APC 6000mAh Mobile Power Pack

The black 6000mAh Mobile Power Pack from APC is a portable lithium-ion polymer battery pack that supports Qualcomm Quick Charge. You can charge two USB devices simultaneously using its two USB Type-A ports, which output a total of 5V/3.4A. One of the USB ports outputs 5V/2.4A, while the Quick Charge port can output either 9V/1.5A or 12V/1.5A to supported devices. Otherwise, it outputs 5V/1A. When the battery is depleted, it can be recharged using its 5V/2A micro-USB input, and recharging takes around 4 hours. Thanks to pass-through charging, this power pack can charge external devices while it is charging.
