Will it start a diesel truck?

Yes. NOCO rates the GB70 for diesel engines up to 6 liters and gas engines up to 8 liters, covering most pickups, SUVs, boats and RVs.

How is it different from the GB40?

The GB40 is rated 1,000 amps for smaller gas engines. The GB70 doubles that to 2,000 amps and adds diesel coverage, a brighter light and more jump capacity.

Do I need to charge it before first use?

Charge it fully before storing it, then top it up every few months so it is ready when needed.

Can it charge my phone?

Yes. It has USB output for phones, tablets and wearables, and a 12V port for inflators and inverters.

What comes in the box?

The jump starter, heavy-duty battery clamps, a USB charging cable and a storage bag.

Is it safe to leave connected?

The clamps are spark-proof and protected against reverse polarity, so a wrong connection will not damage the unit or the vehicle.
