Simple.
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. Simply turn on the LED flashlight, recharge a USB device, or use manual override for deeply discharged batteries.
More power, a fraction of the size.
Compared to an equivalent 1,850-amp lead-acid jump starter, the GB70 provides 15,700 joules versus 6,950 joules. Not only is it 2X more powerful, it's nearly 4X smaller and lighter.
Joules, not peaks amps.
Joules start vehicles, not peak amps. The average vehicle jump starts in 1-3 seconds, making peak amps somewhat worthless. But actual power over time illustrates a battery booster's real potential.
Jump starts per charge.
A powerful lithium jump starter capable of jump starting up to 40 vehicles on a single charge. It's rated for over 1,000 charge cycles and holds its charge level for over a year with minimal power loss.
Multi-function jump starter.
Jump start cars, boats, RVs, and trucks, as well as diesel pickups, hot rods, classic cars and more. Even recharge USB devices, like a smartphone, and power 12V devices, like a tire inflator.
Rapid recharge.
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.
Portable Power.
Power 12V tire inflators, power inverters and more.
It's more than just battery jump starter pack, it is 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.
Ultra-bright.
400-lumen 8X LED flashlight.
A rechargeable lithium-powered LED flashlight with seven light modes, including SOS and Emergency Strobe. With multiple luminosity settings, it's 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.
Portable, hand-held design.
Incredible power in a compact-sized jump box.
Power for power, this lithium jump starter outperforms traditional lead-acid battery booster packs at a fraction of the size and weight. It's nearly 4X lighter, and its lithium-powered design makes it more compact and portable than ever before. Conveniently store in a center console, trunk, or toolbox.
