Best Portable Jump Starters

Imagine this: You’re out on a job and about to fill up your rollers’ tanks when you realize that your water truck won’t start. You can’t sit around waiting for someone else on the job to come over and jump the truck. With a portable jump starter, this situation can be remedied in seconds.

New lithium-ion jump starter options provide an attractive alternative to traditional lead-acid batteries. They’re usually lighter and more compact, they’ll typically keep a charge for up to a year, they can be used multiple times before recharging, and they have long life spans. Some of them even come with USB ports to charge other devices, emergency lights and 12V power ports.

Essentially, a portable lithium-ion jump starter is a larger version of the portable batteries you might be using to charge your phone on the go. The difference is instead of 1000 to 3000 milliampere hours, or mAh, we’re talking 15,000 or even 30,000.

But there are tens of thousands of portable lithium-ion jump starter options available, and not every jump starter will work on the types of vehicles on a paving job. To ensure you get a battery pack that will work with a variety of equipment, there are a few things you should look for.

Experts recommend a power pack with at least 300 amps to start larger engines. You’ll also want to consider the number of mAh, which will give you an idea of the battery’s capacity, as well as the voltages supported by each battery. You might also consider benefits, like a light (useful to jump at night) or the ability to charge other devices.

The Key Functionality of Jump Starter You Need To Know

If you’re looking for a jump starter, so it’s important that you know what to look for and what key functionality they offer before plunking down your cash.

Why would you want one in the first place? The most obvious answer is that you are concerned about being left stranded in a lonely parking lot, at night, in the rain with a low battery incapable of starting your car. You could use jumper cables if you carry them and if you’re lucky enough to find someone left in the parking lot that is willing to let you use their vehicle’s battery for the jump start.

If this description approximates why you might want one, then please read on.

I have listed the key specifications you need to consider when purchasing a jump starter battery with an explanation and then the most common features also with explanation for each so you can compare apples to apples.

Let’s look first at the key specifications you need to consider when purchasing:

Jump Starter Battery Key Specifications

1. Battery Type

Your vehicle will most likely have a 12 volt battery but, it’s possible in the case of garden tractors and classic cars, that it might have a 6 volt battery. Be sure your jump starter matches your battery type.

2. Jump Starter Battery Power

As has been said, when it comes to a jump starter battery, it’s all about the battery’s power. The battery inside the unit needs to have enough peak and cranking amps to start your car in an emergency situation. The higher the peak amps, the more power the jump starter battery can feed in a hurry to your low battery to boost it for starting. For most applications, look for approximately 900 or more Peak Amps and 225 or more cranking amps. Pay attention to what type of battery is in your car and make sure you match the cranking amps accordingly.

Key Features

1. Easy Recharge

You will need to stay on top of the health of your device so that it’s ready when you need it. That means keeping it charged. Most have a built-in AC cord that can be used to recharge the device. Make sure the device you’re considering has an on-board method to recharge the battery.

2. Heavy Duty Insulated Clamps

Often emergency starting happens in bad weather and if the under hood of your car wasn’t dirty enough there could be additional dirt and build-up on the battery posts. To get through all that crud and make a good contact, you need heavy duty clamps. For the sake of safety, choose a unit with well-insulated clamps to prevent shocks.

3. Cable Length

Cable length determines how much flexibility you have in placing the jump starter battery while jump starting the car. Three foot long cables or longer should be considered the minimum.

4. Weight

Weight will be determined by the battery’s size and capacity. If jump starting is an infrequent occurrence for you, then consider a smaller size and weight unit. Weight is also determined by optional features. For instance if you want a small compressor built-in or if you want power outlets, these will add weight to the unit.

5. Warranty

Warranties vary greatly by manufacturer and the type of jump starter battery. Typical warranties run between 90 days up to 2 years. All other things being equal, a longer warranty may tip the balance in favor of one unit over another.

Optional Features

1. Power Outlets

Since this is a portable device, it can make a great traveling companion, not just for emergencies, but also, if properly equipped, as a temporary power source for all those electronic devices we carry with us. Power outlets can include AC outlets for video players and laptops as well as DC outlets like USB for mobile phones and MP3 players. Power outlets can be a highly desirable feature so consider this feature when choosing a unit.

2. Lights

If your car doesn’t have a light under the hood then jump starting in the dark could be difficult. Some units have built-in lights to help with this problem. Of course, just having an extra light in the car in case of emergencies can be very helpful.

