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.
8X smaller and lighter.
Compact, pocket-sized lithium jump starter that fits perfectly in your glove box. It is 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.
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 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.
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 8X smaller and 8X lighter, and its lithium-powered design makes it more compact and portable than ever before. Conveniently store in a glove compartment, center console, trunk, or toolbox.
The heavy-duty battery booster clamps span 23-inches in length, and are capable of reaching most battery posts or chassis ground. It features a high-temperature silicone wire insulation that remains extremely flexible down to -40-degrees centigrade, withstands high levels of duress, and even withstands prolonged exposure to high temperatures.
