NOCO GB251 3000A 24V UltraSafe Lithium Jump Starter

The GB251+ is a 3000-amp portable lithium jump starter for gasoline and diesel engines up to 32-liters, including semi-trucks (up to class 8), motorhomes, coaches, buses, mining, agricultural, construction, and vocational equipment - 6, 8, 12, and 16 cylinder - and more.

 

Introducing our most powerful lithium jump starters yet. Designed for the largest, most challenging engine starts ever. With over 3000-amps of starting power, it can jump start gasoline and diesel engines up to 32-liters.

 

Safe and easy to use battery jump starter pack without the worry of incorrect connections or sparks. Safely connect to any 24-volt battery with our mistake-proof design featuring spark-proof technology and reverse polarity protection.

 

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. Plus, an integrated digital battery voltmeter for enhanced diagnostics.

 

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 14-pounds. And its portable carrying case makes jump starting more convenient than ever.

 

It's not just a lithium jump starter but also a portable power bank for recharging smartphones, tablets, and other USB devices, with an ultra-bright 600-lumen LED flashlight with seven light modes, including emergency strobe and SOS.

 

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.

 

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.

 

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 137 watt-hours of lithium power, the GB251+ can provide endless hours of operation and recharge your devices multiple times before needing a 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 137 watt-hours lithium-ion battery in 8.5 hours.

 

More than a jump starter, Boost MAX is a useful tool for daily use and emergency situations alike. The GB251+ 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.

 

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 GB251+ after 60 seconds to help preserve internal battery charge.
