A batteryless jump starter is maintenance-free and needs no charging priortouse.

Car troubles strike when you least expect them, and the three most common reasons to call a tow truck or roadside assistance are a flat battery, a flat tire, or no fuel.

When it comes to a flat battery, numerous jump starters exist that you can attach to the battery to give it a boost to get your car going.One of my favorite brands is Noco, and the company offers a range of jump starters -- fromsmall to enormous .

The only catch to these jump starters is that you have to keep them charged up. And if the jump starter happens to be flat itself when you need to use it, it can take hours to charge up to the point where it will in turn fire up a vehicle.

This is wherebatteryless jump starters come into play.
