How Much Do a Jumper Pack to Crank a Car

Getting stranded with a dead car battery is never a good time, and it's pretty commonplace for drivers to carry a set of jumper cables as a backup. If you don't fall into that group of prepared motorists, you likely will be calling a tow truck or AAA to give you a jump, wait the hour while they come around, and feel helpless in the meantime. A newer and even more practical solution to dead batteries has been picking up steam, in the form of compact jump starter power packs.

These intuitive gadgets don't require another car to be present to deliver an electrical lifeline, but store power until called upon and discharge a jolt to your battery to get you back on the road in no time. The biggest benefit to this solution is the practicality of it all, even if you are alone and out of cell range without traditional jumper cables of your own, you can still resolve the problem yourself.

Most of the portable jump starters have one or types of output ports in addition to the jumper cables, so you can utilize the power to charge any electronics you may be using without needing to have 12V power from your car. The ultimate distress would be finding yourself stuck with a dead battery and a dead phone, without a way to get help. This gives the jump starters a more practical use over the traditional cables, since those only serve one purpose.

Since these are super useful tools, and massively popular with those in the know, we rounded up some of the most popular jump starters to do an apples to apples comparison so you know what to consider when shopping for one yourself.

Important specs for choosing a jump starter

When shopping around for a jump starter, there are a few different specs that are important to consider, and some that are not as important and can be a bit confusing.

Jump starter power

Peak power numbers (amps in this circumstance) are frequently plastered all over electronics because they are higher and look more appealing to consumers. The higher the peak amps, the better the jump starter right? Wrong. Audio components, generators, and jump starters (among other devices) all have their peak power listed, when in actuality the starting power/ rated power/cranking amps are the more important metric to consider.

A battery's cranking amps (CA) refer to the amount of power that your battery can discharge for 30 seconds at 32° F, which is designed to start your vehicle. If you live in cold climates, you will need to pay attention to a battery's cold cranking amps (CCA), which is the number of amps a battery can pump out for 30 seconds at 0° F without dropping below 7.2 Volts. This means that you will need a higher rating of starting or cranking amps for cold weather, but the bottom line is that the peak power is not as important as the starting power.

Size of the jump starter

Since these portable jump starters are designed to be kept in a vehicle in case of emergency, an important factor to consider might be the size of the unit, depending on your vehicle situation. Generally new model jump starters are very compact, and all the jump starters we have here are smaller than a standard sheet of printer paper, however if you have a motorcycle or ATV there is even less space to work with.

Additional jumper features

Aside from the main purpose of providing a quick power source for your auto battery, most portable jump starters also function as power banks. This power rating is separate from the peak/crank power rating, and gives you an idea of how many other electronics you can charge on-the-go, or how many times you can power up between recharges. Other features such as additional charging ports are common, and it's standard to have a built-in flashlight with three modes (on, blink, and rapid strobe).

Most of the jump starters we rounded up here come with the alligator clamps, charger for the unit, and a variety of other connectors for either charging mobile devices or powering 12V electronics.

Build quality

More often than not your jump starter won't be subjected to drops and roughhousing on a regular basis, but the construction quality is something to consider when shopping for a jump starter. Finding yourself in a situation with a busted jumper is just as bad as not having one at all.

From the start, all the ones that we gathered up here feel pretty substantial and well put together. The units themselves have a good weight to them, and didn't feel as if they would be susceptible to breakage from normal use.

Another note about the jump starter build quality concerns the actual battery itself. Most are Lithium-ion, and some have multiple levels of safety certification. The most popular of these are CE, RoHS, UL, FCC, and CE. This may or may not be important to you depending on your price range.

In no particular order, the following are our most popular jump starters with the specs laid out so you can do an easy comparison and find the right fit for your use.

More to know about jump starters

The one difference that stands out in the physical design of all the jump starters is that the Bolts, Annke, Antigravity, RAVPower, and AUTO-VOX all were designed to look like power banks. They have a rubberized finish (aside from AUTO-VOX and RAVPower's larger model which is plastic), all are pretty compact, have one LED in the flashlight, and many have multiple USB outlets.

The NOCO units weren't designed to look like power banks, and it would seem that their focus was more on the utility of jumping the vehicle over having multiple USB ports. The design is not nearly as compact, sleek, or flashy, and you certainly wouldn't be carrying one around in your pocket as strictly a mobile power backup. The NOCO cables are much thicker gauge, and the clamps have a more heavy-duty construction. Something to note about dead batteries in general is that below 25% charge most cannot be re-charged or jumped, and will require replacement.

Also, I should note that these were not tested for current, or in the field jumping a dead battery. The stats listed are based on manufacturer claims, but stay tuned for more of that testing in the future.
