Performance Tests
Performance is what separates a convenient tool from an essential one. This section summarizes real-world and laboratory-style checks on starting capability, recharge behavior, and device charging performance so you can sense how the unit will behave when you need it most.
Cold-Weather Starts
Cold cranking amps and chemical behavior in cold conditions are major factors for jump starters. The GB150’s lithium chemistry and heavy-duty clamps allow it to provide a strong initial burst of current in cold weather, which improves the odds of starting heavily taxed batteries on frosty mornings. In extremely cold climates, it’s still wise to keep the unit insulated, but overall the GB150 performs reliably in sub-freezing conditions compared with many competing units.
Repeated Starts and Battery Life
When you need multiple starts in a row — such as helping several vehicles or performing repeated tests — the GB150 holds up well. NOCO claims up to 80 starts per charge on smaller engines; for larger engines, you’ll see fewer starts but still a substantial number. The unit’s high-discharge lithium pack is engineered to deliver multiple high-current pulses without overheating or obvious sagging.
Charging Time and Cycle Life
Charging the GB150 via USB-C takes about seven hours from empty to full, which is reasonable for a high-capacity lithium pack. You should expect typical lithium cycle life characteristics: hundreds of cycles before noticeable capacity loss, provided you follow charging and storage recommendations. Keeping the unit topped up between uses will extend its usable lifetime.
Device Charging (Power Bank)
As a power bank, the GB150 offers emergency charging for phones, tablets, and small USB devices. It won’t replace a dedicated high-capacity power bank for extended off-grid use, but for charging low-to-medium-draw devices in emergencies it is very effective. The USB-C port makes recharging the unit easier and adds compatibility with modern cables and chargers you already own.
Safety Features Explained
You’re dealing with high currents and vehicle batteries, so safety is central to the design of the GB150. Knowing how these systems work gives you confidence when you need to make a connection in adverse conditions.
Spark-proof and Reverse Polarity Protection
The GB150 employs circuitry that prevents sparks and detects reverse polarity, blocking the current if clamps are connected incorrectly. That protection significantly reduces the risk of accidental shorting or damage to either the jump starter or the vehicle’s electronics, giving you a safer, more stress-free experience.
High-Conductivity Clamps
The included clamps are designed to deliver maximum energy transfer to the vehicle battery with minimal resistance. Sturdy clamps make it easier to get a reliable connection even when battery posts are corroded or irregular, and they reduce the heat generated during high-current transfers.
IP65 Rating and Rugged Housing
With an IP65 rating and rubber over-molding, the GB150 resists dust and water spray and can handle bumps and minor drops you’re likely to encounter in roadside situations. That ruggedness gives you peace of mind that the unit won’t fail because of a little rain or rough handling in an emergency.
Real-World Scenarios
Understanding how a unit behaves in realistic situations helps you decide whether it aligns with your needs. These practical scenarios show where the GB150 shines and what to expect when you rely on it.
Roadside Emergency
If your car dies on the side of the road, the GB150 is designed to get you moving quickly with minimal fuss. The safety features and flashlight remove a lot of the anxiety from nighttime or remote starts, allowing you to make a safe connection and get back on the road.
Fleet and Professional Use
For fleet managers or service techs who need repeated reliable starts, the GB150’s high peak current and durability are beneficial. While it’s compact, its starting power and rugged design make it a viable backup tool for commercial use where multiple starts and reliability are crucial.

How to Use the NOCO Boost GB150
Using the GB150 is straightforward, but following a clear sequence keeps you safe and increases success rates. Below are steps and recommendations so you can use the unit confidently when it matters.
- Ensure the GB150 is charged: The unit’s indicator lights will show charge level. Regularly top up the unit so it’s ready when you need it.
- Turn off the vehicle and accessories: Make sure lights, heaters, and radios are off before connecting clamps. Reducing parasitic draw helps the starter deliver effective current to the battery.
- Attach clamps: Connect the positive clamp to the positive battery terminal and the negative clamp to a grounded metal surface away from the fuel system, not directly to the negative terminal if you prefer extra safety. The GB150’s reverse-polarity protection will prevent damage if you misconnect, but correct connections are always best.
- Start the vehicle: Once connected, start the vehicle. If it doesn’t start immediately, wait a few moments and try again. Avoid cranking continuously to prevent overheating.
- Remove clamps: Once the vehicle starts, remove clamps in reverse order (negative first, then positive). Allow the vehicle to run to recharge its battery and then recharge the GB150 as soon as possible.
Following these steps just a few times will make using the GB150 second nature.
Maintenance and Storage Tips
Proper care extends the life and reliability of your jump starter, giving you confidence that it will work when you need it. Small habits go a long way in maintaining performance.
- Keep the unit charged: Store the GB150 with a partial charge and top it up every few months if not used. Lithium batteries prefer being maintained rather than left empty for long stretches.
- Store in a cool, dry place: Avoid extreme temperatures; high heat and persistent freezing reduce battery life. The included microfiber bag helps protect against dust and minor physical damage.
- Inspect clamps and cables: Periodically check for corrosion or fraying and clean clamp contact surfaces with a wire brush if needed. Faulty clamps reduce performance and can be dangerous.
- Clean the exterior: Wipe down the housing and flashlight lens to ensure long-term durability and functionality.
These steps are easy and don’t require technical knowledge, but they preserve the unit’s readiness.
Troubleshooting Common Issues
Even the best tools can encounter small problems. Here are common issues you might face with suggested fixes so you can resolve them quickly without getting stranded.
Unit Doesn’t Start the Vehicle
If the vehicle doesn’t start after connection, verify clamp contact and polarity and give the unit a few minutes to deliver charge. Also consider that the vehicle’s battery or starter may be deeply sulfated or mechanically failing — in those cases the jump starter may offer limited improvement.
Clamps Won’t Make Solid Contact
Clean battery terminals and clamp jaws, tighten connections, and reposition clamps on clean metal. Corroded posts or irregular shapes can interfere with current transfer, so ensure secure, clean contact.
Unit Not Holding Charge
If your GB150 loses charge quickly, ensure you’re charging it fully and storing it according to recommendations. If the issue persists, it could be a battery or charging circuit fault; consult NOCO support for diagnostics under warranty.
