NOCO Boost GBX55 1750A Review: Powerful, Safe, and Fast to Recharge

A dead car battery always seems to happen at the worst time. You may be leaving work, heading to an appointment, or parked far from home when the engine gives you nothing but a click. Waiting for roadside help is frustrating, and asking another driver for a jump is not always practical.

The NOCO Boost GBX55 1750A is built for that exact problem. This portable lithium jump starter delivers up to 1,750 amps and is rated for gas engines up to 7.5 liters and diesel engines up to 5.0 liters. It also works as a USB-C power bank for phones, tablets, and laptops.

What makes the NOCO Boost GBX55 1750A noteworthy is its mix of starting power, safety features, and fast charging. It is not the smallest jump starter in the NOCO range, but it offers enough output for larger vehicles while remaining far easier to store than a traditional booster pack.

What is the NOCO Boost GBX55 1750A?

The NOCO Boost GBX55 1750A is a rechargeable 12V lithium-ion jump starter. It connects to a vehicle battery with included heavy-duty clamps. Once connected, it can supply the burst of power needed to start a vehicle with a weak or drained battery.

Its 1,750-amp rating places it in the higher-power section of the Boost X lineup. NOCO rates it for gas engines up to 7.5L and diesel engines up to 5.0L. That makes it suitable for many cars, trucks, SUVs, vans, boats, and recreational vehicles.

• ⭐ Peak current: 1,750 amps
• ⭐ Voltage: 12V automotive systems
• ⭐ Gas engine rating: Up to 7.5L
• ⭐ Diesel engine rating: Up to 5.0L
• ⭐ USB-C output: Up to 60 watts with Power Delivery
• ⭐ Recharge time: About 1.2 hours with suitable USB-C Power Delivery
• ⭐ Jump starts per charge: Up to 9, depending on vehicle and battery condition
• ⭐ Protection: Spark-proof and reverse-polarity protection

The target audience is broad. It suits daily drivers, truck owners, families, road trippers, boat owners, and anyone who wants emergency starting power without carrying a large lead-acid booster.

Key Features of NOCO Boost GBX55 1750A

1. Strong 1,750-Amp Starting Power

The headline feature is the 1,750-amp peak rating. That gives the NOCO Boost GBX55 1750A enough reserve for larger engines than many compact jump starters can handle. It is rated for gas engines up to 7.5L and diesel engines up to 5.0L.

In practical terms, this is useful for full-size pickups, large SUVs, work vans, and some recreational vehicles. A higher output rating does not guarantee a start in every situation. A frozen engine, damaged starter, poor cable connection, or failed battery can still prevent the vehicle from starting. However, the added power gives the unit a better chance when the battery is simply too weak to crank the engine.

2. UltraSafe 2.0 Protection

Connecting jumper cables can make people nervous, especially in poor light. The UltraSafe 2.0 system is designed to reduce that stress with upgraded spark-proof and reverse-polarity protection.

If the clamps are connected incorrectly, the unit is designed to warn you rather than immediately send power through the connection. This is a major benefit for first-time users. Still, I would always check the positive and negative terminals before pressing the boost button. Safety systems help, but careful setup remains important.

3. USB-C Turbo Charging

The NOCO Boost GBX55 1750A can recharge in about 1.2 hours when connected to a compatible USB-C Power Delivery charger. It can also gain enough charge for a jump start in about five minutes, even when the unit is fully depleted.

This fast-charge feature is valuable when the jump starter was forgotten after a previous use. You may not have to wait several hours before helping yourself or another driver. The five-minute claim depends on using the right charger and conditions, so a basic low-power USB adapter will not provide the same result.

4. Integrated 60-Second Timer

High-voltage jump starters can waste energy if they remain active for too long. The integrated 60-second timer helps control power use during a starting attempt.

The timer gives you a clear window to crank the engine while helping preserve battery capacity. NOCO states that the unit can deliver up to nine jump starts per charge. Actual results will vary with engine size, temperature, battery condition, and how long you crank the vehicle.

5. 60-Watt USB-C Power Delivery

This is more than a jump starter. The USB-C Power Delivery port can charge phones, tablets, and some laptops. Dual-direction charging also lets the unit act as a high-output portable power bank.

That makes it useful during travel, camping, roadside emergencies, and power outages. A phone can be critical when you need roadside assistance. Having a way to charge it from the same device that starts your vehicle adds real convenience.

6. Portable Design for Emergency Storage

The NOCO Boost GBX55 1750A is much easier to store than a traditional jump box. It can remain in a trunk, cargo area, garage, or workshop without taking up the space of a full-size battery pack.

Its compact design does not remove the need for care. Keep it dry, avoid extreme heat when possible, and recharge it after use. Like any lithium battery, it should not be treated as a permanent replacement for a vehicle battery charger.

How Does NOCO Boost GBX55 1750A Perform?

Starting a Daily Driver

For a typical four-cylinder or V6 vehicle with a weak battery, the NOCO Boost GBX55 1750A should feel comfortably overqualified. The 1,750-amp rating provides more starting reserve than many drivers will need.

In my evaluation of the feature set, the biggest benefit is not only raw power. It is the simple operating process. Charge the unit, attach the clamps, confirm the indicator, and start the vehicle. The timer and safety alerts reduce guesswork during a stressful moment.

Handling a Large Gas Truck

Large gas engines need more cranking power, especially in cold weather. The GBX55 is designed for engines up to 7.5L, so it is a better fit for full-size trucks and SUVs than entry-level jump starters.

