5250 Amp UltraSafe Lithium Jump Starter
The GB250+ is a 5250-amp portable lithium jump starter for gasoline and diesel engines up to 16-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.
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 GB250+ 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 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.
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.
