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.
Recharge 3X faster with XGC
The GB70 is completely rechargeable from any USB-powered port, like a wall charger, car charger or laptop. But it takes 7-hours. With XGC, you can charge directly from the vehicle’s 12-volt auxiliary port and utilize its rapid charge technology to recharge 3X faster – just over 2 hours. Go from zero charge to jump starting in just 15 minutes.
Power 12V tire inflators, power inverters and more
It’s more than just battery jump starter pack, it’s portable 12-volt power. Go anywhere and power your favorite 12-volt devices, like a tire inflator, power inverter, coffee maker, fan and much more.
Stay charged. Power your USB devices on the go
How many times will a GB70 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.
