Best Jump Starter Buying Guide & FAQ
What is a Jump Starter?
A jump starter is essentially a large battery that takes the place of another running vehicle when your vehicle’s battery goes flat and needs to be restarted. When a vehicle is running normally, a small electrical generator mounted on the engine (known as an alternator) charges the car battery and provides electricity to run accessories like the lights, heating/cooling systems, and radio. It also provides the power for the spark plugs to fire which in turn ignites the fuel/air mixture within the cylinders and allows the engine to turn over. When a battery goes flat or runs out of electricity, none of these processes can take place and the car cannot start.
Before the advent of the portable car battery charge packs, restarting the vehicle would require electrical power from the battery of another running vehicle whose battery was not flat. The best portable jump start batteries remove the need for this other vehicle as they provide the necessary electricity to get the car battery started again and therefore generating electricity from the alternator.
What to Look for When Buying a Jump Starter
When you’re looking for the best portable jump, it’s important to make sure that the pack you choose has the strength to get your truck or car battery started again. Bigger vehicles naturally require more power to turn over so it’s vital to ensure that the starter that you choose is up to the task of getting you moving again. In addition, you’ll want to make sure that you buy a quality battery pack that will hold its charge for a long period of time. After all, it would be terrible to have one with you in a time of need only to have it fail to work because its battery has gone flat. Many also come with standard safety protections to make sure that you don’t inadvertently damage your vehicle when trying to get it going again. Automotive electronics can be delicate and damaging them can lead to a bigger problem than just having a flat battery.
Something to consider when making your purchasing decision is the power output that the starter comes with. The power output of a jump pack comes down to the peak amperage, or current, delivered by the device and the watts.
The peak amperage of a jumper illustrates the maximum amount of power that a battery can discharge or give to a dead car battery. Many manufacturers put their peak amp ratings in their labels.
A higher peak amp rating is important because if the power output of the jump starter is not sufficient to initiate all of these mechanical processes, then you will not be able to jump your car.
The amp rating of the jump starter is an indicator of its true power output. You will also need to check its voltage so you’ll have an idea of its overall wattage. Given two 12V jump starters, for example, the jump starter with the 1000A rating will have more electrical power compared to the one with a 500A.
It is important to check your vehicle’s manual to know what amp rating is sufficient for your car.
Cranking Amp Rating
The cranking amp rating of a jump starter is a reflection of the amount of power that it can generate for about 30 seconds at a temperature of 32-degrees Fahrenheit or 0-degree Celsius while maintaining the minimum 1.2 volts per cell required on a standard 6-cell 12-volt battery. In layman’s terms, this is the amount of power that you will need to crank and start your car’s engine in almost any weather, except during the cold days of winter. For exceptionally hot climates, there are car batteries specifically designed for hot weather.
Now, if you live in an area where it’s like winter all year long you’ll need the ‘cold cranking amp’ rating. It’s like the ‘cranking amp’ except that it’s specifically rated for colder temperatures specifically at 0 degrees Fahrenheit or -17.8 degrees Celsius. Again, it should be able to maintain the minimum 7.2 volts for a standard 6-cell 12-volt battery. There are cold-weather car batteries specifically designed for this.
Voltage refers to the energy potential stored in an electrical system. This is what moves the electric current throughout the electrical circuit. When translated into a jump starter, it is what actually drives the electric current on the device towards the battery in your car.
Choosing the right voltage should be fairly easy since you only need to check your existing battery. Most light vehicles come with 12-volt batteries while heavy-duty ones like trucks, trailers, buses, and the like will usually have 24-volt batteries.
Most automotive experts recommend going for at least 12 feet when choosing jumper cables so that you have a bit of flexibility on reach.
As a rule, you should get a jump starter with jumper cables that are at least 8-gauge. If you can get a 6-gauge, better. Having 2-gauge is ideal although it can be a little more expensive. Generally speaking, the lower the number of the gauge, the wider is the diameter of the wire. The wider the diameter of the cable, the faster will you be able to start your car.
Price & Functionality
Good quality jumper cables alone can already set you back by as much as $60. There are, of course, newer and more portable jumper packs that are so compact they can easily slip into one’s pocket. Many of these can be had for about $50 or less. However, you need to ensure that they can deliver the right levels of power required by your car.
Professional-grade units can cost a few hundred dollars. Many of these come with high-capacitance jumper cables, batteries, and state-of-the-art power management modules complete with sophisticated electrical safety protections. These may not really be your idea of a compact and portable device as they can weigh up to 20 to 30 pounds. They do look like mini power generators.
