How many times will a GB40 recharge my device?
The built in 2.1A USB out port can power all of your USB devices, such as smartphones, GoPro cameras, wireless headphones, and more. The battery capacity inside of your iPhone, for example, is measured in “milliamp-hours,” or mAh—a way of measuring how long the device will last. Devices that are frequently being used, like phones and cameras, often require more power to run all day than the device’s battery is rated for. Boost’s battery pack extends the life and running time of your device. Plus, powering your device from an external battery pack will reduce the internal battery’s charge cycles, extending the usable life.
