The GP200 is our top pick when it comes to ultra-portable jump-starters considering that it packs a high-powered 1,000 amperes output into a small 6” box. What does that mean? It means that this tiny thing is powerful enough to bring large trucks back to life, but is still small enough to fit under a passenger seat or even in a glove box.
Given its compact size, you can take the GOOLOO GP200 camping or hiking to charge your electronic devices.
Since the GOOLOO GP200 packs a rechargeable lithium-ion battery, it still works even in temperatures that make your battery prone to discharging. This jump-starter can also serve as a mobile device charger and comes with two dedicated USB ports that you can use to charge up your tablets and smartphone while camping or driving.
The device’s battery is capable of jump-starting a vehicle approximately 30 times on a single charge. The GP200 has a charging indicator on its LCD screen that notifies you when it is running low on power.
However, the GOOLOO GP200 has one downside – its cables, which are only 6-inches long. It is worth noting that this is the standard length for most ultra-portable car battery charger cables. But, considering that they are too short, it can be hard to reach the battery’s connections, especially if your battery is quite huge. However, this is a minor inconvenience that’s easily outweighed by the charger’s portability and the fact that it has an LED flashlight that you can use to provide light in dark and low-light conditions.

Your Guide To Buying Car Battery Chargers
While every product that we have reviewed are presumably battery chargers for cars, some are slightly more specialized in their functions, and even though they are able to charge car batteries, their intended use is actually geared towards other tasks. In most cases, this leans more towards the way the battery-charger interacts with a battery when each reaches different levels of charging. It is important to note that not all the battery charger types are designed to charge batteries which are drained completely. Similarly, certain battery chargers have been designed for use on the older batteries which otherwise would have been on their way out.
This happens to be the “middle ground” in association with various battery charger types. These chargers are not able to recharge a battery that is completely drained like the standard chargers are able to. At the same time, they are also not heavily focused on restoring the cells of the battery to its former state. Rather, these battery chargers are designed to keep batteries that still contain some charge from running out completely along with providing a certain level of cell maintenance in the process. These battery chargers are usually not capable of handling battery issues that are more extreme. In addition to these factors, the individual models will often be limited to the battery type that it is able to charge.
These are standard battery charger types and is the type more commonly used unless there is a fairly particular type of circumstance. These chargers come in several varied permutations which include the majority of the battery types, the highest level of voltages and amperages. What this basically means is that, regardless of the type of battery you have in your car, there will be a standard-charger which is able to handle it. One stand out advantage about the standard chargers is the ability to charge batteries which are completely drained. In addition, these chargers are usually inexpensive when compared to their counterparts. They are also designed for a much wider range when it comes to vehicles when compared to other car battery charger types.
This type is less common, while the charging functions in truth are just a necessity of the actual function of this product. In essence, the restorer has the ability to break-down different types of contaminant build-ups in the cells of the battery to restore the functions of the battery in order to hold electric charges. This typically takes place through a number of manipulations associated with the charging-energy which will then realign the constituents in the cells or break-down any byproducts. This car battery-charger type is typically expensive when compared to other types and only becomes necessary when you have many batteries and vehicles that need to be charged and restored regularly. If you only own a single vehicle and you do not require any other uses for these chargers, this is not a purchase regarded as worthwhile.
The voltage types that the car battery-charger is able to produce will determine if it is appropriate for use when it comes to the battery in your vehicle. For example, the car battery charger is often used for charging batteries in other types of vehicles too. Marine crafts and trucks all use the car-battery chargers, with many that use batteries which is not a standard 12V which cars generally use.
Fortunately, there are many car-battery charges available which offer an extensive array of differing battery voltages which they are able to distribute. In fact, there are even the chargers that are able to charge low voltages of 6V and even up to the high voltages of 48V. This ultimately means that a car battery charger is able to service the vehicles which range from as small as a go-kart onto large industrial vehicles.
This forms an important part of the modern chargers used for car batteries. The latest versions feature different types of safety features that protect the batteries and the driver of the vehicle. Below are a few of the primary safety features to expect from the good-quality car battery chargers:
- Spark-proof clamps
- Reverse polarity alarm
- Float Mode
- Battery tester
- Clamp amps
Similar to voltages, the range is far stretching when it comes to the amperages that the different battery types require. With this in mind, similar to the different voltages that car battery chargers are able to provide, so do a lot of the car-battery chargers offer the option to distribute electricity using different amperages. In some cases, the chargers will have the ability to differentiate the amperage required by itself. On the other hand, you will need to find out what type of amperage the batteries will need and then manually set the charger to a specific amperage.
