NOCO Boost XL

Compact and Versatile

This small yet quite handy appliance will prove to be an essential piece of car-care equipment, especially if you ever find yourself in a situation when your vehicle simply won’t start. But what makes it stand out besides its high portability? To answer this question, we should first take a closer look at the specifications of the device. So, let’s begin.

Unlike the majority of conventional automobile jump starters, this model from NOCO features a built-in Lithium-ion battery, which allows utilising it in a number of ways, aside from its main purpose.

Amperage-wise, the NOCO Boost XL can deliver up to 1500 A to a flat automobile battery without breaking a sweat. Depending on the output interface, the amperage varies allowing you to utilise the jump starter as a mini power bank, which will definitely come in handy during long road trips where outlet access is limited. The maximum voltage output, on the other hand, is 12 V, making the battery charger an equally great option for big and small cars alike, be it a utility truck or a simple city hatchback.

The clamps, as well as the high amperage output, make this particular jump starter model suitable for both petrol and diesel cars. To be more specific, this model can accommodate vehicles with petrol engines of up to 7.0 litres, and diesel ones with the displacement of up to 4.5 litres.

Charge Batteries, Anytime, Anywhere

When it comes to the safety systems implemented in this model, it features a patented Ultra-safe spark-proof protection that won’t create any sparks in case you accidentally connect the clamps to one another while the device is on. Likewise, Boost XL features standard protection circuits including reverse polarity protection, as well as basic short-circuit safety.

Other special features include a USB output that can be used to recharge other USB-powered devices and a powerful road LED flashlight. While the former is pretty much self-explanatory, the built-in flashlight has a brightness of 200 lumens, which is quite impressive as for such a small device. Once it’s turned to full power, it can work as an effective road torch, as well as a means to guide you through the inner parts of your vehicle in a poorly-lit environment.

Wrapping things up, the Boost XL from NOCO is an excellent jump starter for pretty much any car that has a battery under its bonnet. Nimble, effective, and highly convenient to use, it is by far one of the top picks for the role of a road battery revitalizer.

CTEK MXS 5.0

A General Purpose Charger for Any Battery

While jump starters are considered universal devices for starting petrol engines quickly, nothing can really compare to the versatility of stationary models. But how do you pick the one that can work with various types of engines? Fortunately, this model from CTEK is, perhaps, the most versatile of them all.

First things first, the stationary car battery chargers don’t have a built-in battery, and the MXS 5.0 is not an exception to the rule. While its design takes the portability aspect out of the question, that’s where the fun begins.

The package includes a set of different clamps that can accommodate virtually any vehicle that runs on fuel, including car, truck, and motorcycle batteries. The first set of clamps are your regular car battery clamps that connect to the standard 12 V Lead-Acid models. The other two, however, are more suitable for smaller battery variants, including those with two-pins terminals, and smaller, battery terminal connectors.

While portable models need to be charged in advance, the stationary ones can work straight away as soon as you plug them into a power socket. The only thing you absolutely need to do, though, is to pick a required charging mode before you connect the clamps to a battery. Once set, the device will charge the battery in a matter of hours, or, alternatively, will allow jump-starting your vehicle in under a couple of minutes.

Review of CTEK MXS 5.0 Fully Automatic Battery Charger

Protecting Your Battery With Ease

As for other convenience features and quality-of-life improvements, using this model from CTEK allows prolonging the service life of the battery up to 3 times, which is not a small feat, considering how fast some batteries can become inoperable using simple charging adapters.

Alternatively, more accessories from CTEK are optionally available, so, if you want to purchase a protective bumper or a longer power cord, you can ensure that the device will work flawlessly by ordering one.

Last but not least, unlike many other models widely available on the market, the MXS 5.0 comes with an impressive, 5-year warranty on all components listed in the kit, which is a big plus in our book.

All in all, using a stationary jump starter is a perfect way to charge flat batteries of your vehicle in case you don’t have an adapter in your garage. However, if you own more than one vehicle with different batteries, this model from CTEK will be an excellent product to consider. Simple and easy to use and maintain, it is a cost-efficient charger that will not only allow you to start your vehicle but also won’t harm the power cells of the battery itself.

NOCO Genius

Charge It How You Want

The NOCO Genius Boost Plus is a great example of a portable car jump starter that you can put inside your bag or even in a pocket. Since the device has a relatively small size compared to other jumper models, you can store it almost anywhere as well - in your garage or even inside the glove compartment of your car.

