NOCO Boost Max GB250 12V 5250A Jump Starter: High Power for Heavy-Duty Starts

The NOCO Boost Max GB250 is one of the most powerful lithium-ion jump starters in the Boost Max series, designed to handle the largest and most demanding engine starts. Delivering a massive 5,250 amps peak current, this jump starter is capable of starting gasoline and diesel engines up to 16 litres, making it suitable for commercial vehicles, heavy trucks, motorhomes, buses, mining, agricultural, and construction equipment.

Compact Yet Powerful

Despite its tremendous power output, the GB250 is surprisingly compact and lightweight for its class, weighing approximately 15 pounds (around 6.8 kilograms). Its design incorporates high discharge lithium technology, which significantly reduces size and weight compared to traditional jump starters of similar capacity. The unit comes with a portable carrying case that makes it easy to transport and store, ensuring jump starts are more convenient than ever.

Safe and User-Friendly Design

Safety is front and centre with features like spark-proof technology and reverse polarity protection, which prevent accidental sparks and incorrect battery connections. This mistake-proof design helps protect both you and your vehicle during use. Additionally, the GB250 includes overcharge protection to ensure the internal battery remains healthy over time.

Integrated Diagnostics and Lighting

The GB250 features an integrated digital battery voltmeter, providing real-time diagnostics to help you assess battery health before jump starting. It also boasts an ultra-bright 600-lumen LED flashlight with seven light modes, including SOS and emergency strobe, making it a handy tool for roadside emergencies or work in low-light conditions.

Multi-Purpose Power Bank

Beyond jump-starting, the GB250 serves as a portable power bank with USB charging ports. It allows you to recharge smartphones, tablets, and other USB devices on the go, providing essential power when you need it most.

Practical Advice

For safe and effective jump starting, always connect the positive clamp to the positive battery terminal first and then the negative clamp to a solid grounded metal part of your vehicle, away from the battery’s negative terminal. Avoid cranking the engine for more than five seconds at a time and allow the jump starter to recover between attempts. Regular charging and proper storage will ensure your GB250 is ready whenever you need it.
