Sometimes problems with engine can occur even in a new car. It can also happen because your battery is old and its power may not be sufficient at some point. This kind of nasty surprises can be easily fixed by jumper cables or a good jump starter. Read the review to pick the best one for your car!
Besides the type, size, and weight, additional options matter as well. Defining the best jump starter is not a task for techies only but for any prudent car driver. In the current review, there are three general types of these devices outlined that differ by size, mobility, and battery type:

  • Full-sized jump starters — most models of this type are portable while featuring non-lithium ion batteries. Their primary advantage is a large output. It is especially important for large cars and the ones having high-capacity engines. Should you own a large diesel truck or a minivan, such a device would make the best car jump starter for you. Often, they possess a built-in compressor along. They are great to keep in your garage for emergency start, while their size and weight do not inspire for carrying them along. Besides, such jump starters need to be recharged regularly (in average, every 30 days).
  • Portable lithium-ion jump starters — these devices are based on the lightweight lithium-ion batteries (just like your smartphone) and belong to the portable type. Their size and weight make them a worthy thing at the on-road emergencies. Not being in use, they hold the capacity well and do not require regular charging. However, their output is less than in full-sized devices. Most of the best lithium ion jump starters are enough for cranking up the gas engines of up to five liters and the diesel ones of up to four liters capacity. Yet, there are super-powerful models available that can be used for periodic jump starting of 5-8 liter gas engines. They can also ignite the 3-4 liter diesel engines in next to no time.
  • Compact non-lithium-ion jump starters — these starters tend to be a very smart choice for those who needs a small and sustainable device. Just like lithium-ion ones they are portable and handy, so you should consider buying them if you have a small or medium-sized car. Though, if you’ve got a huge truck with unreliable battery in your garage, it would be much better to think about buying a full-sized jumper.

I have tested a lot of different jump starters and they were not too good in most cases. However, finally I managed to gather the best ones in this article.

Essential Factors to Consider

During the operation with the Lithium ion portable jump starter. It is necessary to consider not only how long the tool will work, but also how much it will suffice. Security and warranty are really important factor, but often buyers don’t pay much attention to it. However, the warranty will save your money if the accident occurs. To use the Lithium-ion portable jump starter you need to have a basic understanding of where the black and red poles are located on the battery and how to connect the device. And you have to remember that the higher the quality — the less probability of breakage of any part. Let’s consider more in detail each of the factors:

Durability: The Lithium-ion portable jump starter must work during the long time. Also, make sure it is made of frost-resistant materials, for example, if you store the device in a car in winter.

Safety: An overload protection is a must.

Starting power: The most important factor is the power that the Lithium-ion portable jump starter can give your engine. As a rule, the larger the volume of your engine, the more energy you need to run it, so you need to consider it when buying a Lithium-ion portable jump starter. Also, an important factor to consider: the amount of power required depends on the state of the battery and characteristics your car engine.

Clamps, cables, and build quality: All these elements have the following characteristics: unwinding or rupture since a certain number of manufacturers use cheap materials. The qualitative set of these elements provides a reliable connection on any battery element, without any twisting and bending. Also, you need to look at the power ports, they must be protected from dust and moisture, they should be tightly fixed. Since the Lithium-ion portable jump starter is a device developed to work near oil engines in all weather conditions, we clearly believe that these relatively small elements should be reliable and of high quality to guaranree the durability of your devices.

Built-in Charger: allows you to control the charge of the device, as well as get the device without recharging for a certain time.

USB Outputs: It is a useful feature that lets you recharge batteries of the portable devices such as cameras, laptops, tablets, and mobile phones.

How to charge a micro-portable jump starter booster pack

Most of best lithium-ion jump starters will have a 110/240V adapter that you can connect while charging to the device. The full charge of the lithium-ion jump starter will take several hours. After charging is completed, it’s worth taking off the charger to avoid recharging. Another option for charging the lithium jump starter is the presence of a micro-USB port, which means that you can replace the charger with a charger for your phone. However, such a charge will take longer than the standard one. It is also worth thinking about reloading. Excessive charging of the device reduces service life. As a conclusion, we can say that if you often recharge your device, it will damage the battery and eventually the device may fail. You need to fully charge and turn off the charge.

