Ever been stuck on the road with a dead battery? It's not a fun experience. It's even less fun having to call roadside emergency or call a friend to come help. It's a series of unfortunate events that leaves you feeling drained and frustrated. Having one of Anker's emergency jump starters around can alleviate some of the annoyance by giving you a way to jump start your car immediately.

When fully charged, this device is capable of providing up to 15 jumps for your car. Just make sure the battery level is above 50% before using it and make sure the operating temperature is between 32 and 140 degrees Fahrenheit. It peaks at 400A and 12V and works on gas engines up to 2.8L, which is fine for your average car.

The jump starter moonlights as a battery charger, too. It's a 9000mAh battery, which is enough juice to recharge your phone a couple of times. The two high-speed USB ports can get you enough power to call for help or order a pizza while you wait or something.

There is a built-in high-intensity LED lamp you can use to see in the dark. The whole thing is IPX5 rated for water resistance, so you can use it in the rain without risk. And it uses a compact design so it's small enough to fit in your glove compartment.

Anker covers the jump starter with a one-year warranty, and users give it 4.2 stars out of 5 based on 137 reviews.
