The NOCO Boost GB40 is a premium portable jump starter designed for any driver who wants reliable emergency power without the hassle of traditional jumper cables. Whether you drive a sedan, truck, motorcycle, or RV, this compact lithium powerhouse delivers 1000 amps of peak starting power in a package that weighs just 2.5 pounds. It's perfect for those who park multiple vehicles, drive older cars prone to dead batteries, or want genuine peace of mind during long road trips.
Performance is where the GB40 truly shines. The lithium technology provides consistent, reliable starts on gasoline engines up to 6.0 liters and diesel engines up to 3.0 liters. Real-world users report that the device works even when charged to a single bar, and most vehicles start in under a minute. The UltraSafe Technology featuring spark-proof connections and reverse polarity protection eliminates the anxiety of making a wrong connection, making it foolproof for anyone to use.
Beyond jump starting, the GB40 functions as a USB-C power bank for smartphones and tablets, includes a precision 100-lumen LED flashlight with seven modes for roadside emergencies, and recharges fully in just three hours. The rugged IP65-rated housing with rubberized casing withstands water, dust, extreme temperatures, and impacts, making it genuinely built for outdoor and off-grid adventures.
The main limitation is battery self-discharge during storage. Users who keep the GB40 in a trunk for rare emergencies report it drains over time, requiring occasional recharges to maintain full readiness. Additionally, the LED flashlight lacks an on-off lock, so accidental activation can deplete the battery. These are minor trade-offs for the overall convenience and reliability this device provides.
The NOCO Boost GB40 represents excellent value for emergency automotive power. It's reliable when you need it most, compact enough to forget you own it, and versatile enough to serve multiple purposes. For drivers who value dependability, portability, and peace of mind, this is a worthwhile investment that pays for itself the first time you avoid calling for roadside assistance.

When to Use It: Use the GB40 whenever your vehicle battery dies unexpectedly. Keep it charged in your glove box or trunk for emergencies. The power bank function makes it useful for charging devices during road trips or outdoor adventures. The LED flashlight provides emergency illumination during nighttime roadside situations.
Maintenance Tips: Check the charge level every 1-2 months if storing long-term, as the battery naturally self-discharges. Recharge to 100% before storing for extended periods. Avoid leaving the LED flashlight accidentally activated. Keep the device in the included microfiber storage bag to protect from dust and impact.
Comparison Consideration: At this price point, the GB40 offers superior reliability and build quality compared to basic jump starters. The addition of a power bank and LED flashlight provides genuine utility beyond jump starting. If you only need occasional emergency starts, a basic model might suffice, but the GB40 justifies its cost through durability and multi-purpose functionality.

Buying Guide: What to Look for in a Jump Starter for Your SUV
Peak Amps: Matching Power to Engine Size
SUVs often have larger engines, especially if you drive a diesel model. Peak amps indicate the maximum power the jump starter can deliver in a short burst. For a standard gas SUV up to 6.0L, 1000 to 2000 peak amps may suffice, but for larger engines or cold weather starts, consider models with 3000 to 6000 peak amps. The products we evaluated range from 1000A to 6000A, so there is an option for every engine size.
Battery Capacity: More Jumps, Less Worry
The battery capacity, measured in watt-hours (Wh) or amp-hours (Ah), determines how many jump starts you get per charge. A higher capacity, like the 88.8Wh in some models, can provide multiple starts and also serve as a power bank for devices. If you frequently help others or drive long distances, a larger capacity is a smart investment.
Safety Protections: Spark-Proof and Reverse Polarity
Jump starting a battery involves risk if connections are wrong. Look for features like spark-proof technology and reverse polarity protection. Many modern jump starters have smart clamps that prevent damage and beep when connected incorrectly. We prioritized models with multiple safety certifications and protections.
Extra Features: LED Light, Power Bank, and Air Compressor
Some jump starters double as emergency lights, USB power banks, or even tire inflators. For SUV owners, a built-in air compressor can be a lifesaver for topping off tires after a trail. Consider which extras align with your typical use. For example, the GOOLOO A3 includes an air compressor, making it a versatile tool for roadside emergencies.

Frequently Asked Questions
Can I use a jump starter on a diesel SUV?
Yes, but you need a model with sufficient peak amps. Diesel engines require higher cranking amps than gasoline. Look for jump starters rated for diesel engines, such as the OXILAM 6000A or the WOLFBOX 4000A. For diagnosing starting issues, consider reading our best scanner for Powerstroke guide.
How many times can I jump start my SUV with one charge?
It depends on the battery capacity. For example, the NOCO Boost GB40 can provide up to 20 starts on a single charge for engines up to 6.0L gas. Larger capacity units like the WOLFBOX may offer more starts. Always recharge the jump starter after each use to keep it ready.
Is it safe to leave a jump starter in my SUV during extreme temperatures?
Most modern jump starters are built to withstand temperatures from around -4°F to 140°F. However, extreme heat or cold can affect battery life. Store it in the cabin rather than the trunk if you live in very hot climates. The models we reviewed have rugged housings rated for these conditions.
Do I need a jump starter with an air compressor?
It is a convenient feature if you often deal with low tire pressure. The GOOLOO A3 combines jump starting and tire inflation in one unit, saving space. If you already carry a separate compressor, a dedicated jump starter may be lighter and more portable.
