8 Best NOCO Jumper Starters of 2025

The NOCO Boost GB50 is a game-changer for drivers who want serious starting power without breaking the bank. With 1500 amps of peak current, it confidently handles gas engines up to 7.0L and diesel up to 4.5L—making it one of the most capable budget jump starters on the market. Its patented UltraSafe technology eliminates the fear of sparks or reverse connections, a lifesaver for first-time users or those working in stressful roadside situations. Compact at just 2.7 lbs, it slips easily into a glove box, yet packs enough juice for up to 30 engine starts on a single charge.

In real-world testing, the GB50 consistently fired up cold V6 and smaller V8 engines, even after multiple failed cranks. The integrated 200-lumen LED flashlight proved invaluable during nighttime jump-starts, offering reliable illumination with multiple modes including strobe and SOS. While it won’t tackle heavy-duty trucks or large diesel rigs, it excels in passenger cars, SUVs, and light-duty trucks. The USB-C power bank delivers solid emergency charging for phones, though it lacks fast-charging output, making it better suited for short top-ups than full device recharges.

Compared to the NOCO GB20, the GB50 offers significantly more power and engine compatibility while keeping a similar compact footprint. It’s the ideal middle ground for budget-conscious buyers who still want dependable performance. Against the pricier GB70, it trades some peak amperage and capacity but wins on value and portability. For everyday drivers who need confidence without overspending, the GB50 delivers exceptional bang for the buck.

The NOCO Boost+Air AX65 redefines roadside rescue with its revolutionary all-in-one design—a 2000A jump starter, ultrafast air compressor, 60W power bank, and LED flashlight in a single rugged unit. This isn’t just a jumper; it’s a complete emergency toolkit that solves multiple car troubles in one go. The 67 SLPM airflow inflates a flat tire from 0 to 40 PSI in just two minutes—blazing fast compared to typical portable inflators. When paired with spark-proof UltraSafe 2.0, it delivers foolproof safety and pro-level performance for both jump-starts and tire maintenance.

During testing, the AX65 handled a V8 sedan with a dead battery and then inflated two SUV tires to proper pressure—all on a single charge. The digital pressure display is intuitive, allowing precise PSI, kPa, or bar settings, and the auto-shutoff ensures no overinflation. The 3-foot hose offers great reach, and the USB-C Power Delivery can charge laptops and tablets at full speed. However, the unit is heavier than pure jump starters, and while it can start engines up to 8.0L gas and 6.0L diesel, repeated cranking in extreme cold slightly reduced battery life.

Compared to the GB70, the AX65 offers far more functionality—especially the integrated air compressor—making it a smarter choice for frequent travelers or off-roaders. Against the GB150, it matches jump-starting power while adding inflation and faster charging. It’s pricier than basic models, but if you value versatility and speed, the AX65 justifies every penny with unmatched total utility.

At 5.0 lbs, it’s still manageable for glove box storage, though bulkier than smaller models.

In testing, the GB70 delivered consistent starts across multiple V8 engines, even after sitting idle for weeks. The IP65-rated housing shrugged off rain and dust during outdoor use, and the high-conductivity clamps ensured strong connections every time. It offers up to 40 starts per charge, outperforming many rivals, though the 6-hour recharge time is on the slower side. It lacks fast-charging or air inflation, but its pure focus on starting power and reliability makes it a workhorse for serious drivers.

Compared to the GB50, the GB70 offers double the starting capacity and higher lumen output, making it worth the upgrade for larger vehicles. Against the AX65, it misses the air compressor but wins on simplicity and lower cost. For drivers who want maximum jump-start reliability without extra features, the GB70 delivers unmatched performance in its class.
