Best Lithium Ion Battery Jump Starter for Cars and Trucks

Best Lithium Ion Battery Jump Starter

A strong lithium ion battery jump starter combines enough peak current for your engine with compatible 12V connections and useful emergency features. The NOCO Boost GB70 suits drivers who want a higher-capacity option for larger engines, while the smaller NOCO Boost GB40 is a practical choice for many cars and light trucks. This roundup compares 10 models, from 1,000A to 6,000A peak output, and distinguishes advertised engine limits, stated starts per charge, charging options and portability.

Those figures help narrow the choice, but peak amps alone do not establish compatibility: check the manufacturer’s engine guidance and your vehicle’s battery type before buying. Consider whether you also need a power bank, fast recharging or a light, and keep the unit charged according to its instructions.

The NOCO Boost GB70 is the best overall pick because it combines 2,000A peak lithium power with stated support for engines up to 8.0L gas and 6.0L diesel, plus up to 40 starts per charge. Its spark-proof and reverse-polarity protection and included heavy-duty clamps make it a well-rounded option for drivers who want more capacity than the GB40. Choose a smaller or higher-output alternative if portability or a different engine limit matters more.

Detailed Reviews: Best Lithium Ion Battery Jump Starter

NOCO Boost GB70

#1 · Best Overall

1. NOCO Boost GB70

  • Voltage: 12 V
  • Battery Capacity: 5000 milliamp hours
  • Compatible with Vehicle Type: ATV, Motorcycle, Passenger Car, RV, Tractor…

Best for: Larger-engine roadside backup.

Why it ranks #1: Its 2,000A output is rated for engines up to 8.0L gas and 6.0L diesel, with up to 40 starts per charge and safety protections.

The NOCO Boost GB70’s 2000 peak amps support engines up to 8.0L gas and 6.0L diesel, giving owners of larger vehicles more starting capacity than a compact 1000-amp unit. It provides up to 40 starts per charge and also serves as an emergency power bank for mobile devices.

Spark-proof and reverse-polarity protection help reduce connection errors on 12V vehicles, useful when a dead battery leaves little room for troubleshooting. Its 40-start rating provides substantial reserve across repeated use, while the integrated power bank can deliver emergency power to smartphones and tablets. Recharging takes six hours, so topping it up requires planning after use. At 2 kg and with a larger form factor than pocket-size boosters, it makes most sense in a truck, RV, or garage kit where engine capacity matters.

Pros
  • 2000 peak amps for engines up to 8.0L gas and 6.0L diesel
  • Up to 40 starts per charge
  • Spark-proof and reverse-polarity protection
  • Integrated power bank for phones and tablets
Cons
  • A full recharge takes six hours.

Skip it if you want a lighter unit for engines up to 6.0L gas and 3.0L diesel; the NOCO Boost GB40 covers that range.

This fits drivers of larger 12V vehicles who value repeated jump attempts and device backup in one pack. Allow time for its six-hour recharge, and account for its 2 kg weight when choosing where to store it.

NOCO Boost GB40

#2 · Best Compact Pick

2. NOCO Boost GB40

  • Voltage: 12 V
  • Battery Capacity: 2150 milliamp hours
  • Compatible with Vehicle Type: ATV, Motorcycle, Passenger Car, RV, Tractor…

Best for: Compact everyday vehicle kit.

Why it ranks #2: This 2.4-pound, 1,000A model supports up to 6.0L gas and 3.0L diesel engines and claims up to 20 starts per charge.

Up to 20 starts per charge gives the NOCO Boost GB40 useful reserve for repeated roadside attempts, while its 1000-amp output supports engines up to 6.0L gas and 3.0L diesel. It also pairs jump-starting with a phone-and-tablet power bank in a 2.4-pound package.

Spark-proof and reverse-polarity protection help guide safer connections to 12V vehicles, a practical safeguard when jump-starting without another car nearby. Its integrated power bank can supply emergency power to phones and tablets, and the unit recharges in three hours. At 2.4 pounds, it is easier to keep in a vehicle than a heavier jump box, while the 20-start rating offers reserve for more than one emergency. Its engine limits make it a better fit for everyday cars and moderate-size trucks than larger engines.

