We’re right in the middle of Amazon’s extended Prime Day event, and that means now is an excellent time to pick up automotive gear like this tire foam spray or this diagnostic tool, all at a greatly discounted price. Even the retail giant’s bestselling jump starter is 36% off right now, and it's a must for summer car travel.

The Noco Boost GB40 Portable Jump Starter is down to $80 for Prime Day. In addition to being the most popular jump starter on Amazon, it's also No. 1 bestselling product in Amazon's entire automotive category. This unit has been purchased over 30,000 times in the past month alone, and it's swiftly closing in on a monumental 100,000 five-star ratings from shoppers. If you want to join the tens of thousands of shoppers who happily rely on a Noco Boost GB40, you should act now, because the sale price goes away on July 11.

Noco Boost GB40 Portable Jump Starter, $80 (was $125) on Amazon

The Noco Boost GB40 uses a patented spark-proof design to charge 12V vehicle batteries in an “ultrasafe” way. Weighing only 2.4 pounds itself, a fully-charged Noco Boost GB40 can, on a single charge, perform up to 20 starts for dead batteries with its 1,000 amp power. It even has a built-in flashlight for nighttime charging and SOS and strobe modes for when a simple jump won’t do. The Noco Boost GB40 is also compatible with gas engines up to 6.0L and diesel engines up to 3.0L.

One shopper pointed out that the Noco Boost GB40 is “incredibly safe and simple” and said, “With spark-proof clamps and reverse-polarity protection, it’s nearly foolproof—even if you hook it up wrong, nothing bad happens.”

Another shopper recounted using it on their older car. “It started my 2002 Chevy Suburban in under 30 seconds. The light is plenty to light up an engine bay and has multiple brightness settings and multiple strobe settings (slow strobe and a fast strobe). The fact that it has a USB port to charge devices was very attractive to me. I would include charging cables in the bag it comes with, just so you know you have what you need to charge up in an emergency.”

This bestselling jump starter is only $80 for Prime Day, but it is so popular that this price might be the catalyst for it finally selling out. Buy yours now if you want one.
