Features to Consider in Good Jump Starters
What is a Jump Starter?
A jump starter is a large portable battery that is equipped with a pair of jumper cables. When your car battery goes flat you can use the jump starter to charge the car battery without the use of another vehicle’s battery.
An alternator which is a small electrical generator mounted on the engine charges a car’s battery. It provides electricity to run electronic accessories such as the lights, car radio and A/C systems. The alternator also provides enough power for the engine’s spark plugs to fire up.
The spark plugs ignite the fuel and air mixture within the system’s cylinders which allows the engine to work. When the car battery is flat, the entire system in your car won’t work because none of the processes will operate without the electricity of the alternator.
Before the invention of portable jump starters, you’d need the assistance of a vehicle with a working battery in order to charge the flat battery in your car. With jump starters, you don’t need an additional vehicle’s working battery.
The jump starters provide enough electricity to charge a flat battery by using the electricity of the alternator.
There are other useful features that some jump starters have such as:
- SOS signal
- Charging station for SmartPhones
- Onboard air compressors
Features to Look For
Before buying a jump starter it’s vitally important you check that it provides enough power to jump start your car, quickly and easily. Bigger engines in trucks, vans and motor homes generally need a more powerful device.
You also need to make sure that the jump starter is a quality made product. The device will need to hold its charging life over a long period of time. After all, you don’t want to be stranded with a flat car battery and a jump starter that’s also flat.
It’s also advised that you opt for a jump starter that has safety precautions. The safety is to ensure you don’t damage your car while you’re jump starting it. The electronics in a vehicle are delicate and damaging the systems can lead to bigger & more expensive car problems.
In order to purchase the correct jump starter for your vehicle, there are a few features you should take into account. By understanding these key features you may even be able to find a device that has additional useful purposes.
The length of the cable depends on your preference. If you prefer to have your jump starter resting on the ground naturally you’ll need a device with longer cables. But if you prefer a device without the hassle of long cables you may want to opt for a jump starter with shorter lines.
Most experts recommend going for jump starters with cables that are 12ft in length. What’s more important is the wiring inside the cables. Cables with thinner wiring won’t produce charging power fast enough. It will take longer to charge your car battery.
You should purchase a jump starter with cables that have at least an 8 gauge; although having a 2 gauge is ideal but can be quite pricey. Basically, the wider the cables are the quicker the jump starter will charge your battery.
The power output is represented by either the watts or peak amperage of the device. The peak amperage of a jump starter is the maximum power it can produce to recharge a flat battery. Many jump starters have labels with their peak amp ratings on them.
You will need a jump starter that has the highest amp rating. The reason for this is because there are many components in a vehicle that needs to be powered up. If the power output of the jump starter isn’t sufficient it won’t be able to jump start all the mechanisms in your car.
Another aspect you should look for is the voltage which will give you the wattage produced by the jump starters. An electrical system is measured by watts. So if you want more electrical power you’ll need to either increase the current or the voltage.
The voltage is usually standard so you’ll either get a 12V or a 24V device. To check the correct power outage of your vehicle, you’ll need to refer to your owner’s manual. You can check the electrical section to see how much power you’ll need to start up your engine.
It’s also advised that you check the specs of your battery so that you purchase a jump starter with the correct power outage.
Cranking Amp Rating
This is the amount of power you need to crank and start up your engine in any type of weather conditions. If you live in regions with colder climates with temperatures below zero you’ll need a cold crank amp rating.
In colder climates, you’ll need an extra powerful device to get your engine and crankshaft up & running again. When you purchase a jump starter check the crank amp rating and the cold crank amp rating. It will give you a better idea of the jump starter’s ability to start your engine.

Guide to Buying the Best Jump Starters
Jump Starter Specs
In order to find the correct jump starter for your car, you’ll need to check your owner’s manual. In the manual it will tell you all you need to know about the specifications of your vehicle. The jump starter needs to match the requirements of your car.
It’s vital to purchase the correct jump starter for your car. Purchasing a jump starter that’s not powerful enough to start up your engine will leave you stranded. Jump starters with too much power outputs can also damage your car.
Rather check your owner’s manual or consult a professional mechanic to see what specifications you need.
