NOCO reports about a 6-hour recharge time, which is reasonable for a high-capacity lithium pack. You’ll want to charge it overnight before heading out on long trips or when you know you’ll be storing it for an extended period and need it topped off.
Integrated LED flashlight
The 400-lumen LED is bright and versatile, giving you focused light for engine compartment work or broader illumination when you need to be seen. The integrated light is a genuinely useful addition rather than a gimmick.
Light modes and practical use
Seven light modes, including high, low, strobe, and SOS, give you flexible lighting options. You can use the strobe or SOS in an emergency to signal for help, and the focused beam helps when you’re attaching clamps in low-light conditions.
Battery life and maintenance
Lithium battery packs like the GB70 maintain charge better than older chemistries and are lighter for the amount of stored energy they provide. You’ll still want to follow a few simple maintenance steps to keep performance consistent.
Storage and long-term health
Store the unit in a dry place and periodically recharge it if you don’t frequently use it — maintaining the battery at roughly 50–80% charge is generally best for long-term health. If you leave it discharged for months, you may shorten its lifespan, so periodic charging every few months is a good practice.
Included accessories and packaging
You get everything you need to start using the unit out of the box: heavy-duty clamps, a USB-C charging cable, and a microfiber storage bag for tidy storage. The included bag helps protect the unit from scratches and keeps the cables organized, which you’ll appreciate when you’re under time pressure.
How to use the NOCO Boost GB70
Using the GB70 is straightforward, which reduces the stress when you need it most. The controls are intuitive and the unit’s safety features help you avoid common mistakes.
Step-by-step jump starting
First, make sure the GB70 is charged. Turn off the vehicle’s ignition and electronic accessories, then connect the clamps to the vehicle battery — positive clamp to positive terminal, negative clamp to a solid engine ground point if recommended. Attach the clamps to the GB70, and press the power button to initiate the start sequence. Start the vehicle, and once running, disconnect clamps in reverse order. You’ll appreciate that the GB70’s spark-free protection reduces your worry about accidental sparks during this process.
Charging the unit safely
Plug the USB-C cable into a 5V/2A or higher source as recommended and connect it to the GB70’s USB-C input. Charge on a stable, grounded power source and avoid charging in extremely cold or wet conditions. You’ll want to avoid leaving it plugged in constantly for extremely long durations; periodic top-offs are best.

Comparisons
Comparing the GB70 to other options helps you match its strengths to your needs and budget.
NOCO Boost GB70 vs smaller NOCO models
Compared with smaller NOCO units, the GB70 provides significantly more starting power and a higher engine size rating, which is critical if you drive a truck, heavy SUV, or diesel vehicle. If you primarily drive a compact car, a smaller, less expensive NOCO model may be adequate, but you’ll sacrifice the ability to start larger engines reliably.
NOCO Boost GB70 vs traditional jumper cables
Traditional cables require another vehicle with a working battery, cooperation from the other driver, and some knowledge of proper cable hookup to avoid damage. The GB70 frees you from relying on another vehicle and includes safety features to minimize user error, making it far more convenient and safer for solo drivers.
Common problems and troubleshooting
You might run into a few scenarios where the unit doesn’t behave as expected; these are typically solvable with basic checks and simple steps.
- If the GB70 won’t turn on, make sure it’s charged and that the clamps are connected properly. A deeply discharged pack might require a short recovery period before it accepts a full charge.
- If the vehicle doesn’t start, recheck clamp connections, ensure the vehicle ignition is off during connection, and allow the GB70 to sit connected for a moment to stabilize voltage before attempting to crank.
- If you get a polarity error warning, disconnect immediately and reposition the clamps correctly. The built-in protection prevents damage, but you’ll want to double-check connections before trying again.
