- Compact and portable, easily stored in a glove box or backpack.
- High peak current starts large engines quickly and reliably.
- Built-in power bank and flashlight add emergency utility beyond jump starting.
- Rugged build with IP65 rating withstands harsh conditions and rough handling.
Cons
- Battery charge may drain over several months if unused, requiring periodic recharging.

The NOCO Boost GB50 is a compact, 1500-amp lithium jump starter designed for drivers who want a reliable, safe, and portable solution for dead 12V batteries. It is ideal for cars, trucks, SUVs, motorcycles, ATVs, boats, and more, with support for gas engines up to 7.0 liters and diesel up to 4.5 liters. Whether you are a daily commuter, weekend adventurer, or someone who wants emergency preparedness, this jump starter delivers peace of mind on the road.
Standout features include UltraSafe Technology, which eliminates sparks and prevents reverse polarity, making it virtually foolproof even for those unfamiliar with jump starting. Real-world performance is exceptional, with users reporting instant starts and up to 30 jumps per charge. The integrated USB-C power bank and 200-lumen LED flashlight with seven modes add versatility, allowing you to charge devices or signal for help in low-light conditions.
Build quality is impressive, with a rugged IP65-rated enclosure that resists water, dust, and impacts. The rubberized over-molding and compact 2.7-pound design make it easy to store in a glove box or emergency kit. Included accessories like heavy-duty clamps and a microfiber bag reflect NOCO's attention to detail. However, the battery will self-discharge over several months if not recharged, and the USB-C charging cable requires a separate wall adapter.
A minor drawback is that the 1500-amp peak may not suffice for larger diesel engines above 4.5 liters, but it handles most consumer vehicles admirably. Some users might also prefer a built-in AC outlet, but the compact form factor is a trade-off for portability. Overall, the GB50 is a top-tier choice for its safety, reliability, and multi-functionality.
Verdict: The NOCO Boost GB50 is an excellent investment for anyone seeking a safe, powerful, and portable jump starter. Its UltraSafe technology, compact design, and additional features like a power bank and flashlight make it a standout in the market. If you want a dependable solution for roadside emergencies, this is a smart buy.
Buying Guide: How to Choose the Best NOCO Jump Starter
Power and Peak Amps
The most critical factor is how many peak amps a jump starter delivers. This determines which engines it can start. For a small car or motorcycle, 500 amps (like the NOCO Boost GB20) may suffice. For larger gas engines up to 8.0 liters or diesel engines up to 6.0 liters, you need a model with 1500 to 2000 amps, such as the NOCO Boost GB50 or the NOCO Boost Air AX65. Always consider the engine size of your vehicles before choosing.
Peak amp ratings are often overstated, but NOCO’s numbers are verified through independent reviews. The higher the amp rating, the more starts you get per charge and the more reserve power you have for emergencies. If you own multiple vehicles or a large SUV, invest in a higher-capacity model.
Safety Features
Jump starting a battery can be dangerous if you reverse the polarity or create sparks. NOCO’s UltraSafe technology, including spark-proof and reverse polarity protection, makes connections foolproof. All models in this review have this safety net, but the GBX55 and AX65 feature the latest UltraSafe 2.0 with enhanced thermal management. This is especially important if you are new to jump starting or work in tight engine bays.
Portability and Build Quality
Jump starters should be compact enough to stow in a glove box or under a seat, yet rugged enough to withstand drops and weather. The NOCO Boost GB40 weighs just 2.5 pounds and fits in most compartments, while the GBX55 and GB50 have IP65-rated housings that resist water and dust. If you often drive off-road or in harsh conditions, prioritize a model with robust build quality. For added versatility, consider pairing your jump starter with a best 12V tire inflator to handle both flat tires and dead batteries.
Additional Features
Modern jump starters double as power banks and LED flashlights. The NOCO Boost Air AX65 goes a step further by integrating an ultra-fast air compressor capable of inflating tires from 0 to 40 PSI in 2 minutes. This all-in-one device is ideal for long road trips. Other models like the GBX55 and GB50 have USB-C Power Delivery to charge laptops and phones quickly. Consider which extra features matter most to you—whether it is a built-in inflator, high-lumen flashlight, or fast recharge times. A best rechargeable tire inflator can also be a standalone tool if you prefer separate devices.
Final Thoughts
After evaluating the lineup, we believe the NOCO Boost GBX55 1750A UltraSafe Jump Starter is the best overall choice for most drivers due to its extreme power, fast USB-C charging, and compact design. For those who want a complete roadside kit, the NOCO Boost Air AX65 2000A 12V Jump Starter combines jump starting with an ultra-fast tire inflator and high-capacity power bank, making it a versatile companion for any trip. Both models deliver NOCO’s proven reliability and safety, so you can hit the road with confidence.
