Best Portable Jump Starters of 2024, Tested and Reviewed

Is there any better feeling than seeing your vehicle through the trees after an exhausting hike? I don’t think so, but that elation turns to horror in a hurry when you turn the key and nothing happens. But if you invest in a portable jump starter, this no-service nightmare wouldn’t seem so scary. Soon enough that engine would shake back to life and get you headed safely home. If you’re in the market for a jump starter to keep in your car or truck, I’ve narrowed the vast options to a handful of great ones. Here are my picks for the best portable jump starters.

How I Chose the Best Portable Jump Starters

I started off the quest for the best portable jump starters by consulting friends and acquaintances in the auto industry and narrowed the results to the repeated recommendations of these professionals. I took down notes on their real world experiences with each product. Then I got my hands on as many of the contenders as I could and used them to jump an intentionally drained battery in a 2015 Ford Escape for small engines and an always dying battery in a 6.0 Liter gasoline V8 in a 2006 GMC Yukon XL for larger engines. Then I tested the utility of the accessories by charging several devices, and filled up pickup and horse trailer tires with those equipped with air compressors.

Keeping in mind the different needs of different users and vehicles, these are my selections for the best portable jump starters.

Best Portable Jump Starters: Reviews & Recommendations 

Best Portable Jump Starter: Hulkman Alpha 85 2000A Jump Starter

Key Features

• Peak Amps: 2000
• Battery Size: 20,000 mAH
• Extra Features: Flashlight, one USB-A port, one USB-C port, one 12V DC plug

Pros

• Good power
• Good battery
• Good ports
• Quick charging

Cons

This is the Goldilocks option in a tight race for the best portable jump starter. With a powerful 2000 peak Amps and a 20,000 mAH battery, the Alpha 85 has the juice to turn over huge gasoline engines and most diesel engines to boot. Besides the usual flashlight and USB ports, there is also a DC 12v plug to power other accessories like a separate air compressor. Maybe most impressive of all is the fact that the Alpha 85 only takes an hour and a half to charge fully. The price is “just right” too at around $150. This option will work for most drivers in most conditions, and industry professionals I spoke to frequently pointed to the Alpha 85 as an easy recommendation.

Best Budget: S ZEVZ ET03

Key Features

• Jump up to 8.0 liter gas engines and up to 7.0 liter diesel engines
• 50 jump starts on a single charge
• Can be used as a 74Wh portable power bank
• Two  5V/2A USB output ports
• 400-lumen flashlight
• 24-month standby time
• Protection against overcharging, reverse polarity, short circuits, power surging, and sparking
• Price: $80 (goes on sale for $60 often)

Pros

• Small and easy to store
• Long standby time
• Wide range of operating temperatures (14℉ to 140℉)

Cons

• Not ideal for people who live in cold environments
• Not water resistant

This budget jump starter is a great option for people who live in areas where temps don’t dip into the teens too often. It will hold its charge for a long time and it can survive being in a 140-degree car. But, it might not be able to generate enough juice when temps are in the single digits or lower. It comes with a USB-C charging cable, storage tote, and jumper cables. Mine only took a 30 minutes to go from a 75 percent charge to fully charged, so it should easily hit 100 percent on an overnight charge.

This isn’t the best portable jump starter for people who will use it often or in inclement weather. This is a great option for people who don’t want to spend $200 on a premium option and want something to have in case of an emergency.

Best All Weather: Noco Boost Plus GB40

Key Features

• Peak Amps: 1000
• Battery Size: 2000 mAH
• Extra Features: Flashlight, 1 USB-A Port

Pros 

• Durable build
• IP65 water resistant
• Good power for size

Cons

• Single USB out
• Small battery

This portable jump starter is not only light and compact at 2 pounds, 2 ounces and 8 inches long (without cables), but it is also IP65 water resistant and durably armored. It has a good multi-mode flashlight and a single USB port for charging a phone or other small device. I found the battery cables easy to connect, but they are short at 6 inches. You pretty much need to have the GB40 sitting on the battery to get a connection. At $99 it is a good value. While rated to start larger 6.0 liter gas and smaller 3.0 liter diesel engines, I think it is best for standard gas engines with its somewhat limited 2000 mAH capacity. The GB40 is the perfect solution for somebody with a mid size SUV that also has to get the 17-foot fishing boat started.

Best Value: Type S 12V 6.0L Battery Jump Starter

Key Features

• Peak Amps: 400
• Battery Size: 8000 mAH
• Extra Features: Flashlight, one USB-A Port, one USB-C Port

Pros

Cons

You probably saw this little guy at Costco the last time you picked up toilet paper. At $69.99 it is hard to beat for value. Sure it only has 400 peak Amps available, but you can get repeated start attempts with the 8000 mAH battery. It isn’t as durably built or as powerful as the Noco, but it is a great value, and at 1 pound, 10 ounces and 8.5 inches long in the case, the Type S disappears into a glove box. Unfortunately, there is no manual mode for the Type S portable jump starter. The Type S did get the 6.0 liter gas engine started, except when the battery was completely depleted. I had to go to a more powerful jump starter in those cases. The Type S is a good budget choice for those with small to midsize cars and SUVs or need to get smaller boats and ATVs started. It’s certainly one worth considering in this field of the best portable jump starters.

