Will the GBX75 start a diesel truck?

Yes. NOCO rates it for 12-volt diesel engines up to 6.5 liters and gasoline up to 8.5 liters.

How long does it take to charge?

About 5 minutes of USB-C charge is enough to attempt a jump. A full recharge takes longer, depending on the charger.

Can it charge my phone or laptop?

Yes. The USB-C Power Delivery port works as a power bank for phones, tablets, laptops and wearables.

Is it safe to leave connected?

UltraSafe 2.0 includes spark-proof and reverse-polarity protection, so a mistaken clamp connection should not damage the pack or vehicle.

Is it worth the price over a smaller NOCO?

If you own a large truck, SUV, RV or diesel, the extra amps justify the cost. For a small car or motorcycle, a lower-amp model is enough.

What comes in the box?

The GBX75 pack, heavy-duty battery clamps and a USB-C charging cable.