It is important to know that the different types of amperage also has an effect on how fast or slow the charger will be able to charge the batteries. It is still better to take care as many batteries have a maximum amperage-rating, and when this point has been exceeded it may become dangerous to carry on charging the battery. In these cases, you could risk damaging the charger or the battery.
This feature is able to significantly improve the performance of the car-battery charger, yet it is not always necessary. The car battery chargers that have differing charge phases will be able to initially read electrical signals associated with the battery followed by decoding information in order to establish the state that the battery is actually in. These chargers then adjust their own charge setting to accommodate the battery so that it can respond to potential issues.
The more common phase type that extends further than just charging associated with car-battery charges feature several charging phases which includes the Maintenance Phase, which actually doesn’t provide batteries with restorative benefits. Instead, the Maintenance Charging stage will identify what type of amperage the battery needs, the energy amount that this battery releases when it is plugged up yet not powering, where it will continue to provide that amount without overcharging the battery.
This is a standard feature among the majority of the low-ampere chargers, and we would never suggest buying products that do not include this feature. The active monitoring provides the charger with a way to give you more information about the battery.
Lower ampere versions use this feature to establish when a battery that is unused starts to lose charge. This activates the battery in order to allow for a way to start charging, followed by switching off again to avoid overcharging as soon as it detects a full charge in the battery.
The chargers that are more comprehensive feature active monitoring that is more informative. These charger types are able to provide detailed information when it comes to the health status of the battery. They can also indicate when the battery is losing life permanently, indicate the amount of charge present in the battery, and safeguard against the common types of battery depleters which lengthens the overall lifespan of the battery.
The battery charges that are included in this list also include repair modes. The main purpose of these chargers is to offer a way to extend the life of a battery and a way to recharge without having to take the battery to a mechanic. This is the reason why we regard the repair mode as an important feature when it comes to car battery chargers. This is a feature that minimizes build-up which prolongs the battery life.
This is a feature which is not very common between the different models. It usually costs a lot more to buy the battery chargers that are able to start a car, as they take way more power. If you are looking for security in knowing you will never be left stranded when the battery in your car dies, this is a really nice feature.
AGM, which stands for absorbent glass mat, is one of the more common features in the latest car battery charger models. The older vehicles won’t benefit from this feature, but the newer cars may feature AGM batteries. This battery works in a similar way, but the chemicals in the battery are stored inside glass sheets, instead of a liquid interior. This battery is more common in the latest luxury cars and motorcycles.
When you examine your battery, you should be able to find out the type. The more common batteries include Gel (gel-filled), FLM (flooded lead acid), or AGM batteries. You need to ensure that the charger matches up to the type of battery that you have in your car.
In previous years, if you needed to charge the battery in your car, it was likely that the actual charger was about the same size as the actual battery. This used to make it inconvenient to carry around a charger with you. Thanks to technology, the battery chargers for cars today are now so small that some can even fit into a purse or your hand. Yet these compact sizes present even more benefits in addition to convenience.
For example, in some situations, you might want to charge a battery for a car without the involvement of a vehicle. There are a number of circumstances whereby car batteries are used to power electronic arrays that are unrelated. In these situations. It may be a better idea to keep one of the maintenance chargers connected permanently. This is a much easier task with the compact car battery chargers, and it makes moving an array much easier.
Unlike batteries which may need charging, the car battery charger is not a device that features protection from outdoor elements. The majority of these chargers is made up of circuit boards and wires along with a power transformer that changes AC input-electricity into a DC output-electricity for batteries. For this reason, if the charger is not sufficiently protected, it may fail or become damaged from exposure to such elements.
In these situations, your 2 main concerns will be dust and water. Heat may also present an issue, yet this is usually easy to handle by making sure the battery charger stays out of the sun. When it comes to dust and water, the IP rating system will determine the resistance that the car-battery charger has to these types of contaminants. This feature is a lot more important for the chargers that are used for charging the non-vehicle electronics.
Fast Charging Or Maintain Charging
You also need to determine whether you want to use the charger for fast charging or maintain-charge. If you plan to mostly maintenance charge, it is advisable to choose the chargers that charge using a lower amperage that features active-charging monitoring. If you plan to frequently charge a car battery fast, choose the type that gives more amperes, and if necessary a jump-start function.
