This device is awesome to have around because it is not just a car battery charger. It also is a backup battery for any device under 300 watts. This can be your smartphone, laptop, etc. It also is an air compressor up to 150 PSI. If your tires are ever low, you will enjoy the convenience of filling up from the comfort of your garage. You won’t find that feature anywhere else on this list.

2. Clore Automotive JNC770R Jump-N-Carry

Great at what it does

The Clore Automotive JNC770R is a great jump-starter car battery charger. This device allows you to charge it and keep it with you for emergencies. If you have the money, we think this premium option is a good one.

This product has an AMAZING return policy. They say you can run over it, disassemble it, shoot it with a gun, and still be able to return it. Please don’t do these things because it has an internal battery, but that’s still an awesome warranty.

This portable device also gives you great emergency features that you will not find with a lot of other items on this list. You can charge your phone with the USB ports on the front of the device. This is a device I personally have in my car for peace of mind, and it works great.

This device also has a cigarette lighter port to help you charge your devices with car chargers. I didn’t notice this until I wrote the review, but it also has a flashlight on the front of the device to help provide light when the power is out. You get what you pay for with this device, it’s expensive, but it also has some incredible features.

Out of 5 stars, we decided that the Clore Automotive JNC770R Jump-N-Carry Red 1700 Peak Amp Premium 12 Volt Jump Starter deserved 4.9 out of 5. It does exactly what it’s supposed to do, and is great for emergencies. We would recommend this battery charger for people driving cars with a slight parasitic drain on their batteries, and for those looking for peace of mind where jumper cables might not be possible.

The STANLEY BC25BS Smart 12V Battery Charger is a great automatic battery charger. One of the best features that many people like is that it automatically selects a charge rate for you to extend and maximize your battery life. Another great feature is that their patented engine helps jump-start any car under 2 minutes.

The main reason we are including this device on this list is because of its battery-centric features. This device can check the battery condition to tell you if it’s time to replace it. Not only can it check the status of the battery, but it can also give you the status of the alternator. A bad alternator will leave you stranded more than once, so it’s a good thing to know the status of the alternator.

To our surprise, the STANLEY BC25BS Smart 12V Battery Charger was able to bring our older car batteries back to life! Overall, we were very impressed because the STANLEY BC25BS kept its promise and did start our car in under 2 minutes.

Some people on Amazon have said that their devices were inconsistent with their batteries and did some damage. We didn’t personally experience this, but we still want to keep that in mind.

We still want to give this 4.2 stars out of 5 because when it works, it works really well. If the accident was a fluke, we wouldn’t want to discourage anyone from giving this car battery charger a try. Read the reviews for yourself before purchasing.

Pros

  • Very affordable
  • Helps jump-start cars in under 2 minutes
  • LCD screen
  • Helps extend battery life
  • Alternator Status Reading
  • Safe

Cons

  • Does not charge completely dead batteries
  • It does not support high-amperage requirement

4. Battery Tender Junior Charger and Maintainer

Great Product for a Great Price

The Battery Tender 021-0123 is a great battery charger for all lead, acid, flooded, or sealed car batteries. It is very compact, portable, and cheap. It’s designed to be spark proof with reverse polarity protection and can resume charging if it detects that the battery voltage is low.

In our experience, this is one of the best maintaining chargers on the market. Whether you own a lead-acid battery or drive a motorcycle, this compact battery charger is your best friend.

We highly recommend the Battery Tender 021-0123. We believe that it deserves 4.0 stars out of 5 because the manufacturer was very helpful in getting a replacement charger when we had problems with the first one. Great customer support from manufacturers is usually the difference between a good and bad experience but luckily for us, we had nothing but positive experiences.

Pros

The BEATIT QDSP 2200Amp Peak 12V car Jump Starter was highly recommended from all the emergency car battery charger reviews we read. If you’re interested in finding the best car battery charger and jump starter, the Beatit 800A Peak 18000mAh is a great choice. With 800 amps of peak current power and heavy-duty clamps, it’s able to start your car up to 20 times and more.

