Introducing a new kind of jump starting experience featuring our latest PX Lithium Technology that delivers incredible power, ultra-fast charging, and unmatched versatility. This isn't an upgrade— it's a whole new series. The new Boost X offers more starting power and unleashes maximum power delivery for the most demanding starts. Paired with USB-C Power Delivery technology to recharge insanely fast.

Boost X is now turbo-chargeable. It is equipped with USB-C technology that, combined with power delivery, gives you lightning-fast recharges. Completely recharge the GBX45 in 48-minutes, or go from 0% to jump starting in just 5-minutes of charge. With Boost X’s 60W USB-C input and output, it is possible to charge up to 5X faster. Use compatible chargers up to 60W to increase your charging speed.

Start the vehicle within 60 seconds after pressing the power button on Boost. After the 60-second timeout is complete, the unit must be powered off, then back on, to initiate a new jump-start sequence. The yellow power LED indicates the 60-second sequence is over and can be reset if another jump start sequence is needed.

We took our UltraSafe technology and made it better— UltraSafe 2.0. It's still our simple, mistake-free design featuring spark-proof technology and reverse polarity protection, but with enhanced thermal efficiency and power management to provide better performance and longer battery life.

Power everything. With USB-C Power Delivery, you have the power to charge almost everything. Its internal power bank provides 60-watts of power— both in and out— to effortlessly power our favorite USB-C devices, like phones, tablets, laptops, wearables, and more.

More than a jump starter, Boost X is a useful tool for daily use and emergency situations alike. The GBX45 is equipped with a 100-Lumen LED flashlight with various brightness modes, SOS, and emergency strobe— handy to have as a roadside or road trip tool.
