Spirit A8 Car Jump Starter Review: How It Compares With Other Brands

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.

The Jump-N-Carry JNC660 is one of the most powerful jump starters on the market. The jump starter has a replaceable, valve-regulated lead-acid (VRLA) Rechargeable Clore PROFORMER battery designed for durability, and it peaks at 1700 amps or 425 cranking amps. This jump starter doubles as a “power bank” for your devices: You can use it to charge a variety of gadgets via its 12V charging outlet.

Weighing 18 pounds and with dimensions of 3 x 14.1 x 5.1 inches, the JNC660 is much bigger and heavier than “pocket” jump starters. On the front of this device, there is a voltmeter enabling easy viewing of the battery status.  The 12V outlet, which has automatic circuit protection, is also located at the front, near this starter’s status lights.

This jump starter has 42-inch cables leading to the jumper clamps. The JNC660 is a very powerful starter with enough power to start engines all the way up to those in 8L diesel vehicles.

Ease of Use

We found no difficulties at all in using this jump starter. After you verify that it is charged, all you need to do is to connect the clamps properly, wait a few moments, and the vehicle should start. We like the shape of the clamps because they are extra-easy to connect to car batteries.


The JNC660 is one of the most powerful jump starters you can get. This jump starter can only charge or power 12V devices. Unlike the Spirit A8 car jump starter, or the DBPOWER and GOOLOO units we also tested for this article, the JNC660 doesn’t have laptop or smartphone charging capabilities.

Design Quality

The JNC660 is a sturdy, heavy yet still portable jump starter with a hard plastic case. We like the fact that the battery, clamps, and other parts of the JNC660 are replaceable. This gives it a longer life than other jump starters.


The JCN660 jump starter is a reliable piece of equipment.  It is one of the few jump starters with a replaceable battery and clamps.

The jumper cable connection points are protected by silicone covers. The DBPOWER 600A jump starter comes with a big 18,000mAH lithium-ion battery.

The DBPOWER jump starter has more useful features than any other jump starter on our list. Besides jump starting your vehicle, it can charge laptops or comparable devices of three different voltages.

The DBPOWER Jump starter is very durable. Its 18,000mAh battery can jump start a car 30 times over, although we recommend that you recharge the battery when it falls beneath the 75% mark.

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.

Portable size

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.

Cable length

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.
