The invention of the portable car jump starter revolutionized a small part of the auto service industry. These jump starters brought hope that the days of drivers being stuck on the roadside for hours waiting for a mechanic to help them will soon be gone.
The Spirit A8 car jump starter is one of the most popular portable jump starters in the U.S.
Compared to jump-starting your vehicle with the help of another car, the portable jump starter is quicker, cleaner, and safer. Despite these obvious benefits of ownership, portable jump starters have not yet gained the universal acceptance they deserve.

Choosing a Car Jump Starter
If you’re looking to purchase a car jump starter, here are some important factors you’ll need to consider.
Can revive a dead battery
It might sound obvious, but don’t merely expect a jump starter to restart a dead battery unless the product description states it. For example, there are many jump starters that can top-up a low battery but don’t have enough power to restart a dead source.
You’ll need to store your car jump starter in your vehicle for desperate times. Although a bulky device will have plenty of power that you need, you’ll require a lightweight, small unit to store in your trunk. The average jump starter weighs around 20 pounds, so aim to keep the weight below this for portability purposes.
The cable length plays a significant role in where you’ll place your jump starter during use. Your desired location depends on your personal preference. If you store the jump starter on your car’s hood during use, a small cable length will suffice. On the other hand, if you intend to keep the device on the floor while you charge your car, you’ll need a cable length that can reach the jump starter and your car from a farther distance.
Finally, you’ll require a voltage that suits your vehicle. The average car comes with a 12-volt battery. But if you own a truck or bus, this will likely be 24 volts, so choose a device that matches your vehicle’s requirements.
The Spirit A8 car jump starter is a high-quality unit that will meet the needs of most car and SUV owners. In addition to reliable jump starting, the A8 comes with a variety of laptop, phone, and tablet chargers.
However, a careful comparison of the features of the jump starters on our list reveals that the DBPOWER jump starter is the best jump starter overall. Equipped with an 18,000mAh battery, an eight-in-one laptop jack, two 2.4A phone charging ports, a flashlight, and a compass, this jump starter is cheaper, more versatile, more reliable, and more durable than the Spirit A8 car jump starter.
Drivers of heavier vehicles have a solid option in the JNC660 jump starter. Although this jump starter does not have phone or laptop charging features, it is the only jump starter on our list that will reliably jump start engines 6L and larger.
