The jump starter is as easy as putting it in a box. No need to wait for AAA. It does not depend on the jumper cables that are rarely used in your luggage. Don't mark a passing driver to let you jump. These cutting-edge jumper bags are easy to use and safe. They are also easy to store and maintain.


Here is all you need to know about portable jump starters and how to choose the best starter for you.



1. The power of the jump starter

The power of the jump starter is expressed as cold start current (CCA) or peak current (PA). Measuring CCA can tell you the expected value of the battery under the worst starting conditions imaginable. The CCA is determined by placing a fully charged new battery in a cold environment (0 degrees Fahrenheit) and measuring the amperage of discharge within 30 seconds.

The higher the value, the more powerful the starter. But this does not mean that you should choose the jumper package with the highest CCA and call it good.

There are two main factors to consider when determining the power level that is right for you.

2. Engine size
Small or small car batteries can jump through voltages as low as 150 CCA. Full-size trucks and SUVs require approximately 450 CCA. The size of the engine is important, but life is also a part of it.

3. Vehicle age
Assuming vehicles of similar size, the older the vehicle, the more amps are needed to jump. For example, the 20-year-old 8-cylinder engine pickup requires more current than the new amp to start.

This is due to improvements in engine design and newer starter motors. Generally, 400-500 CCA should start most passenger cars on the road.



5. Flashlight
Flashlights are common functions in larger and smaller jump starters. They will come in handy when you need to jump off the building at night or get into trouble for other reasons. Looking for high lumens.



6. Safety first

These are the batteries talking about, and the batteries contain electrical energy.

If not handled properly, it may cause danger. There is always a risk of injury, damage to the battery or starter and fire. Portable jump starters have multiple built-in safety features, which is a good thing.

Short circuit protection-prevents large currents from positive to negative clamping when accidentally contacted together
Overcurrent protection-prevents damage to the starter by preventing it from supplying current that exceeds the peak limit
Overload protection-when charging, prevent the current received by the jumper package from exceeding the current specified by the manufacturer
Overvoltage protection-During charging, prevent the voltage received by the jumper group from exceeding the voltage specified by the manufacturer
Overcharge protection – when the jump starter’s battery is fully charged, this will “float” to charge the device and prevent excessive voltage from being applied to the battery

Most jump starters have the above protection devices built in, but always check the listed safety functions to ensure safety. However, there must be an optional safety feature.
When you connect the cable clamp to the battery terminals, reverse polarity protection prevents damage to the battery.

Red is positive and black is negative. The positive cable is connected to the positive terminal, and the negative cable is connected to the negative terminal. Screw it up, you might kill the battery forever. You may also damage other parts of the electrical system.



The best portable jump starters have reverse polarity protection. If the cable is not connected properly, the warning light will come on. Some will even sound an alarm. The best part is that the circuit is not completed, so you have the opportunity to switch cables before driving.
Considering the size, power and safety, you may think that you are ready to buy. Get rid of this idea immediately. There is more content below.

7. Reliability

Many people think that higher prices mean higher quality, but not always. Each portable jump starter has something specific to look for. These will help you determine when the jump starter will work best.

8. Capacity
Capacity is the number of times you can jump start the car before you have to charge the jump starter. A device with a capacity of only 6000 mAh can provide enough capacity for several startups.

The good news is that all reputable manufacturers will build a lot of capacity in their equipment in order to make several starts. Don't catch up with capacity. Almost every bouncing starter you consider will have enough room.

9. Cold weather capability
If you have a warm climate throughout the year and don’t plan to drive to Minnesota, you don’t need to worry. However, if you live in a harsh winter place, choose a jumper that can withstand cold.

In cold weather, your car battery may lose up to 50% of its starting output. This means that you should expect the same performance loss in traditional jump boxes.

The excellent jump starter can jump the frozen battery when running at room temperature. If you live in a cold climate, it is also a good idea to buy an entry starter with a higher CCA.


10 Building Quality and Design
This is a good example of how price does not always mean high quality. You can buy a good-quality diving bag with cheap pliers that will not last long and perform poorly.

Look for clips that are soldered or screwed to the cable instead of crimping. The opening of the clamp should also be wide enough to fit any size of binding post and must not be bent or twisted.

In smaller jumper groups, the cable is an independent component that plugs into the main jumper unit. Some designed plugs are pulled directly from the circuit box. These may be difficult to carry and put in the engine compartment. The best-designed model puts some cables between the plug and the box to make operation easier.

Finally, be sure to exclude water and other contaminants from the connection port to help the device to be used for a long time. This means that the jumper cable connection port is usually covered due to its size. At least look for a tightly sealed lid. Ports that cover all ports are also better.

Design and material quality go hand in hand with functionality and accessories, so let's take a look at additional components that may interest you.

10. Features and accessories
The type of accessories will be very different between the traditional jumper box and the smaller lithium-ion jumper box. The following are examples of the more common accessories on each accessory.


USB charging
This feature mainly appears on small lithium-ion devices, but it does appear on some larger jump boxes. According to people who have tested, be sure to check the product reviews to understand the effect of this feature.

Multiple power supply/charging sockets
Some larger jump boxes also have multiple power sockets built in, such as traditional power sockets and 12-volt charger plugs. Versatility is the main factor in having these power supplies. In addition to quickly starting the car, you can also use the jump box for trailing or camping.

Some lithium-ion starters have special ports, such as 19V for charging laptops, or 12V for accessories (such as fans, electric blankets or lanterns).

Air compressor
When the TPMS indicator lights up and you are not near the gas station, it is good to know that your jump box has a built-in compressor. This means that your jumper box does have a built-in compressor.

This is a common function of large portable starters. If you do not live near a gas station or do not like to feed aircraft, it is worth having.


11. Guarantee
The gold standard for portable jump starters is a one-year warranty. Be wary of providing fewer manufacturers.