Pros
  • 1000 peak amps for engines up to 6.0L gas and 3.0L diesel
  • Up to 20 starts per charge
  • Spark-proof and reverse-polarity protection
  • Integrated power bank recharges in three hours
Cons
  • Rated engine capacity stops at 6.0L gas and 3.0L diesel.

Skip it if you need to start engines beyond 6.0L gas or 3.0L diesel; the NOCO Boost GB70 supports larger engines.

Choose this for a glove-box or roadside kit serving cars, motorcycles, and moderate-size trucks, especially when phone backup matters. Its 6.0L gas and 3.0L diesel ceiling rules it out for larger engines.

GOOLOO GT4000S

#3 · Fastest Recharge

3. GOOLOO GT4000S

  • Voltage: 12 V
  • Battery Capacity: 20000 milliamp hours
  • Compatible with Vehicle Type: Lawn Mower, Van, Watercraft, Passenger Car…

Best for: Fast-recharging multi-vehicle kit.

Why it ranks #3: Its 4,000A peak output and stated 60 starts per charge suit frequent use; the listing says a full recharge takes 1.2 hours.

The GOOLOO GT4000S can fully recharge from empty in 1.2 hours using 100W fast charging, making quick turnaround its defining convenience. Its 4000A peak output and claimed 60 starts per full charge pair that fast refill with substantial jump-start reserve across a wide range of listed vehicle types.

A 100W car charger is included, and the stated five minutes of charging can provide enough power to start a car, a useful option when a pack is depleted on the road. Full charging takes 1.2 hours, while a full charge is claimed to deliver 60 starts. The same 100W two-way charging capability can power a MacBook or other laptop. Compatibility spans vehicles including cars, trucks, motorcycles, watercraft, and RVs, and the unit is stated to operate from -20°C to 60°C.

Pros
  • 4000A peak output
  • Fully charges in 1.2 hours at 100W
  • Claimed 60 jump-starts per full charge
  • 100W two-way charging for laptops
Cons
  • The stated operating range is -20°C to 60°C.

Skip it if you need a unit with a stated engine-size limit rather than broad vehicle compatibility; the GOOLOO GP3000 specifies 9L gas and 7L diesel.

Pick this for drivers who prioritize quick recharging, laptop power, and broad vehicle coverage in one pack. Its stated operating range is -20°C to 60°C, a boundary to consider for conditions outside that span.

Povasee A30

#4 · High Engine Capacity

4. Povasee A30

  • Voltage: 12 V
  • Battery Capacity: 20000 milliamp hours
  • Compatible with Vehicle Type: All of the above

Best for: Low-voltage recovery and high reserve.

Why it ranks #4: The 5,000A jump starter is rated for 10L gas or 8L diesel engines and claims about 60 starts per charge.

The Povasee A30’s RST button can help restart engines when battery voltage falls below 9V, a specific recovery feature paired with 5000A peak output. It is rated for engines up to 10L gas or 8L diesel and claims about 60 quick starts per charge, with a 74Wh power bank for charging devices.

The below-9V RST function addresses a particularly depleted battery, while the 5000A output is rated for engines up to 10L gas and 8L diesel. Its claimed 60 starts per charge can suit drivers who want substantial reserve, and the 74Wh capacity with two USB outputs adds device charging. At 1.1 pounds and with a storage box included, it is manageable to keep in a vehicle. The package includes a USB-to-Type-C cable without an adapter, so plan charging around that included cable.

Pros
  • 5000A peak output for engines up to 10L gas and 8L diesel
  • RST button for battery voltage below 9V
  • About 60 quick starts per charge
  • 74Wh power bank with two USB outputs
Cons
  • USB-to-Type-C cable is included without an adapter.

Skip it if you want rapid two-way charging for a laptop; the GOOLOO GT4000S supports up to 100W two-way charging.

This suits drivers facing deeply discharged batteries who want the RST function, high engine limits, and USB device power. Its included cable has no adapter, so arrange a compatible charging source separately.

GOOLOO GP3000

#5

5. GOOLOO GP3000

  • Voltage: 12 V
  • Battery Capacity: 16000 milliamp hours
  • Compatible with Vehicle Type: ATV, Lawn Mower, Motorcycle, Passenger Car…

Best for: Cold-weather low-voltage starts.