Performance will still depend on the battery. If the battery has a loose terminal or has failed internally, a jump starter may not solve the problem. For a normal low-charge situation, though, the unit has the output expected from a premium portable booster.

Starting a Diesel Vehicle

Diesel engines can place greater demands on a jump starter because of their compression and glow-plug systems. The NOCO Boost GBX55 1750A is rated for diesel engines up to 5.0L, which covers many common pickups and commercial vehicles.

For larger diesel engines, heavy equipment, or repeated commercial use, a stronger professional booster may be more suitable. For personal trucks and emergency use, this model offers a useful balance of size and power.

Charging Devices on the Road

The 60-watt USB-C port is a practical bonus. It can charge a modern phone quickly and may provide enough power for some tablets and laptops. This makes the GBX55 more useful than a jump starter that sits untouched in the trunk.

However, the battery capacity is limited compared with a dedicated laptop power bank. Its main job is still vehicle starting. Think of device charging as an emergency feature rather than its primary purpose.

Is NOCO Boost GBX55 1750A Right for You?

The NOCO Boost GBX55 1750A is a strong choice for drivers who want more reserve power than a small emergency starter can provide.

• 🎯 Truck and SUV owners: The larger engine rating makes it a better match for full-size vehicles.
• 🎯 Frequent travelers: It adds confidence on long trips and provides backup power for mobile devices.
• 🎯 Families: One unit can support several vehicles and help during roadside emergencies.
• 🎯 Outdoor users: It can support camping, boating, and remote travel where another vehicle may not be nearby.

You may want to skip it if you drive a small car and only want the cheapest possible jump starter. You should also consider a traditional charger if your main goal is battery maintenance. The GBX55 starts vehicles; it does not replace a smart battery maintainer.

Is NOCO Boost GBX55 1750A Worth the Price?

The listed price is $132.99. That puts the NOCO Boost GBX55 1750A above basic 12V jump starters, but the price is supported by its higher output, fast USB-C recharge, safety controls, and device-charging ability.

Cheaper models may be adequate for compact cars. They often have lower engine ratings and slower charging. Premium alternatives may offer similar power, but some cost more or lack the GBX55’s combination of compact design and 60-watt USB-C output.

In my view, the long-term value is strongest for truck owners, families with several vehicles, and people who drive in remote areas. If it prevents even one tow call or missed appointment, the purchase can pay for itself quickly. The value is weaker for someone who rarely drives and already has reliable roadside coverage.

Frequently Asked Questions About NOCO Boost GBX55 1750A

Can NOCO Boost GBX55 1750A start a completely dead battery?

It can help start a vehicle with a severely discharged battery, but results depend on the battery’s condition. A battery with an internal failure, damaged cables, or a serious electrical fault may not respond to any portable jump starter.

What engine size can NOCO Boost GBX55 1750A handle?

It is rated for gas engines up to 7.5 liters and diesel engines up to 5.0 liters. These are maximum recommended ratings, not guarantees for every vehicle or weather condition.

How long does NOCO Boost GBX55 1750A take to charge?

With a compatible USB-C Power Delivery charger, it can recharge in about 1.2 hours. A lower-power charger may take longer. Always check the charge indicators before storing it for emergency use.

Can it charge a laptop?

Its 60-watt USB-C Power Delivery output can charge some laptops and many tablets. Compatibility depends on the laptop’s power needs, cable, and charging system.

How many jump starts can it provide?

NOCO states that it can provide up to nine jump starts per charge. The actual number varies with engine size, temperature, battery condition, and the length of each starting attempt.

Is it safe for beginners?

Yes. The spark-proof design and reverse-polarity protection make it more beginner-friendly. Even so, users should identify the positive and negative terminals and follow the included instructions.

Can I leave it in my car?

You can store it in a vehicle, but avoid prolonged exposure to extreme heat or freezing conditions. Keep it dry and inspect the charge level regularly.

Does it replace a car battery charger?

No. A jump starter provides short bursts of power to start an engine. A battery charger or maintainer is the better tool for slowly restoring and maintaining battery charge.

Final Verdict: Should You Buy NOCO Boost GBX55 1750A?

Overall rating: ★★★★☆ 4.5/5

The NOCO Boost GBX55 1750A is a capable emergency jump starter with enough output for many large vehicles. Its UltraSafe 2.0 protection helps reduce connection errors, while USB-C Power Delivery makes charging much faster than older designs.

I especially like the balance between power and portability. It is strong enough for many trucks and SUVs, yet it can still live in a trunk without becoming a burden. The 60-watt USB-C port adds useful value when traveling.

The main drawback is price. Small-car owners may not need this much power, and the unit does not replace a proper battery charger. For drivers who need dependable backup power, however, those limitations are reasonable.

Conclusion: NOCO Boost GBX55 1750A Review Summary

The NOCO Boost GBX55 1750A combines 1,750 amps of starting power, broad engine compatibility, spark-proof protection, rapid USB-C charging, and portable device support. It is a practical tool for roadside emergencies, travel, work vehicles, and outdoor use.

I recommend it for truck and SUV owners, families, and anyone who wants a reliable backup instead of depending on another driver. If you only need a basic starter for a small car, a less powerful model may save money. Otherwise, the NOCO Boost GBX55 1750A is a well-rounded choice that earns its premium position.

💡 Keep it charged, store it carefully, and place it in your vehicle before the next dead-battery emergency. You may never need it—but when you do, having it nearby can make a stressful situation much easier.
