Boost X GBX45 1250A 12V UltraSafe Portable Lithium Jump Starter, Car Battery Booster Pack, USB-C Powerbank Charger, and Jumper Cables for Up to 6.5-Liter Gas and 4.0-Liter Diesel Engines

This is the sort of device that sits in your car forever with very occasional use (unless you are a road service provider). So it needs to hold its charge, handle variable temperatures, and work seamlessly when required. It achieves all of these aims. I bought the additional case to make sure it stays together and doesn't get damaged, and that's worth the extra (on sale). It sits behind my car's rear wheel well and gets pulled out on the rare occasions it's needed, when its simple and clear design makes it easy to operate without reading a big manual. Only downside is the price, but there's no point paying less and having no charge when you need it.

Genial. Vale cada centavo. Tuve oportunidad de utilizarlo a los pocos dias de la compra. Es muy fácil de usar, efectivo, inmediato. Al primer intento de usarlo encendí mi auto sin ayuda. Me parece una excelente compra. Pequeño para traer en el auto, ademas permite ayudar a otras personas sin tantas dificultades de acomodar los autos etc. De ahora en adelante lo traeré siempre con mis cosas de emergencia en el coche. Ah y lo cargue en menos de una hora con un cargador de 30 w, y puede usarse uno de 60w. sin problema.

Purchased this as we have many things that may require a jump start. It charges quickly and is very easy to hook up and jump start anything we need it for. It is a nice, compact size and comes with a carrying case. It works great and we would highly recommend it.

I’ve owned several portable jump starters over the years, including the older NOCO GB40. While the previous generation was "good enough," the NOCO Boost X GBX45 feels like a serious professional-grade tool rather than just a backup gadget. If you’re deciding between the older "Plus" models and this new "X" series, here is the real-world breakdown of why this is worth the extra $20-$30. 1. USB-C Power Delivery is a Game Changer The biggest frustration with older lithium jump packs was the recharge time—often taking 3 to 5 hours via Micro-USB. The GBX45 uses USB-C PD (60W). I can fully charge this unit in about 48 minutes. Even more impressively, if it’s dead and you’re stranded, you can plug it in for just 5 minutes and it will have enough "juice" to perform a jump. That alone justifies the upgrade. 2. Performance on Larger Engines I tested this on a 5.7L V8 that had been sitting for three weeks in 30°F weather. The battery was at roughly 2V (dead as a doorknob). The Result: The "Boost" light kicked on, and the engine turned over instantly without that sluggish "struggling" sound you get with smaller packs. The Specs: It’s rated for 6.5L Gas / 4.0L Diesel, which covers almost any standard pickup truck (F-150, Silverado) or SUV on the road. 3. Safety for the "Non-Car" Person The UltraSafe 2.0 technology is foolproof. I let my daughter use it on her car, and even though she was nervous about "sparks" or "blowing something up," the reverse polarity protection makes it impossible to mess up. If you hook it up backwards, it simply won't engage. 4. More Than Just a Jump Box The 60W output means this isn't just for car emergencies. It functions as a high-speed power bank. It can fast-charge a MacBook Air or an iPhone 15 at full speed. The 100-lumen flashlight is surprisingly bright with a wide beam, making it actually useful for changing a tire at night, not just a gimmick. Pros: Lightning Fast Charging: 0% to 100% in under an hour (with a 60W wall plug). Extreme Power: Delivers a much higher "punch" (1250A) than the GB40. Compact: Still fits in a standard glove box or under a seat. Manual Override: Works on "deeply discharged" batteries (below 2V) that other smart chargers won't even detect. Cons: Case Sold Separately: It comes with a microfiber bag, but for a tool at this price point, I really wish it included the hard-shell protective case. No Wall Plug: It includes the USB-C cable, but you’ll need your own 60W USB-C brick to get those ultra-fast charging speeds. The Bottom Line: The GBX45 is the "Goldilocks" of the NOCO lineup. It has the modern USB-C tech the older units lack and enough power to handle a dead truck battery without being as bulky or expensive as the commercial-grade GBX155. It's the best insurance policy you can put in your trunk.