When it comes to charging the internal battery, you can do it in two ways that will be convenient for both home and outdoor use. The gadget’s design features both 12 V and 5 V micro USB inputs so you can easily charge it from your car’s cigarette lighter, power socket, or from any USB-powered device.

Moving on, let’s take a closer look at the convenient features that this model has no shortage of. The Genius Boost Plus incorporates two built-in LED lights that will highlight everything you need even in a pitch dark environment. On top of the regular flashlight functions, the LED lights can be turned to SOS mode that will create a strobe light visible from miles away. Suffice it to say, this feature will prove to be particularly useful in all kinds of emergency scenarios.

Since you can charge the device by using both USB and car lighter inputs, the user’s manual will tell you that the best way to do so is utilise the latter method. For the most part, it is because the USB will only charge up the battery to 75% due to the limitations in voltage output, compared to the lighter charger.

Review of NOCO Genius Jump Starter

Tiny Device With a Real Punch

A single full charge of the battery will provide you with up to 20 jump starts of your car, which is quite impressive for such a small device. Despite being small, the unit has a rather powerful amperage output of 1000 Amps. The output power of 1000A will be more than enough to boost the batteries of petrol cars up to 6.0 litres and diesel cars of up to 3.0 litres needed for jump starting.

The design of the jump starter features just a few buttons that will let you easily turn the power and the flashlight on, as well as check the battery charge level. The battery level indicator is quite simple, including 4 low-power LED dots that represent 25% of the overall charge each. Simply put, when all of the lights are lit, the battery is fully charged, while the single blinking dot will tell you that the time of recharging has come.

Finally, the small yet highly efficient carjacker from NOCO is a go-to pick for all kinds of people who own a small vehicle or a motorcycle.

Sealey RS1312HV

Jump-Starts Vehicles Without Breaking a Sweat

When it comes to reliability, only a handful of jump starter devices can show off a good battery that can hold the charge for several weeks, without the need of recharging every now and then. Fortunately, with Sealey RoadStart you can finally have some peace of mind.

While the peak amperage output of this model is not something truly outstanding (only 900 A), it does the job of recharging car batteries quite well. To be exact, the output amperage is just powerful enough to start a vehicle with a displacement of 3 litres and 2 litres (petrol and diesel cars, respectively). The thing that makes it good, though, is the ability to jump-start automobiles with flat batteries even in sub-freezing temperatures.

The heavy-duty battery clamps that come together with the portable battery itself are built to last and are equipped with 72.5-cm long cables that make it easier to start your vehicle according to the circumstances.

Instead of a single jumper cable port, this charger model features two 12V sockets that can be used simultaneously. Thanks to this, you can charge two car batteries at the same time, which is a great feature especially, if such an emergency situation arises.

Review of Sealey RS1312HV RoadStart Emergency Power Pack 12V 900

A Perfect Car Battery Care Kit

Moving on, the device is equipped with a reverse polarity protection circuit that protects both the user and the power pack from overcurrent if you connect the clamps to the car battery in the wrong order. To add more, the independent on/off switch negates the risks of sparks occurring during the jump-starting process.

Furthermore, the Sealey power pack utilises a Lead-Acid battery instead of the regular Lithium-Ion one that other popular charger models have. Due to this, the pack can hold its charge for months on end without losing it, making it one of the most long-lasting batteries available on the market. To give you an idea about the current battery charge levels, the unit features a convenient set of LED indicators on its front panel. Owing to them you will always know when it is time to recharge the power pack. Moreover, a set of additional LED lights can be turned on to act as an SOS signal on the road or for better visibility when you need it the most.

Finally, if you need a reliable, heavy-duty battery pack for your automobile, the RoadStart from Sealey will fit that role without breaking a sweat. The sturdy, rubberised housing coupled with reliable switches that won’t break that easily also make this jump starter durable enough to be used in pretty much any conditions, which should satisfy even the most demanding drivers.

A Great Middle-Ground Solution

Roughness at the edges out of the way, let’s take a quick glance over the features that actually make this jump starter a good device in the first place.

Firstly, it’s electronics. Contrary to many other products both portable and not, this model features a wide array of visual cues on its LCD screen that will conveniently show you the current charging status, voltage, as well as the tips on how to charge different batteries depending on the temperature outside.

Secondly, it’s automatic functions. With this simple device, you don’t need to pick between a dozen different charging options. Simply plug the charger into a power socket, connect the clamps to the battery, press the power button, and the appliance will be ready to go.