Wall Socket Connector
You also need to ensure that the car-battery charger that you are interested in purchasing will come with a wall-socket connector that is used in your country. Every country uses its own type of wall socket connector, and the location of the manufacturer may be in another country.
This might be an expensive purchase. If you do not plan to use the charger right away, keep in mind that problems may not arise immediately, when you are buying the product for an emergency backup. Due to this, you need to ensure the charger comes with suitable warranty coverage. The standard includes a 5-year warranty, with some models that cover even longer.
In addition to the warranty, make sure you do a bit of research about the company. Your warranty will not mean much if the company has a bad reputation when it comes to customer service. In addition, some companies will make you pay to ship back a faulty product in order to conduct the repair work. For the heavier items, a lower-end model could cost just about the same to redeem your warranty than buying a brand new product, and these processes usually take a lot longer.
How To Charge A Car Battery With A Battery Charger?
1. Setting Up and Connecting the Charger
While setting up, it is essential to ensure that the charger is off or not connected to the power source. The next step is connecting the positive terminal (red) side of the charger to the positive side of the battery, and negative (black) to the negative.
2. Charger Settings
The next step is setting the voltage (volts) and current (amps). You should consider configuring the charger at its lowest setting and allow the battery to be charged slowly. If you are in a hurry, then you can set the charger is a little bit higher for a quick charge, but you should never do this often. It is not recommended to do so that your car battery could last for long.
3. Plug in The Charger to A Power Source
The next step is to connect the charger into a power source and go about your business. A good car charger comes with a timing feature or with an automatic shut off function when charging is complete. Note: it is not wise to play the cord or move it around when it is still charging.
You should disconnect the battery when it has fully charged. To do this safely, you should first turn off the battery charger and then remove the battery from the charger’s outlets. It is wise to remove the negative clamp first and then followed by the positive clamp. Your battery is fully charged at this point, and you should be ready to go.
Anytime you want to charge your battery; it is advisable to wear protective gear. This means that you should always wear safety goggles and protective gloves. Remember, when charging your battery, there is still a risk of it exploding. For this reason, you should always follow appropriated battery safety and maintenance protocols.
Frequently Asked Questions
Can I Charge a Dead battery?
This depends on your definition of “Dead Battery”.
If you are referring to a completely flat battery due to continuous use (like forgetting to turn off your car headlights overnight), then the answer is YES! With the correct voltage and current setting, the battery can be recharged.
On the other hand, if you are referring to car batteries that are spoiled, then, unfortunately, you cannot charge them. As a matter of fact, charging a spoiled car battery may explode or cause other damaged. The truth is that car batteries do go bad (have a predetermined lifespan). However, through proper maintenance, the battery will have an extended lifespan, but in the long run, it will die. The only solution to a dead car battery is replacing it.
Charger Vs. Jumper: – What Is the Difference?
One is used to Charge A car battery, whereas the other is used to provide the same surge of power needed to start a car.
The truth is that both do help to boost the power of a car battery; however, there is a vast difference between a charger and a jumper. All you have to note is that jumpers are primarily used as an extra battery. They are generally designed to deliver a surge of power needed to get a car started, and then the car recharges the battery.
A car battery charger, on the other hand, is as the name suggests, it charges the car battery and at the same time, can be used to start your car.
Will Leaving a Car Battery Charger On for Too Long Damage It?
Leaving the car charger continuously connected even at its lowest amp may damage it. As such, if it is a must to leave your charger connected for long, then you should consider investing in intelligent car chargers. Such a type of charger will switch itself off when the battery is fully charged, or when you have forgotten to disconnect it from the power source.
Do Solar Car Battery Chargers Work?
Solar powered car batteries work very well. The only limitation is that they are not as powerful as those using electrical power because they put out low amps. As such, they are the best for battery maintenance or slow battery charging. A majority of them do come with additional features such as cigarette lighter socket adapter, gorilla clamps, and others.
The best solar-powered car battery charger should put out between 500mA to 1500mA. The power will be enough to charge a car battery. They are best for those who love the outdoors, like camping, road trips, and more.
How Long with A Car Charger Take TO Charge My Battery?
This Depends On the Method and Battery charger power output.
The truth is that the time taken to charge a car battery will depend on the method used and the charger output power.
