10 Best Car Battery Chargers

No driver wants a dead battery. Even though phones make getting a tow or a jump easier than it used to be, waiting for assistance can be frustrating, ecspecially when you need to get to your destination. When you have a dead battery, it doesn’t always mean you have to replace what you have. Just like any other battery, car batteries can be recharged in a small amount of time, especially when you’re using the right equipment. Owning a portable battery charger can help keep your car fully functional and avoid the hassles that come with a dead battery. It can do the same thing a quick jumpstart with jumper cables can do, but with longer-lasting results. When it comes to the production of electric power, Nikola Tesla is one of the scientists who made several huge contributions.

Battery chargers come in different power levels and sizes, but some are so large that it’s best used in auto garages than in homes. When it’s too small, it’s not powerful enough to charge larger vehicles. The Schumacher SC1281 Battery Charger offers the best of both worlds – it has high power and is easy to maneuver. With this charger, you get the option to charge your car battery slowly with 2 to 12-amps of power, but it can also provide 30 amps for a quick boost. It can even offer 100 amps to act like a jump starter. This is great to use for true charging, especially for larger vehicles.

This charging unit is a bit large, but it only weighs about 12 pounds and comes with a handle to make carrying easier. Its beefy body is well-constructed. Its charging capability does a great job in getting most batteries up to a usable level in a short amount of time, compared to other battery options.

It’s also a smart battery charger, so you don’t need to worry about overcharging. The trickle charge feature allows you to easily keep an unused battery loaded up, plus the reverse polarity protection ensures that it cannot function when the clamps are attached to the wrong battery terminal, preventing damages and helping it function more safely.

Plus, it comes from a trusted brand, so you can be sure that even though it comes at a low price, it can charge your batteries efficiently. Black & Decker has a whole collection of household gadgets, but it’s not common to find a battery charger in their product lineup. This particular battery makes the brand live up to their reputation.

This battery charger is applicable to a wide range of vehicle types, including motorcycles, lawnmowers, cars, specialty vehicles, ATVs and anything that runs on a 6-volt or 12-volt battery system. It has a capacity of 1.5 amps, which isn’t a lot but it might be enough if you only need to maintain the charge of your battery or if you’re fine with a long charging time.

What’s more, it doesn’t keep on charging a battery even after it’s full to prevent overcharging, thanks to its integrated circuit. This also offers protection against reverse polarity and short-circuiting. It also comes with a built-in mounting bracket for convenient placement. This charger is easy to connect using battery clips and O-ring terminals.

It’s an all-weather battery charger, trickle charger, battery maintainer, and battery desulfator.

Being an automatic charger, there’s little to no manual operation needed on your part. The special programming controlled by its microprocessor allows the charging to be constantly monitored, and charging will stop as soon as the battery is fully-charged. Also, this charger comes with other safety features besides protection against overcharging, such as prevention of reverse polarity and short circuiting. It doesn’t produce sparks and helps protect the battery against excessive charge or discharge.

This option gets the job done well when it comes to making a battery working again. It also helps keep the battery healthy and functioning as a battery maintainer. Its simple design and included directions make it easy to use. This kit comes with SAE adapters that offers quick-release connection options.

But compared with other automatic car battery chargers, this one can start up your dead battery. Customer reviews loved that this charger has the ability to resurrect their batteries that they previously thought dead, saving them money.

This unit is also easy to use. The LCD screen keeps the user updated on the charging progress, and it also offers an easy-to-select range of battery types from which to choose.

  • Charges fast


  • Poor customer service

Like the Plus model, this one is a fully automatic battery charger that comes with a float feature, allowing it to be left unattached to a battery. It charges only when necessary. The Junior Charger is a smaller and more affordable model. It only offers 0.75 amps of power, so don’t expect a quick charge, but if you’re leaving it plugged in, it will be fine. It can automatically charge cars, motorcycles and boats until they’re fully charged.

This is a simple unit with no extra unnecessary features and no extra technology. You can easily plug in your 12V lead acid battery and know that it will maintain and charge well. It’s a trusted brand for reliability and performance by different vehicle manufacturers. It’s also spark-proof, and reverse polarity protected.

This charger is great for workshops and car dealer use, but nothing’s gonna stop you from using it at home in your garage if you want to (and if you can afford to).

This charger works on a wide-range of different types of batteries, including 6- and 12-volt batteries. It’s microprocessor-controlled, so it automatically adjusts the amperage rate to maintain and charge your battery. It also comes with a multi-stage charging for added precision, and an auto voltage detection built-in. The device comes with LED indicators and push button controls.

Since this is a large battery charger, it’s powerful enough to use with trucks, SUVs, and large engines. It comes with a 50A boost mode that allows it to bring deeply discharged batteries back to life. It quickly hooks up to your battery, thanks to its battery clips.

It packs a serious punch along with the ability to charge up more than just a car in distress. A typical jump starter kit is a hard thing to work with, but this model is different.

However, just because it’s small doesn’t mean it compromises on power. It can jump start your car up to 20 times with 800 amps of peak current. With 18,000 mAh capacity and a smart USB port, it can fully charge your laptops, mobile phones, tablets, and more. It’s cleverly designed to avoid major threats to performances such as short-circuiting and overcharging.

However, it cannot jump start a car with anything less than a 30% charge. But you will get a 3-year warranty should the worst happen.


  • Compact design
  • High power output
  • Can be used to charge not only car batteries but also personal electronic devices
  • Comes with safety functions like spark protection, overcharge prevention and reverse polarity protection