You may also want to look at the functionality of the jump starter. Many portable devices today come with multipurpose functionality, fully capable of jumping a car while also serving as a mobile power bank. Some common features of the best portable jump kits include
- Ability to power up a variety of USB-enabled devices
- Inverters that will allow you to plug in your electronic appliance into an appropriate port in the device
- Built-in air compressor unit
- Included LED flashlight
Safety Tips When Using a Jump Starter
As with any piece of electrical equipment, caution needs to be exercised when using a jump starter. Be sure to thoroughly read through the instruction manual before using any unfamiliar jump starter. Also keep in mind these other standard safety tips:
- Check that the battery terminals and the connection clamps on your jump starter are in good condition, free of dirt and contaminants
- If possible, avoid jumping a car in the rain. As with any electronic equipment, keeping water away from your battery, wiring, and the jump starter itself is a good practice. Water conducts electricity and can make the jump process more dangerous than it needs to be.
- Avoid wearing loose clothing and dangling jewelry, and make sure that any long hair is tied up and away from the battery and jump starter clamps.
- Always read your vehicle owner’s manual.
- If you’re going to perform a donor-recipient jump start, always check the electrical power capacity or voltage capacity of the donor battery. It should match that of the recipient battery.
- Always unplug any electrical car accessories like mobile phone chargers and the like as the jumping process will send a power surge which can shorten these gadgets or accessories.
- Turn off everything in the car that runs on electricity such as the hazard lights, headlights, radios, and so on.
- Always use safety goggles as well as rubber gloves whenever you attempt to jump start your car.
- Always park both cars in either Neutral or Park. Also, engage both cars’ parking brakes. They should also be facing each other and as close as possible to each other to allow for the jumper cables to create the bridge. However, make sure that they don’t touch.
Jump Starter Terminology
In the previous section, we’ve been talking about a variety of technical stuff. And while we already did cover “amperes,” “cranking amps,” and “peak current” we’ll try to cover them again as well as a few other terms you might encounter in your quest for choosing the best jump starter for your car.
Most of the car jumper packs we have today come with built-in LED lights that have three different lighting modes. One of these modes is called the SOS mode. It sends out a steady stream of blinks or flashes to get the attention of anyone within visual range, in the case of an emergency. It’s like a lighthouse by the bay, guiding ships towards the shore on a stormy night. The difference, of course, is that the flashing SOS light is going to attract other motorists or emergency responders to your exact location.
Cranking amps is the amount of power discharged by the jump starter in 30 seconds at a temperature of 32-degrees Fahrenheit, enough to sustain a minimum of 7.2 volts in a standard 6-cell 12-volt battery or a minimum of 1.2 volts per cell. In layman’s terms, cranking amps is the power you need to start your car’s engine on any day except winter days.
If you live in places where the environmental temperature never falls below 32 degrees Fahrenheit, then you should always check the cranking amps of the jump starter. If you live in areas where the temperatures are lower than 32 degrees, then the cold cranking amps rating should be considered.
As the term implies, this is the maximum amount of electrical energy present inside a battery system. Current is measured in terms of amperes. So if you have a jump starter that says it has 1000 peak amps, then you know that it can only deliver a maximum of 1000 amperes.
Many of today’s home appliances are powered by lithium-ion batteries. Li-ion batteries last longer and hold a charge for a much longer time than other batteries. A typical Li-ion battery can lose about 5% of its charge on a monthly basis while a Ni-MH battery can experience as much as a 20 percent monthly loss.
You also don’t need to completely discharge a lithium-ion battery before you can recharge it, allowing you faster recharging times. The battery is also capable of handling more charge-discharge cycles.
However, it does come with a number of disadvantages. They only last for two to three years and the rate of degradation increases with heat. Another important consideration is that if the battery fails, it could possibly explode.
Joule is a unit of work or energy that is needed to generate a single watt of power every second. As such, 1 joule is equivalent to 1 watt-second. Translated into simple terms, you will need 1 joule to light up a 1-watt LED bulb for about 1 second.
Ampere or amp is the rate of energy flowing through an electrical system. More specifically, it is the electrical current present in your jump starter. It’s the rate of flow of current. Imagine water flowing through a closed-loop system. The rate of water flow is determined by how fast it moves. This is directly proportional to voltage and inversely proportional to resistance. Increasing the voltage will also increase the current while increasing the resistance will decrease the current.
LEDs are typically embedded into the design of jump starters for a variety of purposes. It can provide illumination for the LCD screen to make it more readable. It can also be used for indicator lights such as power, charge, and status lights. In some products, LEDs are also used in integrated flashlight systems. As long as there is a lighting mechanism in a jump starter you can expect it to be made of LED technology.
How to Safely Jump Start Your Vehicle
Jump starting your car shouldn’t really be that difficult since you’re essentially connecting cables from one power source to another — one that doesn’t have any power at all. In this section, we’ll go over how to use portable jump starters and as well as how to use the old donor-recipient manner.
