Wireless charger side this unit to recharge all compatible devices with wireless charging technology, the charging speed is slower than that of industry, but still reasonable. the unit will beep to indicate that your device is charging. The plastic surface and the rubber logo allow the phone does not slip
Side battery, it can charge the compatible devices with wireless charging technology and also the other via USB (it can even charge 2 devices simultaneously!)
Its 4800mAh capacity is more than sufficient to charge most phones (it could recharge a fully Nexus 5 2 times)
In short, it's a great versatile product that I recommend!