Why it ranks #5: Its 3,000A output is rated for 9.0L gas and 7.0L diesel engines, with a listed BOOST mode for batteries below 9V.

The GOOLOO GP3000 combines 3000A peak power with a BOOST mode that activates when battery voltage drops below 9V, helping address dead-battery starts. It is rated for 9.0L gas and 7.0L diesel engines and is stated to work even at -4°F, a useful combination for cold-weather vehicle kits.

Its BOOST mode is specified to activate below 9V, giving drivers a recovery option when a battery is especially depleted. The 3000A output supports engines up to 9.0L gas or 7.0L diesel, while the stated -4°F operation makes it relevant to cold-weather roadside storage. A 16,000mAh capacity adds reserve, and the supplied smart jumper cable and cloth bag help keep the starter and connection hardware together. It also lists compatibility with vehicles such as cars, trucks, motorcycles, and ATVs.

Pros
  • 3000A peak output for engines up to 9.0L gas and 7.0L diesel
  • BOOST mode for batteries below 9V
  • Stated operation at -4°F
  • 16,000mAh capacity with smart jumper cable
Cons
  • Engine coverage stops at 9.0L gas and 7.0L diesel.

Skip it if you need a higher stated gas-engine ceiling; the AVAPOW A68 lists support for gasoline engines up to 12.0L.

This is a fit for drivers who want a low-voltage boost mode and a stated cold-weather operating point. Keep its 9.0L gas and 7.0L diesel limits in mind when matching it to an engine.

WOLFBOX MegaVolt24

#6

6. WOLFBOX MegaVolt24

  • Voltage: 12 V
  • Battery Capacity: 6000 milliamp hours
  • Compatible with Vehicle Type: Passenger Car

Best for: High-output passenger-car booster.

Why it ranks #6: This 4,000A model lists support for 10L gas and diesel engines and includes a 65W quick charger, though other use details are limited.

The WOLFBOX MegaVolt24 pairs 4000A peak output with a 65W quick charger, giving passenger-car owners a high-output jump box with a specified fast-charging accessory. Its title also states support for engines up to 10L gas or 10L diesel, while an LED display and light add useful emergency visibility.

The 4000A peak rating and stated 10L gas and 10L diesel engine limits make this a candidate for passenger-car owners seeking substantial starting output. Its 65W quick charger gives the package a defined charging capability, while the LED display provides a readout during use. The built-in LED light adds illumination for roadside tasks. At 3 pounds and 9.33 inches long, it is a substantial portable unit rather than a tiny pocket accessory; the listed vehicle compatibility is passenger car.

Pros
  • 4000A peak output
  • Title specifies engines up to 10L gas and 10L diesel
  • 65W quick charger
  • LED display and LED light
Cons
  • Listed vehicle compatibility is passenger car.

Skip it if you need a jump starter explicitly listed for motorcycles, trucks, or boats; the NOCO Boost GB70 lists those vehicle types.

This suits passenger-car drivers seeking high peak output, a display, and a light in one portable pack. Its listed compatibility is passenger car, so buyers outfitting other vehicle types should consider that boundary.

AVAPOW A68

#7 · Highest Peak Output

7. AVAPOW A68

  • Voltage: 12 V
  • Battery Capacity: 24000 milliamp hours
  • Compatible with Vehicle Type: Passenger Car

Best for: High-capacity large-engine backup.

Why it ranks #7: Its listed 6,000A peak output leads this group, and the product is rated for gasoline engines and diesel engines up to 12.0L.

The AVAPOW A68’s 6000A peak output is rated for all gasoline engines and diesel engines up to 12.0L, giving it broad stated engine coverage. Its description says it can jump-start a fully depleted 12V battery in as little as two seconds, making rapid response central to its appeal.

The 6000A peak rating and 12.0L diesel ceiling make this a high-output option for drivers with larger engines, while its listed vehicle applications include cars, trucks, motorcycles, boats, RVs, tractors, and lawn equipment. The two-second claim for a fully depleted 12V battery points to a fast-start workflow in an emergency. At 4.7 pounds and with dimensions of 6.06 by 10.98 by 5.63 inches, it takes more storage space and heft than a small pocket-size booster, so plan its location in the vehicle.

