NOCO Boost X GBX45 1250A Jump Starter — 6.5L Gas / 4.0L Diesel, USB-C PD Power Bank

NOCO Boost X GBX45 — A 1250 Amp Jump Starter You Can Trust

Meet the GBX45, a high performance portable jump starter designed to handle demanding starts with ease. It delivers 1,250 amps to fire up gas engines up to 6.5 liters and diesel engines up to 4.0 liters. The heart of its safety is UltraSafe 2.0, a smart design that provides spark-proof connections and reverse polarity protection, along with enhanced thermal efficiency to protect both the device and your battery. A built-in 60-second timer helps conserve energy while keeping enough juice available for multiple starts on a single charge.

You’re not just buying a jump starter; you’re getting a multi-use power tool. The GBX45 features a 60 watt USB-C Power Delivery port that supports both input and output, turning Boost X into a robust portable power bank for phones, tablets, laptops, and USB-C devices. When you’re away from a wall outlet, you can rely on this dual-direction charging to top up or power essential devices on the go, from a road trip to a campsite or a remote job site.

In low light or during roadside work, the 100-lumen LED flashlight is ready with seven modes including SOS and strobe. The light is compact but bright enough to illuminate engine bays, tool drawers, or reflective surfaces on a dark street. The GBX45 arrives ready to go with heavy-duty clamps, a USB-C charging cable, and a microfiber storage bag, all backed by a one-year warranty and proudly engineered in the USA.
