A jump starter is one of those things you buy while hoping you'll never have to use it. However, that doesn't mean you should get an inferior model. On the contrary, since you will probably only be using a jump starter to get out of an unpleasant or potentially dangerous situation, you need it to be 100% reliable.
A jump starter must be strong enough to crank the engine of the largest vehicle you own (or may own in the future). A variety of useful features may come in handy in a number of situations.

There are three ways to get juice into a flat battery:
So, we know what a jump starter does, but why are there so many to choose from? In essence, there are two reasons. The smaller the vehicle, the less current the jump starter has to supply. That leads to models with a wide variety of different power levels. This is fine because not everyone needs to start a V8 pickup.
Notably, manufacturers try to tempt you with a variety of extras such as control technology, built-in safety features, and a host of useful (and not-so-useful) options. These elements impact performance and price, so let's look at each in turn.
A jump starter must supply sufficient current (measured in amps) to get the starter motor cranking over. In turn, that fires the engine.
The jump starter feeds current through the battery, temporarily taking its place. As soon as the vehicle is running, the jump starter is disconnected and, if all is working properly, the vehicle begins charging its own battery.
Inside the jump starter is one of two battery types: lead-acid (the same kind as in your vehicle) or lithium (the kind you would usually associate with power tools).
Lead-acid versions have been around for decades. They are proven, effective, reliable and durable. The downside is that, from 15 to 30 pounds, they're bulky and heavy.
Lithium versions are much more compact; many would fit in a glove box. They weigh a couple of pounds or less. They also have smart microprocessor control, so they not only start your car, but they can also charge your phone, tablet or laptop. The drawback of lithium models is their lower performance. Though high-performance models are becoming more widely available, they tend to cost more.
With the exception of smaller models (used to start garden tractors and that kind of thing), the battery inside a jump starter is the same voltage as your vehicle: 12 volts. More important, however, is the current it supplies in amps.
The motor in the average family car needs far fewer amps to turn it over than the motor in a sports car or big SUV. If you've ever bought batteries for different vehicles, you probably know that some need a higher ampere-hour (Ah) rating than others. Therefore, if you have a small car, you don't need a big, expensive jump starter. On the other hand, if you've got a rumbling V8, then a cheap, low-output jump starter isn't going to make it hiccup, let alone run.
If you can find cranking amp figures, the following is a useful guide, albeit approximate:
For gas engines, you’ll need:
For diesel engines, you’ll need:
Peak amps may be the only figure you can compare across several manufacturers.
Look for 600 to 1,000 amps from a lithium-based jump starter and 1,000 amps or more from a lead-acid model.
A lead-acid jump starter like the Stanley J5C09D, being larger, has room for features that wouldn't fit in the compact case of a lithium model. You might see the following features in a lead-acid jump starter:
The compact size of lithium jump starters doesn't allow for 120-volt outlets. Instead, this type of jump starter, such as the GOOLOO GT4000S model, concentrates on providing power for your electronic devices. You might see the following features in a lithium jump starter:
Bear in mind that the more features you use, the faster you'll drain your jump starter. Though most provide excellent performance and multiple vehicle starts between charges, this product is basically a battery in a case, not a portable generator.
A. There are three general price points you will encounter when shopping for a jump starter. For $100 or less, you can expect to find models that would be best for smaller vehicles of 4 or 6 cylinders. On our top five list, the NEXPOW 12V Jump Starter Pack and AstroAI S8 Car Jump Starter are good choices in this price range. Between $100 and $150, you will find jump starters such as the Clore Automotive Jump-N-Carry and the NOCO Boost Plus GB40 that can handle any vehicle. These products will be of high quality, offer sufficient features and be versatile enough to handle nearly any power situation you encounter.
If you have no concerns about budget, it is possible to spend over $150 and get a jump starter with all the bells, whistles and safety features possible. Just make sure that what you’re getting is worth the higher price tag. Our top pick, NOCO's Boost HD GB70, fits this criteria.
A. It's not really a question of which is better; it's which is most suitable for you. Lithium jump starters are small enough to keep in a glove box, but many lack the power to start big motors. Traditional jump starters pack more punch, but they are a lot larger and heavier.
A. It depends on the model. Some arrive fully charged; others need up to 24 hours to charge.
A. Peak amps denote the maximum current available. Cranking amps reflect the current available at 32 degrees Fahrenheit. It must be supplied for 30 seconds at 7.2 volts minimum. Cold-cranking amps reflect the current available at 0 degrees Fahrenheit. Again, it must be supplied for 30 seconds at 7.2 volts minimum. The cold makes engines more difficult to start, so more current is needed.
There is no direct conversion, but a jump starter with peak amps of 1,500 might only produce 400 cranking amps, which is roughly 320 cold-cranking amps. If you can compare CCA ratings, that's when the jump starter is working hardest, but makers often don't give figures. The peak amps figure is a reasonable alternative.
