What is a portable jump starter?
A portable jump starter is a tool you can use in lieu of a second car and jumper cables if you happen to get a dead battery and need a quick jump.
Why do you need a portable jump starter?
A portable jump starter is one of those things that you hope you won't need to use very often, but you'll be happy to have it when you inevitably do. It's not always easy, practical or safe to flag down another motorist to have them give you a jump when you're sitting with a dead battery. A portable jump starter allows drivers to be totally self-sufficient when it comes to finicky batteries. The convenience factor alone makes them worth it.
How do portable jump starters work?
Jump starters work in much the same way as traditional jumper cables, except that instead of using another vehicle as the power source, it uses a battery pack.
What size portable jump starter do you need?
This all depends on the vehicle you're planning to jump. Most jump starters come with information about the largest gas or diesel engines they can jump, so as long as you have that sized engine or smaller, you should be in good shape.
How do you use a portable jump starter?
With these devices, it's dead simple. First, make sure you have a compatible jump starter on hand and make sure it's fully charged and assembled. You'll want to connect the positive (+ or red) cable from the portable battery jumper to the positive (+ or red) post of the battery and the negative (- or black) cable to the negative (- or black) post of the battery. Red to red, black to black. Once the device is connected, simply head back into your car and try to turn it on. If all goes to plan, it should start right up.
Pros and cons of using a jump starter?
Jump starters are extremely convenient and can make an otherwise stressful situation involving a dead battery into, essentially, no big deal. Many people don't feel comfortable going up to a complete stranger to ask them for a jump and these devices make it so you'll never have to do so again. They're pretty affordable, most are made with sturdy materials and many are even multi-use.
One thing to keep in mind, though, is that not all jump starters are created equal. If you have anything bigger than an SUV, you'll want to do a little extra research to make sure the jump starter you're looking at is powerful enough for your vehicle. Another thing to watch out for is the length of the cables that come with your device. Some of them provide only just enough slack to get the job done, which can be frustrating and in some cases even dangerous.
