The battery in your Mustang only has one job to do, and that’s to provide enough power to start your car when you turn the key. This includes powering your ignition system (fuel system and computer if EFI), and powering the starter to turn the engine over. Other than that (and being used for accessory/reserve power when the engine is not running and the alternator providing power) the battery just kind of sits there under the hood. Like most items today that are “maintenance free” there’s not a whole lot you can do to modern batteries. They either hold a charge or they don’t. Gone are the days of adding water and checking battery condition with a hydrometer. So when you need your Mustang to start, be it to get to work, your Mustang club meeting, or just for that Sunday afternoon relaxation cruise, you want it to start. But what if it doesn’t?

For some, a dead battery is a minor inconvenience. You’ll just take a different car to that cruise night. For others, however, a dead battery could mean the difference between getting to work and getting fired! It’s especially disconcerting when your Mustang doesn’t start away from home, where you have no tools, no battery charger, or anything else to aid you. Sure, you can grab your cell phone and call roadside assistance, but do you really want to wait upwards of two hours for that tow truck? What about a helpful stranger? We’re sure they mean well, but we’ve seen plenty of helpful strangers hook up jumper cables improperly or do other damage. No reason to add insult to injury here, it’s just better to handle it yourself. So how do you get yourself back on the road and to home where you can be safe and diagnose the issue on your own time? The best answer is a portable jump pack.

The dimensions of the storage case are 8x5x3. It’s a little chunky for a late-model Mustang glove box but would fit under the seat. Alternatively, you can store just the JumperPack Mini and the included jumper cables in a much smaller profile, perfect for a center console.
Inside the included soft case is a foam storage side to protect the JumperPack Mini and a mesh pocket side to hold the charger, cables, and manual.
When removing the JumperPack Mini from the case instructions are printed right inside for easy reference.

In the past these portable jump packs were big, unwieldy boxes that took up a fair amount of trunk space and were quite expensive (think a shop-level tool purchase). Recently, Lithium-Ion battery technology has improved to the point that jump packs have come down in size, weight, and cost, but were somewhat limited in their capacity to jump larger engines. Most would handle four- and six-cylinder engines. Great for the wife’s Fusion, but what that nice V-8 Mustang in the garage? Cyntur has announced its JumperPack Mini, a 12,000Ah Lithium-Ion jump pack that has the power to start even V-8 engines. The JumperPack Mini even features a 2.1-amp USB port to emergency charge cell phones and other portable devices. Lastly, the built-in LED flashlight is perfect for finding your battery terminals under hood at night and can be used as an emergency S-O-S strobe light.

Cyntur’s new JumperPack Mini will hold a charge for up to a year, meaning it is ready when you need it. SafeJump technology means you don’t have to worry about reverse polarity or short-circuit issues when improperly connected to your car’s battery. It isolates itself and simply won’t work. Reverse the connections and you’re good to go. The small size and weight means it is easy for anyone in the family to handle it and make the connections, and it will fit in most storage consoles, glove boxes, or under a seat. The Cyntur JumperPack Mini is available now at www.cyntur.com and locally through an exclusive deal at Target stores. Cyntur dropped one on our doorstep to test and we were quite impressed. Check out the photos for more.

The JumperPack Mini is water resistant to protect it from rain and snow, but it is not waterproof. The end door illustration explains what each port does.
A quick press of the function button will illuminate the battery “fuel gauge” and turn on the USB port to charge devices.
Pressing and holding the function button for three seconds turns on the flashlight. Pressing it again changes to the S-O-S strobe function, and a third press turns the LED off.
If your device can be charged via a standard USB port (phone, tablet, GPS, camera) the JumperPack Mini can charge it. No charging cable is included however, so be sure your device cable is handy. We grabbed an extra micro-USB cable for our phone and added it to the soft case’s mesh storage pocket.
To use in an emergency simply plug the included jumper cable harness into the JumperPack Mini and connect red to positive and black to negative. There’s no need to press the function button for jump starting, just get in and twist the key and you’ll be safely on your way.
