BOOST 12V 2000A JUMP STARTER

Massive Power

5250A 

Introducing the most powerful lithium jump starters from NOCO yet. Designed for the largest, most challenging engine starts ever. With over 5250-amps of starting power, it can jump start gasoline and diesel engines up to 16-liters. It's commercial in every way. It jump starts almost every type of vehicle and equipment, including semi-trucks (up to class 8), motorhomes, coaches, buses, mining, agricultural, construction, and vocational equipment - 6, 8, 12, and 16 cylinder - and more.

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

Ultra Safe 2.0

Noco took Spark Proof technology and made it better. UltraSafe 2.0. It's still 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.

USB Charging
With two built-in 2.1A USB ports, you can power multiple devices at the same time, such as smartphones, tablets, action cameras, wireless headphones, wearables and more. With over 242 watt-hours of lithium power, the GB250+ can provide endless hours of operation and recharge your devices multiple times before needing a recharge.

Rapid Recharge

From 0-100% 4X Faster. Charge directly from the vehicle's 12-volt auxiliary port or the XGC4 4-Amp Power Adapter to recharge it’s 242 watt-hours lithium-ion battery in 8.5 hours.

Integrated Voltmeter / 60 Second Countdown Timer

The Boost MAX GB250+ is equipped with an integrated voltmeter to help pinpoint battery issues. The voltmeter doubles as a 60-second countdown timer, which shuts off GB250+ after 60 seconds to help preserve internal battery charge.

High-Lumen Flashlight

More than a jump starter, Boost MAX is a useful tool for daily use and emergency situations alike. The GB250+ is equipped with a 600-Lumen LED flashlight with various brightness modes, SOS, and emergency strobe— handy to have as a roadside or road trip tool.

Compact & Lightweight

Jump starters this powerful typically are enormous and weigh hundreds of pounds, but our high discharge lithium technology makes it the most compact and lightweight design in the world - weighing a mere 15-pounds. And its portable carrying case makes jump starting more convenient than ever.
