Unmatched versatility. An all new BOOST MAX series.

Introducing a new kind of jump starting experience featuring our latest PX Lithium Technology that delivers incredible power, ultra-fast charging, and unmatched versatility. This isn't an upgrade— it's a whole new series. The new Boost MAX offers more starting power and unleashes maximum power delivery for the most demanding starts. The Noco GB251+ Noco Boost MAX is an extremely powerful power bank and also a starter booster. With the start booster function, it can even start diesel engines up to 32 liters in size. And when the GB251+ is fully charged, it can do that 6 to 10 times. Note: a starting aid is always a 'help'. The jump starter/booster helps the existing battery in the vehicle to start. If the battery is really completely empty, the vehicle may not be started even with a booster. In such a situation, a heavier to very heavy jump starter is required to start the vehicle or it may be necessary to briefly charge the battery first. This loading cannot be done with the GB251+.

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. Always connect a starter booster directly to the poles of a battery/battery and never via any other (thinner) cabling in the vehicle. This is very important to prevent high starting currents from damaging the cabling in your vehicle. Always connect the red plus terminal to your battery first and then the black minus terminal or the chassis of the vehicle (not in a place on or near the paintwork of your vehicle). Disconnecting the starter booster is done in reverse order. Starting your vehicle is done as follows: Connect the battery terminals as described above. Turn off as many power consumers as possible, such as lighting, radio or air conditioning. Then press the power button on your booster. All LEDs will flash once and then the Boost LED will light up. When the Boost LED lights up, you can start the vehicle.

Reverse polarity protection

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. The GB251+ from Noco is non-sparking and protected against incorrect connection of the battery terminals (reverse polarity or polarity reversal) and overheating. Furthermore, the GB251+ will not automatically start a vehicle if the battery voltage is 4V or lower. The boost LED will not illuminate and you will need to switch to manual start boost mode. This is an important built-in safety so that a starting boost is not given if the booster is not connected to a battery or if you do not want it.

Charge & recharge. USB & 12V power.

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 133 watt-hours lithium-ion battery in 8.5 hours. The output of the jump starter is as follows: Starting capacity: 24V / 3000A max; USB-A output: 5V 2.1A - 10W Max (for phones and tablets);  12V output: 12V 15A (max). There is no 24V output. Note: 12V or 24V batteries cannot be charged with the Genius GB251+. 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 133 watt-hours of lithium power, the GB251+ can provide endless hours of operation and recharge your devices multiple times before needing a recharge. Because the Noco Boost MAX is equipped with an internal lithium battery, it is a maintenance-free starter booster. That is certainly not to say that you should not load the starter booster once in a while. The advice is therefore to ensure that you always fully charge your starter booster at least once every 2 months.

High lumen LED flashlight.

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. On one side of the GB251+ are powerful white LED lights that can light up or flash in 6 different modes (600 lumens). They can be used to shine in the dark under the hood or near the battery. They can also be used as SOS light or emergency signal lighting. This LED lighting can also be used as a powerful flashlight. Having a powerful flashlight with you can always come in handy.

Integrated voltmeter. Understand the problem.

Integrated Voltmeter / 60 Second Countdown Timer. The Boost MAX GB251+ 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.
