Things to Consider Before Buying The Best Portable Jump Starters

Before you rush out and buy a jump starter you should know what things to consider about these mechanical devices. Many people base their purchases on the price of the item they are shopping for. When you are buying a jump starter you will want to move the price of the item to the low priority and make other features of the product top priority.

The main things you want to consider when buying one of these items is:

    • What size car can they provide an adequate boost to? You must consider what size vehicle you drive. If you drive a small or compact car you will be able to buy a jump starter that produces 350amps or 450 amps, but if you drive a vehicle with a big diesel engine or a large gas engine, then you will need a jump starter that can provide about 1000 amps.
    • You want to consider the safety features of the product before you buy. You want a jump starter that will not allow you to reverse polarity because reverse polarity is the main reason for most accidents that occur when a car battery is being jumped off. You also want to get a device that will not allow you to over-charge your battery, or allow you to provide too many volts to your battery. Both over-charging and increased voltage can damage the battery internally and reduce the lifespan of your battery.
    • You want to get a jump starter that will charge your electronic devices. When we connect our electronic devices to our automobiles we cause extra strain on the battery. You want a jump starter that can alleviate that strain for you, and one that could be used if you were camping or otherwise unable to charge your electronic devices, like during a power outage, or if you were stuck in a traffic jam.
    • Some jump starters also work as battery chargers. A jump start provides you the immediate power you need to crank a dead battery, but a charger slowly rechargers your battery. A battery charger restores the power to your battery so your engine can be cranked more than once without being connected to the boosting device.
    • Some jump starters also give you the ability to inflate tires. Having a device that will inflate car tires will prevent you from being stranded with a flat, or from doing damage to your wheels and rims because you drove on a tire that had inadequate air pressure. Having the proper air pressure in your tires also prevents some accidents, increases the life of your tires, and reduces the amount of fuel your engine consumes.
  • Some jump starters have flashlights that will allow you to be able to see to connect the unit in the dark, or that can be used as emergency flashers. Flashlights are important for everyone to carry in their vehicle, and having your flashlight be part of your jump start package means you will always know where that light is when you need it.

How Jump Starters Work

Jump starters are compact mechanical devices that allow you to provide an additional boost of power to your car battery. Often we leave the radio in the car playing, or we do not turn off the interior dome lights, and the result is our battery gets depleted of energy and the next time we go to crank our car our engine will fail to turn over. Cold weather conditions can also zap the strength from the average car battery.

A jump starter is designed to be a portable external battery that can provide a boost of power so your depleted battery has enough power to crank your engine. Once your engine is cranked your alternator should recharge your battery as you drive.

When using a jump starter you hook the cables that are connected to the device to the battery posts on your car battery. At the end of each cable is an alligator clamp that you use to grip the post of the battery. When you power the machine on a current will transfer the peak number of cranking amps the jump starter can produce through the cables and into your battery. This gives your battery an immediate surge of power so it can crank your engine.

The jump starter provides a one-time surge of power to your battery. Unless you have a jump starter that is also capable of working as a battery charger then you cannot plug the jump starter in for a long time and expect it to slowly restore a complete charge to your battery.

You must also be aware that if your battery terminals are corroded then the alligator clips will not make a good contact with the battery posts and this will stop the jump starter from being able to provide the full amount of peak amps that it is capable of producing.

Safety Tips

With any device, there are safety precautions you should take to ensure your safety and to prevent accidental damages. The following safety precautions apply to jump-start a car.

  • If you are jump-starting a car using another car then make certain both engines are in the off position while you are connecting the jumper cables.
  • It is imperative that the positive jumper cable is connected to the positive battery terminal, and that the negative jumper cable is connected to the negative battery post. If you connect positive to negative then you reverse the polarity going into the battery and this can cause a spark that can result in an engine fire, damaged cells in the battery, or can cause the battery to blow up or crack.
  • Make certain that you look at the battery before you connect the alligator clips. You are looking for obvious corrosion at the terminals of that battery and look for a cracked battery housing or the evidence of any fluids leaking from the battery.
  • Always read the user manuals of a jump starter prior to connecting the device to your battery.
  • Do not allow the positive and negative battery clamps to come into contact with each other while you are connecting or disconnecting the battery cables. You also want to make sure the ends of the jumper cables do not come into direct contact with parts of the vehicle.
  • Make sure that the booster cables are not making contact with a fan blade on the vehicle. Some fan motors can run even when the automobile engine is shut off.
  • Make certain that the automobile is in “park” for automatic transmissions and in “neutral” for standard transmissions, prior to connecting the booster cables to the battery.
  • You should wear safety goggles when you are using devices that provide a battery boost to your car battery.
  • Make sure that children are properly supervised when they around jump starters and running vehicle motors.

Q/A’s About Jump Starter

Can You Jump Start a Car in the Rain?

Many people ask if it is safe to jump-start their vehicle engines when it is raining. The answer is yes, it is completely safe to jump-start your vehicle while it is raining.

A vehicle battery is generally a 12-volt battery and that is a lot lower electrical voltage than what you would find at your residence. The 12-volt system will not cause sparks if it is exposed to the moisture from the rain so you can safely connect your jump starter and boost your battery without worrying about electrocution or sparks.

If you are on the side of a roadway you should turn on your emergency flashlight to the SOS mode so other motorists will be aware of your presence.

Oh! Dear…. I found this interesting and fun video in YouTube about jump starting in the rain:

Can You Charge a Battery With a Jump Starter?  

