Why we love this deal

Freezing-cold weather can be hard on vehicles, especially where older batteries are concerned. When the temperature drops, you might find that your car suddenly won’t start, especially after you haven’t driven for a few days. Whether it kills your battery for good or you just need a bit of a recharge, you can save yourself a lot of headaches by having a good portable jump starter on hand — the last thing you want to do is be stuck in some frigid parking lot far from home, waiting for a tow truck or family member to come save the day.

Instead, you might find a perfect solution at Amazon: the $60 AstroAI Jump Starter, which you can take home for only $40 at the moment. This top-selling battery charger, portable power station, and emergency flashlight makes for a great, practical gift or all-in-one road safety kit.

Why do shoppers love it?

Thousands of reviewers swear by this compact, easy-to-use jump starter. Its 12-volt lithium-nickel manganese cobalt (NMC) battery has a capacity of 10,000 milliamp-hour and a peak output of 1,500 amps, meaning it’s an ideal choice for quickly recharging a dead standard car battery when a bit of bad luck leaves you stranded out on the road. It also works great on everything from diesel engines and motorcycles to lawn mowers. The device measures just 7.9 inches in length and weighs 12.6 ounces, so it’s lightweight, a breeze to store and carry, and packs a big punch in a tiny, convenient package.

In addition to the starter, it also functions as a portable power bank, flashlight, strobe light, and SOS signal, so it’ll get you back on the road one way or another — even if your car’s too dead to jump. The jump starter is backed by a 2-year manufacturer’s warranty and is equipped with a host of safety features, including protection against over-charging, overloads, short circuits, high voltage, and more.

Details to know

Color options: Orange, red, and yellow.
Battery type: 12-volt lithium-nickel manganese cobalt (NMC).

“This is an excellent product,” said one satisfied shopper. “It’s compact enough to fit in the glove box, but I’ve been keeping it in my purse, so as not to leave it in a cold car. My car’s been having issues that drain the battery in this cold weather, so this has saved us three times already. I charge it to 100% before using it, and each time I only use 25% of the total charge to jump my car. It’s super fast — way faster than jumping from another car. You just plug in the jumper cables, attach them to the battery, and the car turns on right away. I’m very happy with this.”
