Meet the NOCO Boost GB40— a compact 1000A lithium jump starter that can start up to 6.0L gas or 3.0L diesel engines, plus double as a power bank and emergency flashlight. In this video I unbox it, show how to use it safely, and test it on a real dead battery.

✅ Highlights

Starts most 12V vehicles: cars, motorcycles, ATVs, trucks, boats

UltraSafe tech: spark-proof + reverse polarity protection

Up to ~20 jump starts per charge (usage dependent)

Built-in 100-lumen LED (SOS & strobe)

Portable power bank for phones/tablets

Rugged, compact design (glove-box friendly)

📦 What’s in the box
GB40 unit, heavy-duty clamps, USB-C cable, microfiber bag, user guide.

📝 Tips

Fully charge before storing; top up every 2–3 months.

Use Boost Mode only when the unit can’t detect the battery.

After starting, let your vehicle run to recharge its alternator/battery.

🔁 Alternatives

GB20 (500A) for small gas engines

GB50 (1500A) for larger gas/diesel

GB70 (2000A) for big trucks/regular heavy use
