Everything you need on one interface.
We designed the user interface to be simple and easy to understand. LED status indicators display the internal lithium batteries charge level and charging status. Error indicators show when connected in reverse polarity or temporarily disabled for thermal protection. Or simply turn on the LED flashlight, recharge a USB device, or use manual override for deeply discharged batteries.
Needle-nosed battery booster clamps.
Perfect for hard-to-reach battery applications.
Designed for connecting to batteries with restricted access to the battery terminals, like a motorcycle. The needle-nosed battery clamps feature an integrated eyelet connector that detaches and allows for permanent battery installation for plug-n-play jump starting.
Stay charged. Power your USB devices on the go.
How many times will a GB20 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.