Pros
  • 6000A peak output
  • Rated for all gasoline engines and diesel engines up to 12.0L
  • Claimed start response as little as two seconds
  • Listed for cars, trucks, motorcycles, boats, RVs, tractors, and lawn equipment
Cons
  • At 4.7 pounds, it is heavier than a small pocket-size booster.

Skip it if you want a lighter pack for engines up to 10L gas and 8L diesel; the Povasee A30 weighs 1.1 pounds and covers that range.

Consider it for owners of large-engine vehicles who value the stated 6000A output and broad application list. Its 4.7-pound weight and larger dimensions make storage space an important fit consideration.

8. S ZEVZO ET05

  • Voltage: 12 V
  • Battery Capacity: 10000 milliamp hours
  • Compatible with Vehicle Type: Lawn Mower, Motorcycle, Passenger Car

Best for: Compact emergency start-and-light pack.

Why it ranks #8: The 5,000A model is rated for 7.2L gas and 5.5L diesel engines and includes an LCD display and three-mode flashlight.

The S ZEVZO ET05 pairs 5000A peak current with an LCD display and a three-mode flashlight, combining jump-start output with at-a-glance information and roadside illumination. It is rated for 12V engines up to 7.2L gas and 5.5L diesel and is stated to operate from -4°F to 140°F.

Its 5000A peak output is specified for 12V vehicles with engines up to 7.2L gas or 5.5L diesel, covering the listed passenger-car, motorcycle, and lawn-mower uses. The LCD display provides a visible readout, while three flashlight modes add illumination for roadside tasks. A 10,000mAh battery and USB ports extend its role to device charging. The stated -4°F to 140°F operating range offers a broad temperature window, and the supplied jumper clamps and USB-to-Type-C cable provide key connection and charging accessories.

Pros
  • 5000A peak output for engines up to 7.2L gas and 5.5L diesel
  • LCD display
  • Flashlight with three modes
  • 10,000mAh capacity and USB ports
Cons
  • Rated engine limits stop at 7.2L gas and 5.5L diesel.

Skip it if you need a higher diesel-engine ceiling; the GOOLOO GP3000 is rated for engines up to 7.0L diesel.

This fits drivers wanting a displayed readout, flashlight modes, and USB power in a 12V emergency starter. Its 7.2L gas and 5.5L diesel limits are the key boundary when matching it to a vehicle.

DEWALT DXAELJ18C

#9

9. DEWALT DXAELJ18C

  • Voltage: 12 V
  • Battery Capacity: 3.7 amp hours
  • Compatible with Vehicle Type: Passenger Car, Truck

Best for: USB-C roadside charging kit.

Why it ranks #9: It offers 1,800 peak amps, smart jumper cables and USB-C PD input and output, but the supplied engine guidance is less specific.

A 30W USB-C Power Delivery input and output gives the DEWALT DXAELJ18C a clear advantage for charging compatible devices alongside its 1800 peak-amp starting function. It supports most 4-, 6-, and 8-cylinder cars and trucks with 12V WET, GEL, or AGM lead-acid batteries.

The 1800 peak amps provide portable starting power for most 4-, 6-, and 8-cylinder cars and trucks without another vehicle, making it useful for a roadside kit. Its 30W USB-C PD input and output, together with a 15W USB-A output, also supports device charging. Reverse-polarity protection helps guard against incorrect cable connections, while the compact format and included case make storage in a garage or vehicle more practical. Battery compatibility is specifically stated for 12V WET, GEL, and AGM lead-acid types.

Pros
  • 1800 peak amps for most 4-, 6-, and 8-cylinder cars and trucks
  • 30W USB-C PD input and output
  • 15W USB-A output
  • Reverse-polarity protection and included case
Cons
  • Compatible battery types are limited to 12V WET, GEL, and AGM lead-acid.

Skip it if you need support for an engine beyond the stated 4-, 6-, and 8-cylinder range; the WOLFBOX MegaVolt24 specifies up to 10L gas or diesel.

Choose it for a car-or-truck emergency kit where USB-C PD charging and a case are useful alongside jump-starting. Check that your vehicle uses a supported 12V WET, GEL, or AGM lead-acid battery.

