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. Or simply turn on the LED flashlight, recharge a USB device, or use manual override for deeply discharged batteries.
8X smaller and lighter
Compact, pocket-sized lithium jump starter that fits perfectly in your glove box. It’s eight times smaller and lighter than traditional battery booster packs.
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 boosters real potential.
Jump starts per charge
A powerful lithium jump starter capable of jump starting up to 20 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, pickups, hot rods, classic cars and more. Even recharge USB devices, like a smartphone, tablet and much more.
Stay charged. Power your USB devices on the go
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.
Ultra-bright
100-lumen dual 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. Use it’s powerful wash light will help you see your engine, changing a tire at night or even warn oncoming traffic when disabled and needing of roadside assistance.
Portable, hand-held design
Incredible power in a pocket-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 over 10X smaller and 8X lighter, and its lithium-powered design makes it more compact and portable than ever before. Conveniently stores in a glove compartment, center console, trunk, or toolbox.
Measurements
Spans 23-inches
The heavy-duty battery booster clamps span 23-inches in length, and capable of reaching most battery posts or chassis ground. It features a high-temperature silicone wire insulation that remains extremely flexible down to -40-degress centigrade and withstands high levels of duress and even prolonged exposure to high temperatures.