This product does have an internal battery, which is important as a backup device. You can simply charge this device, stick it in your glove compartment, and then use it when you need it.

Believe it or not, but the Beatit 800A Peak 18000mAh can be easily fit into your glove compartment. We love it! We usually store a ton of things in our trunk so being able to fit this nifty lifesaver in our glove compartment was a game-changer.

We will admit that we were star struck when we found out how portable this was and how easily it fit into our glove compartment.

It was really nice being able to fit a car battery charger in our glove compartment. We had a really good experience and would still recommend anyone that’s looking for an emergency car battery charger. Buy this product instead of jumper cables if you only choose one.

Our overall experience convinced us to give the BEATIT QDSP 2200Amp Peak 12V car Jump Starter 4 stars out of 5. We would have given it a stronger rating but having it sometimes inconsistent caused us to rate it lower.

Pros

  • Great jump starter
  • Speedy battery charging

The ALLPOWERS 12V 5W Portable Solar Car Boat Power Solar Panel Battery Charger Maintainer is a solar car battery charger that we have used with great success. It’s incredibly affordable, lightweight, and compact to keep in your car. It is able to charge 12V batteries through solar power and also generate 5 watts of energy.

We were experimenting with different car battery chargers when we stumbled upon the ALLPOWERS 18V 5W Battery Charger. We knew that this charger relies on solar power so it really caught our interest. Our main concern was trying to keep our car battery alive until we had time to buy a whole new one.

This is a perfect device to use when going out of town for a while, just stick it in your windshield and plug it into your cigarette lighter, and the car battery will stay charged while out on vacation.

We just want to throw this out there that the ALLPOWERS 18V 5W Battery Charger is very easy to use. All you have to do is simply plug the solar charger into your lighter socket and making sure that there is plenty of sunlight to work with. After that, the ALLPOWERS 18V 5W Battery Charger will do the rest of the work for you.

This battery charger will not be faster than a charger connected to a power socket because it is a solar device, however, it will work anywhere with sun. You should consider this as a travel companion or a daily trickle charger for your battery health if your alternator is not working in optimal condition.

We recommend the ALLPOWERS 18V 5W Battery Charger to anyone that is looking for a short term solution to their car battery problems. We rate this charger 4.5 stars out of 5. It’s a decent product that is worth the money. Just don’t expect perfection.

  • Great warranty
  • Extremely affordable

The NOCO Genius G3500 is truly considered to be the best battery charger for cars. This model comes in a 3.5 amp form that comes with advanced technology that delivers incredible performance. It is designed to charge twice as fast as other chargers. Its compact design makes it really easy to transport and store when not in use.

We discovered this charger after reading many automobile battery charger reviews. It was highly regarded, and therefore we had high expectations for it. Many users have used this as their main home car battery charger and we can see why. The NOCO Genius G3500 is everything you’d want from a car battery charger.

Many of the cars we owned often experienced dead batteries. We used this device on our e46 BMW wagon, and it worked perfectly. That damn car would lose charge after 2 weeks of sitting. The NOCO Genius G3500 is a true miracle worker because it was able to resurrect that battery, which I assumed would be toast. We also had a dead optima redtop battery and after 10 hours, it was able to bring it back to life.

One issue that we did experience was with the charging indicator LED lights. Once in awhile we noticed that the charger did not properly sense the battery voltage properly and only showed an amber light even when connected to a fully charged battery. Although it didn’t pose an issue, this was something that people should be mindful of.

Overall, we had a very good experience with the NOCO Genius G3500. We seriously consider this the best auto battery charger from the many we’ve used.

This battery charger does need to be plugged into an electrical socket, so it is not a backup when out in public, but it can maintain batteries and charge stationary batteries where an electrical socket is available.

From our positive experience, we give the NOCO Genius G3500 4.5 stars out of 5. This is highly recommended for both the quality and the price. If your battery fits these specs, then it’s a must have.