How many amps do I need a peak jump starter?

To get the maximum possible current strength, you need to find the true mileage rating (mAh) for your device’s battery. In order to check it, you will have to open the lithium-ion jump starter to see the battery specifications or to test the load. Necessary:

  • Open lithium ion jump starter
  • Cut lithium starter battery

Thus, the power Ohm Power = Volt x Ampere or P = VI

What is peak & Cranking Amps?

The process of choosing a lithium ion jump starter may be difficult for a simple user who does not know anything about these products. Buying a lithium ion jump starter, you can get confused, as manufacturers often have no sequencing in the marking of devices. They indicate in the technical characteristics of their devices only some amplifiers, idle amplifiers, some mAg. Some manufacturers even use Joules to make you even more confusing. What is the difference? We have prepared for you a small list of terminology to make you more focused on these complex definitions.

Peak Amps is a fairly simple definition that is characterized by the fact that the maximum power is estimated in order to impress, how much power is needed to charge the battery, and we suggest always refer to the boomers if this power is not enough amps.

Cranking Amps (CA) is a definition that contains the amount of power that your device battery can discharge for 30 seconds at 32 °F (0 °C). In simple terms, this is the power that is needed to start your car engine in any weather.

Cold Cranking Amps (CCA) – this definition refers to the number of amplifiers that the battery can eject for 30 seconds at 0 °F without dropping to 7.2 volts. It is difficult to start the engine in cold frosty weather thanks to a layer of thick oil and increase the resistance of internal parts in the engine – this is why the batteries are rated CA and CCA.

mAh – Milliampere hour (mAh) is 1000 times per hour of an amp (AG).

Both measurements are used to describe the battery charge, that is, how long it takes to charge the battery, and how long it will last before your battery needs recharging. Summing up, we can say that the best amplifier ratings show the real power to start the battery. The 500 CCA device rating has the ability to run virtually any car with an engine and with a battery that does not have a charge at all. So if you need to charge several vehicles, be sure that you have enough lithium jump starters for everyone. Just make sure its power is enough to start the car. No need to worry about overloading e with large engine volumes. If your battery is very weak, then this type of lithium battery jump starter is right for you.

How much voltage does it take to start a car?

Fully working and charged car batteries should measure 12.6 volts or higher. If the engine is running, this measurement should be from 13.7 to 14.7 volts. If you do not have a device such as a multimeter on hand, in order to find out about the voltage of the battery, you can independently carry out a test on the electric system of your car, starting the engine and turning on the lights. If the lights shine with a faint light, this is the reason why the light sources are turned off by the battery and the generator is not charged. If the illumination gets brighter when your engine is running, this may mean that the alternator generates some current, but this current may not be enough for an engine in a standby mode to keep the battery charged properly. If the headlights have the normal and desired brightness and do not change their intensity for a certain time when the engine is rotating, the charging system most likely works fine. If you have problems with the battery system, you should check if the battery is charged and if it works properly under different conditions.

Can you charge a battery with a jump starter?

They are also called accumulators, chargers, and portable batteries. However, you need to know – jump starter is not a charge for the battery. Jump Starter can be operated anywhere. They often act as a “replaceable battery” to start a car. By definition, Jump Starters is a portable power supply of 12 volts, because it depends on the compact 12-volt internal battery as a power source. Although battery jump box is commonly used for vehicles, they can also be used as a portable power supply for miniature 12V DC accessories. Since Jump Starters depend on the internal battery as a power source, they must be recharged after each use and application, it should occur periodically to leave the battery charge. The battery charger is part of every Jump Starter that’s on the market. To charge it, you need to connect your device to a standard 110 V AC outlet. Charging typically lasts from 10 to 36 hours, depending on the state of discharge of the battery. The charge indicator shows the need for charging. The generator ensures recharging of the car battery if it is operating in proper working order. Some Jump Starters offer you additional features such as air compressors and faulty light detectors, or a built-in power inverter. The power inverter converts the 12 Volt Jump Starter current to 110 watts of AC power, allowing you to work with 110-volt power tools, bulbs or other devices. Carefully read the operating instructions of the device before using any electrical appliance!