Schumacher SL1639

#10

10. Schumacher SL1639

  • Voltage: 12 V
  • Battery Capacity: 1000 amp hours
  • Compatible with Vehicle Type: Lawn mower, ATV, JetSki, Snow mobile…

Best for: Glove-box emergency light kit.

Why it ranks #10: Its 1,000A output is rated for engines up to 8.0L gas and 6.0L diesel, but the listed starting power is lower than most alternatives.

A slim, 1.53-inch-deep profile lets the Schumacher SL1639 fit into a glove box, purse, or backpack while supplying 1000 peak amps. Its stated engine coverage reaches 8.0L gas and 6.0L diesel, and the built-in LED flashlight adds steady, SOS, and strobe modes for roadside use.

The combination of jump starter, USB power bank, and three-mode emergency light makes this a compact kit for drivers who want several roadside functions in one device. Its 1000-amp output is rated for engines up to 8.0L gas and 6.0L diesel, covering a broad range of cars, SUVs, trucks, motorcycles, and ATVs. A four-hour recharge gives a clear maintenance interval after use. At 14.18 inches long, its narrow profile favors vertical storage in a bag or vehicle compartment.

Pros
  • 1000 peak amps for engines up to 8.0L gas and 6.0L diesel
  • Flashlight offers steady, SOS, and strobe modes
  • USB power-bank function
  • Narrow 1.53-inch depth suits compact storage
Cons
  • Recharging fully takes four hours.

Skip it if you need more than 1000 peak amps for your engine; the NOCO Boost GB70 offers 2000 peak amps and larger stated engine limits.

Consider it for drivers who want a narrow-storing jump pack with USB charging and emergency light modes. The four-hour recharge and 1000-amp output are boundaries to weigh for frequent use or demanding engines.

What peak amps cannot tell you

Peak amps alone do not tell you whether a jump starter will work with your vehicle or under every condition. The listed engine limits vary: the NOCO Boost GB40 is rated for up to 6.0L gas and 3.0L diesel engines, while the NOCO Boost GB70 lists 8.0L gas and 6.0L diesel. Other models advertise higher limits, including the AVAPOW A68 at up to 12.0L diesel, but do not assume that a larger peak-amp number automatically makes a unit compatible with every battery or vehicle.

Check the product’s exact engine guidance, your vehicle’s 12V system and battery type, and the supplied instructions. A model’s stated ability to handle low battery voltage is also distinct: the GOOLOO GP3000 lists BOOST mode below 9V, and the Povasee A30 describes an RST button for voltage below 9V.

Those details do not guarantee a start in every failure condition.

Plan for storage and a failed first attempt

A jump starter is only useful in an emergency if it has charge and its clamps are connected as directed. Some product listings state recharge times or starts per charge: the NOCO Boost GB40 lists up to 20 starts and a three-hour recharge, while the NOCO Boost GB70 lists up to 40 starts and a six-hour recharge. The GOOLOO GT4000S claims up to 60 starts and a 1.2-hour full recharge.

These are product claims, not a guarantee of real-world performance in every condition. Keep the unit charged using its instructions, and inspect cables and clamps before an emergency.

If the first attempt fails, do not repeatedly crank without following the manual; check clamp placement and the vehicle’s requirements, then consult roadside assistance or a qualified technician if needed. Lithium jump packs offer portability and may include power-bank features, but they are not substitutes for diagnosing a failing battery or vehicle charging system.

How to Choose a Lithium Jump Starter

Engine size and fuel type

Look for a model whose stated engine limits cover your vehicle’s engine and fuel type. The NOCO Boost GB40 lists up to 6.0L gas and 3.0L diesel, while the NOCO Boost GB70 lists up to 8.0L gas and 6.0L diesel. The Povasee A30 lists 10L gas and 8L diesel, and the AVAPOW A68 lists diesel engines up to 12.0L.

These are different manufacturer claims, so do not treat peak amps as a replacement for checking compatibility. Drivers of smaller passenger cars may prefer a compact unit with a suitable stated limit; owners of larger engines should prioritize a model explicitly rated for their displacement and fuel type.

