'Works like a charm every time': This life-saving jump starter is down to $37 — it's 50% off!

It's easy to take for granted your car's ability to start up when you turn the key — until one day, it doesn't. Then, you're left with two options: Try to get a friend to come over and give you a jump, or call a mechanic for help. Both can cost you time and money, two things no one has available these days. Turns out, there's another solution. You can invest in a portable car jump starter to keep around for the just-in-case. And, just for today, Amazon has slashed the price on a top-rated DBPower portable jump starter to just $37.50 with an on-page coupon — that's a 50% markdown!

There's a lot to love about this jump starter, like the fact that it can jump your car up to 20 times on one charge with 800 amps of peak current and heavy-duty clamps and cables. It's also small enough to stash in your glovebox!

This jump starter is safe, too. Its spray gold intelligent jumper clamps have over-current protection, short circuit protection, overload protection, over-voltage protection and over-charge protection to keep you safe when you're giving your car a jump.

An LCD screen can show how much remaining power you have, while a built-in compass can help you get home if you're lost. Once you're ready, simply plug the jump starter in at home to fire it up again.

It's not just a car jump starter — the DBPower has a smart USB port to quickly and fully charge your laptop, phone, tablet and other devices.

With more than 4,000 five-star reviews, this jump starter has a serious army of fans. One happy user called the charger "extremely useful," writing, "I’ve used it twice already! Charges quick in the house, keep it in my trunk and it has every attachment you could ever need!! Plus now I’ll be able to help someone else out when they’re in need!!"

"I love this little guy," raved another charged-up customer. "It is so handy. I have used it for my lawn mower, boat, truck etc! Works like a charm every time. My friends are all impressed I’ve already ordered two more of these as gifts."

Another fan said they've used the battery more than six times and it's been "solid" each time. "I’ve helped a couple people stalled in the parking lot at work, so I’ve used it on four different batteries and cars," they wrote. "It’s also been able to hold a 100 percent charge for at least a couple of months. It’s paid for itself four times over. VERY satisfied with this product!"

Sure, the hope is that you'll never actually have to use a portable jump starter. But it's important to be prepared just in case it happens to you.
