Charge on the go, with the Samsung 2,100mAh Battery Pack mini. With a universal USB port output, you can charge smartphones or other electronics capable of charging via USB. The battery pack comes with an included USB - Micro USB cable for charging a mobile device from the battery or charging the battery via a USB charging source (not included). The battery pack’s 2,100mAh capacity can be recharged over and over. When fully powered, the battery pack holds enough juice to provide up to half a charge for most smartphones.
To begin charging, plug in a USB charging cable like the included USB - Micro USB charging cable to the USB output port (larger rectangular port) on the battery pack and connect the opposite end of your charging cable (whether Micro USB or other) to your smartphone or other electronic device. Your device will immediately begin to charge. For recharging the battery pack itself, plug a Micro USB charger into the Micro USB port of the battery pack.
Official Samsung lithium ion batteries are built-in to ensure an optimal charging experience for a range of Samsung or non-Samsung devices.
The 2,100mAh Battery Pack mini hosts an LED indicator that displays remaining charge when the status button next to the light is pressed. The LED also lights up when the battery pack is charging and blinks to indicate how close the battery is to being fully charged.