Moving on, the output amperage of the device is a bit underwhelming as for a stationary product. With the maximum output of 6 A, this appliance cannot be called the fastest-charging model by any means, however, this is not the main thing that makes it exceptional. The feature that does, though, is the car-care systems that firmly protect the battery from the harmful effects of over-current, reverse-polarity, and potential short-circuits. On top of that, by using this stationary charger, you ensure that your car’s battery will have a significantly longer service life, owing to the charging algorithms that protect the power cells from damage that may occur in case of high-voltage.

To sum things up, this model from BUDDYGO is an excellent appliance designed for battery charging and repair. Its simplicity of use combined with a set of security systems provide a completely care-free experience when it comes to jump-starting or charging a car battery, and we can definitely see why this model is so popular.

What Is a Jump Starter?

If you drive a car, having a jump starter is a must. Anything can happen on the road. Even marker lights left on overnight may drain the battery of your car and lead to its dead engine. Therefore, one of the safety considerations is to always carry with you a jump starter, a multi-functional battery booster that can start a disabled car in a matter of minutes and eliminate the need to ask for someone's help while being on the road. Jump starters are all pretty small in size and don't take up much space in a trunk.

Yet, they can help prevent a lot of problems by giving you a helping hand when you need it most, and quite literally. Take it out, connect to your car, and off you go! In this review, you'll find only the top models of jump starters we've handpicked from all available, and we hope you'll find the best one for your needs.

Aside from a jump starter, you may want to acquire a tyre pressure gauge that will allow you to check the condition of your tires and help your car run smoothly on any road or even off-road. Additionally, we recommend taking a quick look at our car battery charger reviews that are designed to keep the battery of your vehicle in a good shape, no matter the season.

What Features to Compare

Amperage

Now let’s take a close look at what jump starter is and what it's important to look for. We'd like to draw your attention to amperage, required for starting a car engine. The voltage of a battery booster should not outreach the battery voltage.

To make it simple, look for a jump starter with the charging current 10% more of battery capacity. For example, if the current charge of your car battery is 400A, it is recommended to opt for a jump starter with 440A at least.

Some jump starters are quite multifunctional and can be used for charging cell phones, tablets and notebooks. Consider whether a chosen jump starter has got a built-in battery. Travellers are going to highly appreciate it as an additional source of power for use of various camping appliances, like a fan or a large flashlight. The higher this figure is, the more often you’ll be able to boost your battery. The 12V Output that some models come equipped with allows users to connect their favourite gadgets as well as charge PCs, cell phones, tablets and laptops.

Safety Options

All car batteries have negative and positive polarity connections. When you attach jump starters, it’s important to connect them correctly to prevent battery malfunctions. The manufacturers of jump starters have taken care of safety options too. Whenever there's something been connected the wrong way, the protection system will inform you or simply turn itself off. You'd never overheat the charging accumulator, the system ensures that you see its capacity and stop whenever it's needed.

Size

As a rule, compact jump starters come packed with a cover or a special case for convenient transportation and weather protection (consider the size). Due to the additional adapters, you are able to charge your notebook, tablet or smartphone “on the go”. Some of the manufacturers have already included the flashlight which is going to be very helpful at night.

Compressors

The models with built-in compressors are going to be perfect for pumping the wheels as well as filling a ball or a mattress with the air. It can be called an all-in-one solution which takes little space in your car. If you don’t use a car every day, a jump starter without the compressor will be fine. It is convenient to bring around and use as a power source for your mobile devices as well as for other USB-powered devices you may have.

Specifications

Although a jump starter is a great device that will aid you in starting the engine of the vehicle if a battery is completely discharged, it is important to pick the one that suits your car’s model and the swept volume of its engine. This aspect is determined by the output voltage and amperage of the carjacking unit. To put simply - the larger the numbers the bigger the vehicle you can jump-start without having issues. Upon purchasing the model of your choice we recommend taking a closer look at the specifications of the outputs which a particular device has to avoid possible incompatibilities with your vehicle’s battery.

How to Jump-Start Your Car Properly and Safely

Nowadays, virtually every petrol or diesel car needs a battery in order to start the engine. And if you happen to be an owner of a car, motorcycle, ATV, or something in-between, you know how frustrating trying to start a vehicle when its battery is flat can be. The only way around this issue is to jump-start a car. That said, you’d be surprised how many drivers out there don’t know how to do it properly. There is a certain risk involved in utilising the high-powered car batteries as well as other devices that have a low voltage yet high amperage.