Using jump starters
Using a dedicated portable charger for a car battery is pretty straightforward, regardless of the manufacturer of the device.
- If possible, park your vehicle on flat and stable ground. Engage the parking brakes and put the gear in the Neutral or Park position if driving an automatic. Turn off all electrical systems in your car.
- Double check your jump starter that it is fully charged or that it has plenty of charge left to deliver power to your car. Now, turn it off.
- Connect the red clamp to the positive end of your vehicle’s battery.
- Take the black clamp and clamp it on the negative end or terminal of the car battery. This is crucial. Black always goes to the negative terminal. Red always goes to the positive terminal. Think of it this way. Red is blood, which means life. Black is death. You won’t miss it.
- Check that the clamps are fully secure. Once done, you can turn on the jump starter and turn on the ignition of your car.
- Your engine should start. If not, let it rest for about two to three minutes before attempting to crank it again.
It is important to be mindful of the length of time that you are cranking your engine. You should not crank it for more than five seconds. The cranking amp of the jump starter is actually delivering a large amount of energy into your car’s system. It’s specifically designed to do so in relatively short bursts. Cranking your engine for longer than five seconds may risk overheating.
Once your engine has turned over, immediately turn off the jump starter. Remove first the black clamp before the red clamp. Keep your engine running to allow its battery to recharge.
The traditional method of jumping a vehicle entails another vehicle or a donor vehicle. The same principle applies, except that you will be dependent on the power supply coming from the battery of another vehicle.
Best Jump Starter FAQ:
Q: How many amps do you need to start a car?
This greatly depends on your vehicle’s engine size and how dead your battery is at the time of recharging. For most sedans, SUVs, light trucks, and minivans, you’ll probably need something in the neighborhood of 400-600 amps at the minimum. For larger trucks and commercial equipment, you’ll need much more.
Q: Can I use a jump starter on any vehicle?
Theoretically, yes. You can use a jump starter on any battery-powered vehicle, provided the jump starter is rated to be powerful enough for the intended vehicle. Be sure to double check your vehicle’s requirements against the jump starter’s power rating before hooking it up, just to be safe.
Q: How do I charge my jump starter?
The most common method for charging most jump starters is simply plugging them into a regular 120-volt AC household outlet. Some jump starters can also be recharged via your vehicle’s 12-volt cigarette lighter, or even with solar power or a USB interface.
Q: Do larger jump starters have more power?
Oftentimes, larger jump starters do have more power, but this isn’t a hard and fast rule. We’ve listed some very compact and portable jump starters with impressive power capabilities, as well as some larger, less powerful units in our list of product recommendations. So, always double check the label, and don’t judge a book by its cover if you’re looking for a certain amperage of peak power.
Q: How long should you jump a car for?
This depends on several factors, including the size of your engine, the power of your jump starter, how dead your battery is, and the temperature of the surrounding environment. Generally speaking, most batteries will need to be charged from 5-20 minutes in order to get enough juice to start from dead.
Q: Can my jump starter charge other devices?
Many of today’s jump starters are equipped with 12-volt DC, 120-volt AC, or USB charging ports that allow you to power a multitude of devices from personal electronics, air compressors, lamps, radios, and much more.
Q: Can you jump start a car in the rain?
A straightforward answer is yes, you can jump your car in the rain. If you don’t mind catching a cold or risk slipping and falling on the ground, then it is perfectly okay to jump start your vehicle even when there’s a downpour. If you’re worried about possible electrocution, your car’s electrical system only runs on 12 volts, unlike the electricity that we have in our homes that run on either 110 or 220 volts depending on which part of the world you live in. As long as you take the necessary precautions, you should be fine.
Q: Can jump starting damage my car?
Really the only ways that jump starting your car can cause damage are if you reverse the polarity of the jump starter and your car battery by hooking up the charging clamps in the wrong way, or if you use a jump starter that runs on a voltage system that’s not the same as your vehicle’s battery system.
Our Top Pick
Now that you’re well-versed in the ways of the jump starter, you can imagine why we chose the Clore Automotive Jump-N-Carry JNC660 1700 as our top pick. Not only is it offered at a reasonable price point, but it’s equipped with an impressive 425 cold start amps and 1,700 peak power amps to quickly and efficiently start most V8 powered vehicles. It’s also ruggedly and durably constructed to withstand some serious wear and tear.
For a more budget friendly, but still powerful option, consider the BUTURE Portable Car Jump Starter Kit. It packs a punch with 2,000 amps of peak power but is compact and portable enough to fit in your glove compartment. Plus, it comes with a surprisingly low price tag.