Pros

  • Keeps battery full charged
  • Prevents overcharging
  • Stabilizes battery chemistry
  • Lowers energy consumption on battery
  • Comes with different charging options

Cons

  • Charging LED indicators don’t work properly
  • No cables/accessories included
  • Can’t be used without an electrical socket
  • No internal battery

8. Schumacher SE-5212A

Great Product from a Great Brand

For people that are looking for a handheld battery charger, the Schumacher SE-5212A is a great choice. It’s a fully automatic 12 volt battery charger that has safeguards installed to prevent batteries from overheating. It usually takes about 3 – 5 hours to fully charge a car battery, depending on the battery type.

When we found the Schumacher SE-5212A 2/10/50 from reading portable car battery charger reviews, our goal was to find the best portable car battery charger because we wanted something that was compact and transportable. The Schumacher SE-5212A 2/10/50 only weighs about 10 pounds and is fairly small so you can fit this in any car trunk. We were able to successfully store this in the back of our trunk and for those few times where we did need the car battery charger, this really came in handy.

One disappointment that we experienced was that this car battery charger cannot be shipped to Oregon or California. We had lots of great things to say about this charger and we recommended it to a relative of ours. However, much to our surprise, they weren’t able to have it delivered to their residence in California and ended up picking something else.

Even though they can’t ship it to Oregon or California, we still had a great experience with the Schumacher SE-5212A 2/10/50.

Even with the disappointing setback, we still highly favor the Schumacher SE-5212A 2/10/50 and give it 4.3 stars out of 5. It’s compact, lightweight, and fits nicely in the back of our trunk. It quickly charged our car batteries and it didn’t take up much time either.

Pros

  • Prevents battery overcharging
  • Quick charging
  • Handheld design
  • Easy to follow instructions

Cons

  • Cannot be shipped to Oregon or California
  • Not compatible with WM-12 or EC-25 quick connect cables
  • No internal battery

If you are looking for a car battery charger like the Stanley mentioned above that offers trickle charging, we highly recommend the BLACK+DECKER BC15BD. The BLACK+DECKER BC15BD is one of the most advanced car battery chargers in the market with an LCD screen that tells you the charging and battery status with easy to read icons. It comes with a 3 stage charging feature that automatically switches from fast charge, to top off, to trickle charger.

This charger does have some issues with battery readings. It can read a false positive on a dead battery, and therefore refuse to charge because of it. We still like the Stanley mentioned above over this product.

Pros

  • Built-In Air Compressor
  • Can charge any device that plugs into a standard US outlet
  • Amazing for high voltage batteries
  • Very compact
  • Comes with different charging options

Cons

  • Very noisy when charging.
  • Terrible for trickle charging

The Schumacher SC1319 is a car battery trickle charger. It is one of the bestselling chargers of all time and is perfect for charging batteries that are stowed away in storage. It’s both a 6 and 12 volt battery charger that prevents overcharging with a generous 1 year warranty.

This charger is designed to be smart about charging your car. You have different options for charging and while it is doing its work, you can check the charging amperage, voltage, and percent charged. It also comes preinstalled with an internal fan to keep the temperatures low.

If there was one area that needs improvement, it would definitely be a set of instructions. The Schumacher did not come with a set of instructions so it took some experimenting to learn how to fully use the battery charger. After we were familiar with how the charger functioned, everything was great. It’s not rocket science, so if we figured it out, you can to.

The Schumacher SEM-1562A-CA is definitely a battery charger you can count on for a quick charge. It works especially well with batteries laying around in storage. We had a really good experience with the Schumacher.

Pros

  • Prevents overcharging
  • Great warranty
  • Great for charging batteries in storage
  • Perfect for charging small batteries
  • Great trickle charger

Cons

  • No instructions provided
  • No internal battery

Jumper Cables vs Portable Car Battery Chargers

There are essentially two ways to get going again when you have a dead car battery. You can use jumper cables by connecting your car battery to another car battery and jump start the vehicle. The other option is to use a car battery charger to charge the battery up from an electricity source.

