How many times will a GB50 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. 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.

A rechargeable lithium-powered LED flashlight with seven light modes, including SOS and Emergency Strobe. With multiple luminosity settings, it is immediately adaptable to a variety of situations. Using it's powerful wash light will help you see your engine, help you change a tire at night, or even warn oncoming traffic when you are in need of roadside assistance.

Power for power, this lithium jump starter outperforms traditional lead-acid battery booster packs at a fraction of the size and weight. The heavy-duty battery booster clamps span 23-inches in length, and are capable of reaching most battery posts or chassis ground.
