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.

Fast Charge:

• 0% to boost in 5 minutes.
• 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.
• Charge up to 5x.

Auto Power Conservation:

• 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.

Spark-Proof:

• 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.

Up to 60W Fast Charging:

• 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 favourite USB-C devices, like phones, tablets, laptops, wearables, and more.

Ultra-Bright:

• 100 LUMENS.
• 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.