3. Air Compressor

The ultimate portable emergency jump starter battery package would include an air compressor to inflate a tire in the event of a flat. If the tire is damaged, it might not be as useful.  However, if it just has a slow leak, the compressor may give you enough inflation to get to a safe place, such as at home or a tire repair store.

#How to AGA Portable Jump Starter? #

First, make sure your portable jump starter is fully charged.
Jump starters rely on a battery as their power source. As a result, they must be periodically recharged. Always recharge your portable jump starter/battery booster pack after each use and at least once every 6 months. These jump starter batteries will lose their charge more quickly if left in the car during hot and cold weather. We recommend charging your battery booster packs before going on a long trip.

Usually an indicator light on the jump starter tells you when a recharge is necessary. Simply insert the power adapter into an outlet and charge the battery until the light indicates a complete charge. (usually red/orange for charging and green for completed charge).

After your car is running again, remember that a jump is meant to restart the disabled vehicle, not to recharge the battery. It's a good idea to put the jumped battery on a battery charger, which you can buy as below:

A Special tool for Car Battery

Here's a special AGA power bank that can jump-start your car battery

A car battery dying in the middle of nowhere is one scenario no motorist relishes. Yes, there’s that Motolite hotline that you can call to deliver a new battery to wherever you are. But that's assuming you have cash or a credit card on hand. And what if your battery is just temporarily discharged?

While roaming inside the mall near our office, we discovered an interesting device inside the Handyman hardware store that can supposedly help you in case your battery fails--whether temporarily or permanently. It's called the AGA Power Jump, and it's essentially a large power bank that has special connections to jump-start your vehicle's battery.


Based on the video presentation being shown, using the AGA Power Jump is so simple that even those not mechanically inclined can use it. In case you hear that dreaded sputtering when you try to start your car, just connect the included special jumper cables to your Power Jump, attach said jumper cables to your car's battery, and go back inside your car and turn the ignition key.

On the days when your car battery works fine, the Power Jump works like your typical power bank that can charge smartphones and tablets. The included kit even has a Lightning connector for the latest iPhones and iPads.

Principle!!! Analysis of lithium ion battery protection circuit in Jump starter ---From AGA jump starter.

Now, seat heating, air conditioning, navigation, information entertainment, driving safety and other systems are designed to improve comfort and driving experience. From these systems, it is easy to understand the benefits of electronic systems powering various functions in the car. Now it's hard to imagine what happened just over 100 years ago when there were no electronic components in a gasoline-powered car. At the turn of the century, cars began to have hand cranks, headlights began to be illuminated with acetylene gas, and pedestrians could be prompted by bells. Nowadays, automobiles are becoming the junction of electronic systems, minimizing the use of mechanical systems, and becoming the largest and most expensive "digital tools" in people's lives.

As more and more mechanical systems are replaced by electronic systems, power consumption becomes more and more important. Whether the owner makes use of the car, there is a possibility that the car's battery power is not enough to cause the problem of not starting. So businessmen have developed an electronic product based on the demand for automotive power - automotive emergency start up power supply(Jump starter).

Let's talk about the safety of Jump starter today. Everyone knows that the core of jump starter is its built-in lithium-ion battery, and the characteristics of lithium-ion battery determine that it can not be overcharged, over discharge, over current, short circuit and ultra-high temperature charge and discharge, so the lithium-ion battery components will always follow a delicate protective plate and a current fuse. The protection function of lithium-ion batteries is usually accomplished by the protection circuit board and the current devices such as PTC. The protection board is composed of electronic circuits. The voltage of the battery and the current of the charging and discharging circuit are monitored accurately from - 40 85 C, and the current circuit is controlled in time. PTC stop the battery damage when the battery in the high temperature . Common lithium-ion battery protectors usually include control IC, MOS switches, resistors, capacitors and auxiliary devices FUSE, PTC, NTC, ID, memory, etc. The control IC controls the MOS switch on under all normal conditions, so that the battery cell and the external circuit on, and when the battery cells voltage or loop current exceeds the prescribed value, it immediately controls the MOS switch off to protect the safety of the battery cells.

Principle of protective plate for lithium ion battery

As shown in the figure, the protection circuit consists of two MOSFETs (V1, V2) and a control IC (N1) plus some resistance and capacitance elements. The control IC monitors the battery voltage and circuit current, and controls the gate of two MOSFETs. MOSFETs act as switches in the circuit, respectively controlling the conduction and shutdown of charging and discharging circuits. C3 is a delay capacitor. The circuit has the functions of overcharge protection, over discharge protection, over current protection and short circuit protection.