Best for Diesel Trucks: Gooloo GT4000S Jump Starter

Key Features

• Peak Amps: 4000
• Battery Size: 26,800 mAH
• Extra Features: Flashlight, two USB-A ports, one USB C port, 1 15V DC plug

Pros

• Power to spare
• Big battery

Cons

Diesel engines are big and heavy. They require a lot of power to get all that mass moving, especially in cold weather. Gooloo has oil-burners covered with the powerful GT4000S Jump Starter. At a whopping 4000 peak amps, and ample 26,800 mAH battery, there is enough juice to turn even the biggest diesel engines in a 3/4 ton pickup. Diesel mechanics I spoke to didn’t hesitate to recommend the GT4000s for the diesel driver’s peace of mind. The GT4000S isn’t just powerful, though; it also comes with a decent flashlight and two USB ports. A big, easy to read, 3.3-inch LCD display keeps you up to date on what’s happening as well. At $209 retail, it is more expensive than smaller, less powerful options, but the cost will be easily worth it to the stranded diesel pickup driver.

Best Jump Starter with an Air Compressor: DeWalt DXAEPS14 Power Station

Key Features

• Peak Amps: 1600
• Battery Size: Lead acid battery
• Extra Features: Area light, four USB-A ports, two 120 volt DC outlets (integrated inverter), air compressor, alternator check

Pros

• Lots of features and utility

Cons

• It’s huge
• User has to keep track of proprietary charger

Now here is a portable jump starter with a long list of features. The Power Station doesn’t just have 1600 Peak Amps that are good for even large gas engines, but a light, four USB A ports, two DC outlets from an integrated inverter, an alternator check feature, and … a 120 PSI air compressor. Sure, it is 20 pounds and over a foot tall, but that air compressor can help you limp your Tacoma with a slow leak in the rear tire out of the woods. You set the desired pressure and it quits inflating when it reaches that pressure. I tested this feature several times and it worked perfectly for me. 

For jumping your truck, the Power Station’s 2-foot cords are much longer than the others in this evaluation, which I really appreciated. You have to work around the Power Station’s considerable bulk. Besides the bulk, the Power Station has the downside of a dedicated charger cord that needs to be kept track of (and no compartment for it in the Power Station itself). Speaking of the charging cord, I am concerned about the durability of the flimsy connection where the cord connects to the Power Station. With these caveats, the Power Station still has a lot of bases covered for a retail price around $200. The Power Station is a good choice for full-size pickup owners that have the room to store it and value the extra features.

Things to Consider Before Buying the Best Portable Jump Starter

Jump starters can help you out for more than just reanimating your dead rig. Besides saving you the time and inconvenience of being stranded, jump starters can save you on towing and roadside assistance fees. They are pretty inexpensive insurance and often pay for themselves on the first use. You can also swoop in to rescue another motorist in trouble.

Engine Size 

The size of your car’s engine will determine the size of the portable jump starter you need. Small engines need less power to turn the moving parts of the engine to get it running, while larger engines require greater energy. Most jump starters advertise the largest engines they are rated to start, but buyers should know this is under ideal conditions, and those driving large gas or diesel engines should “size up” to account for cold weather and other jump starting challenges.

Peak Amps

The peak amps is the amount of current that the jump starter can provide. The higher the peak amp rating, the better the jump starter will be able to start a dead battery, and the larger the engine it will start.

Capacity

This is the amount of energy stored in the jump starter’s battery, usually denoted in milliampere/hour (mAH). The higher the mAH rating, the more jumps the jump starter can provide without recharging.

Extra Features

The best portable jump starters have additional features, such as USB ports, flashlights, and even air compressors. These features add real functionality for a wide variety of situations in addition to a dead battery. Sometimes out in the woods, charging a phone or satellite communicator can be as much of a lifesaver as getting your vehicle running.

Safety and Reliability

A jump starter is of no use if it isn’t charged. Most of the jump starters in this review will hold a charge for six months or longer, but it is a good idea to set an alert in your phone to check them and top them off regularly.

It is important to note that you should never touch the positive and negative terminals of the battery with the clamps at the same time. This can create a spark that could ignite the hydrogen gas that is released from the battery. 

Do not smoke or have open flames near the battery.

If the battery is leaking, don’t attempt to jump it.

“Override” or “Manual” Modes

Some jump starters often detect the remaining voltage in the vehicle battery before they can activate their jump functionality. If they detect too low of voltage (usually around 2 volts) they won’t activate. In these cases they often have an override or manual mode that lets the user force current to the battery. This is a great feature especially when cold weather has drained the battery completely.

How to Use a Portable Jump Starter

It is important to follow the instructions provided with your particular jump starter, but they all generally follow the following sequence:

1. Turn off any draws on the battery like AC, radio, accessories, etc.
2. Connect the red positive clamp to the positive terminal of the dead battery.
3. Connect the black negative clamp to the negative terminal of the dead battery.
4. Turn on the car jump starter.
5. Start the car.
6. Once the car is started, disconnect the car jump starter.
