and instantaneously begin charging.
Just plug your wireless charger with a power outlet by using the power adapter provided and place the device on it.
Make sure that the top surface of the charger is free of metal objects (like coins or keys) as they’ll interfere with charging.
The device and the charging pad may become warm with the normal use, but take it easy! No worries!
