Amazon currently has the Anker PowerCore Jump Starter Mini on sale today for just $59.99. That's good for about $100 off of its regular price, making this an insane deal for this jump starter. This is part of Amazon's Gold Box Deal of the Day, so it's only good through today. So you'll want to grab one before its gone.
The Anker PowerCore Jump Starter Mini is essentially a portable battery pack that can jump start your car. It works on gasoline engines up to 2.8L, which is going to work for most vehicles (but may not work on some larger SUV's and vans). This battery is able to jumpstart your car around 15 times from a single charge. So you can just keep this in your car and use it to jump start your battery whenever it dies. It does come with a pair of jumper cables, and has a pretty large and bright flashlight built-in. Making it easier for you to see in the dark, in case you do get stranded in the dark. Anker does have about four LED lights on the PowerCore Jump Starter Mini to indicate how much juice is left on the battery pack, which can really be very helpful. This is a great accessory to pick up, especially if you do a lot of driving.
