No more frantic searching for an AC power outlet when your mobile device's battery power is getting low. The high-capacity UPB-10K4-S2U 10,400mAh Dual-Port Mobile Power Bank is an ideal power solution when you're on the road or stuck somewhere without convenient electricity. The portable dual-USB battery charger weighs barely half a pound, and fits comfortably in your purse or backpack to keep your phone, tablet, e-reader, MP3 player, digital camera or other handheld device operating when you need it.

Just connect your devices to the UPB-10K4-S2U's USB-A ports using the included USB Micro-B cable and/or another cable suitable for your device. The devices will begin charging immediately. Press the on/off button to monitor the power bank's battery capacity via the easy-to-read LEDs and know how much charge is available.

The dual USB ports provide up to 5V 1A and 5V 2.4A of power, respectively, so you can charge two devices at once. In addition, the 2.4A port benefits from auto-sensing technology that identifies how much amperage the connected device is designed to take and adjusts its charging accordingly.

The lithium-ion battery's hearty 10,400mAh capacity charges devices at maximum power draw for hours. It protects against short circuits, overvoltage, overcurrent, overcharges and overdischarges for safe, reliable charging. To charge the UPB-10K4-S2U, connect the USB Micro-B port to a USB charger or a computer's USB port using the included cable.
