NOCO Boost X is a portable lithium jump starter for 12-Volt batteries in vehicles up to 10.0-Liters gasoline and 8.0-Liter diesel engines, including cars, motorcycles, trucks, ATVs, boats, RVs, vans, SUVs, tractors, and more. 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 in 2.7 hours, or go from 0 Percent to jump starting in just 5-minutes of charge. With Boost X’s 60 Watt USB-C input and output, it is possible to charge up to 5X faster. Use compatible chargers up to 60 Watt 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.
