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 266 watt-hours of lithium power, the GB500 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 266 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 GB500+ is equipped with a 2,200-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 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.