Jump Starter Terminology
Most of the jump starters manufactured today have integrated LED lights with three different lighting modes. One of the lighting modes has an SOS signal that flashes with a steady set of blinks. The flashes are to signal anyone in visual range.
The SOS signal is designed to get the attention of other motorists on the road to stop and help you when you’re stuck with a broken down vehicle.
Cranking amps is the amount of power produced by the jump starter in 30 seconds at temperatures of 32°F. It should be enough to sustain 7.2V in a standard 12V battery. As mentioned before it’s the power you need to power up your engine in any weather conditions.
You won’t need a cold cranking amp if you stay in regions with temperatures mostly above 32°F. But if you stay in colder regions you should consider purchasing a jump starter with a cold cranking amp.
A cold cranking amp is designed to turn your engine in climates below zero. Jump starters that have a cold cranking amp feature are more powerful than standard cranking amps. In colder climates, the oil in your car is a lot thicker. You need a powerful cranking amp to warm up the oil to get your engine to turn.
The peak current is the maximum amount of electrical energy present inside a battery. Current is measured in amperes. For example, if you have a jump starter with 1000 peak amps it can only deliver 1000A.
Lithium-ion batteries are capable of storing higher densities of energy in compact devices. Batteries made with lithium ion can store up to 150 watt-hours of electrical energy per kilogram of battery. The advantages of lithium-ion batteries are as follows:
- They’re more durable than other batteries such as nickel metal
- Faster recharging times
- Handles more charge and discharge cycles
A joule is a unit of energy needed to generate a single watt of power every second. For example, one joule is an equivalent of one watt per second. This essentially means you will need 1J to power a 1W light bulb for one second.
LEDs (light emitting diodes) are semiconductor devices that are typically integrated into most jump starters. The LED light can provide illumination for the LCD screen when there’s insufficient lighting to make it more readable.
They can also be indicator lights to inform you if the battery on your device is low and give you the status of your charging. LED lights can also be used as a flashlight and to provide an SOS signal in times of trouble
Jump starters usually come with safety instructions that you can follow. But it’s always best to take extra precautions when working with jump starters. Here are five safety tips you should consider when using your jump starter.
- If there are contaminents on the terminals and on the connection clamps it could hinder the process of getting your car moving again. Ensure that the connection clamps and the battery terminals are free from dirt & they’re in excellent working condition.
- As with any electronic device, water will act as a conductor and can make the process of jump starting your car extremely dangerous. It’s advised to avoid jump starting your car in the rain. You should always keep water away from your car battery, the wiring and the jump starters as an added safety measure.
- You should always wear protective covers on your hands when working with jump starters. Having a pair of gloves in your car at all times will come in handy if you find yourself stuck on the side of the road.
- Always refer to your owner’s manual to check your car’s specifications before you use a jump starter. Some automatic ignition systems can’t be jump started. To avoid damaging your car you should check everything in your owner’s manual first before purchasing your jump starter.
- Unplug all electrical accessories that may be connected to your car such as mobile phones. The jump starter can send an electrical surge through the vehicle which may damage any electrical device plugged into your car.
How to Perform a Jump Start
Jump starting your car is actually really easy because you’re essentially connecting cables from one power source to produce energy to a flat battery. If you’re still not sure what to do, follow these easy steps:
- Park your car on a flat surface or stable ground. Always put your car in neutral.
- Switch your jump starter on simply to check if it has enough charge to start up your vehicle. Once you’ve checked you can switch the device off.
- Connect the red clamp to the positive red terminal on your battery. Take the black clamp and connect it to the negative black terminal on your battery.
- Ensure that the clamps are secure and won’t unclip at any stage of the process.
- Turn on the jump starter and then turn on the ignition of your car.
- TThe cranking amp comes in handy here if your car battery isn’t being charged enough. Wait a few minutes and if there’s still no power, crank the amps up a little bit more.
- Be mindful of how much time you spend on cranking. You shouldn’t crank up the device for more than five seconds as this could overheat your car.
- Once your engine has turned you can turn the jump starter off.
- Remove the black clamp first before removing the red one off of the battery terminals.
- Turn your car on and allow the engine to run to allow the battery in your car to charge up before you drive off.
The donor-recipient way of jump starting a car is an alternative but it’s not ideal as you’ll need another person willing to stop to help you out. Sometimes this doesn’t happen so you’ll be left stranded.
