Small but powerful

The NOCO Boost Plus GB40 is a compact yet powerful jump starter that delivers reliable performance when you need it most. Rated at 1000 amps, this lithium-powered device can safely jump-start dead batteries in seconds, making it an essential tool for drivers of gasoline engines up to 6.0 liters and diesel engines up to 3.0 liters.One of its standout features is the UltraSafe technology, which ensures spark-proof connections and reverse polarity protection, eliminating the risk of incorrect hookups. This makes it user-friendly even for those unfamiliar with jump-starting procedures. Beyond its primary function, the GB40 doubles as a portable power bank, allowing users to recharge smartphones, tablets, and other USB devices on the go. The integrated 100-lumen LED flashlight with multiple modes, including emergency strobe and SOS, adds another layer of practicality, especially in roadside emergencies.Designed for durability, the GB40 features a rugged, water-resistant enclosure rated at IP65, ensuring it can withstand tough conditions. Its rubberized casing prevents scratches and enhances grip, making it easy to handle. Despite its robust build, it remains lightweight and compact, weighing just 2.5 pounds, which makes storage convenient.While the GB40 is highly effective for most standard vehicles, its jumper cables are relatively short, which may require positioning adjustments when connecting to certain battery terminals. Additionally, while it holds a charge well, users in colder climates may need to top it off periodically to ensure peak performance.Overall, the NOCO Boost Plus GB40 is a reliable and versatile jump starter that combines safety, convenience, and durability. Whether you're dealing with a dead battery or need a backup power source, this device is a solid investment for any driver looking for peace of mind on the road.

Saved Me on a Road Trip – Now I Won't Travel Without It

The NOCO Boost Plus GB40 is hands down one of the best tools I’ve ever bought. I keep it in my truck now, and it has already paid for itself. On a recent road trip, my battery died while I was parked at a gas station in the middle of nowhere. No one around to help, no jumper cables, and no roadside service for miles. I pulled out the GB40, hooked it up, and the engine fired up instantly. I was back on the road in minutes.Since then, I’ve used it on both my trucks and even my zero-turn mower. It starts everything quickly and without any hassle. The size is super convenient, and it fits easily in the glove box or tool storage. It’s really easy to use, even if you’re not great with tools.I also love that it has a built-in flashlight and can charge phones too. It’s one of those things you hope you never need, but when you do, you’re glad you have it.If you drive, especially out in rural areas or on long trips, this is a no-brainer. I won’t go anywhere without it now.

Works Great!

Worked perfectly. got a bad cell in my car battery, still had some juice, just not enough to turn over, just clicked when i turned the key.Hooked it up, correct sequence on lights flashed, which others have shown on video's. Went inside the car and started right up just like if the battery was good.Yes I need a new battery but those are much more expensive than what I paid for this. For a temporary thing, this worked awesome till next week when I can get a new car battery. I'll have it for emergencies at work or out and about when I do replace the car battery.Very good value for the money. Even came with enough of I charge I could use it successfully minutes after the Amazon driver delivered it! Thats unusual from normal when you order something online, Stuff has to be charged first.