A car battery charger and a car jump starter are similar in appearance and performance but actually two separate devices. The jump starter is designed so that it will provide your battery a temporary surge of power so that it can be cranked. The jump starter is connected to your battery for a short period of time, usually no more than 3 to 5 minutes. Normally it is suggested that if your car battery is dead and you have to use your jump starter that you go immediately to your auto mechanic and let them evaluate your system to determine what caused your battery to be depleted of power.

The depletion of power may be due to a faulty battery, cold weather conditions, or a drain on the power of the battery while the alternator was not engaged to recharge the system. A faulty alternator may also cause your car battery to become depleted.

A car battery charger is designed to be connected to a battery just like the jump starts are, but the battery charger provides a lower amperage and is designed to remain connected to the battery until a complete recharge is done to the battery. Battery chargers are often used on vehicles that are not driven often enough to cause the alternator to recharge the battery.

Can You Jump Start a Car With a Bad Starter?

The definition of jump-starting a car is to connect a non-functioning car battery to another car battery, or to another power source like a jump start so that the non-functioning battery is given a boost of power that allows it to crank the vehicle.

When the starter on the car is malfunctioning you can run the battery down by continuously turning the key in an attempt to get the car engine to turn over, but an increase of power that you would get by connecting another battery to the car battery and boosting the battery power will not crank the car if the starter is not functioning.

If you drive a vehicle with a manual transmission you might be able to start the vehicle when the starter is malfunctioning by manually pushing the vehicle until it reaches a certain speed and then “popping” the clutch. You will usually have to get the vehicle rolling down an incline and then quickly jump in and pop the clutch.

If your starter is malfunctioning and will not turn your engine over, but does allow accessories like windshield wipers to operate then you can sometimes take a hammer, or blunt object like a hammer, and tap on the outside of the starter housing.

How many amps do you need to start a car?

The majority of small to mid-size automobiles can be cranked with between 300 and 500 amps. Remember that you must turn off your radio, windshield wipers, headlights, air conditioners, and accessories because each of these accessories makes the car need more amps to crank.

Larger vehicles, like the SUV’s, larger trucks, will need larger amounts of cranking amps. If you have a jump starter that can produce 1000 peak amps you will most likely be able to crank any non-commercial engine that you own. If you drive a commercial vehicle the cranking amps will be far more than 1000 peak amps.

Can I use a jump starter in any vehicle?

You can use a jump starter in the majority of all non-commercial vehicles. The commercial vehicles have engines that are so large the majority of jump starters simply do not have enough peak amps to provide the boost the batteries would need if they were depleted.

You must know what type of vehicle you have before you buy a jump starter because too few amps will not allow the machine to boost your battery, and if you have too many cranking amps being supplied by the jump starter you can damage your battery.

We advise you to buy a jump starter that has plenty of cranking amps but also has a safety feature that will not allow you to overcharge your battery, reverse the polarity of your battery, or provide too many volts to your battery.

Can my jump starter charge other devices?

This depends on the jump starter that you have. Some jump starters are designed to be used on 12-volt batteries, and some are designed to be used on 24-volt batteries, while other jump starters can be used on either the 12-volt batteries or the 24-volt batteries.

You should use a jump starter that stops you from over-charging or providing too much voltage to your battery if you plan to use the device on several different motorized items. If your jump starter has these safety features you can use it on motorcycles, lawn equipment batteries, watercraft batteries, marine batteries, tractor batteries, automobile batteries, ATV batteries, and more.

If you want to recharge or boost batteries like the 18650 battery that is rechargeable you must notice that these batteries need a charger that will slowly allow them to regain full battery power, and not a jump starter that gives one quick boost of power to the system.

The Lipo charger comes with an octopus so that it can be connected to many different types of battery terminals. Many people buy the Lip charger to keep proper chargers on their receiver battery packs connected to their nitro vehicles. The Lipo charger takes at least one hour to create a charge in a 3s Lipo 5000mAh 50c battery, and cannot be used as a jump starter, or on the typical automobile engine battery.

The type of battery charger you will use depends on the type of batteries you have and how the batteries are powered. The ranges from ion-lithium batteries like the ones that power your electronic devices, and the different battery types that power your vehicle.

Some batteries for vehicles are gel type batteries and some are acid lead batteries. The difference in the chargers designed to recharge these items is the voltage the charger supplies to the battery. This is why a voltmeter or a safety feature that does not allow your battery to receive too many volts is important to have on your jump starter.

Can jump starting damage my car?

Many people have heard about cars catching fire, batteries exploding, and other awful things happening to cars that were being jump started. The truth is that when you are jump-starting a car by using another vehicle you are putting both your safety and the safety of your car in danger. When you jump start in this method you can risk reversing the polarity and causing the battery to be permanently damaged, to blow up, or to spark and ignite your entire car. You can provide too much voltage to the battery by connecting your car battery to a much larger car battery, and that can do lasting damage.

If you are connecting one of the portable jump starters to your battery you are far safer and far less likely to do any damage to your car. These machines are designed to prevent accidents like reversed polarity or over-charging. Using the jump starters will allow you to safely crank your vehicle, without causing any damage. Just follow the manufacturer’s instructions.

Final note

The best jump starter is one that fits your price range, works on the size of the car engine you have, has safety features that prevent accidents, and is easy to use. The jump starters we mentioned in this article do all of these things and more.

It is a comforting feeling to know that should your car battery go dead; because you were listening to the radio; or the temperature outside depleted your battery; or your alternator stopped working, that you can give it a boost and crank your vehicle right up. It is also comforting to know that if your teenager takes the car out they will not run the battery down and be left stranded.

The security that a jump starter provides is simply priceless.
