The Best Car Battery Chargers Reviewed
Most of us have had an experience of our car seemingly deciding not to start on us. For many people, this is a huge disruption, grounding you on the spot until you’re able to call someone out to fix it.
For those with a automotive battery charger, however, that’s not the case. Keeping a battery charger in the home or somewhere in the car ensures that you can always get on the road.
With that in mind, we’re going to look at how to choose the best car battery charger and why it matters.
If you want to reduce your chances of a dead battery stopping you in your tracks, then this is an essential piece of equipment for just about any driver. What’s more, there are more advanced battery chargers out there that can give you more than a dose of juice when you need it.
Modern car battery chargers can even condition and maintain your battery so that its overall longevity is improved. When you simply want to make sure you always have some charge in the batteries or you want to improve their overall cost-effectiveness, choosing the right charger is important.
Car Battery Charger Features To Consider
But what, exactly, makes the right car battery charger? Here, we’re going to look at some of the features that can ensure more convenience, the best performance, charge efficiency, and even improved car battery maintenance.
- Voltage: This is the measure of electric power provided by the charger. Matching your car’s battery to the charger voltage is important and, in most cases, that lies at 12V. Other chargers can work with it. Multifunctional chargers that provide 6V of power also work with other batteries such as jet ski batteries but are slightly less efficient.
- Amperage: This is how much current the charger can supply at any one given time, and often dictates how quickly your charge helps your battery get its full charge back, though fast charging can also impact the battery’s longevity. Most chargers come with multiple amperage settings and auto settings to find the ideal rate without your intervention.
- Safety features: To avoid giving yourself a shock or overcharging the battery, safety features like auto voltage/amperage detection, reverse polarity features and spark-resistant clamps are important.
- Extras: A good car battery charger kit can come with extras like effectively long jump cables, battery diagnostic tools, trick charging, a maintenance mode and jumpstart features.
With that out of the way, it’s time to look at some of the best car battery chargers on the market.

Best Car Battery Charger
The bottom line is that not all chargers are created equal. Some are clearly better than others, both in features and also in price. Taking those factors in mind, along with feedback from people who own them, here are our picks for the best car battery chargers:
Although one of the most expensive chargers featured here, it has some specific advantages worth noting. NOCO is a well-trusted brand and that’s not just due to their longevity and resilience. With a small, compact design, it’s easy to transport, use, and store in the boot or the garage.
Heavy duty battery clamps are an example of solid, reliable design while the quick-connect and disconnect plugs make the task of charging the battery much more efficient.
The battery maintenance functions of the NOCO Genius G15000 charger are well worth lauding as well. Though charging dry batteries can take very long on the slow setting, up to 14 hours, it can help restore the battery to near-peak efficiency.
The smart charge function will automatically adjust the charge rate, so leaving it on for too long and the risk of overcharging isn’t a concern and, either. Good spark proof technology and reverse battery protection make it an overall effective, efficient, and safe tool to use that’s relatively simple for even the most automotive illiterate drivers.
- A powerful, professional grade battery charger and battery maintenance tool designed to recharge all types of batteries rapidly in workshops, garages or those you simply want the best.
- Perfect for keeping your vehicles fully-charged and maintained during year-round battery maintenance or long-term storage for improved performance and longevity.
- Works with all types of 12-volt and 24-volt lead-acid batteries, including Wet, Gel, and AGM, or any common automotive, deep-cycle, marine, or maintenance-free battery.
- Keep your battery fully charged without worry or overcharge. Simply plug-in and let our advanced charging technology automatically monitor and maintain your battery. Progressive repair mode for heavily sulfated 12V batteries.
- Use our advanced Repair Mode to reverse the damaging effects when batteries are left uncharged for extended periods to improve battery performance and longevity.
Selling for slightly higher than the NOCO Genius G15000, depending on where you find it, this is one of the most powerful car chargers on the market, able to deliver 1,700 peaks of jump-starting power.
Beyond charging the battery, this means that it can bring engines back to life in even the coldest of conditions. It has similar charge restoring power to the NOCO Genius but is even more time-efficient when it comes to bringing a totally dead battery back to full charge.
It’s also an efficient tool to use, as well. Especially light-weight and compact, it’s much easier to transport and store, while the thick 46-inch jumper cables mean that you’re not going to have to stretch too far to get some effective use out of it.
With no power switch function, it’s important that the cables are stored correctly and kept separate to avoid sparks, so it does lose a few points for lacking the right safety functions there. Similarly, there’s no reverse polarity detection, so connection errors are a distinct possibility.
For that reason, always make sure you’re connecting the right jumper cable to the right terminal. That said, the cables and clamps are spark-resistant with thick insulation, so they are reliable and long-lasting, provided you take care of them.
- 1,700 Peak Amps; 425 Cranking Amps
- 22Ah Clore PROFORMER Battery
- 46" Heavy-Duty #2 AWG Cables
- Voltmeter provides charge status of onboard battery
- DC outlet to power 12 volt accessories; DC input to recharge internal battery
As a 12V trickle charger, it’s much more versatile, able to charge a wide range of vehicles even if it might not be quite as efficient at charging your car. What’s more, the excellent NOCO standards for safety are all here, with reverse polarity detection and spark resistance as standard.
As a safety feature, it comes with a strobe light function so that if you’re stuck on the side of the road, you can make sure other drivers are well alerted to your presence.
One extra that’s particularly nice is the USB port, which allows you to charge smartphones, laptops, and other digital devices by simply using it as a charging dock.
It’s a decent price, less expensive on average than the other two reviewed so far, but if you’re willing to pay more, you can get the same charger with even more Amperage, though 1000 might be all that you really need. Sharing much the same design as the Genius G15000, it’s just as easy to carry, store, and use, as well.

With serious power that’s nearly on the level of the Clore Automotive Jump-N-Carry, the POTEK Portable Power source has some significant jump-starting capabilities, but it’s a much more versatile device than it lets on.
This device can power up not only the car and other vehicles thanks to trickle charge technology but is even designed to be used with home appliances up to 115-volt appliances thanks to its AC and USB ports. With an instant amperage of 750, and a peak of 1500, it can help you get your engine started in almost all conditions.
The versatility doesn’t stop there, however, as it comes with an air compressor and air pressure gauge that can be used to deliver compressed air to flat tires, though it is somewhat noisy.
Though it has no reverse polarity detection, meaning you should be careful which ends you connect the cables to, it does have several electrical safety features, including spark prevention, that makes using it relatively foolproof.
Though slightly heavier than other portable chargers mentioned here, it’s rugged, solid design and the sheer versatility of it make it a great emergency multi-use tool that’s especially good for those who enjoy taking their vehicle for outdoor adventures such as camping.

The low price, compared to the other entries, makes a little more sense when looking at its peak amperage of 600, which means it may have trouble starting your engine in bad weather conditions, but it’s still an effective and efficient charger.
Easily stored in the glovebox, it has smart charging capability that can both quickly charge a battery in good health but also bring a truly dead battery back to life over a longer time.
With good electrical protection and an extremely lightweight, convenient design, it justifies its lower price, but the jumper cables aren’t quite as strong as in the other battery chargers.

All of the car battery chargers mentioned here have their specific benefits and drawbacks. If we were to recommend one, the mix of power and versatility that the NOCO Genius Boost Plus GB40, paired with its excellent safety features, make it the easiest to recommend. For those looking for a more versatile, multi-use tool that also includes a battery charger and jump starter, however, the POTEK Portable Charger is also well worth recommending.