Jumper Cables

Jumper Cables are traditionally the quick fix for car battery issues. This still remains to be the fastest and cheapest ways to get your car started with a dead battery. However, did you know you can further damage your battery with jumper cables?

Depending on the battery of the vehicle you connect the jumper cables to and your car battery, you can seriously damage your battery in some circumstances. The battery of another vehicle can overpower your vehicle and cause damage.

Also, you will likely have to ask a stranger to help you with jump-starting your vehicle, and if there’s nobody nearby, you’re out of luck! You can avoid this awkward or frustrating encounter by purchasing a portable car battery chargers.

Portable Car Battery Chargers

Portable Car Battery Chargers typically do take longer to use than jumper cables because they actually charge your battery up with enough juice to start. Jumper cables draw that required current from another battery.

However, portable car battery chargers provide a solution that is safer, easier, and better for your car than using jumper cables. These portable car battery chargers do not require another vehicle to be nearby, and they will give you a greater sense of safety.

Jump starting your car can be potentially dangerous, and it causes potential destruction to your car battery. Every battery charger we have used has allowed us to charge up the battery, and start the car with the battery instead of jump-starting the car. This will take an hour or so, but you prevent the damage that can occur to your car battery.

Car Battery Maintainers

If you work on cars on a regular basis, you’re probably aware of the need for a car battery maintainer. Sometimes, when you’re working on cars, you want to use the battery, but not let it drain. The battery won’t recharge from the alternator unless the car is running.

You should also use a car battery maintainer and charger when you go on vacation for long durations. Car batteries are not as stable as the battery in your phone, so you can not let it sit without charge. You can potentially ruin your car battery by letting it die just one time. When you go on vacation, you should hook up a car battery charger on maintainer mode to keep your battery healthy while you are away.

A lot of the car battery chargers mentioned on this list have the ability to trickle charge batteries, which makes them a car battery maintainer. It’s a good feature to look for when looking for a car battery charger.

Best Car Battery Charger Brands

There is a large variation of car charger brands on the market, and it appears that some are way better than others. Here are some popular brands for car battery chargers on the market.

  • NOCO
  • Schumacher
  • POTEK
  • Battery Tender
  • Stanley

Types of Car Batteries

You should consider battery chemistries and voltages when deciding on a portable car battery charger.

Battery Chemistries

There are different types of car batteries that will have different levels of success with car battery chargers. Your car most likely has a battery of one of these types:

  • Maintenance Free
  • Wet Cell (Flooded)
  • Absorbed Glass Mat (AGM)
  • Gel Cell
  • Value-Regulated Lead Acid (VRLA)

The best portable car battery chargers will include the ability to charge all the popular types of car batteries effectively, so you should not need to worry. Most devices will state if they do not work with a specific type of car battery.

Voltages

Depending on your vehicle, your battery will have different voltage ratings. The common voltages for car batteries include:

  • 8 Volts
  • 10 Volts
  • 12 Volts

You should consider which of these options your vehicle accepts, and consider that when purchasing a portable car battery charger

Overview

You need to be sure to match both the voltage capability and battery chemistry capability on your car battery charger. You can find this information with technical specifications.

Battery Amp Hours

Figuring out how many amp hours your battery stores is very important. A standard full sized battery usually houses about 50 amp hours, so a 10 amp charger would be used to charge it.It helps to know this information because it’ll tell you how long it’ll take for your car battery to fully charge with a given car battery charger. Below is a few examples of how long it’ll take to fully charge a car battery if it were completely dead:

  • 50 Amp Hours: 6 hours on a 10 amp charger
  • 100 Amp Hours: 11 hours on a 10 amp charger

If you want a formula to help you figure out how long your charge time will be, take the amp hour rating of your battery and divide it by the charger rating (amps) and then add approximately 15% as a cushion for the final calculation. Having a more powerful charger may take longer, but will save a lot of time.