Peak output and battery capacity

Compare peak output alongside battery capacity and the product’s stated starts per charge, rather than choosing by one number. Listed output ranges from 1,000A on the NOCO Boost GB40 and Schumacher SL1639 to 6,000A on the AVAPOW A68. Battery capacity ranges from 2,150mAh on the GB40 to 24,000mAh on the AVAPOW A68; some listings also state intended starts, such as up to 40 for the NOCO Boost GB70 and 60 for the GOOLOO GT4000S.

The lower end can suit drivers seeking a compact emergency unit for an appropriately sized vehicle. Those who want more output or more stated charge capacity can compare the higher-end models, while verifying engine limits separately.

Charging and emergency extras

Choose extras that match how you expect to use the pack, and check the exact charging details. The NOCO Boost models include a power bank; the Schumacher SL1639 adds an LED flashlight with steady, SOS and strobe modes. The DEWALT DXAELJ18C lists 30W USB-C PD input and output and 15W USB-A output, while the GOOLOO GT4000S advertises 100W two-way charging and a 1.2-hour full recharge.

The WOLFBOX MegaVolt24 lists a 65W quick charger. For drivers who also need to charge devices, prioritize the listed ports and output.

If readiness between uses is the main concern, compare stated recharge time and follow the manufacturer’s storage and charging guidance.

Which Lithium Jump Starter Should You Choose?

For a balanced choice with substantial stated engine coverage and built-in safeguards, choose the NOCO Boost GB70: it lists 2,000A, up to 40 starts per charge, and support for engines up to 8.0L gas or 6.0L diesel. For a smaller unit for compatible vehicles, the 2.4-pound NOCO Boost GB40 lists up to 20 starts. Frequent users who value fast recharging can consider the GOOLOO GT4000S, which claims a 1.2-hour full charge and 60 starts.

For a larger diesel engine, compare the engine limits of the Povasee A30 and AVAPOW A68 against your vehicle’s specifications. If charging electronics is a priority, the DEWALT DXAELJ18C lists USB-C PD input and output.

Confirm compatibility and follow the jump starter’s instructions before use.

Frequently Asked Questions

How often should I recharge a lithium jump starter when it is stored in a car?

Follow the manufacturer’s charging schedule, since storage guidance varies by model. Check the charge level periodically and recharge it before it becomes depleted; also top it up after use. Heat and cold in a parked car can affect batteries, so consult the manual for storage-temperature limits and avoid leaving the unit in conditions it prohibits.

Can a portable jump starter damage a car’s electronics if connected incorrectly?

Yes, an incorrect connection can create a risk of damage, which is why you should follow the jump starter’s instructions and your vehicle’s manual. Check terminal polarity carefully, use the designated connection points, and do not proceed if you are unsure. Built-in protections are helpful, but they do not replace correct setup.

What should I do if a jump starter does not start a vehicle on the first attempt?

Stop and check the connection, clamp placement, and the jump starter’s charge level before trying again. Follow the device’s instructions for any pause between attempts, and avoid repeated or prolonged cranking. If the vehicle still will not start, stop troubleshooting and seek assistance; the battery, connections, or another vehicle system may need attention.

How can I tell whether a jump starter is compatible with my vehicle?

Compare the unit’s stated engine limits and voltage with your vehicle’s requirements before buying or connecting it. Check both fuel type and engine size, and confirm any vehicle-specific instructions in the owner’s manual. If the listed limits do not clearly cover your vehicle, contact the manufacturer or a qualified technician rather than guessing.

What features matter if I want a jump starter to charge other devices?

Look for the ports and charging capabilities stated for the model, then match them to the devices you plan to charge. For example, the DEWALT DXAELJ18C lists USB-C PD input and output. Check the jump starter’s instructions for supported connections and charging use, and keep its charge level adequate for its intended roles.

Final Words

Choose based on your vehicle’s engine requirements, how often you expect to use the unit, and whether portability or device charging matters. The NOCO Boost GB70 is the balanced pick in this roundup, with stated support up to 8.0L gas or 6.0L diesel and built-in safeguards. Consider the GB40 for a smaller compatible option, the GT4000S for frequent use, or compare larger-engine limits carefully.

Confirm compatibility and follow the instructions before use.
