The Verbatim Dual USB Pack (8400mAh) is designed to provide emergency on-the-go power for smartphones, e-readers, portable music players, Bluetooth wireless headsets and other portable electronic devices. Since it's equipped with two USB ports, you can charge two devices at once.
The generous 8400mAh capacity of the power pack allows it to provide enough power for many different devices. For example, it can add up to 75% charge on an iPad 1st or 2nd Gen, or charge an iPhone 4S/5 up to 4.5 times. To recharge the power pack, simply use the included USB cable. You can also use it to charge your micro USB-powered devices. The power pack features a push-on/auto-off button that switches on the charger. Additionally, an LED power status indicator gauges how much charge is available.