1. Overcharge protection

The lithium-ion batteries charge mode is constant -current/ constant -voltage charging. In the initial stage of charging, the voltage will rise to 4.2V (sometimes 4.1V, depending on the cathode material) for constant-current charging. Some batteries require constant-voltage charging until the current becomes smaller and smaller. If the charger circuit is out of control during the charging process, the battery voltage will continue to rise after the battery voltage exceeds 4.2V. When the battery voltage is charged to more than 4.3V, the chemical side effects of the battery will intensify, which will lead to battery damage or safety problems. In a battery with a protective circuit, when the control IC detects that the battery voltage reaches 4.28V (which is determined by the control IC, different IC has different values), its "CO" foot will change from high voltage to zero voltage, so that V2 will turn on and off, thus cutting off the charging circuit, so that the charger can not recharge the battery. It has over charge protection function. In this case, because of the existence of V2 with the body diode VD2, the battery can discharge the external load through the diode. There is a delay time between the detection of the battery voltage over 4.28V in the control IC and the signal of the switch-off V2. The delay time is determined by C3 and is usually set to about 1 second to avoid misjudgment due to interference.

2. Over discharge protection.

When the battery voltage drops to 2.5V, its capacity has been completely discharged. If the battery continues to discharge , it will cause permanent damage to the battery. When the control IC detects that the battery voltage is less than 2.3V (which is determined by the control IC, different IC has different values), the "DO" foot will change from high voltage to zero voltage, so that V1 will turn on and off, thus cutting off the discharge circuit, so that the battery can no longer discharge the load and play an over discharge. Protective effect. In this case, because of the existence of V1 with the body diode VD1, the charger can charge the battery through the diode. Because the voltage of the battery can not be reduced under over-discharge protection, the current consumption of the protection circuit is required to be very small. At this time, the control IC will enter a low-power state, and the power consumption of the whole protection circuit will be less than 0.1 mu A. There is also a time lag between the detection of battery voltage below 2.3 V in the control IC and the signal to turn off V1. The time lag is determined by C3 and is usually set to about 100 milliseconds to avoid misjudgment due to interference.

3. Over current protection

Because of the chemical characteristics of lithium-ion batteries, battery manufacturers have stipulated that the maximum discharge current should not exceed 2C (C = battery capacity / hour). When the discharge current exceeds 2C, the battery will cause permanent damage or safety problems. When the discharge current of the battery passes through two MOSFETs in series during normal discharge , a voltage will be generated at both ends of the MOSFET due to the conduction impedance of the MOSFET. The voltage value U = I * RDS * 2, RDS is the conduction impedance of a single MOSFET. The voltage value is detected by controlling the "V -" foot of the IC, if the load is different due to some reason. Often, when the loop current is large enough to make U > 0.1V (the value is determined by the control IC, different IC has different values), its "DO" foot will be changed from high voltage to zero voltage, so that V1 from turn on to turn off, thus cutting off the discharge circuit, so that the current in the loop is zero, playing an over current protection role. There is also a time delay between the over current detected by the control IC and the V1 signal being turned off. The time delay is determined by C3, usually about 13 milliseconds, to avoid misjudgment due to interference. In the above control process, the magnitude of the over current detection value depends not only on the control value of the control IC, but also on the conduction impedance of the MOSFET. The larger the conduction impedance of the MOSFET, the smaller the over current protection value of the same control IC.

4. Short circuit protection

In the process of discharge, if the circuit current is large enough to make U > 0.9V (the value is determined by the control IC, different IC has different values), the control IC will judge the load short circuit, and its "DO" foot will quickly change from high voltage to zero voltage, so that V1 from conduction to turn off, thus cutting off the discharge circuit and playing a short circuit protection. Use. The delay time of short circuit protection is very short, usually less than 7 microseconds. Its working principle is similar to over current protection, but the judgment method is different, and the protection delay time is also different.

The working principle of a single lithium-ion battery protection circuit is described in detail above. The protection principle of multiple series lithium-ion batteries is similar to that of single lithium-ion batteries. In addition to the control IC, there is an important element in the circuit, namely, MOSFET, which plays a switch role in the circuit. Because it is directly connected between the battery and the external load, its conduction impedance has an impact on the performance of the battery. The load carrying capacity is also strong, and it consumes less power when discharging.
