Boost Max Overview

Boost Max Overview

The Boost Max Series - Introducing our most powerful lithium jump starters yet. Designed for the largest, most challenging engine starts ever. It's commercial in every way. It jump starts almost every type of vehicle and equipment, including semi-trucks, motorhomes, coaches, buses, mining, agricultural, construction, and vocational equipment.
  • - 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.
  • - Integrated Voltmeter / 60 Second Countdown Timer. The Boost MAX GB500+ is equipped with an integrated voltmeter to help pinpoint battery issues. The voltmeter doubles as a 60-second countdown timer, which shuts off GB500+ after 60 seconds to help preserve internal battery charge.
  • 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.
  • 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 lithium-ion battery in 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. (GB251+: 600 Lumens, GB500+: 2200 Lumens)