Even the amateur electricians and car mechanics will tell you this one thing - it is not the volts but ampers that can kill people. Thus, it is important to use such tools with caution and, at the very least, some basic knowledge of how batteries and car engines work.

Breaking Down The Process

So, what is the right way to jack your battery properly without damaging the heart of your car or, most importantly, without harming yourself? Well, the actual operation is way simpler than it may seem from the first glance. If you are done looking at dead batteries we would like to introduce you all the steps you should follow in order to start the vehicle.

  • First of all, you can jump vehicles with flat batteries by using another car with a charged one or with the help of other external sources such as portable jump starter devices, for example.
  • Moving on, you will need a pair of decent jumper cables since there is a certain risk involved in using poor-quality cables.
  • Make sure that both vehicles’ engines are turned off to prevent electric shock.
  • You will need to connect the positive cable to the positive clamp of the car battery (more often than not, it is the red one). Likewise, connect the other end of the red cable to the positive terminal of the charged battery. When you are done with the red alligator clips, it is time to connect the black cable (negative) to the good battery and the other end of it to the metal part of the hood. That part is not painted in order to prevent sudden electrical discharges.
  • All you'll have to do after you're finished with the jumper cables is start the car with a healthy battery and leave it running for about 3 to 5 minutes before starting the other one, removing jumper cables in the reverse order and, finally, starting the car with a flat battery.
  • Leave the engine of a car that was being charged running for at least 30-40 minutes in order for its battery to be able to recharge naturally. Otherwise, you will have to jump-start your car again next time you would want to start it normally.

Essential Tools

Alternatively, by using the jump starter devices, you won’t need a second car to recharge the battery of your own car. Moreover, the special cables that come together with such tools provide an additional level of safety when it comes to working with electricity. One way or the other, you will definitely need jumper cables at least a couple of times throughout the service life of your car, motorcycle, or truck. Which is exactly why it is important to always keep at least one pair of such tools inside your trunk alongside with the toolbox, air compressor, and other essential instruments and devices.

FAQ:

Q: What main parameters should I look at when choosing a jump starter?

A: The major spec you need to pay attention to when choosing a proper jump starter for your vehicle is the peak amperage it delivers. The higher it is, the bigger engine it will be able to start. For example, a jump starter with the peak amperage of 500 A can easily start a 3L gas engine. Of course, if you drive a large pick-up truck, you should opt for a more powerful jump starter.

Q: There are 12V and 24V jump starters. Which one do I choose?

A: Voltage is also to be taken into account when choosing a jump starter. As usual, cars have 12V batteries and, thus, require a 12V jump starter. 24V batteries are usually used on trucks and, thus, they need 24V ones.

Q: What if I connect the cables to the battery in the wrong order?

A: The majority of modern jump starters have a short circuit protection, so you won’t damage either a jump starter or a battery in case you connect the cables backwards. Most jump starters have a reverse polarity light that warns you that the cables are connected in the wrong order.

Q: What battery types do jump starters have?

A: Most jump starters have Lithium-ion batteries, similar to those used on power banks or cell phones, for example. However, some models are equipped with lead acid batteries.

Q: Do I need to disconnect the battery to jump start my car?

A: No. A jump starter is connected right to the battery of your car. Actually, your car won’t start due to a dead battery and, therefore, a jump starter is required to bring the battery back to life.

Q: How to connect a jump starter to the battery of my car?

A: It is very simple: you need to connect the RED cable to the positive (+) terminal and the BLACK cable to the negative (-) terminal. Afterwards, you can start your car.

Q: How long can a jump starter hold the charge?

A: First of all, it depends on the capacity each device has. Next, the temperature also matters. Batteries tend to lose charge quicker in sub-zero temperatures. Finally, the more often you use the jump starter, the more often you will need to recharge it.

Q: Is it possible to use a jump starter for charging portable devices?

A: If you use a jump starter with a USB port, then yes, it is possible.

Q: How to charge a jump starter?

A: Primarily, a jump starter has an AC plug for charging its battery. However, some models also provide a 12V DC plug that allows you to charge the tool from a 12V car outlet. The latter option is very convenient for people who drive a lot.

Q: Are there jump starters with a built-in air compressor?

A: Yes. Many models in the market come with a built-in air compressor that you can use to inflate tires. The compressor will come in handy if you need to inflate a boat or another inflatable item as well.

Q: Can jump starters be used to start other vehicles but cars?

A: Yes, of course. You can use them to start motorcycles, tractors, jet skis, boats, etc. A jump starter is a really multifunctional tool.
