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.

Buying Guide: What to Look for in a Lithium Jump Starter
Peak Amperage and Engine Compatibility
The most critical spec is peak amperage, which determines how easily the unit can crank a dead battery. For a standard gasoline engine up to 4.0 liters, 500 amps is usually enough. For larger V8s or diesel engines, you want at least 1000 to 1500 amps. The TREKURE model delivers an impressive 8000 amps, making it suitable for massive 12.0L diesel engines. Meanwhile, the NOCO GB50 offers 1500 amps for engines up to 7.0L gas or 4.5L diesel. Choose based on your vehicle size and the worst conditions you might face.
Safety Protections and Build Quality
A jump starter that sparks or reverses polarity can damage your car or cause injury. Look for units with spark-proof technology and reverse polarity protection. NOCO’s UltraSafe system is a standout, with patented circuitry that prevents connection errors. The TREKURE model includes ten intelligent protections plus V-0 flame-retardant materials. A rugged, weather-resistant shell (like IP65 rating) adds durability for roadside use. For more smart upgrades, see our list of best car gadgets on Amazon.
Portability and Extra Features
You want a jump starter that fits in your glove box or travel bag without weighing you down. The NOCO GB20 weighs only 2.4 pounds and is about the size of a tablet. The GB50 is slightly heavier at 2.7 pounds but still compact. The TREKURE unit is 18 percent smaller than traditional models and includes a built-in handle. All three double as power banks for charging phones and tablets. Integrated LED flashlights with SOS and strobe modes are invaluable during nighttime emergencies.

Ease of Use and Maintenance
The best lithium jump starter is one you can operate without a manual. Simple three-step connections (power on, attach clamps to unit, then to battery) reduce confusion. Look for clear indicator lights and audible alerts that confirm correct hookup. Long standby time matters too: the TREKURE holds a charge for up to 24 months, while the NOCO models recharge in 3 to 5 hours.
