10 Best Type S Jump Starters 2026 in the United States

The NOCO Boost GB40 is a compact and powerful jump starter designed for cars with engines up to 6.0L gasoline or 3.0L diesel. It delivers a strong 1000 amps of peak power, enough to start dead batteries quickly and efficiently. Its lithium-ion battery supports up to 20 jump starts on a single charge, which is quite handy if you face multiple emergencies before recharging. Safety is a major plus here, thanks to its spark-proof design and reverse polarity protection, so you can connect it without worrying about damaging your vehicle or the device. Portability is well thought out—the GB40 weighs just 2.4 pounds and is small enough to fit in a glove box or emergency kit, making it easy to carry around. The rugged housing resists water, dust, and impacts, so it holds up well in tough conditions.

Besides jump starting, it doubles as a power bank to charge phones or tablets, recharging itself in about 3 hours. It also includes a bright 100-lumen LED flashlight with useful modes like SOS and strobe for emergencies or night use. On the downside, while the battery capacity supports multiple starts, some users might wish for even longer standby times or faster recharge rates. Also, it’s designed for smaller to mid-sized engines; larger vehicles may need a more powerful model.

In conclusion, the NOCO Boost GB40 provides a reliable, user-friendly jump starter that balances power, safety, and portability, making it a great choice for everyday drivers who want peace of mind without fuss.
